Tofu has high nutritional value and is a cheap and high-quality source in protein. According to legend, tofu was invented by Liu An, an alchemist in the Han Dynasty and the king of Huainan, which provided a very high-quality protein for our race. Like long-term vegetarians, their protein needs are often met by tofu. Tofu is rich in high-quality protein, soybean phospholipids, unsaturated fatty acids, phytosterols, various minerals and vitamins. It is indeed a very healthy food, and it is also an important food source for obtaining high-quality protein in the diet.

When soybean is washed, soaked, ground and pickled to make tofu, its purine content will basically be reduced to about 20 mg. This is a standard low-purine food, of course, it is edible, as long as it is not eaten too much, there is no problem.

Tofu is rich in plant protein, dietary fiber, unsaturated fatty acids, calcium, potassium, zinc, selenium and other nutrients, which is an important part of a balanced diet. Calcium helps to maintain bone health, potassium helps to lower blood pressure, unsaturated fatty acids help cardiovascular health, plant protein helps to promote muscle growth, and tofu can supplement protein and calcium. As we all know, tofu is a bean product made by adding magnesium chloride, gypsum or gluconic acid δ -lactone after soybean is processed into soybean milk. After soybean is made into tofu, the digestibility of protein can be increased from 65% to over 80%, which is better than soybean.

Many reports on the internet say that patients with tofu gout can't eat it, but it's not absolutely impossible. The purine content of soybean is very high, but after dilution and yellow slurry extrusion, the purine content of tofu drops rapidly, which belongs to medium purine food, so gout patients can eat it, but they must eat less. The main component of tofu is methionine. Methionine will ferment into cysteine under the action of enzymes. At the same time, it will also cause large and small damage to endothelial cells in the arterial wall, so that cholesterol and triglycerides will accumulate on the arterial wall. Eating tofu often can easily cause arteriosclerosis.
