When it comes to enriching blood, everyone has different opinions. Some people say that red beans are the most blood-enriching, some people say that red flowers are the most blood-enriching, and some people say that red dates are more blood-enriching. Fat uncle tells you that these are complementary forms. Although it is red, it can't achieve the effect of enriching blood at all. Recently, Grandpa Pang noticed that "eating black beans often can replenish blood" is still circulating on the Internet. Is this statement reliable? The answer is that it is a bit difficult to simply eat black beans to replenish blood.
First of all, let's first understand what is blood supplement. It's actually quite simple. The so-called blood supplement is actually to supplement some dry goods to the blood, that is, to transport oxygen and its treasure-hemoglobin red blood cells day and night. When red blood cells and hemoglobin are sufficient, we can carry more oxygen from alveoli to our brains, organs and even every inch of skin, and provide them with oxygen in time to make them full of vitality. With enough oxygen, there will naturally be a source of strength, full of vitality and vitality, and naturally it will look younger and healthier.
How does food enrich blood? Of course, it can't be directly transformed, nor can it be shaped by shape. Specifically, it should be that the ingredients in food are absorbed and reused in the body to synthesize red blood cells and hemoglobin. Protein and iron are the most important elements in the synthesis process. Therefore, whether the effect of enriching blood can be exerted depends on whether there are these key nutrients in food.
Now, let's analyze the nutrients in black beans. The main nutritional components of black beans per100g are as follows:
Calorie: 337.0 kcal, carbohydrate: 84.2g, fat: 0. 1 g, protein: 0.5g, cellulose: 0.6g, calcium: 35.0mg, iron: 5.2mg, zinc: 0.83mg. ..
As we all know, beans are high-quality sources in protein, and black beans are really the best among beans, which can be used as a supplement to high-quality food in protein. However, the key to enriching blood lies not only in protein, but also in supplementing iron.
Generally speaking, the effect of iron supplementation should be viewed from two aspects, one is iron content, and the other is absorption. Only when both are good, can we play a better role in supplementing iron.
First of all, the iron content of black beans is twice that of spinach, but it is still not high in plant foods. Even the iron content in soybean (8.2 mg/100 g) is higher than it, not to mention dried red dates and mushrooms.
Secondly, let's look at the absorption rate. All plant foods, including black beans, have a sexual problem, that is, the form of iron belongs to non-heme iron. It doesn't matter if you don't understand. As long as you remember, the iron absorption rate of this form is very low, generally only 3%-8%, and so is black beans.
If you don't understand, let's calculate. According to the daily requirement of human body for iron 15mg (20mg for women of childbearing age), the iron content in black beans is 5.2mg, and the absorption rate is calculated according to the maximum limit of 8%. If you want to achieve the effect of enriching blood simply by eating black beans, you may need to eat 3.6kg of black beans every day (Uncle Fat is worried that his math is taught by the physical education teacher, and everyone is welcome to help with the calculation).
In that case, eating so many black beans every day is really drunk. What's more, black beans have special effects. They contain phytochemicals, such as oligosaccharides and saponin, which are especially liked by intestinal microorganisms. It is said that eating too much black beans has a good "ventilation" effect! Therefore, if the effect of iron supplementation is not achieved, it is naturally impossible to replenish blood.
To sum up, black beans, as miscellaneous grains, occupy a very important position in a reasonable diet, and there is no harm in eating them often, especially for the elderly with unstable blood sugar control. But if you want to achieve the effect of enriching blood, I am afraid it is still a little worse. It is best to eat more beef, pork or chicken, so that it will come faster and more steadily.
Uncle Pang wishes everyone a fast life, slow nutrition, balanced diet and good health!
