Hello everybody, welcome to cancer prevention 60 seconds. The topic today is yoghourt. Yoghourt full of nutrition is suitable for all ages. Yoghourt can not only adjust gastrointestinal functions, but also improve immunity, lower cholesterol and prevent osteoporosis and cardiovascular disease among the elderly. Organic acid in yoghourt can increase peristalsis, stimulate gastric secretion and prevent constipation and bacterial diarrhea. Additionally, yoghourt can restrain cancer cell proliferation, being both cancer-preventive and cancer-treated. However, it is not proper to drink yoghourt with an empty stomach.
