Jelly is a nutritious snack. Wrong. Eating more jelly can not only supplement nutrition, but even hinder the absorption of some nutrients. Carrageenan, the basic component of jelly, is a carbohydrate that the human body can't absorb, and it doesn't contain fruit juice. Its sweetness comes from refined sugar and its fragrance comes from artificial essence. Fortunately, there is no fat in jelly, and it also contains water-soluble dietary fiber. Eating a small amount won't make you fat, but you can't expect it to increase nutrition. Can yogurt really lose weight? Yogurt is especially loved by consumers because of its rich nutrition and delicious taste. Moreover, among many women, there is a kind of yogurt diet, which says that yogurt is short in weight loss time, quick in effect and low in cost. The way to lose weight is to eat only fresh fruit for breakfast and 250g yogurt for lunch and dinner, and you can lose 3 to 5kg for several days. This statement has not been confirmed, and there is a saying that "yogurt can gain weight more than milk". The reason is that oligosaccharides, pectin, fructose and spices added in the processing of yogurt will increase the calories of yogurt, so people who are afraid of obesity need to choose carefully. Does yogurt have the effect of losing weight or is it in danger of getting fat? Li Baihua, director of the Nutrition Department of Peking University Third Hospital, was puzzled by the statement that yogurt can lose weight when interviewed by this reporter. She said that yogurt itself can never be said to lose weight, because the production method of yogurt only differentiates lactose in milk through lactic acid bacteria to form lactic acid, which has a special flavor and is conducive to absorption, but the original calories in milk have not changed. The principle of weight change is that if the intake of calories is lower than the consumption of calories, the weight will decrease, on the contrary, the weight will increase. It is impossible to lose weight because the calories of yogurt have not changed compared with milk. As for the statement that yogurt can make people gain weight more than milk, it is also established on the premise of reaching a fairly high intake. But whether it is milk, yogurt or other foods, excessive intake will cause weight gain. So generally speaking, eating yogurt will make people fat, which is unscientific. Director Li also mentioned that some consumers, especially women, regard yogurt as the first choice food in the process of losing weight, and only eat a cup of yogurt and some fruits every meal. This is because yogurt is rich in nutrition and high-quality protein, which will not cause malnutrition, and yogurt is delicious and most people like it. But the effect of losing weight is not because of eating yogurt, but because the total calorie intake is reduced, except yogurt and fruit, which do not consume the calories of other foods. From the perspective of nutritional balance, long-term simple intake of yogurt to lose weight will inevitably lead to malnutrition, and it is also possible to gain weight after returning to normal life, so it is necessary to be cautious to eat yogurt to lose weight. Yogurt is a long-lived drink. According to the earliest research results of Nobel Prize winner and Russian food expert Mechnikov (1845- 19 16), yogurt contains a growth active factor, which can enhance human immune function and is beneficial to health, disease resistance and anti-aging. There are many longevity places in the world, and residents have the habit of drinking yogurt for a long time. There may be the following reasons why yogurt is beneficial to human health and longevity: 1. Yogurt can enhance human immune function; 2. Reduce serum cholesterol level. Experiments have proved that even without any drugs. Drinking about 24 grams of yogurt per meal can reduce cholesterol after one week. 3. Regular consumption of yogurt can promote intestinal movement, shorten the transit time of food from mouth to anus, soften the contents of colon by glycolysis, increase the amount of fecal excretion, prevent constipation, and help prevent colon cancer. So yogurt is called longevity food abroad. Who should drink yogurt best? Most of the sugar contained in milk is lactose. However, due to the lack of lactase in digestive juice of some adults, it affects the digestion, absorption and utilization of lactose, causing 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, and don't worry about lactose. Yogurt contains lactic acid bacteria; Lactose in milk can be converted into lactic acid by lactic acid bacteria fermentation, and lactose intolerant people will not have diarrhea symptoms when drinking yogurt, which just solves the problems that some people may have when drinking milk. But it is worth noting that many yogurt drinks (not yogurt) are made of milk, water and sour agents. Such products also contain lactic acid, which can also cause lactose intolerance. 1, arteriosclerosis and hypertension Some nutritionists have found that yogurt contains a milk factor, which can lower the serum cholesterol in the human body. Calcium lactate in yogurt is easily absorbed by human body. Some people have done experiments, drinking 720 grams of yogurt every day can significantly reduce serum cholesterol after one week. 2. Lactobacillus bifidus in the yogurt of cancer patients produces acetic acid, lactic acid and formic acid in the fermentation process, which can inhibit nitrate-reducing bacteria, block the formation of nitrosamines, and play a role in preventing cancer. Some countries with developed dairy industry in Europe believe that a cup of yogurt every day keeps women from worrying about breast cancer. 3. Lactic acid bacteria in yoghourt of the elderly and infirm 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, which is very beneficial to the elderly and infirm. 4. Antibiotic users have suppressed non-pathogenic bacteria while controlling pathogenic bacteria, which may lead to loss of appetite, nausea and vomiting, dizziness, etc. , and may lead to another infectious disease. Yogurt contains active Mycobacterium longum, which can restore the imbalance of gastrointestinal flora. 5. The yogurt of patients with osteoporosis contains calcium lactate which is easily absorbed by people. This will increase patients' calcium, which is beneficial to the prevention and treatment of osteoporosis.
