summary

The older the elderly are, the more they can't stand the hardship. They always suffer from various diseases due to the lack of calcium, zinc and other trace elements. Generally, what are the symptoms and manifestations of zinc deficiency in the elderly? Now let's take a look.

What symptom does old people lack zinc to have

First: the symptoms and manifestations of zinc deficiency in the elderly, if the elderly often feel abnormal taste, food is not fragrant, no appetite. That may be due to zinc deficiency. This is because zinc participates in the synthesis of gustatory hormone, which can enhance the sensitivity of taste buds and promote appetite.

Zinc is closely related to the body's immune function. The decline of immune function is one of the important manifestations of aging. It is also the reason why the elderly are prone to infectious diseases and tumors. Clinical observation shows that zinc deficiency can cause thymus atrophy, decrease of blood lymphocytes, decrease of natural killer cell function and decrease of cellular immune function, while zinc supplement can enhance immune function. 2.2. Zinc has the function of antioxidant. Free radical damage is an important factor to promote aging. The ability of scavenging free radicals in the elderly is weakened correspondingly. Free radicals cause lipid peroxidation, form lipid peroxide (LPO), destroy the biofilm, and lead to cell death. Zinc has antioxidant activity and can protect the structure and function of biofilm.

Third: how to supplement zinc for the elderly? Zinc has antioxidant effect in the body and shows anti-aging effect. At the same time, it also plays a certain role in the prevention of some senile diseases. Zinc supplement mainly depends on intake from food. All kinds of animal and plant foods contain zinc. As long as the elderly pay attention to the diet structure, there is generally no zinc deficiency. However, because there are more vegetable acids in all kinds of vegetables, it can form complex with zinc, thus hindering the absorption of zinc (people who mainly eat plant-based food are prone to zinc deficiency). Some elderly people like to eat light diet, eat less animal food, and the absorption function is poor, so they are prone to zinc deficiency. Therefore, the elderly should pay attention to a balanced diet and eat an appropriate amount of animal food, such as mushun, clams, pork, beef, mutton, poultry, eggs, dairy products, animal liver, etc. the zinc content in the food is high and easy to be absorbed by the human body, which is beneficial to the health of the elderly. When zinc deficiency occurs due to various reasons, active treatment should be carried out and drugs such as zinc gluconate tablets should be taken in time according to the doctor's advice.
