Yogurt is a kind of dairy product which takes milk as raw material, adds beneficial bacteria (starter) to pasteurized milk, ferments, and then cools and fills. At present, most yogurt products on the market are solidified, stirred and fruity with various juices and jams. Yogurt not only retains all the advantages of milk, but also exerts its advantages and avoids its weaknesses in some aspects, making it more suitable for human nutrition and health care products.
During the fermentation of yogurt, about 20% of sugar and protein in milk are hydrolyzed into small molecules (such as galactose and lactic acid, small peptide chains and amino acids), and the fat content in milk is generally 3%-5%. After fermentation, the fatty acids in milk can be increased by 2 times compared with raw milk. These changes make yogurt easier to digest and absorb, and the utilization rate of various nutrients can also be improved. Yogurt is fermented from pure milk. Lactic acid bacteria can not only retain all the nutrients of fresh milk, but also produce various vitamins necessary for human nutrition, such as VB 1, VB2, VB6, VB 12, etc.
The function of yogurt:
First, it can decompose lactose and protein in milk, which is easier to be digested and absorbed by human body.
Second, yogurt can promote the secretion of gastric juice, increase appetite and promote and strengthen digestion.
Third, lactic acid bacteria can reduce the production of some carcinogens, thus having anti-cancer effect.
Fourth, it can inhibit the reproduction of spoilage bacteria in the intestine and weaken the toxins produced by spoilage bacteria in the intestine.
Fifth, it has the function of lowering cholesterol, especially suitable for people with hyperlipidemia.
Sixthly, generally speaking, patients take or inject a lot of antibiotics to treat diseases or prevent infection, which makes the intestinal flora change greatly, and even some beneficial intestinal bacteria are suppressed or killed, resulting in flora imbalance. Yogurt contains a lot of lactic acid bacteria. Drinking 0.25-0.5 kg per day can maintain the normal intestinal flora balance and adjust the beneficial intestinal flora to a normal level. Therefore, people who have recovered from a serious illness drink more yogurt, which has an irreplaceable role in physical recovery. Therefore, it is also what people who have not recovered from a long illness need most.
Yogurt is not only nutritious, but also contains lactic acid bacteria, so it has health care function.
These functions are:
1. Maintain the ecological balance of intestinal flora, form a biological barrier, and inhibit harmful bacteria from invading the intestine.
2. Prevent constipation by producing a large number of short-chain fatty acids to promote intestinal peristalsis and a large number of bacteria to grow and change osmotic pressure. 3. Yogurt contains a variety of enzymes to promote digestion and absorption.
4. By inhibiting the growth of saprophytic bacteria in the intestine and the toxins produced by corruption, the liver and brain can be protected from these toxins and aging can be prevented.
5. By inhibiting the growth of saprophytic bacteria and some bacteria in the intestine. So as to inhibit carcinogens produced by these bacteria and achieve the purpose of preventing cancer.
6. Improve human immune function. Lactic acid bacteria can produce some substances that enhance immune function, which can improve human immunity and prevent diseases. Yogurt containing a large number of active bacteria is helpful to improve lactose intolerance, constipation, diarrhea, enteritis, helicobacter pylori infection and other diseases. The Human Nutrition Research Center of the US Department of Agriculture is conducting research on the elderly at Tufts University. Researcher Gene Mayer said that yogurt can not only improve the intestinal environment, but also improve human immunity. Coincidentally, a study in Taiwan Province Province also found that yogurt can improve the therapeutic effect of some anti-inflammatory drugs.
7. Lowering blood pressure: According to Dr. Alvaro A Liang, an epidemiological researcher at Harvard School of Public Health, the study found that people who drink 2-3 servings or more of yogurt every day have a 50% lower risk of hypertension than those who don't drink yogurt.
Nutritional analysis:
1. Yogurt can promote the secretion of digestive juice and increase gastric acid, thus enhancing people's digestive ability and promoting appetite.
2. Lactic acid in yogurt can not only turn weak acidic substances in the intestine into weak alkaline substances, but also produce antibacterial substances, which have a health care effect on the human body.
Mexican nutrition experts say that drinking yogurt regularly can prevent cancer and anemia, improve psoriasis and relieve malnutrition in children.
4. when making yogurt, some lactic acid bacteria can synthesize vitamin c and increase the content of vitamin C.
5. During pregnancy, yogurt not only provides necessary energy, but also provides vitamins, folic acid and phosphoric acid; It can also inhibit osteoporosis caused by calcium deficiency in female menopause; Eating yogurt every day in old age can correct the nutritional deficiency caused by partial eclipse.
6. Yogurt can inhibit the growth of intestinal spoilage bacteria, and also contains active substances that can inhibit the synthesis of cholesterol reductase in the body, stimulate the body's immune system, mobilize the body's positive factors, and effectively fight cancer. Therefore, regular consumption of yogurt can increase nutrition, prevent and treat arteriosclerosis, coronary heart disease and cancer, and lower cholesterol.
Don't think yogurt has many functions, even? If you can lose weight, drink more, no matter what food, enough is enough. Drinking too much yogurt will lead to hyperacidity, affect the secretion of gastric mucosa and digestive enzymes, and reduce appetite. Those who have hyperacidity, often feel weak spleen and stomach, and abdominal distension should not drink more. For healthy people, about 250 grams a day is more appropriate.
