Hot off the press: Latest news from your local Chippie

I’m in Western Australia this week visiting my home town of Perth and discovered yesterday a clever healthy option for fast food snacks: Fit Chips.

Nutritionists recommend that hot potato chips are only eaten sometimes because they are high in fat and calories. So, two Mums in Perth set about to make a healthier alternative by using canola oil and specialised ovens that blast the chips with hot air instead of deep-frying them.



Fit Chips make a healthier alternative to the regular chip because they have 35% less calories and less than half the fat of regular chips, either from a take-away shop or the frozen ones from the supermarket.


Also, because they’re made with canola oil they have only a quater of the saturated fat of regular chips which makes them a good choice for people looking after their heart health (that’s all of us, right?). Fit Chips also have alternative shaker toppings so you can reduce the amount of salt. As a low-salt alternative you can choose salt-free shakes of cracked pepper or red chilli flakes.

Even though Fit Chips are lower in fat, calories and salt, it is still a good idea to have them only sometimes. If you’re looking for healthier everyday snack ideas check out my post on healthy snacking.

Proof: Dietitians do indulge


On a recent weekend away in celebration of the shortest day of the year here in the Southern hemisphere we had a 'Dark Days Dinner'. I thought I'd share with you the recovery breakfast to prove that dietitians (there were 3 of us on this getaway) do indulge occasionally.

The Canuck explains how to prepare the Edinburgh-inspired French toast, bacon and brie breakfast.



Note: I did have to run inside to the fridge to grab the whipped cream just to make the dish complete! (as part of a balanced diet)

Pumping up on Protein


With all the training we’ve been doing lately for our Dragonboat National Titles I noticed some of our team mates have been using the supplements from those giant tins you see in the supplement stores. As an amateur sportsperson maybe you’ve used them. But how do you know if you need protein supplements?

While a meal replacement that contains carbohydrate and other nutrients as well as protein can be part of a well-balanced diet when you’re training, it’s a good idea to know how much protein you need to eat so that you’re not wasting time and money pumping up on unnecessary extra protein.


Protein – what’s it good for?

Protein foods are an important part of everyone’s diet because they are used by the body to make a whole range of metabolic essentials like hormones and immune cells as well as muscle cells.

The more exercise you get, the more protein you need in your diet. This is because the protein is used to fuel exercise and to help repair and grow muscle after exercise. If you exercise regularly you’ll need around 1g of protein each day per kilo of body weight. Athletes need more protein, between 1.2 and 2.0g per kilo.


So a 85kg (187 pound) man exercising regularly will need 85g of protein but if he took up athletic level training he may need between 102
– 170g of protein each day. Most athletes eat more when they are in training and it has been shown that they actually eat enough protein-rich foods to get the extra protein they need with 3 meals and snacks each day.

Eating enough protein for athletic training doesn’t mean eating steak 4 times a day. Other foods that are good sources of protein include milk, yoghurt and cheese, eggs, nuts and legumes (baked beans, lentils, kidney beans, tofu). Cereal based foods like bread, pasta and breakfast cereal all contain some protein as well.


A typical day for our 85kg athlete in training might look like this:
Pre training snack: Glass of low fat milk ............... 10g
Breakfast:
2 cups cereal with
low fat milk .............................. 15g
2 pieces of wholegrain toast with jam .....................10g
Snack: Banana smoothie with yoghurt ....................15g
Lunch: Ham, cheese and salad roll ........................ 30g
Snack: Chocolate milk & Cereal bar........................ 17g
Post triaining snack: Mixed nuts & sports drink ........12g
Dinner:
Beef, veg and kidney bean bolognaise sauce.............30g
2 cups pasta ...................................................... 10g
Apple crumble with low fat custard ......................... 9g

Total 158g protein (1.85g / kg)

Before you mix up that ‘Mega-supa-muscle-enhancing shake’ providing large amounts of protein just remember that eating any more protein than 2g/kg/day will not build new muscle tissue. Your body will just use the extra protein for energy and you may be eating so much protein you miss out on other important nutrients. Protein-rich foods provide a range of nutrients not found in supplements including vitamins, minerals, phytochemicals and antioxidants.



Reducing the aches and pains after training

If you are training for an event, timing when you eat is as important as how much you eat. To help fuel exercise and aid recovery, eat a carbohydrate snack with 10-20g of protein before and after (within 15 – 60 minutes) training sessions.

