Basic dietary rules: food balance

The daily balance
In a nutshell, to achieve food balance, you need to consume every day:
- 5 portions of fruit and vegetables, between about 400 and 600 g, no matter in what form (fresh, jam, cooked, fruit juice ...)
- 3 dairy products (cheese, milk, yogurt)
- 1 or 2 times fish, meat or eggs
- 1 or 2 "portions" (one tablespoon) of fats
- 3 servings of starchy foods and / or bread
An ideal meal therefore consists of a raw and / or cooked side dish, a source of protein (meat, fish, eggs), a portion of flour and / or bread, a dairy product, a fresh or cooked fruit.
To get your fill of vitamins and minerals, it's important to vary your foods and limit processed products, which are low in micronutrients but high in hidden fats and sugars.

In detail
Each food has its own nutritional composition. It is made up of energy-rich macronutrients (proteins, fats and sugars), micronutrients (vitamins and minerals), fiber and water. The set of foods consumed constitutes the diet.
