Does eating 50g of tahini with bread improve blood vessel function in people with well-controlled type 2 diabetes?
What the Evidence Shows
What we've found so far is that the evidence on whether eating 50g of tahini with bread improves blood vessel function in people with well-controlled type 2 diabetes is split. Our analysis of the available research shows two claims, but they present opposing views based on the same numerical evidence, which we cannot explain further.
One claim suggests that consuming 50g of tahini with two slices of bread might support better blood vessel function for a few hours in people with well-managed type 2 diabetes, and this is listed as having 46.0 supporting studies . However, the second claim states that eating a sandwich with 50g of tahini may give a temporary boost in blood vessel health in the same group, yet this is listed as having 46.0 refuting studies [2]. We cannot reconcile why the same quantity and context of tahini intake appears in both supporting and refuting categories based on the data provided.
Because the evidence we’ve reviewed shows equal numerical support and opposition—46.0 on each side—we cannot determine a clear direction. We also cannot verify the quality, design, or origins of these studies, as they are not described beyond their count.
Our current analysis does not allow us to say whether this effect is likely or unlikely. The numbers appear contradictory, and without more detail, we can’t assess consistency, strength, or reliability.
In everyday terms, this means that based on what we’ve reviewed so far, we don’t have a clear picture of whether adding 50g of tahini to bread helps or doesn’t help blood vessel function in people with well-controlled type 2 diabetes. More transparent and complete evidence would be needed to better understand this.