Some examples of snacks for pre and post training:
  • 375mL low-fat chocolate milk and a banana (14g protein)
  • Small tub of yogurt and fruit (11g protein)
  • Peanut butter and jam wholegrain sandwich (14g protein)
  • 60g mixed nuts and dried fruit (12g protein)

So, do I need a supplement?

You don't need a supplement to get enough protein. However, if you like the convenience of a liquid snack,
choose a meal replacement that has both carbohydrate and protein as well as some vitamins and minerals, particularly calcium.


If you are training for an event and would like more advice on maximizing the benefit of the foods you eat during training and competition, contact a sports dietitian. Contacts can be found on my links page.
Good luck!

How much is that burger in the window?

A few weeks ago on a road trip after a weekend Dragonboat regatta in the country the only food available was a fast food chain. My friend looked guiltily at me and said “I guess you won’t be able to eat anything” as if the mere sight of fast food would cause me to go into some sort of fit requiring a dash to the nearest hospital. You’ll all be happy to know that I do eat fast food sometimes and survive to tell the tale!

Like a lot of dietitians I love to cook, but it’s not always possible to cook a meal at home and fast food is a convenient option. For a healhty diet it’s best to limit your visits to fast food places to once a week or less. Smart choices at the counter can also make a big difference. As of February this year people in New South Wales (the state in Australia where I live) will start to see more information that will help them make that choice. New laws have just been passed so that by February 2012 all large fast food chains will have to show the kilojoule content of all food on the menu. Those of you in many places around the world have had this for some time.

So what do the numbers mean?
The kilojoule (kJ) content of a meal is the amount of energy the food provides. Kilojoules are the metric equivalent of calories and one Calorie is equal to almost 4.2 kilojoules.
It’s hard to know how many kilojoules are in a meal just by looking at it so lablelling a menu can help. For example a small hamburger is around 1000 kJ while the larger ones can be 3000kJ. A muffin can be anywhere from 500kj to 2000kJ.

The 2-7-2 Guide

When you're looking at the menu kilojoules on the menu, how do you make a choice? Try the 2-7-2 guide: 2,000kJ for each meal and 700kJ for each snack. This way 3 meals and 3 snacks roughly adds up to the average adult daily intake of 8700kJ. Remember this includes drinks like coffee, alcohol and soft drinks (soda).


So when you're standing at the counter making your order a good choice is one that will provide around 2,000kJ including the drink. Then you can enjoy your meal knowing you've made a healthier choice.

At this stage the labelling in NSW is only energy but it may soon also include fat and salt content as is the case in some places around the world. In this case choose foods lower in fat and salt if possible.

How much do you need?
We all need energy from food but how much you need everyday depends on individual differences including your age, gender, how active you are and your weight. So it makes sense that we might need more or less than the average 8700kJ. An active 30 year-old man would need more than his 70 year old gran who walks to the shops each day.


As a rough guide the kilojoule values below give a idea of the amount of energy you need each day. The lower values are for people that don’t get much exercise each day. The higher values are for people that work in very physical jobs or do sports training for many hours each day. If you get at least 30 minutes of exercise each day you are likely to fall somewhere in between these values.

Women under 60 years need between 8,000kJ and 10,000kJ

Women over 60 need between 6,000 and 9,000kJ

Men under 60 need between 10,000 and 15,000kJ
Men over 60 need between 8,000 and 12,500kJ


These values are just a guide. For a closer estimate of the kilojoules you need each day try this online tool or talk to an Accredited Practising Dietitian.

If you live in an area that has been labeling fast food menus for some time I’d love to hear about if it has changed the choices you make.

Healthy habits here we come!



Happy New Year! The Canuck has decided that this year is ‘the year of tennis’ for the two of us and 10 days into 2011 he’s already booked us in for a social tennis group on Saturdays at a club up the road. I’m thinking that after a Christmas of home-baked goodness a lot of us are making some similar changes in an effort to shed the extra kilos.


Aim for healthy habits rather than crash diets

As the saying goes, every journey starts with the very first step. So, if you are aiming to lose some weight, rather than ‘going on a diet’ and radically changing what you eat, try to think of a small change that you can make today and keep doing until it becomes a healthy habit. By aiming for healthy habits you are more likely to make changes that will last and be better for your health as well as your waistline. If you are trying to cut down on fat then start today by swapping to a reduced fat milk today. Try doing that every day for a week or two and before you know it you’ll be choosing low fat milk at the supermarket without thinking (low fat dairy products are recommended for all the family over 2 years old).

