Many people think that fruit is healthy, can beautify the face and help anemia. More people think that grapes and cherries are rich in iron, so you don't have to worry about cholesterol and calories when you supplement iron with fruits. But are these "concepts" really correct?

If you want to "enrich the blood" by supplementing iron, nutritionist Cheng Hanyu said that the best way is to start with animal food. The redder the meat or viscera, the higher the iron content, and the average absorption rate is 20-30%. Although vegetables and cereal plants contain high iron content, the absorption rate is only 5%, and plant foods contain more phytic acid and fiber, which will affect the human body's absorption of iron. In addition, due to the lack of meat protein factors, they can not help the small intestine absorb iron. Therefore, when eating plant food with high iron content, it can be eaten with a small amount of meat to increase the iron absorption rate.

Although pig liver is not only effective in enriching blood, but also rich in vitamins A and D, due to the high content of sodium, protein, cholesterol and purine in pig liver, Cheng Hanyu suggested that it should be eaten 1 time per week, and the consumption per time is about 105g, about 7 pieces of pig liver. Because the upper limit of cholesterol intake is 300 mg per day, the cholesterol content of 105 g pig liver reaches 273.
