Proteins: The origin of proteins. Proteins of animal and vegetable origin

The food we eat is a treasure trovenecessary for the proper functioning of organs and tissues of biologically active substances. One of these useful additives are proteins. The origin of proteins and their quantity in various products are suggested to be considered below. Also at the end of the article proposed a protein diet for men and women.

Proteins, the origin of proteins

Proteins perform the main plastic function in the body. Thanks to them, the construction of growing and reproduction of collapsing tissues occurs.

The composition of proteins includes amino acids. Some of our bodies are able to produce by themselves, they are called replaceable, while others are not, that is, they are irreplaceable.

Depending on the food consumed there are proteins.animal and vegetable origin. There is also a special drug - protein, which is sold in pharmacies and health and sports nutrition stores.

Difference depending on origin

How to understand what proteins to eat? The origin of proteins affects the amount of nutrients obtained. But their difference lies not only in this.

There is information that the main differencebetween proteins of animal and plant origin are their amino acid profiles. Animal proteins, of course, are much more similar to ours, thus being absorbed more easily and faster than vegetable ones. Vegetable proteins are somewhat compromised by their limited content of amino acids.

According to the findings of the Harvard Schoolpublic health (GSHO), animal protein has a balanced combination of all amino acids, so it is called a complete protein, the vegetable protein is incomplete.

Есть множество дополнительных факторов, которые should be considered when analyzing proteins in the diet. GSHOZ states: "Animal protein and vegetable protein probably have the same effects on health."

The researchers at this school found that sixounces of servings of roast steak and salmon provide 38 and 34 grams of protein, respectively. But at that time, the steak also contains 44 grams of fat, and salmon contains 18 grams. A cooked cup of lentils, meanwhile, offers less protein (only 18 grams), but it also contains less than one gram of fat.

But it is indisputable that plant proteins have their advantages:

• they oxidize our blood less because of the greater amount of minerals in them;
• contain less impurities;
• contain less fat;
• there is no bad cholesterol;
• while taking plant foods, there is less stress on the liver and kidneys;
• easy to digest.

Animal Protein

Senior Food and Food Officerthe agricultural organization Ellen Maulhoff (USA) says that especially in developing countries, fish and other meats, as well as eggs and milk, are an important source of high quality protein and trace elements that are harder to obtain from plants. Other proteins of animal origin that have a high value are water-soluble by-products of the cheese making process.

Vegetable proteins

Soy products are one of the best options in terms of vegetable proteins.

In a study by the Harvard Public SchoolHealth in 2007 states that plant sources of protein such as beans, nuts and whole grains, offer a greater range of nutrients: healthy fibers, vitamins and minerals.

How much protein is in buckwheat, other cereals and flour products

Do you like porridge? Or do you prefer bread to any dish?Then you should know how much protein is in buckwheat, rice, pasta, other cereals and flour products. We suggest to get acquainted with the tables below.

Human need for protein

Nutrition is achieved whenThe diet includes various foods, primarily of plant origin (vegetables, cereals, legumes, fruits, wild edible plants), as well as animals (meat and poultry, eggs, various dairy products, sea gifts). The amount of animal protein should be about 55% of their total content in the diet.

So how much protein do we need? Experts recommend taking from 0.8 to 1 gram of protein per kilogram of our weight. But the total amount should not be less than 40 grams.

Женщинам необходимо начинать употреблять большее the amount of protein in the second half of pregnancy and continue while breastfeeding. You should also increase the dose of protein with frequent stress and illness.

Protein deficiency

Protein deficiency does not occur suddenly. The disease can develop over the years, starting from childhood. And the disease can be transmitted to the children of the patient.

Symptoms of a lack of protein in the body:

1. excessive irritability;
2. apathy;
3. prostration;
4. hypotension;
5. muscle degeneration;
6. swelling that mask weight loss;
7. loss of hair its elasticity and fading color.

Excess protein in the body

Excess protein tends to transform to fat and glucose. As a result, a person's health deteriorates and his performance decreases.

Symptoms of excess protein:

1. deterioration of appetite;
2. increased excitability of the central nervous system;
3. an increase in the amount of adipose tissue in the liver;
4. deterioration of the cardiovascular system, liver and kidneys;
5. brittle bones;
6. appearance of gout.

Protein diet

We offer you to get acquainted with examples of the protein diet menu separately for men and women, based on their average weight.

Sample menu for male vegetarians with a calculation of about 63 grams of protein per day

Sample menu for female vegetarians with a calculation of about 52 grams of protein per day

Note that this diet does notdesigned for everyday meals. This menu without harm to health can be used during fasting days. It is also necessary to adhere to specific recommendations for men and women.
