It is not advisable to eat acidic foods such as fish after exercise. Chongqing nutrition and sports experts said that after exercise, sugar, fat and protein in the human body are decomposed in large quantities in the absence of endogenous oxygen, resulting in acidic substances such as lactic acid and phosphoric acid, which will stimulate human tissues and organs and make people feel sore muscles and joints and mental fatigue.

Fish and other foods are acidic foods. Eating these acidic foods after exercise will make body fluids more acidic, which is not conducive to the relief of muscle and joint pain and physical fatigue. After exercise, you should eat more alkaline foods such as fruits, vegetables and bean products to keep the acid-base balance in the human body, so as to eliminate exercise fatigue and keep healthy.
