Health Benefits of Tofu
The health benefits of tofu include its ability to help lower cholesterol levels, prevent anemia and manage weight, among others.
Lowers Cholesterol Level
Consuming tofu reduces the cholesterol level in the body. Additionally, using it as an alternative to the animal protein can help lower LDL (bad) cholesterol in the body. As compared to meats such as beef, it has lower levels of saturated fatty acids and higher levels of unsaturated fatty acids. It is also a good source of lecithin and linoleic acid, which helps regulate the metabolism, along with the dispersion and elimination of cholesterol deposits in the body.
Maintains Cardiovascular Health
Tofu helps reduce the risk of cardiovascular diseases. Regular consumption of soy products may lower the levels of saturated fats along with cholesterol levels in the body. A report in the Food and Agriculture Organization of the United Nations says that tofu has a low sodium content, which makes it good for people with high blood pressure.
Intake of tofu also aids in managing weight effectively. A study done in China suggests that soy-based low-calorie diets have a beneficial effect on the reduction of weight and blood lipids.
Eases Menopause Symptoms
The organic compounds in tofu, namely isoflavones, are instrumental in managing the symptoms of menopause in women. Isoflavones are plant-based compounds that mimic the estrogen hormone in the body. It can help stabilize the estrogen levels during menopause and relieve hot flashes.
The isoflavones in tofu are known to be beneficial in reducing the risk of different types of cancer (Uifalean A et al., 2018). Research published in the Journal of the National Cancer Institute 2012 suggests that a higher intake of products such as tofu helps prevent endometrial cancer in post-menopausal women. It has also been associated with a reduction in breast, lung, and prostate cancer.
Tofu is a rich source of calcium, which is the key ingredient in bone formation. This is why the intake of tofu is highly recommended. Lack of calcium in the body could lead to osteoporosis, especially in old age. Consuming it slows down the entire process by keeping the bones strong.
Helps Manage Diabetes
Treats Kidney Diseases
Tofu, being an excellent source of iron, can help prevent anemia. Deficiency of iron causes a drop in the number of healthy red blood cells leading to anemia. A study conducted in China also showed that tofu helped lower the risk of anemia among adults.
Tofu curdled with various coagulants helps prevent liver damage caused due to oxidative stress.
Tofu is also known to improve memory and cognitive function for women above 65-years age. The lecithin content present in it helps the body produce the phospholipids phosphatidic acid (PA) and phosphatidylserine (PS), which aid in the normal functioning of the neurons.
People use tofu to prevent hair loss issues as it provides keratin, a protein essential for hair growth. So, dump those expensive hair treatments and add it to your diet.
Rich in Protein
Tofu, other soy products, and vegetables are a great source of protein for vegans and vegetarians. They also provide the required amino acids, which are beneficial for maintaining optimal health.
Research on tofu suggests that it is a preferable source of protein, especially for gout patients with uric acid clearance more than the lower normal limit. However, they are advised to avoid excess intake of it.
- Gut damage: Majority of soy-products including tofu available in the market are genetically modified. Genetically modified tofu can cause kidney stone, digestive problems, and liver issues too. These GMO products pose many risks to human health as they kill the good bacteria in the gut.
- Thyroid issue: According to a report, infants who are fed soy-diet are more susceptible to thyroid problems, especially those that are born with congenital hypothyroidism. Therefore, those suffering from hypothyroidism are advised to avoid consumption of soy-bean and soy-products.
- Breast tumor: The phytoestrogen present in this soy variety acts like estrogen hormone. When it is consumed in excess, it blocks the natural production of estrogen in the body. Therefore, those women who have a family history of breast cancer and those who are currently battling breast cancer should avoid consuming it.
- Food allergy: Some people may experience allergic reactions. So avoid intake in case you are allergic to soy products.
