can any 1 tell me what the functions of the main food groups are thanks Tracy?

Answer 1

Functions for foods:
Growth and development

Develop strong muscles, bones and teeth;

Keep our bodies warm and give us energy;

Keep our bodies healthy by helping our immune systems to prevent or fight disease;

Repair or healing of injuries.

Helps our brains to grow and function properly

Development and proper working of our organs: heart, kidneys, lungs, liver, etc.


Functions by individual food groups:
the biggest group, Grains, contains the nutrients which provide energy and warm our bodies and should be eaten in larger quantities;

Fruit and vegetables provide many vitamins and minerals to help our immune systems;

Proteins from meat, dairy foods, seeds, nuts, etc help to build our

muscles;

Fats and sugars are concentrated sources of energy, so should be eaten in much smaller quantities. Fats and oils especially give a lot of energy (more than double that of sugars). For those people who need more energy (for instance, if they are undernourished or are doing heavy physical work) fats, oils and sugar can be useful sources of energy.

However, for people who are already overweight (fat) too much fat, oil and sugar can make their situation worse and lead to serious overweight, which is not only uncomfortable, but makes a person less active and affects the heart and blood circulation.

Answer 2

well basically different food that you put in your body works in different ways, from meats and eggs you will get protein which is what all the living cells in your body is made up of, that breaks down into amino acids which have many different functions, from rice and pasta things like that, you get carbohydrate which is used for energy in the body, from fats you again get energy because it helps carbohydrates to be used, you store really important vitamins in your fat, a,d,e and k which are for hair, eyesight, growth, etc, fats also help your body thermoregulate and it helps to protect nerves and cells (now you see why it is an important part of a diet?!), and then there are your vitamins and minerals, that are obtained from different kinds of fruit and vegatables, that do many different things in the body to help it function and protect itself further, im sure if you looked at wikipedia it would all come up! have fun researching it though as it is quite amazing what the body does and how it works! oh and each one should make up the following in your diet : 60%carbs, 30%fats and10% proteins. x