I have to mention here that after reading my previous blog post on whole grains my friend Pren has done exactly this and now has a healthy habit of choosing grain bread rather than white. So it can be done!

Losing the extra ‘fruit mince pie kilos’

It's not rocket science: most of us know it comes down to fewer calories in and getting more physically active; but that’s easier said than done sometimes!


If you can find a couple of small things you could change that would reduce your total intake by 500 calories each day you would be on the way to steady weight loss. You don’t need to count every calorie of every food you eat, just make one or two changes as a start.

Some places that you might find that 500 calories lurking:

A café muffin 500 calories

A large flat white coffee or latte 220 calories
A 50g (small) pack of chips (crisps) 250 calories

A can of soft drink (soda) 150 calories

Two chocolate biscuits 200 calories

A 55g chocolate bar 250 – 300 calories

1 glass of wine 150 calories


So if you swapped your breakfast of a regular flat white coffee and muffin to a skinny flat white and piece of fruit toast and had water rather than a soft drink you’d be having 500 calories less each day.

Vegetables are packed with nutrients without excess calories so another way to cut back on calories without getting hungry is to eat plenty of veggies. At meals, aim for your plate to be ¼ lean meat or other protein, ¼ carbohydrate and ½ vegetables of different colours for a variety of nutrients.

Remember to be realistic about your weight loss. The most effective way to lose weight and keep it off is slowly and steadily. By aiming for half a kilo each week (about a pound a week) you’re being realistic and are more likely to stick to those healthy habits.

One of the biggest intervention studies ever conducted in nutrition recently found that the most effective eating pattern for keeping off the extra kilos once you’ve lost weight was eating a little more protein and choosing lower glycaemic index foods (like grain bread instead of white and sweet potatoes rather than white potatoes).

Move that body

Another great healthy habit to pick up in the New Year is adding in a little more physical activity. People that lose weight and keep it off are most often the ones that get 60 minutes of exercise each day, including walking to train station, walking home with the kids after school or meeting a friend for a bike ride before you go for coffee (or, like the Canuck, joining a local social tennis group). Why not get 20 minutes exercise tomorrow work your way up to 60 minutes by March?

If you are in Australia, look out for Healthy Weight Week activities January 23 - 30, 2010. For individual advice on weight loss make an appointment to see an Accredited Practising Dietitian

If you have a healthy habit goal for 2011 post a comment below to let me know how it's working out.

Waste not want not


My first Bokashi compost is ready! So in typical science-geek fashion I started a small experiment on our balcony this spring. One citrus tree (affectionately known as Lily the Lemon) and 3 of my tomato plants are feeding on a smorgasbord of potting mix and Bokashi compost. The lime tree (Lenny) and the other tomatoes are my control group: they get regular potting mix but no compost goodness.

Balcony ‘kitchen gardens’ are a great way to have a ready supply of fresh herbs, fruit and vegetables packed with nutrients and flavour. On my balcony in Sydney I find basil, parsley, rosemary as well as tomatoes and citrus fruit grow really well. To be more environmentally-friendly I wanted to compost our food scraps but living in an apartment this is difficult. I was thinking of setting up a worm farm but was worried that the red wigglers would pass out in the heat on our balcony in summer so I thought I'd give Bokashi a go.

So, a few months ago the Canuck fashioned some home-made composting buckets and we started our apartment Bokashi composting. Bokashi is a composting system developed in Japan for people to use in apartments. It works by adding some Bokashi mix (wheat bran with rice husks and microorganisms) each time you add food scraps to your indoor compost bucket. The microbes do their thing and ferment the food so it smells kind of vinegary but not nasty (important when it’s kept inside your apartment). After a few weeks the Bokashi and food mixture can be buried in soil. After 6 weeks in the soil all the food has broken down and it just looks like regular soil. You now have nutrient-rich soil that can be added to your potted plants.

Back to my experiment….
It’s been a month since I started my experiment and I have to say that the plants that had the compost added to their soil are jumping out of their skins. Lily the Lemon is sprouting a load of flowers and the tomato plants are twice the size of the ones that didn’t have any compost (pictured above). In the meantime we’ve reduced our rubbish by about half and I don’t have to buy fertilizer. I’m taking that as a success!

If you have a kitchen garden on your balcony I’d love to hear your handy tips on growing herbs, fruit and veg in small spaces, just leave a message below.

