Tofu is a traditional food that is very familiar to the people. It is nutritious and rich in calcium, protein, amino acids, lecithin, and more. But did you know? There's more to tofu than meets the eye, and eating it incorrectly can be harmful to your health.

First, you should not eat too much tofu. It's best to limit your daily intake to 100-150 grams, as excessive consumption can lead to the following health problems:
1. Indigestion
Tofu is rich in protein. Consuming too much at once not only hinders the body's absorption of iron but can also lead to protein indigestion, causing discomfort such as bloating and diarrhea.
2. Promoting Kidney Function Decline
After plant protein is consumed by the body, most of it is metabolized into nitrogenous waste, which is excreted by the kidneys. If you consume large amounts of tofu and excessive plant protein over a long period, it will inevitably lead to an excess of nitrogenous waste in the body, increasing the burden on the kidneys. This is especially true for the elderly, whose kidney's ability to excrete waste may be reduced, potentially leading to a further decline in kidney function.
3. Promoting the Formation of Arteriosclerosis
There have been reports abroad that the abundant amino acids in soy products can be converted into cysteine. When ingested by the body, cysteine can damage the endothelial cells of the arterial walls, making it easier for cholesterol and triglycerides to deposit on the artery walls and promoting the formation of arteriosclerosis.
4. Triggering Gout Attacks
Tofu contains a relatively high amount of purines, which can easily cause abnormal purine metabolism in gout patients and those with elevated uric acid levels, leading to uric acid stones or gout attacks.
Second, you should pay attention to how you pair tofu to avoid the following issues:
Low Protein Utilization
The soy protein in tofu lacks one essential amino acid—methionine. If eaten alone, its protein utilization rate is low. Solution: Pair it with ingredients rich in methionine, such as fish, eggs, or meat. For example, dishes like fish head tofu, scrambled eggs with tofu, or minced meat tofu can create a more balanced amino acid profile, allowing the protein in tofu to be fully absorbed.

Causing Iodine Deficiency
Soybeans contain a substance called saponin, which can cause excessive excretion of iodine in the body. Long-term excessive consumption of tofu can easily lead to iodine deficiency. Solution: When eating tofu, don't forget to pair it with iodine-rich ingredients, such as seaweed.
Forming Stones
Tofu is very high in calcium. If it is often eaten with vegetables high in oxalic acid, it forms calcium oxalate, which is not easily absorbed and may lead to stone formation. Solution: If you want to pair tofu with high-oxalic-acid vegetables like spinach, water spinach, red amaranth, or water bamboo, be sure to blanch the vegetables first to reduce their oxalic acid content.
