Everyone knows that the calorie content of foods is calculated from the energy released during the digestion of food. At the same time, minerals and vitamins are not high-calorie. The main nutritional ingredients that affect the energy value of meals are proteins, fats and carbohydrates. Let's talk about this in more detail, and in particular about what is the calorie content of proteins, what the body needs them for, and how they should be consumed.

He althy Protein Food

Usually, when calculating calories, most look at the fats and carbohydrates found in food. But the calorie content of protein foods, as a rule, is ignored. Of course, these questions are the most relevant for those people who want to quickly get rid of extra pounds.

At the same time, proteins are very important for the normal functioning of the body. They are involved in the structure of tissues, essential enzymes and hormones. But of course it's notThis means that they should be consumed in excess. Such a diet will also lead to an excess of calories, and with it, to excess fat mass.

Calories

The most high-calorie, of course, are fats. One gram of substances they have is equal to nine kilocalories. At the same time, there are more than half as many calories in proteins and carbohydrates: there are only four kilocalories per gram. It turns out that when a protein gram is broken down, about four kilocalories are released. Therefore, people who want to regulate their weight should definitely find out the optimal level of diet and study the calorie content of proteins, as well as fats and carbohydrates.

According to average estimates, it is believed that a person should consume from two to three thousand kilocalories per day. In fact, this indicator should be individual. It depends on various factors, such as body weight, activity level, age and occupation. If you want to lose weight, you should not pay attention to the calorie content of proteins. The reduction should be made by limiting the intake of carbohydrates and fats.

How much protein does a person need?

Every day the human body requires up to one hundred grams of protein. If we consider plant products, then most of them are found in soybeans: per hundred grams - it contains approximately thirty grams of protein. Peas and beans are also rich in them. It can be found in large quantities in some products of animal origin, among which eggs, sea fish,bird, fish caviar. They also have up to thirty grams of protein per hundred grams.

Chicken egg

Often speaking of proteins, they mean directly part of a chicken egg. This product is eaten raw, boiled, and fried. Some people, on a diet, separate it from the yolk and use it separately. The omelette then turns out to be very useful and tasty. Let's study how many calories are in this product.

Chicken protein nutritional value

99% of this species is able to be absorbed by the body. Therefore, he alone can fully cover the daily norm for a person. A chicken egg weighs about seventy grams on average. At the same time, the protein in it is fifty grams. Therefore, speaking of one hundred grams, we mean the parts separated from two eggs. Their calorie content is only 45 kilocalories. It turns out that eating an egg without a yolk, you can not worry about your figure. But it does not contain carbohydrates and fats at all. Therefore, this product is extremely rich in proteins and is very easy to digest. Thus, these biologically active substances, taken from two or three eggs, fully cover the daily requirement of the body.

In addition, the protein includes glucose and enzymes that allow you to quickly digest food, preventing the intestines from becoming clogged with toxins. It also contains vitamins B, A, D. Even if there are no meat products in the diet, the substance will fully provide the necessary niacin, the absence of which interferes with the formationsex hormones and the proper functioning of the brain. Thus, the complete rejection of animal food can even lead to the loss of reproductive function.

The low calorie content of protein has made the product extremely popular in cooking: it is included in all types of pastries and sweet cream. Salads with its addition become more useful. At the same time, yolks can find a lot of useful applications. For example, they are used to make crumbly cookies. In addition, there are many beauty recipes using this part of the egg. Many face and hair masks are made from it, either alone or with other ingredients.

Boiled and fried protein

Calorie content of 1 g of protein, of course, depends on the method of its preparation. In order for all useful properties to be preserved, the heat treatment method must also be taken into account. So, one hundred grams of boiled protein contains from forty to forty-four kilocalories. At the same time, there will be more of it in fried form, since other fats also take part in this process. So, a whole fried egg per hundred grams will be as much as 360 kilocalories.

Calorie table of products and ready meals

So, the average daily requirement for a person is 2500 kilocalories. But, as mentioned earlier, these indicators are very individual. So, for women under 25 years old, leading a sedentary lifestyle, this rate is 2000 kilocalories. From 26 to 50 years old - and even less, about 1800. However, if they lead an active lifestyle, then the norm increases by 200 kilocaloriesdaily.

For men who lead a sedentary lifestyle, under the age of 30, the norm per day is 2400 kilocalories. And for those who are older, from 31 to 50 years old - 2200. But if their lifestyle is active, then up to thirty years old they need 3000 kilocalories, and up to 50 years old - from 2800 to 3000.

For clarity, the following table of calorie content of products and ready meals is given.

The daily protein requirement is 100 grams, which corresponds to 410 kilocalories. But fats should be consumed less per day, only 60 grams. But, in terms of kilocalories, it will be equal to 560. Fats are necessary for the body. For example, Omega 3s are fatty acids. A good balanced diet is a daily allowance of 30 grams of animal and 30 grams of vegetable fats. Carbohydrates per day is enough 370 grams. In terms of kilocalories, this turns out to be 1530. Thus, the body needs them the most. And it's natural. After all, it is carbohydrates that provide the body with the necessary energy.

Conclusion

If necessary, the body will be able to adapt to a smaller amount of protein consumed daily. However, it is unreasonable to subject it to such loads. The amount of protein consumed, which is needed every day, should not be reduced. Weight loss should come from carbohydrates and fats. Then fat deposits simply have nowhere to come from.

Proteins are involved in almost all processes. Their deficiency has a negativeimpact on the body. This leads to changes in the liver, deterioration in the absorption of substances, hormonal levels, disruption of the endocrine glands. Even deaths have been recorded when low-calorie diets were followed for a long time. Eating protein foods is very important for maintaining human he alth. For Russians, this issue is especially relevant, since, judging by the studies, we usually do not have enough of this biologically active substance in our diet.
