Eating a balanced diet

The key to good health is a balanced diet...but it can sometimes be hard to stick to! 

Day to day
To get a balanced diet, you need to eat the following every day:
-5 portions of fruit and vegetables (about 400 to 600g) in any form (fresh, cooked, juiced, puréed)
-3 portions of dairy produce (cheese, milk, yoghurts)
-1-2 pieces of fish, meat or eggs
-1-2 tablespoons or knobs of fat (oil, butter)
-3 portions of bread

According to the above, the ideal meal consists of 1 raw vegetable and/or 1 cooked vegetable, 1 source of protein (meat, fish or egg), 1 portion of bread, 1 portion of dairy, and 1 fresh or cooked piece of fruit.
To make sure you get the right vitamins and minerals, it’s important to vary the foods you eat and to limit your intake of processed foods, which are low in nutritional value but high in fat and hidden sugar.

Macronutrients

	Roles	Requirements	Sources
Protein 1g = 3 Kcal	The body's building blocks. Helps organs and muscles to function and develop	1g per kilo of body weight every day (e.g. 60g if you weigh 60kg). 15% of energy intake	Meat, fish, eggs, dairy produce (animal protein), cereals, nuts and seeds (vegetable protein)
Carbohydrate 1g = 4 Kcal	Provides the fuel that muscles and organs (including the brain) need to function	Around 55% of energy intake, preferably as starch	Cereals, nuts and seeds, starchy foods, dairy produce (except cheese), fruits, confectionery
Fat 1g = 3 Kcal	Makes up cells' energy reserves and protects the vital organs	Around 30% of energy intake, preferebly in the form of unsaturated fat	Butter, meat, fish, eggs, dairy products, oils, margarine, oil-producing fruits and lots of manufactured foods

Fibre
Also known as roughage, fibre is made up of non-digestible plant components. It’s found in both the walls of vegetable cells (cellulose, pectin) and inside vegetable cells (gum, mucilage). Fibre slows down the emptying of the stomach after a meal, giving you a full feeling. It slows down carbohydrate absorption in the stomach, regulates the passage of food through the intestines and helps prevent constipation. It also reduces cholesterol and the risk of colon cancer.
You need 25 to 30g per day and you can get it from fresh and dried fruit, vegetables, grains and cereals (especially wholegrain).
