Recent study findings suggest that soy protein has little impact on cholesterol levels, despite recent health claims. Researchers from the American Heart Association analyzed 22 clinical trials and found that large amounts of soy protein in the diet only lowered LDL cholesterol by about 3 percent on average.
These recent findings cast doubt over claims that suggest moderate levels of soy protein have a protective effect against cholesterol levels. The review also found that soy had no impact on HDL cholesterol or blood pressure.
While further research is needed, researchers acknowledge that soy protein products such as tofu, soy nuts and some soy burgers are still considered healthy foods since they remain high in polyunsaturated fats, fiber, vitamins and minerals.
