At the beginning of the 20th century, it was found that many people in some areas of Bulgaria lived a long life, which was related to the widespread consumption of yogurt. Yogurt has the following benefits to human health.
(1) Lactobacillus grows and reproduces in fresh milk at suitable temperature, and decomposes lactose in milk into lactic acid. Lactic acid can change the neutral or alkaline environment in the intestine into acidity, thus destroying and inhibiting the growth and reproduction of spoilage bacteria in the intestine. Protect the human body from or reduce the harm of toxic substances. This is because the spoilage bacteria in the intestine can move a lot in neutral or weakly alkaline environment, which not only decomposes protein in the intestine, but also produces some toxic substances, such as indole, phenol and fecal odor. Affect your health.
(2) Yogurt can promote gastric peristalsis, stimulate gastric acid secretion, enhance the digestive ability of gastrointestinal tract and improve the metabolism of the body.
(3) In the process of growth and development, lactic acid bacteria can produce an antibiotic, which can inhibit and destroy the growth of many pathogenic bacteria, such as mycobacterium tuberculosis. Therefore, it has preventive and adjuvant therapeutic effects on some diseases.
(4) Lactic acid can increase the number of beneficial bacteria in the intestine and inhibit spoilage bacteria, so it can prevent toxic substances produced by decomposing protein by spoilage bacteria from accumulating in the body, thus preventing the occurrence of some cancers.
(5) Free amino acids and peptides in milk increased after lactic acid bacteria fermentation. The analysis shows that the content of free amino acids is about four times that of milk, and the content of essential amino acids is about four times that of milk.
(6) After milk is treated by lactic acid bacteria, its fat structure becomes easier to be digested and absorbed by human body. Among them, calcium becomes calcium lactate, which not only helps yogurt to form clots, but also makes calcium easily absorbed by human body, which is of great benefit to the prevention and treatment of osteoporosis in the elderly.
(7) The contents of vitamins A, B 1, B2 and C in yogurt are similar to those in milk, but the content of folic acid is more than 1 times higher than that in milk, and the content of choline is obviously increased, which has obvious effects on preventing fat oxidation and high cholesterol concentration in the body.
(8) Elderly people are prone to constipation due to decreased metabolic function, atrophy of colon and rectum, and decreased secretion of intestinal mucus. Yogurt has a laxative effect, so it has a preventive effect on senile constipation. In addition, yogurt is nutritious and easy to digest and absorb, so it is an ideal healthy food for the elderly.
To sum up, yogurt can make people healthy and live longer, and long-term enjoyment can prolong life.
