Under the unit mass, the calories of beef and mutton are lower than those of pork, but they are still not as good as those of fish, shrimp and chicken. You burn more calories than you do. When you store this energy, you will get fat. But the problem is. Let's not talk about nutrition, just logic. You eat two catties of beef at a meal and don't eat pig's trotters all day. You said you would get fat.
Personally, what is the health of eating? Is nutrition balanced and healthy alone? I don't think so. I think eating delicious and favorite foods is healthy in a certain sense, because eating these foods will make you happy and mentally healthy. To evaluate modern people's healthy eating style, we can't just measure it by the proportion of nutrition or the health of food sources. Of course, I believe this classmate's question is from the perspective of nutrition. Nutritional value: Both pork and beef are red meat, and there are more saturated fatty acids than unsaturated fatty acids. Almost as bad as it is now.
It's just that beef is lean meat, and pork has high intramuscular fat, which makes it easier to gain meat. Taste: Because pork has intramuscular fat, it will be very fragrant when cooked in various dishes. Of course, some people like steak, commonly known as European stomach? What kind of meat to eat varies from person to person. However, eating only beef and not pork has few health problems. If your other food intake is simple, it is easy to cause some diseases caused by nutritional deficiency, but this is not caused by beef, but by the overall eating habits. In addition, the characteristic fatty acids of various meats are as follows: the content of saturated fatty acids in pork is high, the content of trans fatty acids and saturated fatty acids in ruminants (cattle and mutton) is high, and the content of polyunsaturated fatty acids in poultry (chicken and duck) is high, especially in ducks.
In fact, the nutritional value of meat can be measured by the ratio of saturated fatty acids (P: S). The phosphorus-sulfur ratios of pigs, cattle, sheep, chickens and ducks were 0.3 1, 0. 12, 0. 1 1, 0.66 and 0.82, respectively. p:S & gt； Nutrition recommendation 0.4 is better. From this point of view, the nutritional value of poultry meat is higher than that of livestock meat.
