2. The survival rate of lactic acid bacteria in yogurt is closely related to the pH value in gastrointestinal tract. Lactic acid bacteria can grow and reproduce rapidly in weak acid environment, but it is difficult to survive in strong acid environment. When people are on an empty stomach, the acidity in the stomach is strong, and the acidity is relatively reduced after eating, so drinking yogurt on an empty stomach can't achieve the health care effect at all. Experts suggest that the best time to drink yogurt should be 65438+ 0-2 hours after meals.
Wang Lu, deputy director of the Nutrition Department of Beijing Hospital of the Ministry of Health, believes that drinking yogurt at night is more beneficial to health. Because from the point of view of calcium supplementation, because people no longer eat calcium-containing foods at night, calcium metabolism is still going on quietly during sleep, so it is necessary to eat a proper amount of calcium-rich dairy products before going to bed. So, which is more beneficial to health, drinking milk or yogurt at night?
I love to drink yogurt, but I heard that some yoghurts have live bacteria, and some yoghurts have no live bacteria. How to choose and drink it ... the "three wants and three don't want" of yogurt.
For most people, milk is a indigestible drink. After drinking it in the morning, you can digest it in your stomach after a day's exercise. After drinking at night, because the amount of exercise after sleep is greatly reduced, it is not conducive to human digestion and absorption, and people with bad stomach 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.
