How does soy affect our hearts?

Soybean products are becoming increasingly popular, but how does soy affect our health? There has been a hunch in the past that soy protein in humans can lower cholesterol, which protects against heart disease. The latest research results confirm this.

A consistent cholesterol-lowering effect for soy protein has now been found in the study by the University of Toronto. The results of the study were published in the English-language journal "Journal of the American Heart Association".

Soy protects against heart diseases

For the study, the data collected from dozens of clinical studies that spanned the past two decades were evaluated. The current investigation challenged the US Food and Drug Administration's thesis to revoke the health claim for soy protein and heart disease. The researchers were able to prove that soy generally lowers cholesterol, both total cholesterol and low-density lipoprotein cholesterol, which can damage the heart.

Plant-based nutrition increases the protective effect

The researchers performed a cumulative meta-analysis that allowed them to study the effects of soy together in all studies, but at different times and with the addition of data from each new study. The FDA will likely decide on soy health claims this summer. The data strongly support the FDA's initial statement on the impact on heart health, the researchers report. It is important to know that while cholesterol reduction was less than five percent, the effect will be much stronger if soy is included in the diet along with other plant foods.

Plant-based nutrition should be encouraged

Study author David Jenkins from the University of Toronto and his colleagues developed the so-called glycemic index in the 1980s, which shows the effect of various foods on blood sugar levels. More recently, he has helped develop a nutritional portfolio that includes nuts, vegetable protein, viscous fiber, and plant sterols, which together can reduce risk factors for heart disease by up to 30 percent. Heart UK and the European Atherosclerosis Society have included this portfolio of foods in their dietary guidelines. People are moving towards an age of vegetable protein, and it would be a shame if this change were undermined, Jenkins said. Plant-based food producers, industry and trade need every help to make their products accessible to consumers, the study author continues. (as)
