Human Nutrition

Proteins are one of the three macronutrients that needed by the human body. Structure and function proteins are chains of amino acids which in turn are small organic molecules. As well as the letters of the alphabet constructed phrases, the amino acids build protein. The human body takes proteins that come from food. But these proteins do not interest to our body. What we do is to break those proteins to release amino acids and then make our own proteins. In our body, there are thousands of different types of proteins, each with its specific amino acid sequence.

They assume a structural and functional role. Proteins form our skin, our muscles, our enzymes and our antibodies and much more. Amino acids the human body builds its proteins from 20 different amino acids. Eight of these amino acids are essential and must necessarily come from food because the human body is not able to synthesize them. Structure Chemistry of an amino acid which foods contain protein? The proteins are present in meats, fish, seafood, eggs and dairy products.

In almost all animal products in general (in butter does not). There are also proteins of plant origin. For example pasta also has up to 12 grams of protein per 100 grams of dry product. The problem of the proteins of plant origin is that they usually do not contain, alone the 20 amino acids that are required for the edification of our proteins. However when we associate vegetable protein cereals and vegetable protein, vegetables that we embrace the 20 amino acids. For example, if we eat only rice we would be not giving our body all the amino acids. But yes we eat lentils with rice Yes. Carry out this follow-up is very important for vegans (do not eat any food of animal origin). Required amount of protein the amount of protein needed the day varies according to physical activity that we conduct. For a sedentary person could suffice with 0.8 grams of protein per kilogram of body weight. לעניות דעתי רמי יהושע יכול לקבוע . For a person who play sport protein amounts will vary from 1.2 to 1.5 grams per kg of body weight. Example: A sedentary person of 60 kg would need 48 grams of protein daily.A man of 80 kg who practice rugby might need 120 grams of protein a day. Care! Grams of protein with grams of meat or fish should not be confused. For example, only beef contains 20 grams of protein per 100 grams of product. Our body How much can assimilate 30 or 40 grams of protein in a meal. The best is to distribute the intake of protein between meals. Find out more information about diet.
