Eating 50 grams of tahini (a sesame seed paste) helps lower blood sugar levels in healthy men at 1, 3, and 4 hours after a meal, and the healthy plant compounds in tahini get into the blood and become usable by the body.

The study looked at healthy men eating 50 grams of tahini and found it helped their blood sugar and antioxidant levels after meals, which matches the claim.

Consumption of sesame seeds and sesame products has favorable effects on blood glucose levels but not on insulin resistance: A systematic review and meta‐analysis of controlled clinical trials
The study looked at how eating sesame products over weeks affects fasting blood sugar, not how a single serving of tahini affects blood sugar right after a meal, so it doesn't prove the claim about the specific time points.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
