A recent study has reviewed 10 years of available data from randomized controlled trials regarding the beneficial effects of soya proteins on serum lipid profiles. The review study found that a significant reduction in serum LDL-cholesterol and total cholesterol was achieved with increased intake of soya products. In addition, the study reported significant increases in serum HDL-cholesterol with increasing soya intake. The review reported greater reductions in LDL cholesterol with intake of ‘whole’ soya products, such as soya milk and soya beans, compared with processed food containing soya extracts.
