Many people think that eating more fish, seafood or chicken is healthier and more nutritious than eating pigs, cows and sheep, and eating fish is less likely to get fat. However, food experts say that they are actually equally nutritious, such as salmon, cod, saury, milk fish and so on. Fish has a high fat content, so eating too much will lead to obesity, so moderate amount is better.
According to the American Journal of Clinical Nutrition, eating red meat and white meat has no obvious effect on cholesterol in human blood. Experts say that, in fact, fish and meat are excellent sources of protein in food classification. Although the proportion of nutritional components is not exactly the same, they all have high nutritional value.
Although the fatty acids in red meat such as pigs, cattle and sheep are mostly "saturated fatty acids", which will increase blood lipids and increase the risk of cardiovascular diseases, white meat such as fish and seafood contains a high proportion of "unsaturated fatty acids", which has a preventive effect on cardiovascular diseases. However, experts say, "as long as you eat it in a balanced way, meat and fish are just as good!" 」
Eating more red meat will raise blood lipids and increase the risk of cardiovascular disease.
For meat, protein is rich and has high utilization rate in human body. It is also rich in B vitamins and minerals, such as zinc and iron, which can repair tissues, enhance physical strength, increase resistance and prevent anemia. In addition to the high content of unsaturated fatty acids, the overall fat content of fish is less than that of meat, and the fish structure has less connective tissue, which is easy to digest and absorb, and the vitamin content is similar to that of meat. But the iron content in fish is less than that in meat.
Many people think that eating fish will not make you fat, but experts say that eating too much will also lead to high blood lipid and obesity. For example, salmon, cod, saury, milk fish and other fish have relatively high fat content. For example, the fat content of saury is only a little less than that of pork belly, while the protein content of parts with high fat content such as fish belly and skin is relatively low. If you want to eat protein, these parts are not the best.
Experts point out that the iron content of meat is higher than that of fish. For people with iron deficiency or high iron demand, such as girls in physiological period, a proper amount of red meat can supplement enough iron to avoid insufficient iron intake.