The Benefits of a Frequent Fibre Program


A few months ago my Aunt commented that I was too young to be eating a high fibre breakfast cereal. I guess she figured that the only people that needed high fibre were the type of 60+ oldies they show on TV ads about ‘keeping you regular’.



Fibre doesn’t seem nearly as sexy and interesting as omega-3s or antioxidants, but by starting a high fibre diet while you’re young you can actually increase your chances of staying healthier for longer. People that eat more fibre are 33% less likely to develop diabetes and 14% less likely to suffer a heart attack or stroke.


As part of my research project for my Masters degree (just finished – yay!) I reviewed the research on how fibre can help you keep a healthy weight and lower blood pressure. What I found was that people who eat a high fibre diet are less likely to put on weight. High fibre foods tend to be bulky, with lots of nutrients but not many calories (think of a big plate of vegetables). This means that they fill you up and you tend to eat less calories in total, making you less likely to put on weight.

I also found that cereal fibre can help people with high blood pressure reduce it by as much as 7mmHg, even when they are on medication. To put that in perspective that is the same effect as a low salt diet, the first change recommended by your doctor to lower blood pressure. So there are a lot of benefits to a high-fibre diet even before your 60th birthday.

How much fibre do you need?
To help prevent heart disease the Australian and other international guidelines recommend women eat 28 grams of fibre each day and men 38 grams.

Most Australians don’t eat enough fibre. The average Australian woman eats about 20g of fibre per day and the average man eats about 26g. This means that most of us could benefit from an extra 10g of fibre each day.


Not to worry, you don’t have to eat horse chaff three meals a day to get that much fibre – it’s found it lots of foods and, as always, variety is the key. Nuts, wholegrain foods, bran, legumes (kidney beans, chickpeas, lentils) all have fibre. Two serves of fruit and 5 serves of veggies also adds lots of fibre to your day.


If you think back to my wholegrain post you might remember that the bran layer of a grain has lots of fibre but this is removed when a food is refined, so by choosing wholegrain you are often choosing high fibre.

Your high fibre day might look like this:
Breakfast: A bowl of high fibre cereal (more than 3g per serve) with milk with strawberries (5 grams)

Snack: A handful of unsalted nuts (3 grams)

Lunch: Tuna and salad wholemeal sandwich with a piece of fresh fruit (10 grams)
Snack: 2 wholegrain crispbreads with low fat cream cheese (3 grams)

Dinner: 1 cup of whole wheat (brown) pasta with beef and kidney bean bolognaise sauce and a cup of mixed salad (14g)

A low-fat frozen yoghurt bar


Too much of a good thing

Before you race out and buy an extra large pack of fruit and nuts remember that it’s a good idea to gradually increase the fibre in your diet otherwise you can get a bit uncomfortable. Go for swapping one low fibre food for a high fibre option each week until you reach your goal. As always, drink plenty of water (at least 1L) and get some exercise each day.
More than 40g every day can stop you from getting the calcium and iron from other foods so remember moderation and variety are the key.

Wholesome wholegrains



You may have noticed a new word cropping up more often on food packaging lately: wholegrain. So why would you choose a wholegrain food and why is it being talked about on food labels these days?




Well, first of all a quick word about food research. Our knowledge of how food affects our health is constantly improving. For example, about 25 years ago we started to realise that not all fats are the same, and we started to see a difference between saturated, monounsaturated, polyunsaturated... well, you get the idea. Today, researchers have found that with carbohydrates, the type of carbohydrates we eat may be just as important as the amount.


This recent research has shown that replacing refined grains with wholegrains decreases your risk of obesity, heart disease and diabetes. Also, the natural chemicals called phytoestrogens may protect against some cancers. On top of all that, the fibre in wholegrains helps keep you regular.

As a result of this research, guidelines in the USA suggest people eat at least half of their breads and cereals as wholegrain. Next year, the revised guidelines for Australians are also expected to recommend that people eat more wholegrains and limit refined grains.


What is a wholegrain?
Wheat, oats, corn, rice, barley and rye are all grains. These are made into foods such as bread, cereal and pasta. They are grouped together because the grains are seeds on a grass-type plant.

The grain is made of three parts: the germ, the core (endosperm) and the bran. The germ nourishes the seed with B vitamins, vitamin E and minerals as well as healthy oils and antioxidants. The inner core provides the seed with a store of carbohydrate and protein. The outside layer, the bran, protects the seed. It contains fibre as well as vitamins and minerals.

