Human: Is it true that if you drink a glass of milk everyday you won't get a cold? Assistant: 
No, drinking a glass of milk every day is not likely to prevent a cold. Milk contains many vitamins and minerals but the most important one for preventing colds is Vitamin C. The recommended daily allowance (RDA) for vitamin C is 75-90 mg/day for adults. Drinking a glass of milk provides about 20% of the RDA. So, no, drinking a glass of milk every day is not likely to prevent a cold.
