To pay attention to the ten myths in health care Myth 1: egg yolk contains a lot of cholesterol, high blood lipids can not eat egg yolk. Wang Longde said, cholesterol is a very physiological need of a substance. The vast majority of cholesterol in the human body is its own synthesis, only 20% is the intake of outside the body, and cholesterol intake does not depend on the amount of cholesterol itself, but on the amount of fat in food. Egg yolk contains more cholesterol, but there are many other nutrients that are very beneficial to the human body, especially lecithin. Myth 2: Fruit is a snack, can eat or not. According to the results of a survey, people who eat less fruit at the age of 50 have a higher mortality rate from cancer. Myth 3: Animal oil is bad if you eat too much, but vegetable oil is unsaturated fatty acid, so eating too much has no effect on the body. In fact, this is not true, the calories of vegetable oils and animal oils are the same, you eat in as long as the consumption will become their own fatty acids. Myth #4: A lot of vigorous exercise once a week is also good for your body. A lot of strenuous exercise once a week is bad for your health. Exercise should be frequent, not suddenly a substantial and strenuous exercise. Myth 5: Fat people go to exercise, I do not need to go to exercise, you see how standard my body. If you do not exercise, your body structure is unhealthy, that is, the ratio of muscle and fat is not right, the same will affect the health of the body. Myth 6: Doing some local exercise can make the waistline decrease. Exercise is to adjust the state of the entire body, only to do a full-body exercise to burn fat, and exercise must exceed 20 minutes at a time. Therefore, a short period of exercise is not able to lose weight, and local exercise can not lose fat. Myth 7: You can lose weight by eating less. Eating less can only affect the immune function, and the weight will rebound. Myth 8: You can lose weight by sweating a lot. It is not right to think that you can lose weight by sweating a little more by taking sauna baths and so on. Myth 9: Climbing is the best exercise. People old legs first old, climbing when the weight is very powerful, because there is a leg from curved to straight process, in the process of straightening will cause some joint fractures, or cartilage cartilage of the joints, excessive weight-bearing activities to accelerate its degeneration and wear. Therefore, the middle-aged and elderly people try to climb as little as possible, climbing buildings. Myth 10: smell the chicken. In the morning, it can be said that the relative content of oxygen in the air is relatively small, especially in the woods, because plants are the same as people at night, is to absorb oxygen and discharge carbon dioxide, only after photosynthesis to discharge oxygen. In addition, the low temperature can also increase the number of sudden events. In addition, early morning blood viscosity is high, blood pressure is easy to rise, in this time like stroke, heart attack are more incidence.
