Notes
Reading text and
vocabulary task.
Eating the right
things
Trying
to eat more of the right things does not mean 'going on a diet',
especially not a quick-fix
diet. True, you may lose weight, but it could well be only temporary
and you could be less healthy as some diets don't provide all the
things you need.
There's
no such thing as a single superfood which contains every nutrient
you'll
need, so only by eating a varied
diet will you get all you need to stay healthy. There are five main
food groups and you should eat a good balance of each of them.
Fruit
and vegetables
Fresh
fruit and vegetables, frozen, canned, and dried fruit &
vegetables all count. You should try to eat at least five portions of
fruit & veg each day. Juice also counts as a portion, but however
much you drink in a day it will only count as one portion. This is
because juice doesn't contain as much fibre
as whole fruit.
Bread,
potatoes and cereals (including noodles, pasta and rice)
Foods
like these should make up half your plate. They are your body's main
source of energy. Surprisingly, potatoes also contain vitamin
C
and absolutely no fat.
Lean
meat, fish, poultry, eggs, nuts, beans
All
of these provide protein,
which helps your body rebuild itself (repairing damaged muscles,
hair, nails etc). If you're vegetarian or vegan
you're not going to eat the meat & fish... but eating soya
also does this and there are smaller amounts in grains and dairy
products.
Milk
and dairy products
These
are a source of calcium,
which strengthens your bones and teeth and helps your muscles and
nerves function properly. The best products are those having lower
fat. A pint of milk a day is enough to ensure you're getting the
recommended
amount of calcium.
Foods
containing fat and sugar
Fat
is a great energy source, but fatty foods don't contain very many
nutrients. Just one gram of fat contains about nine calories
so unless you take a lot of exercise your body will retain the fat
and you'll put on weight. But don't avoid eating fat altogether -
your body needs energy and in smaller doses fat is an important part
of healthy eating.
