Yogurt, also known as yogurt, is the product of milk fermented by Lactobacillus.
The method of making it is to keep fresh milk warm for a period of time, and then the bacteria will convert the lactose in the milk into lactic acid. This process is called fermentation, and the fermented milk is yogurt. Yogurt is a food in which microorganisms such as lactic acid bacteria are added to milk to ferment it, so that the lactose in the milk gradually converts it into lactic acid. Its nutritional content includes excellent milk protein, and the protein is transformed by the action of lactic acid or enzymes. It is in a form that is easily digested and absorbed and is rich in calcium, phosphorus and potassium. In particular, calcium content is as high as 120~140 mg per 100 grams of products. It is also an ideal source of vitamins A, B1, B2, B6, B12, folic acid and niacin for people with lactose intolerance. In other words, you can get the nutrients in milk without causing diarrhea. But the key to making yogurt lies in lactic acid bacteria (Lactobacillus), and lactic acid bacteria have poor heat resistance. Generally, the heat-resistant temperature is around 55 degrees Celsius. If it is higher, the lactic acid bacteria will die. The irony is that the purpose of drinking yogurt is to eat live lactobacilli into our stomachs. If we kill them, the dead bacteria we eat have no value. Therefore, we cannot microwave yogurt. !
As for the lactose in yogurt, it has been digested by lactic acid. After lactose is digested by lactic acid bacteria, lactic acid will be produced, which is beneficial to creating an acidic environment in the intestines and assisting the absorption and utilization of calcium and iron. In addition, lactic acid can promote gastric juice secretion and promote intestinal peristalsis to prevent constipation. function.
A moderate amount of yogurt can absorb a huge amount of live lactic acid bacteria, but those who are controlling their weight should pay attention to the fact that yogurt itself contains a considerable amount of calories, especially the type flavored with whole milk. Eating too much yogurt If you don't eat enough milk, you may gain a lot of weight. If you want to control your weight, you must choose low-fat, low-sugar and low-calorie yogurt.
