A scientific diet can be summarized in 16 characters: focus on nutrition, emphasize health, strive for science, and ensure hygiene.
Entering the 21st century, in order to avoid the old path of unscientific diet and reduce "rich man's diseases" such as obesity, diabetes, heart disease, hypertension, and cancer, nutritionists have proposed adopting a scientific diet. Its key points are:
1. Balanced Nutrition: The proportions of various nutrients ingested should be appropriate, and the intake should be balanced with the body's needs. This includes a balance between required energy and its sources, amino acids, fatty acids, acid-base levels, vitamins, and minerals (both macro and trace elements).
2. Eat Dark-Colored Foods: Generally, natural dark and intensely colored foods are high in nutritional value, containing more vitamins, trace elements, and minerals, and have health benefits for the body. Excessive consumption of light-colored natural foods is detrimental to health, such as light-colored vegetables, sugar (refined white sugar), salt (refined salt), and refined grains.
3. Diverse Varieties: No single natural food can provide all the nutrients the human body needs, so one should not be a picky eater. A regular daily diet must include grains, tubers, animal foods, soy and its products, vegetables, and fruits. Within the same category of food, different varieties should also be frequently rotated, and combined with a variety of side dishes and snacks.
4. Avoid Rich and Heavy Flavors: Foods that are braised, roasted, pan-fried, or deep-fried are difficult to digest and absorb in the body, increasing the burden on the gastrointestinal tract and destroying the natural flavor. Overly salty and greasy foods are contributing factors to hypertension and cardiovascular diseases. Excessively sweet foods are closely related to obesity, diabetes, and cardiovascular diseases.
5. Scientific Food Pairing: Main dishes, side dishes, and snacks should be reasonably搭配, combining coarse and fine grains. The general ratio of carbohydrates, fats, and proteins is 58%, 30%, and 12%, respectively. At the same time, great importance should be placed on the intake of trace elements and dietary fiber.
6. Natural and Harmless: It is recommended to eat natural foods. Food raw materials and auxiliary materials for producing and processing food, including colors, flavors, seasonings, and additives, should all be natural substances, not artificial chemical compounds.
