Health Canada’s Food Directorate approved a ‘Health claim about Soy Protein and Cholesterol Lowering’ (23 april 2015). According to Health Canada’s Food Directorate, scientific evidence exists to support the health claim that consumption of soy protein helps to lower blood cholesterol levels.
The Health Canada’s Food Directorate based its decision on literature research covering a period from 1980 to March 2010.
The Health Canada’s Food Directorate considered that all foods containing soy protein such as isolated soy protein, soy protein concentrate, textured soy protein and soy flour but also soyfoods made from the whole soybean are eligible for the health claim. Food containing at least 6g of soy protein per reference amount and per serving as well as complying with a list of conditions regarding the presence of recommended nutrients, maximum levels of cholesterol, alcohol, etc., are allowed to bear the health claim.
The evidence consistently supports a direction of effect towards a reduction in total and LDL cholesterol levels when soy protein is consumed. A meta-analysis showed a statistically significant reduction in total and LDL cholesterol levels with soy protein consumption and no detrimental effect on HDL cholesterol and triglyceride levels.
Health Canada’s Food Directorate has concluded that scientific evidence exists to support a claim about soy protein and blood cholesterol lowering.
Moreover soyfoods are low in saturated fat and low saturated fat foods are beneficial in maintaining healthy blood cholesterol levels.
