A balanced diet means that people have a good number of nutrients in their diet, a reasonable proportion, scientific and suitable, and they have a wide range of ingredients. Therefore, with nutrition as the guide, a balanced diet is the most reasonable diet for humans. It can provide the human body with sufficient calories, protein, fats, carbohydrates, and plenty of inorganic salts, vitamins and the right amount of cellulose, both to meet the various needs of the body, but also to prevent a variety of diseases.
The characteristics of a balanced diet
1. There should be a variety of foods in the diet, including a variety of foods needed by the body.
2, the proportion of food in the diet should be suitable, not only should pay attention to a variety of nutrients complete, but also proportional to scientific, reasonable and appropriate.
3. On the basis of a balanced diet, we must also pay attention to the rational processing of cooking, matching of main and non-staple foods, and diversification of recipes to ensure good appetite and adequate and reasonable nutritional intake.
The composition of a balanced diet
In order to facilitate the planning of daily balanced diets, many countries classify foods into several major categories. The classification method differs depending on the conditions. At present, according to our national conditions, our country divides food into five major categories, namely the five main types of foods that should be included in the balanced diet: 1. cereals (grain) and cereal products; 2. legumes and legumes; 3. fish and eggs Milk; 4, vegetables and fruits; 5, fats and oils. In general, the proportion of carbohydrates, fats, and proteins in a balanced diet is 5:1.5:1, the ratio of heat energy is 60% to 70% for carbohydrates, 20% to 25% for fat, and 10% to 15% for proteins. These conditions of diet should include the above five categories of food.
Implementation of a balanced diet
The implementation of a balanced diet requires a reasonable system for guarantee. First of all, it is necessary to make reasonable arrangements for daily meals and intervals, to develop the habit of regular meals, while paying attention to the distribution of the number of meals, the more reasonable distribution of the number of meals is: breakfast heat accounts for 30% of the total heat energy of the day. About 40% of lunch and 30% of dinner. Abandonment of breakfast is not desirable. Dinner is overdone. It is not only easy to cause obesity but also may cause angina pectoris and myocardial infarction. It is even more taboo for middle-aged and older people. Secondly, the proportions of various nutrients in food should be scientifically, rationally, and appropriately distributed, and there must be an appropriate amount of fresh vegetables and fruits. This kind of dietary structure can basically reach a balance. In addition, a balanced diet can be achieved with good drinking habits, including chewing and swallowing, adequate sleep, work and rest, happy mood, concentrating on eating, and good hygiene habits.
A balanced diet is mainly for healthy people and is also suitable for patients. In the disease state, due to the different needs of the body, the difference in metabolic state, and the differences in the status of water and electrolytes, it is necessary to address the specificity of the condition of a balanced diet.
The overall goal of a nutrition-oriented balanced diet is to achieve a diet that is conducive to the development and growth of human beings, conducive to human labor and creativity, conducive to the prevention and treatment of related diseases, and conducive to human health and longevity.
