Warning! Eating Tofu Carelessly Can Also Lead to Poisoning
The health benefits of tofu are documented in many traditional Chinese medicine books. Recently, I've seen many tofu-based diet recipes online, such as "Four Magical Tofu Diet Plans." Some people strictly follow these diets, which I find extremely dangerous. I hope this serves as a reminder: tofu is good, but don't overindulge!
First, let's understand what makes tofu so good:
Tofu is sweet in flavor and cool in nature, with the effects of replenishing qi, harmonizing the middle jiao, promoting fluid production, and detoxifying. Modern scientific research shows that tofu's nutritional composition is 40% protein, 25% carbohydrates, and 20% fat, with 61% of the fat being polyunsaturated fatty acids. Combined with various minerals and vitamins, its nutritional value is comparable to meat, and it contains no cholesterol.
Advantage: Tofu is a "Cancer-Fighting Star"
While acknowledging the nutritional value of tofu, we must also be alert to the dangers of excessive consumption. Tofu can be a "double-edged sword." Tofu's "first face"—the "cancer-fighting star." In the last decade, many studies have found that the incidence of breast cancer, dementia, etc., is lower among Easterners. The brain tissue of dementia patients shows a decrease in lecithin concentration.
Therefore, it is speculated that Alzheimer's disease may be related to a deficiency of lecithin. And one of the best sources of lecithin is precisely the soybean.
Disadvantage: An Imbalanced Tofu Diet Can Lead to Gout or Kidney Disease
Tofu's "second face"—excessive consumption is harmful to health. Although tofu is good, overconsumption can also be detrimental to your health. The elderly and patients with kidney disease or gout should especially control their intake.
Traditional Chinese medicine considers tofu to have a cooling nature. People with a cold stomach or those prone to diarrhea may experience discomfort. Under normal circumstances, the plant protein people consume undergoes metabolic changes, and most of it eventually becomes nitrogenous waste, which is excreted by the kidneys.
As people age, the kidneys' ability to excrete waste decreases. If one doesn't pay attention to their diet and consumes a large amount of tofu, the excessive plant protein intake will inevitably increase the amount of nitrogenous waste in the body, thereby加重 the burden on the kidneys, further decline kidney function, and is not conducive to health.
The soybeans used to make tofu contain a substance called saponin. Not only can it prevent blood uric acid levels from rising, but for patients with high blood uric acid, eating too much tofu can easily trigger a gout attack.
