However, the latest research by Italian scientists found that it is not worth the loss for the elderly to drink too much milk to supplement calcium, because milk will promote the occurrence of senile cataracts. The reason is that milk contains 5% lactose, which is decomposed into galactose under the action of lactase, which is easy to deposit in the lens of the eyes of the elderly and affects their normal metabolism. Moreover, protein is prone to degeneration, which leads to the decrease of lens transparency, thus leading to the occurrence of senile cataract or aggravating its condition.
Therefore, the elderly should prevent calcium deficiency and not take milk as the only source of calcium supplement. You can choose drugs such as calcium lactate, calcium gluconate and vitamin D, and you can also choose foods with high calcium content, such as dried shrimps, fish, shellfish, eggs, meat bones, kelp and snails, celery, bean products, sesame seeds, red dates, black fungus and so on. And natural food is the best.
