The importance of proteins is inscribed in their name: in ancient Greek " prôtos « mean "first, essential". In effect, proteins assure the most part of cell functions.
proteins?
Alone source of nitrogen of the human body, proteins are necessary to life. They are constituted of amino acids (more than 50 in general) linked between them. Among these amino acids, there is 8 there that organism does not know how to fabricate that they call " essential amino acids ": it is therefore by our feeding that we must bring them to him.
Proteins serve for constructing and renewing the skin, bones, the muscles, the hair and the nails. It is as thanks to proteins as our body can defend itself against viruses and microbes. Necessary for numerous biological functions, they maintain our organism simply.
One is short of proteins the reduction of natural defences is therefore translated by a big tiredness, of problems of concentration and.
The children need proteins to assure a good growth, and it begins from the belly of their mother.
In what food to find proteins?
Proteins can be of animal or plant origin. They find animal proteins in:
- the meat
- the fish
- eggs
- crustacés
- dairy products
The animal proteins are the most full in amino acids, and particularly the egg which is the source of reference proteins, all essential amino acids being represented there.
For the plant proteins it is necessary to turn towards:
- pulses (dry beans, dry broad beans, mean pea, dry peas, lenses, kernel of soya, flageolets, broken peas)
- full grain
- soya and tofu
- the dry fruits
Can they go without meat?
Answer is yes. But certain amino acids are missing to the plant proteins. The vegetarians will therefore be able to compensate for this lack by eggs and dairy products. For the persons who do not use wildlife products, food supplementary benefits can be recommended.
What quantity of proteins in the plate?
Proteins provide 4 kcal / g of energy in organism. The nutritionists recommend, for an adult, to use 60 - 80 g a day, or for instance:
- a scallop of chicken of 120 g, a scoop of pasta of 250 g, a piece of cheese of 40 g and a yoghurt
- a back of cod of 120 g, two hard eggs, a nice edge of wholemeal bread and 100 g of dried walnuts
- a net of salmon of 120 g, a scoop of 250 g of lenses and 40 g of cheese
Hyper protéinés regimes?
A hyper protéiné regime is based on a strong consumption of proteins, with for objective a cast iron of grease without feeling the feeling of hunger (proteins being satiétogènes). Weight loss is more or less quick but this type of regime does not learn to eat balanced. Risk is therefore to take back the weight lost even to put on weight more! A hyper protéiné regime can be envisaged in stage of attack of a regime to be restricting its length in some days. You always make accompany with a specialist (dietician or nutritionist) to acquire the good reflexes for a feeding light and balanced in the daily.
Examples for scoops of 100 g:
Parmesan: 39.4 g of proteins
Braised beef: 32.1 g of proteins
Tuna to cook in the oven: 29.9 g of proteins
Turkey: 29.4 g of proteins
Semi-skimmed milk: 8,7 g of proteins
Emmenthal: 28.2 g of proteins
County: 28 g of proteins
Dry ham: 26.6 g of proteins
White of chicken: 26.2 g of proteins
Hacked steak cooks: 26 g of proteins
Tuna in its own juices: 24.5 g of proteins
Smoked salmon: 21.8 g of proteins
Pork roast: 21.1 g of proteins
Kernel of sunflower: 20.2 g of proteins
Steak of soya: 16.5 g of proteins
