中国中老年人的营养现状:普遍缺乏维生素A、维生素B2、钙、锌和硒。另外,在全国调查中发现,有的地区患缺铁性贫血的老年人仍高达40％,所以补铁也是必要的。相反,脂肪、胆固醇的摄取则显得过多。中老年人营养不平衡是造成中老年疾病的重要原因。中国中老年人不缺铜、碘、镁、维生素B12,尤其是磷的摄入量过高这也是造成我国中老人钙流失严重的原因之一。 Nutritional status of middle-aged and elderly people in China: Vitamin A, vitamin B2, calcium, zinc and selenium are generally lacking. In addition, the national survey found that iron deficiency anemia in some areas is still up to 40% of the elderly, so iron supplementation is also necessary. In contrast, fat, cholesterol intake is too much. Middle-aged and elderly nutrition imbalance is caused by an important reason for the disease. Chinese elderly do not lack copper, iodine, magnesium, vitamin B12, especially phosphorus intake is too high, which is also caused by the loss of calcium in the elderly one of the reasons.
