Health misunderstandings you must understand

　　Milk makes phlegm
　　
Many mothers dare not give cold Some children drink milk because milk produces phlegm. An Australian research team recruited volunteers and infected them with rhinovirus, the causative agent of the common cold. After 10 days of observation, they found no link between drinking milk and phlegm secretion. People's subjective understanding that milk produces phlegm is because milk makes our saliva become sticky, making it feel like there is phlegm.

Eating before going to bed can make you gain weight
　　
Girls who want to be slim are often told not to eat before bed because sleep During this period, people's metabolism is slow, calories cannot be "burned" by the body, and energy is more easily converted into fat and stored. In fact, the calories you consume at night are no different than the calories you consume during the day. The reason for this misunderstanding is that people often choose snacks such as biscuits and potato chips for snacks before going to bed, which are high-calorie foods.

　Vitamin C can prevent colds
　　
American chemist Pauling, winner of the 1954 Nobel Prize in Chemistry and the 1962 Nobel Peace Prize, wrote a book called "Vitamin C and the Common Cold." The main point in the book is that taking 1,000 mg or more of vitamin C every day can prevent colds; vitamin C is antiviral.

However, several large-scale experiments have confirmed that although vitamin C can help relieve symptoms in cold patients, there is no credible evidence that taking large doses of vitamin C can prevent colds, whether in adults or children. It should be noted that taking large doses of vitamin C for a long time may cause diarrhea、anemia and urinary tract stones. Doctors recommend that daily vitamin C intake should not exceed 200 mg.