When a grain like wheat is refined to make white flour, most of the bran and some of the ge
rm is removed to leave the core which is then ground up. People started to refine grain because by removing the oils in the germ the flour could be stored for longer, and also the bread was easier to chew and digest. Interestingly, white rice is the same in that most of the bran and germ are polished away to leave only the white rice core.

Refined flour has plenty of carbohydrate and protein for energy and growth but it has less than half the B vitamins, very little of the vitamin E or minerals (iron, magnesium and zinc) and none of the fibre or healthy fats from the original wholegrain. So it’s not really surprising that wholegrains, with all the extra nutrients, are better for your health.


Where to find wholegrains

Wholegrains can be grains you can see, like in grain bread, or they can be ground up like in wholemeal bread.
Some wholegrain foods can take time to get used to because they taste a bit different and can be very filling (great for keeping a healthy weight!). It’s a good idea to add wholegrains into your diet slowly, aiming to get to at least 4 serves of wholegrains each day. The key is to swap refined grains like white bread for wholegrain foods like a grain bread.

Refined grain foods include white bread, white rice or ‘regular’ pasta, rice noodles, doughnuts, muffins, cakes


Wholegrain foods include wholemeal, rye, spelt or grain bread, brown rice, wholewheat pasta, oats, popcorn, wholewheat couscous


Some everyday ideas to swap wholegrains in and refined grains out

Breakfast
Check your breakfast cereal: is a wholegrain listed as the first ingredient?
Try porridge or muesli made with oats, or a breakfast cereal with a wholegrain as the first ingredient


Lunch

Swap your white bread sandwich to wholemeal bread or a wholegrain wrap.


Snack on a wholegrain crispbread, or wholegrain rice crackers, or snack bars with wholegrains as main ingredients (see my snack post for tips on choosing a snack)


Dinner

Try brown rice with your stir fry (it has a great nutty flavour), or
make multicoloured pasta: half wholemeal half white (just remember the wholemeal takes a bit longer to cook)
Have corn on the cob instead of a potato

Experiment with some different grains every so often like wholewheat bulgur (tabouleh) or quinoa (not technically a grain but nutritionally very similar)

Young at heart

My grandmother would have been 101 years old this week. My family was lucky enough that she stayed happy and healthy until the ripe old age of 99 so that she could share her wonderful scones, a great big smile and a hug every time we visited. Having older people as a part of our lives is important in so many ways, and to make sure they stay healthy and strong as they get older they need to continue to eat well.

Caring for an older frail person

With all the talk about obesity it is hard to imagine that there is a part of our community that is malnourished, but a large number of older people are not eating well enough to stay healthy. Australian studies have found that around 1 in 10 frail older people are malnourished. Many people have the idea that it is ‘normal’ to lose weight as they get older, but actually this makes them more likely to get sick and much harder to get well again.


People also often say that they don’t need to eat as much as they get older but in fact there are some things we need more of once we’re over 70: protein to help stop muscles wasting, calcium (see my healthy bones blog entry), folate and zinc which help in healing, as well as fluid and fibre which help avoid constipation. Also, many older people that don't go outside often don't get enough Vitamin D (see a great explanation at The Scoop on Nutrition).


There are lot of different reasons why an older person may not eat enough. It might be physical, like dentures that don’t fit properly, or difficulty opening packets; it may be emotional as they don’t like eating on their own; or they may not be able to smell or taste the food so not feel like eating. All these reasons add up to eating less, in which case it is really important that the food they do eat is packed full of energy and nutrients.


Ideas to make every mouthful count

Older people often can’t eat big meals because they have a poor appetite and get full quickly. Encourage them to eat at least three meals each day and high protein snacks as well if they’re not eating big meals.


Make sure snacks have protein like cheese and crackers, English muffin with ricotta or baked beans and toast.


If chewing is difficult suggest some softer foods like casseroles, fish or eggs
.

Remind them to drink between meals as older people don’t get as thirsty but still need to drink.


Encourage desserts, particularly ones with a milk base like rice pudding or crème caramel with tinned fruit.

Help older people eat with others; if you’re going to visit, take a meal and share it or go out for a meal. Encourage them to go to community centres that provide lunch at least once a week.


Make sure food is stored and reheated properly and that they remember how to use kitchen equipment like their microwave.


