'BASIC
FOOD GROUPS'
Food can be
split into five basic groups, plus drinks. The key is balancing
the amount of each in your diet to leave you feeling healthy and
full of energy. Its easy to enjoy eating healthily once you
know how.

FRUIT
AND VEGETABLES
What are they?
This food group includes all fresh fruit and vegetables, as
well as frozen and canned produce, juices and dried fruit.
Why do we
need them?
All research seems to be pointing in the same direction. Eating
more fruit and veg will give you big health benefits. Not only for
their contribution to your needs for fibre, vitamins and minerals,
but in helping to prevent heart disease and cancer. Fibre keeps
the digestive system working by providing the bulk for food to move
through the system.
The vitamins
in fruit and veg are easily broken down by cooking, so for maximum
nutrition keep cooking times to a minimum - boil briefly until al
dente or try steaming, stir-frying or eating them raw as a snack
or in salads.
How much
should we eat?
The government recommends that we eat at least five portions of
a variety of fruit and vegetables every day. A portion can be one
piece of fruit, one glass of fruit juice or one serving of vegetables.
And remember, if you smoke, you need more vitamin C than a non-smoker,
so it's even more important to aim for five.
CEREALS
AND GRAINS
What are they?
All sorts of bread, rice, chapatis, potatoes, yam, sweet potatoes,
breakfast cereals, pasta, noodles, oats, couscous, bulgar wheat
and polenta. They are known as starchy foods.
Why do we
need them?
These are fuel foods. Essentially, they provide us with the energy
we need not only for physical activity but also for all our body's
day-to-day functions. They do this by supplying us with carbohydrates.
Carbohydrates can either be simple or complex depending on their
basic structure. Sugars are simple carbohydrates whereas starches
are complex carbohydrates, a better source of carbohydrate for health.
The body converts these carbohydrates into glucose and glycogen.
Glucose is used in the blood to deliver immediate energy whereas
glycogen is stored in the liver for longer-term, sustained activity.
Complex carbohydrates
can either be processed, as in white bread, or unprocessed, as in
wholemeal bread. While both types provide us with energy, the unprocessed,
wholegrain forms have more fibre which helps maintain a healthy
digestive system and contains more B vitamins.
How much
should we eat?
The government recommends that 50 per cent of our daily calories
should come from these carbohydrate sources, so try basing your
meals around them.
FATS
AND SUGARS
What are they?
Butter, margarine, oils, cream, sugar, syrups and foods containing
fats and sugars such as cakes, biscuits, crisps, sweets, chocolate,
puddings, cream, ice cream, mayonnaise and deep-fried foods.
Why do we
need them?
Lots of the treats we all love are fatty and sugary foods, but do
they have a place in a healthy diet? While it's OK to eat these
foods in moderation, it's best to keep them to a minimum. Foods
in this group are concentrated sources of calories, so no good if
you're watching your weight, and sweets and snacks are packed with
the health baddies - fats (mainly saturated), sugar and salt.
Fats provide
us with essential fatty acids which are vital for proper nerve function.
Fish oils are particularly good for this. Limit the amount of fat
you use in cooking and on bread and choose those that are rich in
polyunsaturates or monounsaturates, such as sunflower or olive oil.
How much
should we eat?
Try to limit yourself to 2 portions of sweet, fatty foods a day.
If you're overweight, cutting back on these types of foods is one
of the easiest ways to cut calories without losing nutrients.
MEATS
AND PROTEIN
What are they?
Red meat such as lamb, beef and pork, poultry such as chicken
and turkey, game including grouse, pheasant and duck, fish and eggs,
as well as vegetarian alternatives such as nuts, beans, peas, lentils,
tofu and other soya-based products.
Why do we
need them?
These foods are important sources of protein, iron and zinc. Proteins
are the building blocks of our body which maintain healthy tissues
and repair any damage. Proteins are made up of amino acids, most
importantly the essential amino acids which cannot be made inside
the body and so have to come from the food you eat. If you are vegetarian
or vegan it is advisable to make sure you eat a variety of different
protein sources to ensure that you get a full complement of the
essential amino acids.
How much
should we eat?
Most people only need to eat moderate amounts to get the protein
they need - health professionals recommend that 10-15 per cent of
energy in our diet should come from proteins. Government recommendations
to prevent cancer advise eating less red meat (no more than one
portion a day) and to eat a mixture of foods from this group. Fish
is recommended at least twice a week - especially oily fish, such
as herring, mackerel or sardines, for their omega-3 fatty acids
which help reduce the risk of a heart attack or stroke.
DRINKS
What are they?
Drinks include water, fruit juices, canned drinks, tea, coffee.
Why do we
need them?
The human body is mostly water, so drinks are very important to
keep our fluid balance correct. Water is the basis for all our body
functions and even slight dehydration can have a huge effect on
how we feel and how effectively we work. Its worth knowing
that tea and coffee also contain caffeine which acts as a stimulant
raising blood pressure and making the heart beat faster. While caffeine
can act as a great pick-me-up, in higher doses it can limit vitamin
and mineral absorption and actually have a negative effect on our
energy levels. We are also advised to keep an eye on the amount
of alcohol we drink each day. While drinking alcohol can be a relaxing
way to socialise, drinking too much on a regular basis can be damaging
so try not to go overboard!
How much
do we need?
The government recommends we drink about two litres of water every
day. This may seem like a lot but this includes the water in hot
drinks, soft drinks and fruit juices.
For drinks that
contain caffeine, health professionals suggest limiting our intake
to 2-3 cups a day.
In terms of
alcohol, the government recommends no more than 2-3 units a day
for women and 3-4 units a day for men. A unit is equivalent to a
glass of wine, half a pint of beer or one pub measure of sprits.
DAIRY
What are they?
Dairy products include milk, yoghurt and cheese.
Why do we
need them?
The most important constituent of dairy produce is calcium, a mineral
thats essential for healthy teeth and bones. Its important
not only for children to have enough calcium for their teeth and
bones to grow, but also for adults to prevent osteoporosis in later
life. If you cant eat dairy products, either because youre
vegan or lactose intolerant, you can get your daily dose of calcium
from other sources such as soya milk enriched with calcium, green
leafy vegetables such as spinach and dried apricots or figs.
How much
should we eat?
The Department of Health recommends that we need 700mg of calcium
a day. In food terms this is equivalent to a pint of milk, two small
pots of yoghurt or 80g of hard cheese.
