Recently, a bowl of old yoghurt that looks like a soft bean curd and needs to be eaten with a spoon has been set on fire. Why do we need to add an “old†character to the yogurt? Can this old yogurt be healthier and more nutritious than regular yogurt? Today, the concept of healthy yogurt is becoming more and more popular, and drinking yogurt is also very knowledgeable.
Yoghurt is made by fermenting fresh milk with lactic acid bacteria. Its taste is sweet and sour, and it is nutritious. It is loved by people. Experts called it "food in the 21st century" and "a unique nutritional product."
The nutritional value of yogurt
(1) Digestible protein and fat increase in yogurt. Yogurt during the fermentation process soluble protein, non-protein nitrogen and amino acid content increased, according to the calculation of yogurt protein digestion and absorption performance is twice the milk protein; yogurt during the fermentation process to increase the free fatty acid content in milk, easier Absorbed by the body. Similarly, yogurt increases the availability of calcium and phosphorus and promotes the absorption of iron and vitamin D.
(2) Yogurt contains vitamin C, B and other nutrients. Some lactic acid bacteria can synthesize vitamin C, so the content of vitamin C in yogurt is high. At the same time, the content of vitamin B1 and vitamin B2 in yoghurt was increased during the fermentation process.
(3) High lactic acid content in yoghurt: Lactose is mostly decomposed into lactic acid during the fermentation process, which can be suitable for more consumer groups. Lactic acid can increase appetite and increase digestion.
(4) yogurt has a certain role in health: lactic acid bacteria in addition to the production of organic acids in yogurt, but also produce antibacterial substances, can inhibit the proliferation of spoilage bacteria in the intestine to reduce spoilage bacteria produce toxins in the intestine, play a better Health effects.
(5) The content of choline in yogurt is high. Regular consumption of yogurt can reduce serum cholesterol, enhance immunity of the body, and reduce the incidence of cardiovascular disease in the elderly.
New "old" yogurt rich in protein
The old yoghurt belongs to the solidified yoghurt, and the nutrition is better than the stirred yoghurt, mainly reflected in two aspects. First, the protein content is higher. High-quality yoghurt is made from high-quality milk, and the protein content is mostly 2.3-3 g/100 g. In order to make the old yoghurt more viscous, its protein content, especially whey protein, is usually increased during the production process. This production method makes the old yoghurt more easily absorbed by the body; and the fat and lactose content is very low.
Second, no additives. Ordinary yoghurt may add various sweeteners and flavor enhancers. Many people drink old yoghurt and drink it is a simple, because its taste is closer to the original porcelain yogurt.
The old yoghurt has a simple, delicate taste and is like a cream, which is more expensive than regular yoghurt. Therefore, if everyone wants to drink the "old yoghurt" with higher cost performance, it might be worthwhile to buy a yogurt machine. Homemade yogurt at home is both affordable and healthy.
Drink yogurt in the right amount
Yogurt is as fresh as possible. Yogurt can be stored at 4 °C for more than 14 days. Under the condition of refrigerating at 4°C, the amount of lactic acid bacteria in yogurt will slowly decrease, and the number of viable cells will decrease to approximately one-tenth of original ones after 14 days. Therefore, try to drink fresh yogurt as much as possible.
The amount of yoghurt consumed varies from case to case. Normal dieters drink 1-2 cups of yogurt (250-500 grams) a day. For teenagers, a cup of yoghurt in the morning and evening, or a cup of milk in the morning, a cup of yoghurt at night is the best. However, this does not mean that the amount of yogurt can not be increased. When the appetite is not good, the diet is not adjusted, the body is weak, and the intestinal tract is infected and cannot eat normally, you can drink more yogurt every day to absorb nutrients, adjust the gastrointestinal function, and improve the body's resistance. The recovery of intestinal infections.
Some people are particularly fond of yoghurt and often drink plenty of yogurt after a meal, which can cause weight gain. This is because yoghurt itself contains a certain amount of energy, and drinking yogurt after a meal is equivalent to an additional intake of this energy, which may cause weight gain. Therefore, people who are particularly fond of yoghurt after a meal should pay attention to properly reduce their food intake or reduce other snacks and fruits in order to achieve a balance of energy supply and maintain a stable weight.
I can also drink yogurt before eating
In general, yogurt can be consumed at any time except when hunger is strong. Eating yoghurt before a meal can suppress hunger to a certain extent, and it can also provide nutrition for the body.
Many people have heard that they cannot drink yoghurt before meals for three reasons. First, yoghurt protein is wasted on an empty stomach. Second, lactic acid bacteria die under strong stomach acid conditions, impeding the use of their health effects. Third, lactic acid in yogurt. Has a stimulating effect on the stomach. In fact, these three reasons cannot prove that fasting must never drink yogurt.
First of all, ordinary sweet yogurt contains 7% of sucrose and about 3% of lactose, which can provide the body with heat, and the protein content is only 2.5%. Therefore, when yoghurt is taken on an empty stomach, the protein in the yogurt will not be wasted.
Moreover, in addition to hunger is very strong, the stomach before meals is not necessarily completely empty, and the stomach acid content is not necessarily high. Therefore, lactic acid bacteria may not be completely killed.
Even if lactic acid bacteria are dying in large numbers, some health effects may be affected, but the nutritional value remains unaffected. Studies have shown that the bacterial fragments and extracts of lactic acid bacteria still have a certain degree of health care, and it is better to drink than to not drink.
The acidity of yoghurt produced in our country is lower than that of western countries, and the sugar content is relatively high. In addition, the protective effect of protein and gum on the yoghurt will not cause great stimulation to the stomach of healthy people. Therefore, for people with normal gastrointestinal function, yoghurt before meals does not interfere.
However, some people cannot drink yogurt on an empty stomach. Those with stomach ulcers and hyperacidity should pay special attention. Those who suffer from cold abdominal pain do not drink yoghurt that has just been taken out of the refrigerator. At room temperature, wait for half an hour before drinking, and you will not feel unwell.
Medication period different treatment
Some people think that when taking antibiotics can not drink yoghurt, but most of the relevant scholars believe that taking antibiotics can cause disorders of the intestinal flora, but also reduce the immunity, but also often take yogurt to adjust the balance of the flora to protect the body resistance. After stopping the drug, continuing to drink yogurt for a period of time can greatly reduce the side effects of antibiotics and restore the balance of normal human flora.
Taking nutrients such as vitamins and minerals can be delivered with yogurt. Yogurt contains fat, sugar and protein ingredients that protect nutrients and promote absorption. However, other drugs may not be delivered with yogurt, especially drugs containing heavy metals and drugs containing alkaline substances.