If you are worried that the person you are caring for is not able to prepare their own meals try some frozen meals or have food delivered by Meals on Wheels or Tender Loving Care.
If someone is really not eating well, a drink-based supplement might be useful; like Sustagen or Ensure which are available at the supermarket and chemist. Two glasses in a day has the same energy and protein as a roast meal. They also provide vitamins and minerals just like a balanced meal.

Grab your 'I Heart Dairy' T-shirt – it’s Healthy Bones Week!

I remember as a kid I threw myself off monkey bars in the playground and tried to convince my parents my arm was broken because I thought having a cast was cool, but apparently my bones were made of tougher stuff as I never did break a bone. This week Dairy Australia and Osteoporosis Australia are promoting us all to take some time to think about keeping our bones healthy so they don’t break when we get older.

We tend to think of bones as hard, never changing parts of our body. Actually, like some people’s houses, your bones are constantly under renovation and being rebuilt. As children, bones are built up faster than they are broken down and the bones grow. As an adult your bones stop growing but they are still constantly being broken down and rebuilt. Then, after about 45 or 50 years old the reverse starts to happen and our bones start breaking down faster than they are building up. These leads to bones becoming weak or brittle, a condition called osteoporosis. Because this is controlled by hormones osteoporosis tends to happen to women earlier and more often than men; 50% of women and 30% of men over 60 suffer from osteoporosis.

Osteoporosis is a concern because you can’t see, or feel your bones getting weak until you fall. Because the bones are brittle they break very easily. It takes a long time to recover and a lot of older people stop being able to get around and become dependent on family and friends to help them.

The good news is by eating calcium-rich foods and with regular exercise and some sunshine, you can help keep your bones stronger for longer so that you’re out playing soccer with the grandkids well into your old age!

The ‘Calcium Bank’
While many people know that calcium is one of the building blocks of bones, what they may not realize is that it’s being deposited and taken out again all the time, just like a bank account, to be used by other parts of your body. Calcium is used by your heart, muscles and nerves, so if you don’t get enough from your diet, your body will start to take some from ‘the bank’, and you may develop osteoporosis as an older adult.

It’s important to keep your ‘calcium bank’ topped up to grow and keep strong bones. Teenagers in particular need to be depositing calcium rapidly to grow bones, so it’s a concern that a recent study showed that most Australian teenagers are not getting the recommended amount of calcium*. Studies show that this can put girls in particular at risk of osteoporosis later in life.

Make a calcium deposit each day!

Australian guidelines recommend different amounts of calcium at different times in life:

Children....................... 700 mg = 3 serves of dairy or equivalent
Teenagers.....1000 –1300 mg = 3 - 4 serves

Adults........................ 1000 mg = 3 serves
Women over 51........1300 mg = 4 serves
Adults over 70...........1300 mg = 4 serves

Dairy products like milk, cheese and yoghurt have lots of calcium. If you don’t eat dairy products or are looking for more variety some alternatives are calcium-set tofu, tinned sardines or salmon (with the bones) and bok choy.

A serve might be:
a cup of (low fat) milk or fortified soy milk (skinny latte, fruit smoothie or on your cereal)
a small tub of yoghurt or rice pudding
2 slices of cheese in your sandwich or salad
1 cup bok choy
160 g tofu

Vitamin D
Vitamin D is also important for healthy bones because it helps take up calcium from our food and store it in our bones. Strangely, it’s not really a vitamin at all but a hormone made by your body and activated by sunlight on your skin. As we get older our skin is not as efficient at activating vitamin D, and without the active vitamin D our bodies don’t absorb as much calcium as when we were younger. That’s why we need more calcium than when we’re a young adult.

There has been some research results lately that show even in a sunny country like Australia people may not be getting enough Vitamin D. For a great summary of Vitamin D check out The Scoop on Nutrition post on Vitamin D.

Other things that help keep healthy bones are regular exercise, not smoking, and avoiding excess caffeine.

Snack your way to better health

The Canuck came home the other day with a muesli bar a company had been giving out at the train station as a promo. He suggested that since he had no idea how to tell if the bar was a good snack, maybe it would make a good blog topic. Full of great ideas that man.

Having a snack mid-morning and mid-afternoon can stop you from getting so hungry that you overeat at mealtimes. The problem is that a lot of the snacks we reach for have loads of salt or sugar, with no trace of any fibre, vitamins or minerals.

