Diet can improve health. US scientists have found

The journal Science published a study conducted by members of the Pennington Center for Biomedical Research. According to the results, people who restrict themselves in calories experience less problems with immunity and metabolism than those who do not care about what they eat at all.

What did the scientists find out?


As part of the study, researchers at the Pennington Center for Biomedical Research in Louisiana, USA, studied immune function scores in humans who restricted their calorie intake by about 14% for two years, and in mice with a more severe restriction by 40%. Both examples showed improvements in the functioning of the immune system. In addition, in the case of mice, the average life expectancy has also increased.

Overall, dietary changes in all participants contributed to:

  • protection against inflammation;
  • decrease in the activation of inflammatory processes;
  • improving metabolic health.

What is the KBJU norm?

Marina: Reducing calories does not always improve metabolism and strengthen the immune system. This only happens if the diet remains balanced. It is important to observe the average daily allowance of calories, proteins, fats and carbohydrates (KBZhU), which must be consumed daily for the body to function properly. Protein foods provide the amino acids necessary for the formation of antibodies and other immune agents. Fats, in turn, are involved in the construction of immune cells, and carbohydrates provide energy for the functioning of the immune system. Proper use of the number of enzymes assigned to you will allow the body to work in the right rhythm, and you will feel great.

Why is overeating dangerous?


Excess calorie intake can lead to obesity, cardiovascular problems, diabetes, and high blood pressure. However, shortages also come with negative consequences. These include:

  • decrease in muscle mass;
  • anemia;
  • hair loss;
  • fragility of nails;
  • drowsiness.

How to calculate your calorie intake?


To determine how much you need to reduce or increase daily calories, you need to calculate the body mass index. This can be done in a fitness club with a testing specialist or using an online calculator. The average calorie intake for women leading an active lifestyle is 1800-2200 kcal, for men – 2400-2800 kcal.

Watch your diet, because the restructuring of metabolism and immunity against the background of calorie restriction allows you to stay healthy longer, and also increases life expectancy.
