In the winter, many girls are upset because of cold hands and feet. The online a message is to let the girls see the hope, the news called "iron-rich raisins also contain a variety of minerals, vitamins and amino acids, physically weak anemia of the best expert advice: eat a handful of raisins about 30-40 grams, adhere to 15 days, to improve physically weak anemia have a certain effect. "so, raisins really so magical it?
Cold hands and feet reasons, by its very nature is due to the heat of hand, feet and other extremities under-due. Heat extremities obtained mainly from two aspects, one is the organization of spontaneous heat production, on the other hand is made from the body core temperature to areas with high blood brought.
For women, because of their basal metabolism slower than men, so the body produce less heat than men. While women are generally more petite physique and limbs, large surface area, and extremities and the lack of insulation layer of fat, so more heat. At the same time, due to physiological differences and structural differences in physical activity, most women less than men arterial perfusion, resulting in less blood supply extremities. In addition, in winter, the female activity generally less than men, also resulted in lower limb blood flow and heat production. The above combined effect of these factors make women more prone to the phenomenon of cold hands and feet.
The main ingredient is actually raisins glucose, fructose and sucrose based sugars. It is a good source of calories. After eating raisins due to elevated blood sugar and thermodynamic effects of food, it can cause the body to increase metabolic rate, increase heat production, to some extent, improve the extremities of heat supply. However, other more sugar foods, supplements or even simply hot syrup can also achieve similar functionality, this effect is not specific to raisins.
In addition, the raisins to "improve physically weak anemia" no significant effect. "Physically weak" is the concept of traditional Chinese medicine, skip the talk here. For anemia, the iron deficiency anemia is the main type, but each 100 grams of raisins contains about 9.1 milligrams of iron, compared to the general food such as black fungus and bean products is not much, and therefore rely on so few raisins inside iron to achieve the "blood" the purpose of this is reluctance.
In summary, to prevent cold hands and feet, in fact, not a special ability raisins and other sugary foods more can achieve the same effect. Raisins for the "physically weak anemia" is not very helpful. Cold hands and feet to improve the situation, the best way is to do more exercise to strengthen the body's heat production and limb blood supply.
