课文(二):骨头汤助我们补钙

人体的骨骼由有机质无机盐两大类成分组成。其中有机质主要是胶原蛋白,其功能是使骨头具有弹性;而无机盐主要有,可以使骨质坚固。

所以,民间认为“多喝骨头汤能帮助补钙”,是有一定道理的。骨胶原能帮助钙质有效地沉积在骨骼上,提高钙的吸收利用率。骨头汤富含钙和骨胶原,无疑成为补钙的途径之一。

另外,骨头汤含有丰富的磷,钙的吸收利用也需要有一定比例的磷才能完成,单吃钙片补钙就有缺磷的弊病。

不过,单纯地认为“只喝骨头汤就能补钙”的想法,就不是科学的态度了。测定结果显示,骨头汤里的钙含量并不像我们想象的那么高,同时骨头汤里也缺少促进钙吸收的维生素D。

有人测算,用1公斤肉骨头煮汤2小时,汤中的含钙量在20毫克左右,一小碗猪骨头汤中所含钙量仅有2毫克,与更年期妇女每日所需1000毫克以上的钙量相去甚远。如果仅靠喝汤来补钙,那至少每天要喝几百碗骨头汤,显然这不现实。而普通成年人每日需要的钙推荐摄入量也要有800毫克,骨折的病人需要的钙就更多了。

所以喝骨头汤也不能迷信,想积极补钙还要在日常饮食中多注意奶类、豆制品的摄入。

Text (2): bone soup helps us supplement calcium

The human skeleton consists of two major components, organic matter and inorganic salts. The organic matter is mainly collagen, whose function is to make the bone elastic. Inorganic salts mainly include calcium and phosphorus which can make bones firm.

Therefore, people believe that “drinking more bone soup can help supplement calcium” which is reasonable. Bone collagen can help calcium to be effectively deposited on bones and improve the absorption and utilization rate of calcium. Bone soup is rich in calcium and bone collagen, undoubtedly it is one of the ways of calcium enrichment.

In addition, bone soup is rich in phosphorus, the absorption and utilization of calcium also need to have a certain proportion of phosphorus to complete the cycle. Eating calcium tablets alone may have the disadvantage of phosphorus deficiency.

However, simply thinking that “only drinking bone soup can increase calcium” idea, is not a scientific attitude. The results showed that the calcium content in the bone soup was not as high as we imagined, and there was also a lack of vitamin D to promote calcium absorption in the bone soup.

Some people calculate that when one kilogram of meat and bone is used to cook a soup for two hours, the calcium content in the soup is about 20 mg, and the calcium content in a small bowl of pig bone soup is only 2 mg, which is far from the amount of 1,000 mg needed by climacteric women each day. If a person only drinks soup to supplement calcium, then at least every day they need to drink hundreds of bowls of bone soup, obviously, this is not realistic. The recommended daily intake of calcium for ordinary adults is 800 mg, and patients with bone fractures need even more calcium.

Therefore, the belief in drinking bone soup alone cannot be blindly followed. If a person wants to actively supplement calcium in the daily diet they should also pay more attention to the intake of milk and soy products.
