Eating about 3 tablespoons of tahini can help your blood vessels work better within just a few hours, according to a study in healthy men.

Our analysis of the available research shows that eating about 50 grams of tahini may support better blood vessel function in healthy men. What we've found so far comes from one claim that aligns with this idea, with no evidence we've reviewed that contradicts it [1]. Specifically, the study we examined suggests that consuming roughly three tablespoons of tahini can help blood vessels work more effectively within a few hours. This is based on a single study in healthy men, and we have not yet analyzed any studies that refute this finding. To be clear, our current analysis is limited. We have reviewed one claim that supports the idea, and zero claims that refute it. That means the evidence leans toward a potential benefit, but we cannot say this is proven or definitive. More research would help us understand how consistent this effect is and whether it applies to other groups. In everyday terms, if you are a healthy man, adding a serving of tahini to your meal might give your blood vessels a short-term boost. But we have only looked at one study so far, so take this as a promising hint rather than a sure thing.
