人到老年骨与关节退行性变化占大多数,表现为骨质疏松、软化、增生等。因此,饮食营养及调护很关键,应从以下几方面进行营养保健: 一是补钙。钙质是构成骨质的主要成份,食物中钙利用好坏直接影响骨质的合成。钙的供给对老年人很重要,由于老年人消化吸收等方面的机能有所退化,又因老年人骨的代谢分解过程大于合成过程,当食物中钙含量不足,吸收钙不良则出现骨软化。为保证老年人骨质代谢正常,每月摄钙量较成人应增加50%,不应少于1200mg,食物中含钙的食物很多,自然界分布很
People to the elderly bone and joint degenerative changes accounted for the majority, manifested as osteoporosis, softening, hyperplasia and so on. Therefore, nutrition and diet is critical, should be from the following aspects of nutrition and health care: First, calcium. Calcium is the main component of the formation of bone, the use of calcium in food directly affects the quality of bone synthesis. The supply of calcium is very important for the elderly. Due to the degradation of the digestion and absorption of the elderly, the metabolic process of the bone in the elderly is greater than the synthesis process. When the content of calcium in the diet is insufficient, the calcium is absorbed and the bone is softened. In order to ensure normal bone metabolism in the elderly, monthly intake of calcium should be increased by 50% compared with adults, not less than 1200mg, food, many foods containing calcium, natural distribution is very