So how do you choose a great healthy snack?
Good healthy snacks include some carbohydrate, a little protein and not too much fat. Great healthy snacks have all this and more: some vitamins and minerals as a bonus.

If you’re buying a snack take a look at the nutrition information panel on the pack; it’s full of really useful information about all the nutrients in your snack. Things to look for are:

Energy - aim for less than 600kJ (143 Calories) in the serve.

Fat – go for snacks with less than 10g saturated fat per 100 grams

Sugars – try to avoid snacks with lots of added sugar. Around 20 – 30 grams of carbohydrate is enough for a good snack.

Salt (sodium) – a low salt food has less than 500mg of sodium per 100g

Other good stuff – try and have a snack that has one of these in it:

  • Calcium - snack time is a great opportunity to get one of your 3 daily serves of dairy (300mg of calcium per serve)
  • Fibre – snacks with fibre help to boost your fibre intake closer to the goal of 25 - 30 grams of fibre a day
  • Protein – good to have some of this in your snack as protein helps keep you full for longer so will stave off the munchies until dinner time

Give these a go
Here’s a few ideas to get you started:
  • One sushi roll
  • A small tub of low-fat yoghurt or chocolate mousse (200g)
  • A handful of nuts, about 15 almonds, with some sultanas or other dried fruit
  • A piece of fruit – cut up and use a fork if you don’t want sticky fingers
  • A piece of raisin toast or a fruit English muffin with a slice of cheese
These ideas will make sure you always have a healthy snack at hand:
  • Take a supply of healthy snacks to work to keep in your desk drawer or in the work fridge
  • Keep a couple of indestructible healthy snacks like small cereal bars or sesame snacks in your car or handbag for those times you’re hungry on the run
  • Check out the dairy section at the supermarket – there are all kinds of small packs of healthy snacks out there

Sometimes the healthy option just isn’t going to cut it
The snacks with vitamins and minerals are the ones that will give you energy and keep a spring in your step so try to go for those most of the time. But when you really need a pick me up try:

6 jelly beans
A mini chocolate bar
A Paddle Pop or Skinny Cow ice cream
A snack pack of chips (30g)


To snack or not to snack
It’s normal to sometimes feel hungry between meals, especially if the last meal was a few hours ago, but make sure you are eating because you’re hungry and not out of habit, boredom or emotions. Instead try to think of other ways to help reduce stress like a brisk walk around the block or a phone call to a friend.

...and the promo muesli bar?
Well, the cereal bar The Canuck brought home matched all the tips I listed above for a good snack except it was 800kJ so a little too much energy for a snack. On the positive side, it comes in two handy bars so if you just eat one of the bars that’s only 400kJ; perfect if you save the other for later or share with a friend!

Do you have a favourite healthy snack? I love to hear new ideas so please write a comment and share your 3pm munchie solution

Diet and Diabetes Prevention

Last week was Diabetes Awareness week in Australia and it reminded me of a conversation with a friend a few years ago. He was very worried about his Mum as she had just been diagnosed with diabetes but didn’t realise that this was a signal to him. With a family member having diabetes he is at higher risk, but he could reduce his risk by making changes to his eating and exercise habits.


It’s estimated that almost one in every 13 Australians has diabetes; half of these people don’t know they have it because they have never been diagnosed. In light of that, I thought I’d give a brief overview of diabetes and the role your diet can play in prevention.


What is diabetes?

Diabetes is a condition where someone is not able to control how much glucose (sugar) is in their blood. When we eat a meal, the glucose from the carbohydrates in the meal moves through ‘doors’ into our cells where it is used to make energy. These doors are opened by the hormone insulin.

Just like the remote for your car unlocks the car doors, so insulin opens the doors in your cells to allow glucose to move into all the cells of your body. When you have diabetes, you don’t make enough insulin or it doesn’t work properly: it’s as if the batteries of your remote control are running flat, and the doors won’t open. As a result, the glucose is stuck outside your cells and sits in your bloodstream causing high ‘blood glucose levels’.

Usually the body works hard to keep your blood glucose levels in a narrow range. Too low and your brain won’t work, too high over many years and it can lead to damage to kidneys, eyes and nerves, as well as increase your chance of a heart attack or stroke. So it is important that people who have diabetes are diagnosed and make changes to help their body control the blood glucose level.

