The Claim
In hypercholesterolemic adults over age 50, consumption of soy protein from any processed form (whole soybeans, soy flour, soymilk) for six weeks has no significant effect on vascular endothelial function compared to animal protein, when dietary fat, cholesterol, and fiber are held constant.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults over 50 with high cholesterol, eating soy protein for six weeks does not change vascular endothelial function compared to eating animal protein, when other dietary factors are kept the same.
See the scientific wording
In hypercholesterolemic adults over age 50, consumption of soy protein from any processed form (whole soybeans, soy flour, soymilk) for six weeks has no significant effect on vascular endothelial function compared to animal protein, when dietary fat, cholesterol, and fiber are held constant, indicating that soy protein does not improve vascular health in this population under controlled conditions.
When older adults with high cholesterol eat soy protein instead of animal protein, their blood vessels do not make more nitric oxide or use it better, so the vessels stay just as stiff and don't open wider.
What the research says
1 studyFor older adults with high cholesterol, eating soy products like tofu, soymilk, or soy flour for six weeks didn’t make their blood vessels work better than eating meat or dairy, as long as the rest of their diet stayed the same.
