Animal meat or fish proteins have the advantage of being complete, very comparable. Pay attention to choose its sources in order to avoid unnecessarily overload fat. Plant sources must be combined to become complete.
The sources of protein can be quite numerous, but there are, at our food, two major sources: animal protein and vegetable protein.
The Animal protein is the best source of protein. These are complete proteins, so no problem for assimilation and especially their concentration is high, around 20% in most meats and fish. Some pieces of meat with a disability: the fat content. For meat red, the fat content may vary from 5% to 25%, the maximum nearly as much as the protein content. More than half the calories of a piece of meat thus derived lipids. These fats, besides being in large quantities, are in saturated form. This form of fat is, however, essential to the proper functioning of our body, but excess intake can be harmful especially if the source of the meat is derived from non-organic farming. In fact, fat is a place where all toxic, from food or medicines, are stored! For white meat (chicken, turkey, rabbit…), saturated fat content ranges from 5% to 10%. Fatty fish can replace meat fat
because they contain unsaturated fats and are rich in omega 3 provided that cooking is not aggressive, omega-3 are, unfortunately, vulnerable to heat. They have also the same protein content than meat. If you want to reduce the amount of lipid, as in hypocaloric diet, it is interesting to remove visible fat from meat and do not eat the cooking juices. For poultry, simply do not eat the skin, which is rich in fat.
Plant proteins generally have a bad reputation, athletes do not give them a little credit. However, achieving good eating associations, these proteins can be interesting. The amino acids whether of animal or vegetable origin are the same, only their amino acid concentration is different. It is for this reason that they are incomplete. This drawback is easily circumvented by splitting food sources, so by having a balanced diet. Note that soy is the only plant protein that could be set to complete but the amino acid content, however, far up the contributions of animal protein. In addition, soya is rich in estrogen, a female hormone. Men should therefore not be abused. The plant proteins are rich in fiber, vitamins / minerals and carbohydrates. They also have an advantage over the meat; they contain no fat, and calorie intake is much lower, but they often suffer from a major carbohydrate intake, which can be detrimental to the plan when seeks to reduce sugars.
