Yogurt should not be drunk on an empty stomach, and it is best to drink it two hours after meals. For healthy people, it is not advisable to drink a lot at a time. It is more appropriate to drink one or two cups a day, each cup is about125g.
Because the PH value suitable for the growth of lactic acid bacteria is below 5.4, on an empty stomach, people's stomach acid is higher, the PH value is below 2, and the gastric juice is diluted after meals, and the PH value rises to 3.5. Therefore, drinking yogurt on an empty stomach is easy to kill lactic acid bacteria and weaken health care function.
Although yogurt has so many benefits, we should pay attention to the right amount when drinking it, otherwise it will easily lead to hyperacidity, affect the secretion of gastric mucosa and digestive enzymes, reduce appetite and destroy the electrolyte balance in the human body. Especially people who usually have too much stomach acid and often feel weak spleen and stomach and abdominal distension should not drink more.
Extended data
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.
Precautions:
1, it is not advisable to drink yogurt on an empty stomach.
The PH value suitable for the growth of lactic acid bacteria is below 5.4. On an empty stomach, people's stomach acid is high, and the PH value is below 2. After meals, the gastric juice is diluted and the PH value rises to 3.5. Therefore, drinking yogurt on an empty stomach is easy to kill lactic acid bacteria, and the health care effect is weakened, but drinking yogurt two hours after meals is better.
2, unfavorable heating
Active lactic acid bacteria in yogurt are beneficial and harmless to human body, which can decompose lactose in fresh milk to produce lactic acid, increase intestinal acidity, inhibit the growth of spoilage bacteria and weaken toxins produced by spoilage bacteria in intestinal tract. In addition, active lactic acid bacteria also have the function of enhancing gastrointestinal digestion. After heating and boiling, not only the unique flavor of yogurt disappears, but also the beneficial bacteria in it are killed, and the nutritional value is greatly reduced.
3, the baby should not feed yogurt.
In modern families, it is often seen that parents feed their babies with yogurt. In fact, this practice is unscientific. Although yogurt can inhibit and eliminate the growth of pathogenic bacteria, it also destroys the growth conditions of bacteria beneficial to infants and affects normal digestive function.
People who drink milk and have bloating can drink yogurt.
Some people will produce gas in their stomachs after drinking milk, feeling bloating and even diarrhea. This is because these people lack lactobionic acid, and lactose in milk cannot be decomposed by glycosidase in the small intestine, that is, it enters the large intestine and is fermented by other bacteria in the large intestine to produce gas. However, these people will not have the above phenomenon when drinking yogurt, because lactic acid bacteria in yogurt have decomposed lactose in milk during fermentation and converted it into sugars that are easily absorbed by the human body. So people who drink milk and have bloating can drink yogurt.
5. Applicable people and precautions for skim yogurt and full-fat yogurt: Diabetic patients, patients with atherosclerosis, cholecystitis and pancreatitis are best not to drink full-fat yogurt containing sugar, otherwise it will easily aggravate the condition and affect the treatment effect. Sugar-free skim yogurt is more suitable. However, for young people who are busy with work and have a large amount of labor, it is beneficial to drink sugary full-fat yogurt, which can quickly replenish their physical strength.
6. Yogurt can prevent constipation and bacterial diarrhea, in which organic acids can increase intestinal peristalsis, stimulate gastric juice secretion and inhibit the production of harmful bacteria in the intestine. Especially for people with weak gastrointestinal function and those who take antibiotics, active bacteria in full-fat and sugary yogurt can restore the imbalance of gastrointestinal flora.
7. It is best to drink yogurt after meals, because the environment in human stomach is the most suitable for tyrosine growth, so as to play more health care roles. Especially 2 hours after meals.
