Misunderstanding 1
Fruit can be eaten, but not eaten.
Wang Longde: The proportion of people in China, especially men, who often eat fruits is very low. Many people think that fruit is a snack, but you can eat it or not. In fact, fruit contains minerals that are necessary for human body but cannot be synthesized by itself, vitamins that have strong antioxidant effect and prevent cell aging, and soluble fiber pectin that can obviously reduce blood cholesterol concentration.
It is suggested to change from "eat fruit first" to "eat fruit first". Putting fruit before meals can ensure rapid digestion, effectively help control calories and supplement dietary fiber, minerals and trace elements.
Misunderstanding 2
Hyperlipidemia cannot eat egg yolk.
Wang Longde: Cholesterol is necessary to maintain normal metabolism. Cholesterol is 80% endogenous, and only 20% is exogenous from food.
Eggs contain a lot of lecithin, which is the substance to maintain memory and thinking. If you don't eat eggs or egg whites or yolks, you will lose many necessary nutrients.
Eating an egg every day is a very healthy lifestyle.
Misunderstanding 3
It doesn't matter if you eat too much vegetable oil.
Wang Longde: Many people think that vegetable oil is different from animal oil, and the cholesterol is not that high. It doesn't matter if you eat too much.
But what we don't know is that vegetable oil is high in calories. The same weight of vegetable oil provides more than twice as much calories as pork and more than four times as much as eel.
Excessive intake of vegetable oil is also very harmful, for example, 5 grams of oil is not consumed every day, and 20 kilograms will be added after 10 years.
In the pagoda of residents' balanced diet recommended by China Nutrition Society, the oil is on the top floor, and it should not exceed 25g (half a second) every day.
Misunderstanding 4
Not fat or thin, no exercise.
Wang Longde: Being neither fat nor thin does not necessarily mean that the health indicators are normal. Some people who are neither fat nor thin have unhealthy indexes such as cholesterol, triglyceride, blood sugar and bone density.
No exercise, unhealthy body structure and wrong proportion of muscle fat will also affect your health.
Myth 5
Exercise vigorously once a week.
Wang Longde: A lot of strenuous exercise can't replace the fitness effect brought by exercise on other days. People who are used to sitting still suddenly take a lot of exercise, and the risk of acute myocardial infarction is the greatest.
Exercise must be done step by step and often.
Myth 6
Exercise should "smell the chicken and dance"
Wang Longde: There is little oxygen in the air in the morning, especially in the Woods, because plants absorb oxygen and expel carbon dioxide at night; Cold in winter will stimulate the body, induce vasospasm and increase emergency.
In addition, blood viscosity is high in the morning, and blood pressure is easy to rise. Morning is also the "devil's time" for stroke, infarction and other diseases.
4-5 pm is the most suitable time for exercise in a day, and office workers can start appropriate exercise half an hour after dinner.
Misunderstanding 7
Mountain climbing is the best exercise.
Wang Longde: People's old legs will get old first. When climbing a mountain, they bear a heavy load, because one leg will break some joints or soften articular cartilage in the process from bending to straightening. Excessive load-bearing activities will accelerate its degradation and wear.
Middle-aged and elderly people try to climb fewer mountains and stairs.
Misunderstanding 8
Eating less can help you lose weight.
Wang Longde: Eating less will only affect the immune function, and your weight will rebound. Scientific weight loss is not dieting without eating, but paying attention to scientific diet and long-term reasonable exercise.
Taking shortcuts to lose weight is not worth the loss.
Myth 9
Local exercise can thin the waist.
Wang Longde: Exercise is a process of changing the metabolism of the whole body. Exercise consumes visceral fat first, then subcutaneous fat. Subcutaneous fat is also consumed first in places with a lot of blood flow, such as limbs and cheeks.
Only by doing full-body exercise can you consume fat, and it must be more than 20 minutes at a time. Short-term exercise can't lose weight, and local exercise can't lose weight.
Misunderstanding 10
Sweating a lot can lose weight.
Wang Longde: Water in human body mainly exists in body fluids and muscle cells, not in fat cells. After sweating a lot, you will feel thirsty, resulting in drinking a lot of water, and then quickly regain your original weight.
The advantage of sweating is that it can take away some metabolic wastes, but it is impossible to lose weight only by sweating a lot without insisting on moderate exercise.
