Red meat, usually considered to be beef, pork, mutton and lamb products, have nutritional value, but eating red meat also raises some health concerns.
Red meat is an excellent source of protein(蛋白质). It is also a key source of vitamin B12, which is only available in animal products and is key for both red blood cell and nerve health. Red meat is also a rich source of zine, selenium(硒) andiron. Zinc and selenium are good for our immune system (免疫系统). Iron helps transport oxygen in the blood, and low levels of iron can lead to feeling tired. Eating red meat, especially lean cuts(廋肉), with meals and snacks, may help people curb hunger between meals and help people with weight management.
Health risks of red meat may include the risk of heart disease and cancer. It is usually best to avoid processed meats. These tend to contain lots of salt and nitrites(亚硝酸盐), which may damage our health. Choosing lean cuts and cooking meat correctly may reduce health risks. It is generally advised not to undercook or overcook red meat and to avoid grilling(烧烤).
When it comes to red meat and health, another thing is whether the animals are grain or grass-fed. Grass-fed animals frequently have a better quality of life. Grass feeding can be more environmentally friendly as well.
Many governments suggest the amount of red meat should be safely included in a healthy diet. The amount varies between nations, but several portions a week are usually acceptable. Those who choose to include eating red meat may wish to choose grass-fed animals and to cut off any fat before eating.
