Tofu is a soy product that we often eat in our daily lives. It is rich in trace elements, carbohydrates, high-quality protein, and is known as "plant meat". Traditional Chinese medicine points out that tofu is sweet in taste and cool in nature, which can promote the production of body fluids, moisten dryness, replenish qi, and harmonize the middle. It also has effects such as detoxifying from sulfur and alcohol. Since tofu is so nutritious, why do some people say that eating tofu can be harmful to the elderly? The editor will explain this in detail below:
One, leading to kidney function decline
Under normal circumstances, the plant protein that enters the human body is mostly converted into nitrogenous waste after metabolism, which is excreted by the kidneys. However, the kidney function of the elderly and some patients with kidney disease declines. If they consume excessive amounts of tofu, it will加重 the burden on the kidneys, leading to a decline in kidney function, thus affecting their health.
Two, causing indigestion
Tofu contains extremely rich protein. Once consumed in excess, these proteins will accumulate in the body, causing indigestion, leading to discomfort symptoms such as bloating and diarrhea.
Three, causing iodine deficiency disease
Tofu contains a substance called saponin, which can promote the excretion of iodine in the human body. Therefore, if people eat tofu for a long time, it is easy to cause a large loss of iodine in the body, leading to iodine deficiency disease. Of course, the above problems do not advocate that the elderly should stay away from tofu. Eating it in moderation will not have a great impact on the health of the elderly.
Four, triggering gout
Tofu contains a high amount of purine substances. The abnormal metabolism of purine is the key cause of gout. Therefore, when gout patients consume excessive tofu, it is easy to trigger a gout attack.
Five, causing arteriosclerosis
Tofu contains extremely rich methionine. After entering the human body, methionine is converted into cysteine under the action of enzymes. Cysteine can damage the endothelial cells of the arterial wall, causing cholesterol and triglycerides to deposit on the arterial wall, leading to arteriosclerosis.
The above is the editor's detailed introduction to why eating tofu affects the health of the elderly. Eating tofu in moderation will not affect the health of the elderly, so we should pay attention to it in our daily diet.
