The Claim
The consumption of differently processed soy-based products and different types of protein (animal and soy) has no clinically significant effect on cardiovascular disease risk factors, including peripheral endothelial function, in hypercholesterolemic adults when other major dietary variables 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 with high cholesterol, eating soy protein or animal protein does not change measures of heart health such as blood vessel function, as long as other dietary factors remain the same.
See the scientific wording
The consumption of differently processed soy-based products and different types of protein (animal and soy) has little clinical effect on cardiovascular disease risk factors, including peripheral endothelial function, when other major dietary variables are held constant, suggesting that soy protein alone is not a potent intervention for reducing cardiovascular risk in hypercholesterolemic adults.
When people with high cholesterol eat soy protein instead of animal protein, their blood vessels do not change how they relax or how much nitric oxide they produce, so blood flow and pressure stay the same.
What the research says
1 studyWhen people with high cholesterol switched from meat and dairy to different kinds of soy foods, their heart health markers barely changed—except for a tiny drop in bad cholesterol from soymilk, which wasn't enough to matter. So, soy protein alone doesn't strongly improve heart health when the rest of the diet stays the same.
