What should the elderly pay attention to when eating in winter if they are afraid of the cold?

　　The research found that elderly The ability to regulate or maintain body temperature in cold environments is related to how much iron they consume daily in their diet. Therefore, experts remind the elderly to eat more iron-rich foods in winter, such as black fungus, kelp, seaweed, soy products, pork liver, lean meat, eggs, etc.

　　At the same time, studies have shown that drinking tea can affect the absorption of iron. After the iron in food passes through the gastric juice, high-priced iron can be absorbed by the body only after it is quickly converted into low-priced iron. Tea contains a large amount of tannic acid, which easily combines with low-priced iron to form an insoluble tannic acid, thereby hindering the absorption of iron and causing anemia The condition worsens.

　　Drinking tea with a meal can reduce iron absorption by 60%. coffee It will be reduced by 40%. The iron contained in fruits, vegetables and cereals is more easily absorbed by the body if taken together with vitamin C. Therefore, doctors suggest that while eating a meal, the elderly may wish to drink a glass of juice or take 100 mg of vitamin C, which can quadruple the amount of non-blood iron absorbed by the body.
