Introduction: Tofu, a common food on our dining tables, is rich in nutrients. However, it should not be consumed in excess, as eating more than 100-150 grams can lead to kidney function decline, indigestion... Moreover, the way it is paired with other foods also matters. Next, let's look at some precautions for eating tofu to avoid harming your health from improper consumption.
Tofu is a traditional food very familiar to the public. 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. Promoting kidney function decline
After plant protein is ingested by the human body, most of it is metabolized into nitrogen-containing waste, which is excreted by the kidneys. If you consume large amounts of tofu for a long time, you will inevitably take in excessive plant protein, leading to an excess of nitrogen-containing waste in the body and increasing the burden on the kidneys. This is especially true for the elderly, whose kidneys have a reduced ability to excrete waste, as their kidney function may further decline.
2. Promoting the formation of arteriosclerosis
There have been reports abroad that the rich amino acids in soy products can be converted into cysteine. After being ingested by the human body, it can damage the endothelial cells of the arterial wall, making it easy for cholesterol and triglycerides to deposit on the arterial wall and promoting the formation of arteriosclerosis.
3. Indigestion
Tofu is rich in protein. Consuming too much at once not only hinders the body's absorption of iron but can also easily lead to protein indigestion, causing discomfort symptoms such as bloating and diarrhea.
4. Triggering gout attacks
Tofu contains a relatively high amount of purines, which can easily cause uric acid stones or gout attacks in patients with abnormal purine metabolism or elevated blood uric acid levels.
Second, you should also pay attention to pairing tofu with other foods to avoid the following issues:
Low protein utilization rate
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, and meat. For example, dishes like braised tofu with fish head, scrambled eggs with tofu, or tofu with minced meat can balance the amino acid profile and help the body fully absorb the protein in tofu.
Causing iodine deficiency
Soybeans contain a substance called saponin, which can cause excessive excretion of iodine in the human 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 high in calcium. If often eaten with vegetables high in oxalic acid, it will form calcium oxalate, which is not easily absorbed, and may lead to stone formation.
Solution: If you want to pair tofu with vegetables high in oxalic acid, such as spinach, water spinach, red amaranth, or water bamboo, be sure to blanch the vegetables first to reduce their oxalic acid content.
