Despite a smell like rotting garbage, stinky tofu offers great flavor and multiple health benefits to aficionados. Stinky tofu is tofu that has been soaked in a brine made from fermented vegetables. The brine might also contain dried shrimp, greens, bamboo shoots and herbs – enhancing its stinkiness. Stinky tofu provides the nutritional qualities of regular tofu and the benefits of healthy bacteria created with fermentation.
Stinky tofu is a popular street food in Taiwan, Indonesia and China. It is sometimes fried, served with a sweet and spicy sauce, sautéed or served without any embellishment as a side dish. Cubes of tofu are marinated in the smelly brine for several days, weeks or months. Stinky tofu is only available in certain regions and specialty markets in the United States.
Tofu is a vegan source of protein that is low in fat. You can use it to replace animal-based proteins that contain higher amounts of artery-clogging saturated fats. Eating tofu instead of meat laden with saturated fat can help reduce cholesterol levels. Tofu is made from soybeans, which might help reduce your incidence of breast and prostate cancer – but studies are inconclusive. Soy foods might also help ease the symptoms of menopause.
Fermenting the tofu creates healthy bacteria, called probiotics, which help populate the gut and improve digestion. In the United States, yogurt is one of the most common sources of probiotics, but if you can stomach the smell of stinky tofu, it can offer similar healthy bacterial benefits. Like natto -- a mashed, cheese-like soybean-fermented food -- stinky tofu might also confer antioxidant benefits. Antioxidants help fight disease-causing free radicals in the body.
The January 2010 issue of “Nutrition Research” published a review finding that consumption of fermented soybean products might help prevent or at least delay the progression of type 2 diabetes, compared with consumption of nonfermented soybeans. Studies performed on animals and humans found that certain isoflavonoids and bioactive peptides, or specific plant compounds, form during fermentation and these might reduce insulin resistance and boost insulin secretion.
