At present, there is a view that yogurts with active lactic acid bacteria as the selling point in the market are actually difficult to supplement lactic acid bacteria, which is not good for intestinal health. If the following items are true, this point can be refuted most:. ['Regardless of room temperature yogurt or frozen yogurt, the beneficial substances such as lactic acid, calcium and protein have been well preserved.', 'Most yoghurts on the market are of normal temperature and added type. Most of the lactic acid bacteria are killed during the production process and cannot be called "yoghurt".', 'The protein in yogurt has been thawed by lactic acid bacteria, so it is easily absorbed, which reduces the burden on digestion in the stomach.', 'The blood sugar response of yogurt is lower than that of staple foods such as rice steamed bread, and abnormal blood sugar response may cause a variety of symptoms.']
