Five "More"s and Five "Less"es for Your Spring Diet
[Introduction] In spring, all things flourish and thrive, and it is a period of peak physiological function and metabolism for the human body. However, with continuous spring rains, humid weather, and a climate that is alternately warm and cold, dietary care is crucial.
More Poultry, Less Livestock to Protect the Heart
Regarding meat, people often have a love-hate relationship. They love it for its rich nutrition and good taste, but fear its high fat content, which is linked to hyperlipidemia and even coronary heart disease, stroke, diabetes, and other diseases. How to solve this dilemma? One trick is to eat more poultry and less red meat.
Compared to red meat such as pork, beef, and mutton, poultry also contains animal fat, but its fat structure is different. Red meat is high in saturated fatty acids and cholesterol, while poultry like goose, duck, and chicken not only has less fat (only 1/4 to 1/3 of the former) but its fat structure is closer to that of olive oil, thus protecting the heart.
More Raw, Less Cooked to Reduce Carcinogens
When it comes to poultry, if you have both raw and cooked options in front of you, which would you prefer? Cooked meat products are convenient and tasty, so you might prefer them. However, this means you will be consuming nitrites. During the production of processed meats, nitrites are added for their preservative effect to keep the food fresh. But once in the human body, nitrites can break down into nitrosamines, substances with strong carcinogenic effects, posing a serious threat to health.
More Reducing, Less Oxidizing to Activate the Brain
How to maintain brain health and improve mental efficiency? Nutritionists point out: eat more reducing foods and fewer oxidizing foods.
Oxidizing foods refer to those rich in peroxidized lipid compounds, represented by fried foods, instant noodles, and hamburgers. High-calorie oily foods, fatty meats, and juices also belong to this category. These foods can undergo oxidation reactions in the body, damaging the normal molecular structure of cerebral blood vessel walls, narrowing them, affecting blood flow, and adversely stimulating the brain's physiological activities, leading to sluggish thinking.
Reducing foods, on the other hand, contain components like carotene and superoxide dismutase. They can prevent oxidation reactions in the cerebral blood vessel walls or "reduce" already-occurred oxidation reactions, ensuring unobstructed cerebral blood flow, adequate blood supply to the brain, and a state of constant clarity and activity.
More Coarse, Less Refined to Protect Blood Vessels
Currently, the incidence of cardiovascular and cerebrovascular diseases such as coronary heart disease and cerebral infarction is increasing, becoming the "number one killer" for the population. In addition to the traditional "highs"—high blood lipids, high blood pressure, and high blood sugar—another major culprit is hyperhomocysteinemia.
Experts have found that a substance called homocysteine, if its concentration in the blood is too high, can cause arteriosclerosis, ultimately leading to myocardial infarction, stroke, and Alzheimer's disease. One of the reasons for elevated homocysteine levels in the blood is the increasing consumption of finely processed foods.
More Green, Less White for a Longer Life
After analyzing the nutrients in various vegetables, nutritionists discovered a pattern: the nutritional value of vegetables is related to the depth of their color. The darker the color, the higher the content of vitamins and carotene, and vice versa. According to this pattern, the order is: green vegetables, red and yellow vegetables, and white vegetables.
Green vegetables are rich in calcium and have high levels of folic acid and vitamin C. Additionally, they are particularly high in chlorophyll, which has anti-cancer and disease-preventing properties.
