Wang Lu, deputy director of the Nutrition Department of Beijing Hospital of the Ministry of Health, thinks that it is more beneficial to drink yogurt at night. Because from the point of view of calcium supplementation, because people no longer eat calcium-containing food at night, calcium metabolism is still quietly carried out during sleep, so it is necessary to eat a proper amount of calcium-rich dairy products before going to bed. So, which is more healthy to drink milk or yogurt at night? For most people, milk is a indigestible drink. After drinking it in the morning, you can digest it in your stomach after a day of exercise. After drinking at night, because the amount of exercise is greatly reduced after sleeping, it is not conducive to human digestion and absorption, and people with bad stomachs may have indigestion symptoms. Yogurt is different. The lactic acid it contains helps people's intestines and stomach peristalsis at night, so drinking it at night will not only lead to indigestion, but also help prevent constipation.
It is recommended that you drink yogurt about two hours after meals and avoid drinking yogurt on an empty stomach. Because lactic acid bacteria in yogurt are easily killed by gastric acid on an empty stomach, the health care function of yogurt will be weakened.
Benefits of drinking yogurt: yogurt is a long-lived drink. According to the earliest research results of Mechnikov (1845- 19 16), a Nobel Prize winner and Russian food expert, yogurt contains a growth active factor, which can enhance the immune function of the body and is beneficial to health, disease resistance and anti-aging. There are many longevity places in the world, and residents have a long-term habit of drinking yogurt. The reasons why yogurt is beneficial to human health and longevity may include:
1. Yogurt can enhance human immune function;
2. Reduce serum cholesterol level. Experiments have proved that even without any drugs. After drinking about 24 grams of yogurt per meal, cholesterol can be reduced after one week.
3. Regular consumption of yogurt can promote intestinal movement, shorten the transportation time of food from mouth to anus, soften the contents of glycolysis colon, increase fecal excretion, prevent constipation, and help prevent colon cancer. Therefore, yogurt is called "longevity food" abroad.
Yogurt is made from fresh milk fermented by lactic acid bacteria. Yogurt has the following nutritional values:
(1) Increase the absorption of nutrients: Yogurt not only retains all the nutrients of raw fresh milk, but also makes protein and lactic acid form fine coagulated milk, which can increase the digestion and absorption rate. At the same time, the calcium absorption rate in yogurt is higher than that in fresh milk.
(2) High vitamin C content: Some lactic acid bacteria can synthesize vitamin C, so the vitamin C content in yogurt is high.
(3) High lactic acid content: Lactic acid bacteria can decompose lactose in milk to form lactic acid, so it is more suitable for people who lack lactase and are prone to diarrhea after drinking fresh milk. Some people with gastric acid deficiency can improve their appetite and digestion by eating yogurt.
(4) It has a certain health care function: lactic acid bacteria can not only produce organic acids in yogurt, but also produce antibacterial substances, which can inhibit the reproduction of spoilage bacteria in the intestine and reduce the toxins produced by spoilage bacteria in the intestine, thus playing a better health care role. And has a certain effect of delaying aging.
Who should drink yogurt best? Most of the sugar contained in milk is lactose. However, due to the lack of lactase in the digestive juice of some adults, it affects the digestion, absorption and utilization of lactose, leading to stomach discomfort and even diarrhea after drinking milk, which is called "lactose intolerance". This is why many people don't drink milk. At this time, you can choose yogurt instead of milk without worrying about lactose. Yogurt contains lactic acid bacteria; Lactose in milk can be converted into lactic acid by lactic acid bacteria fermentation, and people who are lactose intolerant will not have diarrhea symptoms when drinking yogurt, which just solves the problems that may occur when some people drink milk. However, it is worth noting that many yogurt drinks (instead of yogurt) are made of milk, water and sour agents. Such products may also contain lactic acid, which may also lead to "lactose intolerance" symptoms.
1, patients with arteriosclerosis and hypertension. Some nutritionists have found that yogurt contains a "milk factor", which can lower human serum cholesterol. Calcium lactate in yogurt is easily absorbed by human body. Some people have done experiments, and drinking 720 grams of yogurt every day can significantly reduce serum cholesterol after one week.
2. Cancer patients. Lactobacillus bifidus in yogurt produces acetic acid, lactic acid and formic acid during fermentation, which can inhibit nitrate-reducing bacteria and block the formation of carcinogenic nitrosamines, thus playing a role in preventing cancer. Some countries with developed dairy industry in Europe believe that "a cup of yogurt every day can save women from worrying about breast cancer".
3. Old and frail patients. Lactic acid bacteria in yogurt can decompose lactose in milk to form lactic acid, make intestines acidic, inhibit spoilage bacteria that grow and reproduce in neutral or alkaline environment, and also synthesize nutrients such as vitamin B, folic acid and vitamin E, which are rich in protein and vitamin A itself, which is very beneficial to the elderly and the weak.
4. Those who use antibiotics. Antibiotics control pathogenic bacteria and inhibit non-pathogenic bacteria at the same time, which will lead to loss of appetite, nausea and vomiting, dizziness and so on. And even lead to another infectious disease. Yogurt contains active Mycobacterium longum, which can restore the imbalance of gastrointestinal flora.
5. Patients with osteoporosis. Yogurt contains calcium lactate which is easily absorbed by human body. This will increase patients' calcium, which is beneficial to the prevention and treatment of osteoporosis.
Drinking milk on an empty stomach is not conducive to the absorption and utilization of nutrients. Drinking yogurt on an empty stomach will make it difficult for lactic acid bacteria to survive in gastric juice, because the acidity in the stomach is too strong, which reduces the health care function of yogurt.
