We know that fish is a high-protein, low-fat food that is very beneficial for fat loss and body shaping. Therefore, many people like to enjoy a good meal of fish after a workout, thinking that this can effectively replenish nutrients, restore physical strength, and alleviate fatigue. However, the reality is the exact opposite. Japanese sports nutritionists believe that eating fish after exercise can lead to easier fatigue.
Many people often experience muscle soreness, joint pain, and mental fatigue after physical exercise. To relieve fatigue as quickly as possible, they buy and consume large amounts of chicken, fish, meat, and eggs, believing this can replenish nutrients and meet the body's needs. In fact, consuming these foods at this time not only fails to alleviate fatigue but can also have adverse effects on the body.
Human food can be classified into acidic and alkaline foods. The determination of a food's acidity or alkalinity is not based on people's sense of taste or its chemical properties when dissolved in water, but on the acidity or alkalinity of the final metabolites produced after the food enters the human body. Acidic foods are typically rich in protein and fat and contain elements such as potassium, sodium, calcium, and magnesium. After being metabolized in the body, they produce alkaline substances that can prevent the blood from becoming too acidic. Therefore, sour-tasting fruits are generally alkaline foods, not acidic foods. Although chicken, fish, meat, eggs, and sugar are not sour, they are acidic foods.
A U.S. pathologist, after long-term research, pointed out that only when the body's fluids are weakly alkaline can human health be maintained. The fluids of a healthy person are weakly alkaline. When a person feels muscle and joint soreness and mental fatigue after physical exercise, the main reason is the massive breakdown of sugars, fats, and proteins in the body. During this breakdown process, acidic substances such as lactic acid and phosphoric acid are produced. These acidic substances stimulate the body's tissues and organs, causing a person to feel muscle and joint soreness and mental fatigue. At this time, if one simply consumes acidic-rich foods like meat, eggs, and fish, it will make the body fluids more acidic, which is not conducive to relieving fatigue. On the other hand, consuming fruits and vegetables like vegetables, sweet potatoes, oranges, and apples, due to their alkalizing effect, can eliminate excess acid in the body, reduce the acidity of urine, increase the solubility of uric acid, and reduce the possibility of acid forming stones in the bladder.
Therefore, after physical exercise, one should eat more alkaline-rich foods, such as fruits, vegetables, and soy products, to help maintain the basic balance of the body's acid-base levels, maintain health, and quickly eliminate fatigue caused by exercise.
