1, causing indigestion
Beans contain rich and colorful proteins. Too much intake at one time not only hinders the digestion and absorption of iron, but also is very prone to abdominal distension, diarrhea and other diseases.
2, improve the pressure of renal function
Under all normal conditions, people's intake of green plant protein in the body undergoes metabolism, and eventually most of it becomes medium nitrogen waste, which is discharged from the body by kidney function.
When people come to the elderly, the function of renal function metabolic waste is reduced. At this time, if we don't pay attention to healthy diet, many people will take tofu and take too much natural plant protein, which will definitely increase the amount of nitrogen waste converted by the body, aggravate the pressure of renal function and be detrimental to physical and mental health.
3, promote the generation of arteriosclerosis
Bean food contains extremely rich and colorful methionine, which can be converted into cysteamine under hydrolysis. Cysteamine can damage endothelial cells of aortic wall thickness, easily accumulate cholesterol and triglycerides on the inner wall of aorta, and promote arteriosclerosis.
The substance with saponin in soybean can not only prevent atherosclerosis of main artery, but also continue to accelerate the metabolism of iodine in the body. Long-term excessive use of tofu is very easy to cause iodine deficiency, resulting in iodine deficiency.
5, promote gout attack
Water tofu contains more purines, and hyperuricemia patients with disordered purine metabolism and patients with increased blood uric acid concentration are prone to gout attacks, especially patients with hyperuricemia should eat less.
1, put vegetables and black fungus to prevent diseases.
Although water tofu is rich in nutrition, it lacks dietary fibres, so eating it alone may cause constipation. And vegetables and auricularia auricula have colorful dietary fibres, which can just fill this defect of tofu.
In addition, auricularia auricula and vegetables also contain many antioxidant components that can enhance immunity and prevent infectious diseases. When taken with tofu, the disease resistance is stronger.
It should be noted that the oxalic acid content in green leafy vegetables such as broccoli and shepherd's purse is high. You should blanch it first, and then cook it with tofu to prevent it from affecting the digestion and absorption of calcium in tofu.
