Eat 300 grams (11 oz) per day
To increase good bacteria in the intestines by eating yogurt, 300 grams of yogurt is necessary to eat a day. So it is recommended to eat yogurt not only once a day but a few times a day.
Eat after meals
Before meals, the stomach acid is strong so if you eat yogurt before meals, lactic acid bacteria in yogurt die.
Change the brands of yogurt every month
It takes about 2 weeks to 1 month to harmonize the environment of the intestines so it is good to keep eating the same yogurt for 2 weeks to 1 month. But once the environment is harmonized, the bacteria become inactive. To activate the function of bacteria, it is good to add new kinds of bacteria by changing the brands of yogurt.
