There is a common saying in our country that “congee for the elderly is good for longevity”, but is it true? Why have some people recently put forward the view that the elderly should not drink congee for a long time? What are they basing on? Today we will address these issues. It is reasonable to say that when people get old, the digestive system will decline, appropriate congee is conducive to digestion, more favorable to the health of the elderly. But long-term porridge will also have a negative impact on the health of the elderly, the reason is that: First, porridge without chewing, the lack of chewing will accelerate the degeneration of the chewing organs of the elderly; Second, porridge food fiber content is low, not conducive to detoxification of the elderly; Third, porridge lack of chewing, saliva in the enzyme amylase can not be porridge in the starch is fully decomposed into maltose, thus affecting digestion. Fourth, saliva and neutralize gastric acid, repair the role of gastric mucosa, porridge almost no oral secretion of saliva, naturally, is not conducive to the protection of gastric mucosa. Fifth, the elderly gastric power is poor, if you eat too much porridge, it is difficult to empty quickly, will feel upset stomach; Sixth, long-term porridge, the total calories and nutrients are not enough to get the body’s physiological needs, it is inevitable that not enough is caused by the elderly wasting. Seven, porridge soft, easy to digest, so the absorption rate is fast, the rate of blood glucose will rise too fast, especially for the elderly, the metabolic rate is not as fast as young people, the amount of exercise is not large, blood glucose is more prone to soaring, excess sugar can easily affect the function of the pancreas, stimulate the insulin, the pancreas will increase the burden on the pancreas, may damage the pancreatic islet cells, or insulin sensitivity to decline and induce diabetes. Therefore, it is not recommended that the elderly drink porridge for a long time, indigestion of middle-aged and elderly people can be used in moderation porridge, burnt, but be sure to add some coarse grains, beans or potatoes in them in moderation, at the same time encourage middle-aged and elderly people to eat more vegetables with food. Only in this way is beneficial to the health of the elderly.
