Food Intake and Lifespan: How Much to Eat for a Healthy Life?

In recent years, the notion that "food intake determines lifespan" has been circulating widely online, with many people worrying that eating too much could accelerate the passage of life. So, is food intake truly intertwined with lifespan? And just how much is considered healthy to eat?

I. Does Eating Too Much Really Shorten Life?

The answer is yes. Eating too much and overeating can indeed negatively impact health and indirectly affect lifespan.

1. The Dangers of Obesity: Long-term overconsumption of energy leads to obesity, which is a risk factor for various chronic diseases. According to Traditional Chinese Medicine, "when Qi and blood are not in harmony, all diseases arise from their changes." Obesity can hinder the smooth flow of Qi and blood, easily leading to stagnation of Qi and blood clotting, ultimately causing various illnesses. Modern medical research has also confirmed the close relationship between obesity and chronic diseases such as heart disease, diabetes, and hypertension.

2. The Wisdom of "Seven-Point Fullness": Ancient people were well aware of the importance of "not overeating and not drinking excessively." The book "Yangsheng Yanming Lu" advocates for "seven-point fullness," meaning one should stop eating when they feel full but could still consume a small amount of food. This aligns with the concept of "moderation in eating" promoted in the "Huangdi Neijing."

II. Can Long-Term Dieting "Extend Life?"

Long-term dieting is not a shortcut to "extending life" and can even harm health.

1. Traditional Chinese Medicine Perspective: TCM believes that moderate dieting can help regulate the spleen and stomach, promoting the generation of Qi and blood. However, excessive dieting can lead to malnutrition, affecting the normal function of bodily organs.

2. The Health of the Spleen and Stomach: The spleen and stomach are the "foundation of the acquired constitution," responsible for nutrient absorption and transformation. Excessive dieting directly harms the spleen and stomach, affecting nutrient absorption and, subsequently, the function of vital organs like the heart and lungs.

III. How to Manage Three Meals a Day Healthily?

Healthy eating habits are crucial to extending lifespan. To achieve "nourishing the body through food," we need to correctly understand the wisdom of health preservation, cultivate healthy eating habits, maintain a reasonable food intake, and consume balanced nutrition.

1. Regular Timing and Quantity: "Yinshan Zhengyao" emphasizes the importance of eating at regular intervals and in appropriate quantities. A reasonable dietary arrangement includes:

• Breakfast: Consuming sufficient protein to provide energy for the day's activities.

• Lunch: Consuming sufficient energy to support life activities throughout the day.

• Dinner: Avoid overeating or consuming overly greasy foods, as these can affect sleep quality.

2. Chew Thoroughly and Slowly: "Yangsheng Siyao" emphasizes "chewing thoroughly and slowly for better digestion." Chewing thoroughly and slowly can reduce the burden on the stomach and intestines, promote digestion and absorption, and also slow down the rise in blood sugar levels, preventing hyperglycemia.

3. Standardize Dietary Structure: "Lao Lao Heng Yan" suggests "adjusting to the individual." Different constitutions, age groups, and health conditions require different dietary structures:

• Seniors: With weaker spleens and stomachs, they should choose soft and easily digestible foods.

• Children: Growing and developing require sufficient nutrition, ensuring both food quantity and nutrient richness.

• Individuals with a Cold Constitution: They can consume warming and nourishing foods like ginger and mutton.

• Individuals with a Hot Constitution: They should choose cooling foods like mung beans and winter melon.

IV. How to Determine a Reasonable Food Intake?

A reasonable food intake varies from person to person, influenced by factors such as age, gender, constitution, and activity level. Generally speaking, the following standards can be used as a reference:

• Adult Males: Daily energy intake of approximately 2200 kcal, equivalent to 2-3 taels of rice, 2-3 taels of meat, and 4-5 taels of vegetables.

• Adult Females: Daily energy intake of approximately 1800 kcal, equivalent to 1.5-2 taels of rice, 1-2 taels of meat, and 3-4 taels of vegetables.

V. What to Eat for Better Health?

A healthy dietary structure should emphasize diversity and balance, including the following aspects:

• Staple Foods: Choose whole grains and mixed grains like brown rice, oats, and millet as the main staples, supplementing with appropriate amounts of polished rice and white flour to ensure carbohydrate intake.

• Protein: Choose high-quality protein sources such as fish, beans, eggs, and milk, avoiding excessive intake of red meat.

• Vegetables: Consume at least 300 grams of vegetables daily, with a variety of types, including dark green vegetables, orange vegetables, and mushrooms.

• Fruits: Consume 1-2 servings of fruit daily, choosing seasonal fresh fruits and avoiding overly sweet fruits.

• Fats: Choose plant oils like soybean oil, corn oil, and olive oil, avoiding excessive intake of animal fats.

• Water: Ensure adequate water intake daily, drinking at least 1.5-2 liters.

VI. Other Factors Affecting Lifespan:

Besides diet, good lifestyle habits and practices can also extend lifespan, including:

• Adequate Sleep: Ensure 7-8 hours of sleep daily.

• Moderate Exercise: Engage in at least 3-4 sessions per week, each lasting 30 minutes, choosing exercise forms suitable for your own condition.

• Good Mindset: Maintain an optimistic and positive mindset, avoiding excessive emotional fluctuations.

• Regular Health Checkups: Undergo regular health checkups to detect potential health problems early and take proactive preventive measures.

VII. Conclusion:

Food intake and lifespan are related, but it's not a simple matter of "eating more means a shorter life." Reasonable eating, balanced nutrition, good lifestyle habits, and a positive mindset are all crucial factors in extending lifespan. Avoid blindly pursuing dieting or overeating. Instead, choose a healthy eating style suited to your own situation, allowing food to become a safeguard for health rather than a burden on life.
