The four cornerstones of health are “proper diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance”, and to develop a healthy lifestyle, three major elements must be mastered. Element 1: Avoid risk factors. Smoking, alcohol abuse, high salt and (or) high fat diet, lack of physical activity and other lifestyle closely related to high blood pressure, hypertension, hyperglycemia, obesity, etc. has become a major enemy of the health quality of our people. These risk factors are risk factors that can be changed or avoided, so we are required to do a quit (quit smoking) and three limits (limit alcohol, salt and fat) in our daily lives to avoid risks. It is needless to say that the harm of smoking must be quit. Although it is said that moderate consumption of alcohol is beneficial to cardiovascular, but this moderate amount is difficult to define, do not agree to drink for this benefit, in addition, long-term alcohol consumption will increase blood pressure. High salt and high fat diet is the main problem, is the main risk factors for hypertension and other diseases, in 2012 the average daily cooking salt 10.5 grams, fat intake of 80 grams are far more than the WHO recommended standards. Factor 2: To control weight. Over the past 10 years, the intake of cereals and grains of urban and rural residents in China has remained stable. Total protein intake has remained basically the same, the intake of high-quality protein has increased, and the consumption of beans and milk is still low. Fat intake is excessive, with the average dietary fat supply ratio exceeding 30%. The intake of vegetables and fruits decreased slightly, and some nutrient deficiencies such as calcium, iron, vitamin A and D still exist. The national overweight rate for adults aged 18 and above is 30.1% and the obesity rate is 11.9%. Overweight is the common pathological basis of various chronic diseases, and only weight control can effectively intervene in the prevention and control of various chronic diseases. We advocate reasonable diet and moderate exercise for the purpose of weight control. The only way to control weight is to have a reasonable diet, moderate exercise and energy balance. Exercise should be done in three, five and seven. “Three” refers to a three-kilometer 30 minutes or more. “Five” refers to a minimum of five times a week exercise. “Seven” refers to the right amount of exercise. Reasonable diet is not not to eat, but to eat scientifically. To achieve “a reduction of five increase. “A reduction” refers to the reduction of fat intake, limited to about 25 grams per person per day, of which no more than 10 grams of saturated fatty acids (animal fat), to minimize the intake of trans fatty acids, monounsaturated fatty acids (camellia oil, etc.) is a better source of dietary fat, can reach about 20 grams. The “five increases” refers to increasing the intake of milk, green leafy vegetables, fruits and water. Element three, to improve sleep. Sleep is a reflection of mental health, but also plays an important role in the occurrence and development of many chronic diseases. Sleep disorders can trigger such as hypertension, diabetes, obesity and rheumatism and many other chronic diseases. Getting enough sleep can help keep you in shape, reduce your chances of developing type II diabetes, keep away anxiety and depression, and keep away dementia, osteoporosis and cancer. Only by vigorously advocating a healthy lifestyle and deeply popularizing the knowledge of sleep hygiene can we improve the overall health of the population. And a healthy lifestyle can help us improve sleep. 1, dinner should not eat non-consuming food, do not eat too saturated too greasy, do not drink, do not smoke to avoid overexcitation of the brain, before going to bed can be appropriate to eat some milk or other food to help sleep. 2, moderate physical exercise or exercise during the day or evening, but do not do strenuous exercise before bedtime. 3.Ensure psychological balance and relaxation. 4.Create a suitable sleep environment, comfortable sleeper as well as no excess noise. 5, to have a reasonable rest time, master the laws of human rest, at least half an hour before bedtime to stay away from electronic products.
