Tofu is a great source of protein. It contains carbohydrates, iron, calcium, magnesium, vitamin B1, B2, lecithin, and linoleic acid (LA) to name a few. LA is an essential fatty acid which must be obtained through diet. Consuming tofu prevents arteriosclerosis, hypertension, cardiovascular disease, and diabetes. It helps to lower LDL “bad” cholesterol from the wall of the blood vessels. Tofu also helps with digestion.
