Over the last decades, the prevalence of obesity and related diseases has increased rapidly in the modern world. Obesity is a disorder of energy balance and is associated with hyper-insulinemia, insulin resistance, and abnormalities in lipid metabolism, and it is one of the most important risk factors in the development of Type II diabetes, cardiovascular disease, atherosclerosis, and certain cancers.A diet containing soy protein may significantly reduce fat accumulation and triglycerides in the livers of obese persons, say researchers.
The positive effects of soy protein to reduce higher than normal blood cholesterol have been studied and proven in recent years. However, a study published online in Hormone and Metabolic Research showed the positive effects of soy protein isolate in obesity-related conditions such as inflammation and fatty liver disease.
Fat is metabolized in the liver, and in obese persons, the transport of fat to adipose tissue can slow down to the point that the liver becomes a dumping ground for excess fat.
Adding soy protein, in such sources as tofu and soy yogurt, appears to alleviate some of the stress on fatty livers.
Soy products help to control the cholesterol level because:
- soy is cholesterol-free
- the soy proteins reduce the cholesterol level
- most of the fats in soy products are poly-unsaturated
- soy isoflavones prevent atherosclerosis
- soy contains soluble fibers which reduces the amount of cholesterol circulating in the blood.
