Nutritional Logic and the Dialectics of Supplementation: Three Principles of Balanced Diet, Identification of Four Body Types, and Details of Staple Food Energy

A balanced diet is a fundamental principle of nutrition, meaning a diverse diet containing a complete range of nutrients in sufficient quantities and appropriate proportions. "Comprehensive" means eating a variety of foods to ensure a broad intake of the seven major nutrient groups; "balanced" means that the intake is in line with the body's needs. For example, men need protein and calcium to build strong muscles; insufficient intake leads to malnutrition, while excessive intake can cause nutritional deficiencies. "Appropriate" means that the proportions of various nutrients are reasonable; for example, older adults should consume a low-salt, low-sugar, and high-fiber diet.

Regarding tonics, there's a saying: "Tonics are like military strategy; indiscriminate use can harm the body." Six common misconceptions must be avoided: Misconception 1: Randomly taking tonics. Blindly supplementing without understanding one's constitution can disrupt the body's balance. Misconception 2: The more expensive the tonic, the better. While rhubarb can be a good tonic when used correctly, ginseng is useless if not properly taken. Misconception 3: The more the better. Excessive consumption can turn tonics into poison. Misconception 4: Overeating rich and greasy foods. Meat accumulates fat and cholesterol, easily triggering cardiovascular disease. Misconception 5: Taking tonics while ill. This should be postponed during a cold or fever. Misconception 6: Replacing food with medicine. Medicine cannot replace natural foods.

Dietary recommendations vary depending on individual constitution. Traditional Chinese medicine classifies constitutions into four categories: 1. Cold constitution: Characterized by obesity, aversion to cold, cold limbs, and in men, low libido, impotence, and low sperm motility. Suitable foods include ginseng, mutton, and goji berries; avoid cold and dampness. 2. Hot constitution: Characterized by thinness, dry mouth and tongue, and a tendency towards hypersexuality, premature ejaculation, and nocturnal emission. Meals should be light, avoiding spicy and hot foods; suitable foods include sand ginseng and ophiopogon japonicus. 3. Excess constitution: Characterized by impaired excretion and internal heat accumulation. Suitable foods include neutral foods and laxative foods. 4. Deficiency constitution: Characterized by insufficient vital energy and poor immunity. A balanced diet with nourishing foods is recommended.

For men to be physically strong, eating enough staple foods is crucial. Many men now avoid staple foods to lose weight, which damages the body's foundation. Wheat, corn, soybeans, and other seeds are the most energy-rich sources. Eating plenty of fiber-rich staple foods won't cause weight gain; it's high-protein, high-fat side dishes that lead to obesity. Staple foods should be varied; a mix of rice, sweet potatoes, and potatoes is even better.

Eating in accordance with the seasons is key to good health. Spring is for growth, summer for flourishing, autumn for harvest, and winter for storage; seasonal foods are essential to cope with seasonal changes. In summer, yang energy is on the surface and yin energy is internal, so ginger is good for warming the stomach; in winter, yang energy is drawn inward, so radishes are good for clearing stomach heat. In addition, eat more whole, small foods such as red beans and small fish, as their energy is most complete. Temperature control is also crucial. Sun Simiao pointed out, "Hot food injures the bones, cold food injures the lungs." The esophagus can only tolerate 50-60℃; frequently eating hot food can easily lead to mucosal degeneration and induce tumors. Cold food damages "stomach qi" and lowers immunity. The most suitable temperature is "neither too hot nor too cold," and the drinking water temperature should be between 18-45℃.

Bones are the body's support system. Traditional Chinese medicine believes that "the kidneys govern bones and produce marrow," so strengthening bones requires nourishing the kidneys. Two dietary therapy recipes are recommended: 1. Mulberry and Beef Bone Soup: Wash and steam 25 grams of mulberries. Boil 500 grams of beef bones in water, skimming off the foam, adding ginger and scallions. Once the bones turn white, add the mulberries, season, and drink. This soup nourishes yin and blood, benefits the kidneys, and strengthens muscles and bones. 2. Black Bean and Pork Bone Soup: Wash and soak 30 grams of black beans until soft. Simmer with 300 grams of pork bones until the beans are tender. This soup nourishes the kidneys, invigorates blood circulation, dispels wind and dampness, and is suitable for osteoporosis.
