The composition of the food groups


Foodstuffs are grouped according to their nutrient content. They often comprise several nutrients, but foodstuffs in the same group provide the same principal nutrient or nutrients.


BoissonsIt comes as no surprise that water is the main nutrient in drinks. It is a key element in all the body’s vital processes. Some kinds of water are rich in minerals, such as calcium and magnesium. Others contain less minerals.


Fruit légumeVegetables are rich in vitamins, particularly vitamin C, beta-carotene and some B vitamins. They also contain fibre and numerous minerals such as potassium. Fruit has a similar composition to vegetables. In general, fruit has a higher carbohydrate content.


viandeMeat is the group principally associated with a relatively high protein content. The food in this group also contains minerals and vitamins. Meat contains iron, fish contains iodine and egg yolks are rich in vitamin A. We also need to remember the fats provided by some kinds of meat or oily fish.


LaitDairy products primarily provide minerals. Milk is very rich in calcium. It also provides phosphorous which makes it easier for the body to digest calcium. The food in this group also contains proteins and greater or lesser amounts of lipids, depending on the product. The food in this group also provides vitamins. Almost all B vitamins are present in milk. Vitamin A is found in full-fat milk but not in skimmed milk. Finally, some dairy products are not classed under this group as they do not have the same nutritional properties. Butter and cream are included under fats.


CéréalesThe cereals group is primarily a source of starch, which is a complex carbohydrate. We should also be aware of the vegetable protein, B vitamin, mineral and fibre content. Dietary fibre, minerals and vitamins are present in larger quantities in unrefined products such as wholegrain cereals, pulses and potatoes.


SucreriesFood in the sweets or sugary products group basically contains simple carbohydrates, such as sucrose, glucose and fructose. The body easily absorbs sugar so it is a source of energy we can use quickly during intense physical effort. Some foodstuffs in this group also contain lipids. This is true for chocolate or toffees. The food in this group provides energy but no, or very few vitamins or minerals.


GraissesThe fats food group is characterised by food with a high fat content. Cream contains approximately 30 to 35% fat; butter and margarine over 80% and oil is 100% fat! However, fats also provide vitamins; butter and cream provide vitamin A and oils provide vitamin E.
