A scene often seen in movies or dramas is the act of feeding tofu to someone who has been released from incarceration. This action, feeding pure white tofu symbolizing purity, is interpreted as meaning "never commit a sin again." However, there are also nutritional reasons behind this tradition.
In the past, the diet provided in prisons differed from today's standards, and solely relying on such diets often led to nutritional imbalances. Therefore, many former inmates would find themselves in poor health upon release. Feeding tofu, a health food, to replenish their strength, is believed to have originated from the need to address this issue.
Tofu has long been recognized as a healthful food. It is a high-protein food, and protein is known to be a major component of immune cells and enzymes that regulate metabolic activity in the body. While regular beans have tough fibers that hinder protein absorption in the body, tofu has an absorption rate of up to 95%. Additionally, tofu is rich in calcium. The coagulant used in making tofu is responsible for these characteristics. In fact, half a block (200g) of tofu contains more calcium than a pack (200g) of milk.
However, there are precautions to consider when consuming tofu. People with anemia or heart disease may experience interference in the absorption of minerals such as iron and zinc due to a substance called phytic acid found in tofu. Therefore, it's advisable for anemia patients or those with heart disease not to excessively consume beans or tofu. Especially for individuals with heart disease, excessive intake of high-protein foods can lead to the production of ammonia, which can burden the heart.
The tradition of feeding tofu to former inmates can be understood not only as a symbolic gesture but also for nutritional reasons. However, it's important for each individual to maintain appropriate dietary habits according to their situation and health status. Wishing you a healthier and happier life through healthy eating habits and proper nutrition.
