Eat more green leafy vegetables and drink 8 cups of water every day… These are not wrong for healthy people or most people. They are health concepts, but they are most likely to be misread due to exaggerated publicity or people’s understanding of them out of context.
Prevention, a famous American health magazine, pointed out in an article that some concepts we believed in in the past were not applicable to everyone. The article also comprehensively “corrected” the interpretation of these six health concepts, to see if these concepts are still suitable for you?
One of the misconceived ideas: walking is the easiest way to exercise.
If you have a heart disease or live in a city with serious air pollution, you’d better not go out for a walk easily. Research shows that small particles in the air can increase the chance of heart attack. When you encounter cloudy weather, you should try to move indoors and turn on the air conditioner – it can reduce the indoor pollutant level by 50%.
The second misconception: swimming is the best aerobic exercise.
People with asthma should not believe this, because chlorine in the swimming pool can induce asthma attacks. In addition, parents should not bring allergic children under the age of 7 into the swimming pool.
The third misconception: we should eat more leafy vegetables.
People who are taking warfarin, a blood thinner, had better not take too much leafy greens in one day. The function of warfarin is to block the activity of vitamin K, thus avoiding thrombosis. Green leafy vegetables such as spinach and lettuce are rich in vitamin K, and eating too much will affect the efficacy.
Misread idea 4: drink 8 glasses of water every day.
Dan negoyanu and Stanley Goldfarb, M.D. of the University of Pennsylvania in the United States, said that no study can prove that people who reach the average health level should drink 1.6 liters (about 8 cups) of water every day.
According to the national health and nutrition survey of the United States, nearly 20% of the water in the human body is taken in through food. Excessive drinking water will destroy the water salt balance in the human body, cause “water poisoning”, and even lead to death. If you find that the color of your urine turns pale, you have enough water.
