Evaluation of the health benefits of soy protein consumption in the metabolic syndrome: focus on visceral adipose accumulation and plasma subclasses.
Nutritional approaches for the primary prevention of cardiovascular diseases, currently the commonest cause of death worldwide, is, generally-speaking, a well-established strategy. Different food products, like plant-based foods and especially soy foods appear to be appropriate to contribute to this goal.
The aim of this 12-week intervention study was to assess the cardio-metabolic effects of a diet with
soy foods corresponding to 30g soy protein per day. Soy foods corresponding to 30g of soy protein per day were given to individuals with moderate metabolic syndrome (n=26) in substitution of animal foods containing the same protein amount. A parallel control group (n=27) followed a standard a lipid-lowering diet.
Soy intervention resulted in a reduction in several metabolic syndrome features. Moreover, in the soy group we observed a significant improvement of median percentage changes for body weight (-1.5 %) and body mass index (-1.5 %), and for atherogenic lipid markers, like total cholesterol (-4.85 %), LDL-cholesterol (-5.25 %), non-HDL-cholesterol (-7.14 %) and apolipoproteinB (-14.8 %).
In conclusion, 30g soy protein per day in a lipid lowering diet significantly improved a relevant set
of biomarkers associated with cardiovascular and metabolic risk.