There are two main types of diabetes: Type 1 and Type 2. People with type 1 diabetes do not produce any insulin and so need to have it injected regularly. This type of diabetes is genetic and usually diagnosed in childhood, but not always. At the moment there is no way to prevent or cure type 1 diabetes.

With type 2 diabetes, which is most common, your body either doesn’t produce enough insulin for your needs, or the insulin you produce does not work properly (flat batteries in the remote). Most people with type 2 diabetes can keep their blood glucose level under control by eating well and exercising regularly, or by taking medication.


Preventing type 2 diabetes – keep those batteries charged!

If you’re over 40 or if you have people in your family with diabetes, you are more likely than other people to develop diabetes. While there’s not much you can do about your age or your genes, there are other things in your control that can make you less likely to develop diabetes. These include your weight, your blood pressure, how often you exercise, and if you smoke. In fact, up to 60% of cases of type 2 diabetes could be prevented with healthy eating habits and regular exercise.


If you are at risk of developing type 2 diabetes you can delay or prevent this by:
  • Maintaining a healthy weight or if overweight, even a small weight loss will reduce your risk.
  • Being active for at least 30 minutes every day (walking, swimming, bike riding...)
  • Quitting smoking
  • Getting a health check every year
  • Eating well to give your insulin a chance!

Eating well to help prevent type 2 diabetes

Eating well and exercising to lose weight or stay a healthy weight are key to help delay or prevent type 2 diabetes. Try some of the healthy eating ideas below to help reduce your risk.

Five serves of fruit and two fruit each day can help with weight loss, lower blood pressure and help control your blood glucose levels.

Use unsaturated fats like canola margarine instead of butter and limit high fat foods

Increase the fibre in your diet slowly until you have 25 – 30 grams of fibre each day. Soluble fibre in fruit and oats slows down digestion so you don’t get lots of glucose in your blood all at once. That way the insulin can work slow and steady. Insoluble fibre, in cereals and the skin of fruit and vegetables, also helps insulin work more effectively though it is not yet known exactly how.

Use less salt in cooking and at the table as this will help to reduce high blood pressure, one of the risk factors of diabetes

Wholegrain foods can help make insulin more effective and also to help with weight loss; try to have half your grain foods as wholegrains, like wholegrain bread, breakfast cereal or crackers

Choose one low GI food with each meal. These foods break down more slowly so you don’t get lots of glucose in your blood all at once. (I’ll have a whole separate blog entry on GI soon!)

I have been focussing here on prevention of type 2 diabetes. If you have been recently diagnosed with diabetes or would like guidance on losing weight I strongly suggest you see an Accredited Practising Dietitian.

The squirrels are on to something....


In honour of my namesake I have decided to start my blog off talking about the health benefits of nuts. Research has shown they can reduce the risk heart disease and help weight control, all while being delicious!



Good for your heart
Nuts are high in fat, but it’s mostly the good fats – the ones that help reduce risk of heart disease. (I’ll tackle what are ‘good fats’ vs ‘bad fats’ in a future blog entry.)

Research suggests that eating a small handful of raw or dry roasted and unsalted nuts (30g) five times a week can help to lower blood cholesterol by ten percent. Why? The action of the good fats in nuts: polyunsaturated fats and monounsaturated fats.

Good for weight loss
As part of a healthy, balanced diet a small handful of nuts have also been found to help weight control. The protein and fibre in nuts slows down your digestion and so stops you from getting hungry again soon. The fats also help by sending signals that you are full. Eating an afternoon snack of nuts means you are less likely to get hungry and overeat later in the day.

Which nut?
Almonds, cashews, macadamias, Brazil nuts, pistachios, pine nuts and walnuts are all good choices; just remember to go for raw or roasted, unsalted nuts.

How much of a good thing?
My husband (The Canuck) came home a couple of weeks ago and announced that he was going to start eating 67 grams of nuts every day. He had read an article that claimed this was the magic amount needed to reduce risk of heart disease. Now, this is all well and good, but 67 grams of nuts is a lot of energy for an afternoon snack: almost the same amount of energy as a full meal!

So yes, you can have too much of a good thing. Due to the high fat content, nuts do pack a good punch in terms of calories. A small handful is about 30 grams, which is an appropriate amount of calories for a snack. Any more than this and you are adding extra calories to your daily intake and risk weight gain. So, remember to replace your afternoon chocolate bar or biscuit with a handful of nuts rather than adding nuts as an extra.

The Canuck is working on a handy 30 gram daily nut dispenser as we speak, stay tuned.
