2. The harm of eating fish on an empty stomach

First, it can easily cause gout

Most fish themselves are rich in purine. Eating fish on an empty stomach will cause a large amount of purine. If purine is ingested without enough carbohydrates to break it down, the body's acid-base balance will be imbalanced. Purine metabolism disorders will lead to an increase in blood uric acid and cause tissue damage, which can easily induce gout or aggravate the condition of gout patients. So this is the principle behind eating some low-fat foods containing carbohydrates before eating fish.

Second, it is easy to cause osteoporosis

Fish contains a lot of protein. If you eat a lot of fish on an empty stomach, it will cause animal protein in the human body. Excessive content causes an imbalance of acid-base balance in the human body, which not only increases the risk of diabetes, cardiovascular disease, and gout, but also accelerates the loss of calcium.

Third, it will lead to "protein waste"

High-protein foods are not milk and beans, but meat and fish. Meat and fish contain almost no carbohydrates. Except for about 70% water and a small amount of minerals, the rest is protein and fat. The protein content is much higher than soybeans. Eating fish on an empty stomach will "waste protein". That is, when the body needs energy, it has to break down protein because there are not enough carbohydrates (mainly found in grains, beans, fruits, and potatoes).
