"How to eat more wholegrains and
enjoy them"
Some ideas on informing and persuading the Australian
public that wholegrains are good for us, and how easily they can be incorporated
into our diet.
What are grains and grain foods?
Research shows that many people don’t know what grains
and grain foods are.
Examples of grains:
- Rye
- Wheat
- Rice
- Barley
- Corn
- Oats
Examples of foods made from grains:
- Crumpets
- Muffins
- Cakes
- Breads
- Breakfast Cereals
- Cous Cous
- Pizza
- Biscuits
- Pasta
- Pancakes
But not all of these foods will provide you with the more
nutritious ‘wholegrains’. It depends on how much they have been processed.
70% of Australians can’t correctly identify wholegrains. 30% of people
interviewed believed white rice is a wholegrain and 18% thought white bread is a
wholegrain food.
Grains – how much should I eat?
Most Australians recently surveyed (Go Grains, March 1999)
thought that they were already eating ‘enough’ grain products, yet they fell
short of the amounts recommended by nutritionists. Reasons for not eating more
grains were that people didn’t think they were as healthy and fruits and
vegetables, breads were seen as ‘fattening’ and breakfast cereals were often
thought to contain too much sugar.
The recommended daily intake of grains is 5-12 servings,
depending on your activity level. One serve could be:
- 1 slice of bread
- 1 bread roll
- 4-5 crispbreads
- 1 English muffin or scone
- 1/2 cup cooked rice or corn meal
- 1 cup of cooked pasta or noodles
- 1 cup of breakfast cereal
- 1/2 cup of cooked porridge
- 1/3 cup of muesli
CSIRO, Food & Nutrition Plan, 1992.
Nutritionists generally agree that in particular, people
need to eat more wholegrains like wholemeal and wholegrain bread, high fibre
cereal, brown rice and wholemeal pasta. You should include at least 3 servings
of wholegrain foods each day. “3 are key”.
What is a wholegrain?
A ‘wholegrain’ contains the entire edible parts of a
natural grain kernel.
- Bran (outer layer) accounting for 14-16% of wheat, 5-6%
of corn
- Endosperm (middle layer) making up 61-80& of all
wholegrains
- Germ (inner layer) accounting for 2-3% of wheat, 10-12%
of corn
What are wholegrain foods?
There is no legal definition for ‘wholegrain foods’ in
Australia but these can generally be considered as those made by using mostly
wholegrains or wholegrain ingredients, rather than refined grains or refined
ingredients.
In the USA, a new health claim was recently permitted on
food labels enabling manufacturers to state that wholegrains can help reduce the
risk of heart disease. For products to be considered as ‘wholegrains’ by the
Food and Drug Administration, they need to contain at least 51% of their content
as wholegrains.
What are the protective nutrients in wholegrains?
There are many important nutrients in wholegrains
including:
- Protein
- Carbohydrates
- Dietary Fibre
- Resistant Starch
- B Vitamins including niacin, thiamin, riboflavin,
pyridoxine, pantothenic acid, folate
- Minerals including iron, zinc, copper, magnesium,
manganese
- Phytosterols - b -sitosterols
- Antioxidants including vitamin E and selenium
- Phytochemicals including phytoestrogens, flavonoids,
phytic acid, phenolic acid, protease inhibitors, saponins
Additionally, wholegrains are low in fat and cholesterol
free.
Some of these nutrients found in wholegrains are added to
refined grain products. But it is impossible to enrich refined products with the
complex mix of phytochemicals that are lost upon refining.
Effects of refining
Because nutrients are not distributed evenly within a
wholegrain, refining results in the loss of many vitamins, minerals and
bioactive substances (called phytochemicals) found within or close to the germ
or bran layers. Most of these are not replaced by fortification of refined
products.
Refining can remove more than 2 dozen essential nutrients,
dietary fibre and phytochemicals, many of which have established roles in
helping to protect us against heart disease and other degenerative diseases.
Look at the example of wholemeal and white flour. When
white flour is made, 66% of the dietary fibre, 92% of the selenium, 62% of the
folate and up to 99.8% of the natural phenolics (phytochemicals) are lost. Some
manufacturers are adding back certain vitamins that are lost in refining, like
folate, thiamin and Vitamin E, but only to some products.

Where do we get our wholegrains from?
Most people get their wholegrains by eating breads and
breakfast cereals. But a look at the top 10 selling brands in Australia shows
that many of these do not supply wholegrains.

How to check food labels for wholegrains?
- Look for symbols or logos suggesting the product
contains wholegrains; these are designed by individual manufacturers so will
vary from one brand to another.
- Often the manufacturer will make health promoting
claims on the packet and often there is a grain element in the name of the
product.
- You can also check the ingredient list. Look for words
like “wholegrain” and “wholemeal”.
Easy ways to incorporate wholegrains into your diet
- Choose wholegrain or wholemeal breads, wholegrain
English muffins and wholegrain crackers.
- Use wholemeal spaghetti, macaroni, and other types of
pasta.
- Eat wholegrain breakfast cereals.
- Make a muesli with a mixture of rolled grains, such as
oats, rye and triticale.
- Use brown rice in place of white rice whenever
possible.
- Add cooked brown rice when making burgers.
- Make tabouli salad using bulghar wheat.
- Add unpearled barley to soups and casseroles.
- Add wholegrains to salads, eg brown rice or corn.
- Use wholemeal flour in baking.
- Add oats to muffins, slices and cakes.
- Add blended corn kernels to savoury pancake batter.
- Try a pilaf made from different grains, such as millet.
- Use corn-on-the-cob and popcorn as snack foods.
There are many ready-to-eat wholegrain foods to choose
from in Australian supermarkets. Wholegrain foods don’t have to be more
expensive or take longer to prepare. They can also taste great!
Cooking wholegrains from scratch!
Here is one of my favourite wholegrain recipes, to show
you just how easy it is to cook wholegrains from scratch. Investing in a
pressure cooker will reduce the cooking time by 75% so I highly recommend it.
Bon appetite!
|
Crunchy Wheat with Tropical Fruits
1 cup uncooked whole wheat
5 cups of water
¼ cup pecans, chopped
2 tablespoons pine nuts
½ cup currants
¼ cup dried mango, diced
¼ cup dried paw paw, diced
2 tablespoons honey
- Rinse the whole wheat and cook covered with 5
cups of water until it is tender. This will take approximately 1 hour
on a conventional stove or 15 minutes in a pressure cooker.
- Prepare the other ingredients while wheat is
cooking: chop pecans and dried fruit.
- Drain most of the water from the cooked wheat
using a sieve, but still leave it moist and add to a large mixing
bowl.
- Add remaining ingredients and mix well so that
the honey is distributed and coats all the ingredients.
- Serve in a breakfast bowl and enjoy! Makes 4
generous servings. Keeps well in the fridge for up to a week.
Serves 4
This dish makes a super breakfast and has real
crunch to give your jaw a healthy workout. You can also serve it for
dessert with a dollop of your favourite yoghurt or as a snack.
