How important is it to eat and drink every day? Needless to say, diabetes, hypertension, hyperlipidemia, high uric acid, etc. are inseparably related to the irrationality of food, followed by cardiovascular and cerebrovascular diseases, uremia and other fatal diseases, so scientific and reasonable diet is the basis of disease prevention. When it comes to what to eat, many people always want to know what kind of food to eat. In fact, the human body is like a huge biological processing factory. The end product is life. The product is a comprehensive processing of a variety of raw materials, no raw material can be less, and there should be a proper ratio between the various raw materials. If the proportions are not right, the product produced may be defective. Therefore, the human body is very smart to grasp a principle when absorbing various nutrients from food. Overall absorption, that is, the more types of nutrients needed by the body in the food, the closer the ratio to the human body, the higher the absorption rate, and the higher the quality of the final product.

Research results show that a scientifically sound diet should be food variety. At least 12 kinds of food types should be eaten every day to meet the basic needs of the human body, and reaching 20 kinds is a goal to strive for every day. More than 25 kinds can be considered as high-quality food. Of course, the diversity of food choices is also required. The benefits to the body will be greater if you choose foods that may have a high nutrient density. So what is the nutrient density of food? Simply put, the nutrient density of a food refers to the amount of nutrients contained in a gas when it provides a unit of calories. For example, fatty foods are high-calorie foods, but they contain far fewer types of nutrients than fruits and vegetables, making them low-nutrient-density foods.

To realize that when all is said and done, the benefits to the body of eating foods with high nutrient density become greater. So what about the nutrient density of food in general? To food in the body's supply of vitamins, minerals, trace elements, proteins, sugar, fat, etc. to determine, in order from high to low: vegetables: especially a variety of green, red, orange vegetables, such as oilseed rape is actually more than milk to the human body to provide more calcium, oilseed rape than milk contains more of a variety of vitamins, minerals, the ratio is closer to the human body's needs, so every day in the food of a variety of vegetables Can not be less than 500 grams. Fruit: a variety of fresh fruit is good, can not peel people can not eat more than 250 grams per day. Cereals: Requirements are whole grain foods. Simply put, it is not overly processed. The lower the nutritional density of microfine rice flour, the better 4-6 per day. dairy products: milk, yogurt, cheese can be, but in the processing should pay attention to not add sugar, 200-300 grams per day is appropriate.

High-protein food: animal food is best fish, followed by poultry, it is best not to eat or eat less animal husbandry. Plant foods are mainly beans, animal and plant foods should be more than 100 grams per day. In addition, you can also supplement 10-15 grams of nuts rich in high-quality protein. Fatty foods: including vegetable oils and fats from animal foods, should not exceed 25 grams per day. To summarize, only according to the nutritional density of food rational arrangement of the day to eat and drink, in order to provide the body with the appropriate proportion of nutrients, processing high-quality products - healthy life.
