Types of proteins that are present in food


Proteins - complex biochemical compounds madeof the amino acids in the formation of proteins providing the support for the person involved 22 amino acids.All kinds of protein compounds fall into two categories: one is called complete, others - defective proteins.It includes a full-fledged animal proteins contained in foods such as meat, fish, eggs, poultry, seafood and dairy products.Their use enables the body of eight amino acids, belonging to the indispensable, iethose which are produced in the body in insufficient quantities and which must be replenished from outside.

to defective proteins a
re of vegetable origin, in large quantities contained in legumes, nuts, seeds and cereals.Defective proteins do not contain the entire set of essential amino acids, so they must be consumed with a small amount of proteins.Nutritionists believe that the joint use of two types of proteins is more useful than separate their reception.It should also be taken into account when determining the daily diet, drawing on the daily needs of human proteins. Note that the person leading a physically active lifestyle or being under the influence of a stressful situation, needs more protein, in these cases the rate can be increased by almost half.

how much protein you need each day


Dietitians determined the dependence of the daily requirement of protein, based on age and weight, expressed as weight.It needs to be multiplied by the weight of the body to find out the nominal amount of protein, which your body has to get on a daily basis, to all the organs to function normally.

Thus, the age of 1-3 year, the weighting factor is 1.81, for 4-6 years it equals 1.5, 7-10 years - 1.21 in 11-14 - 0.99 15-18 years - 0.88 and after 19 years the weighting factor is equal to 0.79.If you are 30 years of age and your weight is 55 kg, the daily rate for the amount of protein you 55 * 0.79 = 43.45 grams of pure protein. need for proteins is almost constant throughout life, but after 60 years it begins to decline.

It turns out that for breakfast, lunch and dinner you should eat at least 15 grams of protein.But making up the menu, keep in mind that the protein needs change throughout the day.She would wake up the morning after and increases if you have experienced the intense exercise.Therefore adjust the consumption of foods with a high content of protein, depending on your daily routine and physical activity at different times of the day.
