What foods detoxify and slim down? Pig blood contains iron, zinc, calcium, manganese, copper and other minerals, of which the iron content is as high as 45 mg, and the iron content of cattle, sheep, pigs and fish is only 0.4-5 mg. The main function of meat and eggs is to provide people with high-quality protein. The high-quality protein content of pig blood is equivalent to that of meat and eggs, but it does not have the disadvantage that meat contains a lot of fat.

Mineral iron is an essential raw material for hematopoiesis. Iron in pig blood is heme iron, which is not only higher than any other food, but also easily absorbed by human body, and the absorption rate in small intestine can reach 37%.

If they eat 20 grams of pig blood every day, they can basically make up their daily demand for iron, and they can avoid and correct it.
In addition, pig blood also has the functions of removing dirt, relaxing bowels and moistening intestines. The plasma protein in pig blood is digested and decomposed in the intestine, and beneficial components such as heme iron are absorbed in the intestine. At the same time, the remaining residues can also absorb harmful substances in the intestine, such as metal particles and dust that enter the digestive tract with food, and transform them into feces, which are directly discharged from the body, thus avoiding the harm caused by these substances to people. Because heme iron can not be completely absorbed by human body, the rest turns black under the action of gastric acid and digestive enzymes, so the feces are tar-like. Eat more than 30-50 grams of pig blood at a time, and the stool will not be secret. Therefore, elderly people who are prone to constipation can achieve the purpose of clearing intestines and detoxifying by eating pig blood.
