We know that fish is a food high in protein and low in fat, which is very beneficial for fat loss and body shaping. Therefore, many people like to have a nice meal of fish after a workout, thinking that this can effectively replenish nutrients, restore physical strength, and reduce fatigue. However, the reality is the exact opposite. A Japanese sports nutritionist found that eating fish after exercise can lead to easier fatigue.
A U.S. pathologist, after long-term research, pointed out that the body can only maintain health when its body fluids are slightly alkaline. After physical exercise, the feeling of soreness and swelling in muscles and joints, as well as mental fatigue, is mainly due to the large-scale breakdown of sugars, fats, and proteins in the body. During this breakdown process, acidic substances such as lactic acid and phosphoric acid are produced. "At this time, one should eat more alkaline-rich foods, but fish is an acidic food. Eating fish after exercise will acidify the blood. Coupled with the large amount of lactic acid produced in the body, it will worsen the degree of fatigue," explained the sports nutritionist.
Therefore, after a workout, you can eat milk, vegetables, fruits, seaweed, soy products, etc., to maintain the body's acid-base balance; it is not advisable to eat chicken, fish, or eggs. It is worth reminding that the determination of a food's acidity or alkalinity is not based on people's sense of taste, nor on 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. Sour-tasting fruits are generally alkaline foods, while chicken, fish, meat, eggs, and sugar, although not sour in taste, are acidic foods.
