Tahini has quietly become a pantry staple, folded into hummus, drizzled over roasted vegetables and stirred into salad dressings. New evidence suggests the sesame paste may do more for the heart than lend a nutty flavor. A 2024 meta-analysis of 13 randomized trials with 731 participants found that daily sesame supplementation, including tahini, was linked to a mean drop of 29.72 mg/dL in LDL cholesterol and 32.76 mg/dL in total cholesterol compared with controls.
Participants in those trials took sesame products daily for six to twelve weeks. The doses fell within a range many home cooks already work into a bowl of hummus or a lemon-tahini dressing.
One caveat up front. Nearly all of the trials in the meta-analysis enrolled patients with type 2 diabetes, whose baseline cholesterol tends to run high. The size of the drop is likely smaller for people who start out with healthier numbers, though the direction of the effect is consistent with what smaller studies in the general population have shown.
What tahini brings to the plate
A two-tablespoon serving of tahini delivers about 178 calories, 16 grams of fat and 5 grams of protein, according to a nutritional breakdown by Medical News Today. Only 2 of those 16 grams are saturated. The rest are the monounsaturated and polyunsaturated fats that lower LDL when they replace saturated fat in the diet.

Sesame is also unusually rich in phytosterols, plant compounds that behave like cholesterol and block some of the cholesterol from food being absorbed in the gut. In a comparison of 27 different nuts and seeds, sesame ranked at the top for phytosterol content, ahead of pistachios and sunflower seeds.
A single serving already moves the needle
The effects begin well before six weeks. In a small trial published in the Journal of Human Hypertension, 20 healthy men with an average age of 28 ate 50 grams of tahini after an overnight fast. Diastolic blood pressure and pulse rate both fell four hours after the meal, and endothelial function, a measure of how well the inner lining of the arteries expands, improved.
A separate study from the same Athens-based research group, published in Atherosclerosis in 2022, tracked antioxidant markers in the blood after the same tahini dose and found a rise in plasma antioxidant capacity within the first hour.
Both trials were small and limited to healthy young men, so they say more about mechanism than about long-term protection. They line up, though, with the pattern in the larger cholesterol data. Sesame appears to nudge several cardiovascular markers in the right direction at once.

How to work it into a normal week
The doses used in the trials, roughly two to four tablespoons a day, fit comfortably into ordinary meals. Blend tahini into hummus, whisk it with lemon juice and garlic for a salad dressing, spread it thin on toast under sliced fruit, or spoon it over roasted eggplant or grain bowls. Portion still matters, because a serving carries close to 180 calories.
Readers who want to see where their own numbers sit can look up normal ranges for LDL, HDL and total cholesterol by age. Anyone already on a statin or diagnosed with a lipid disorder should talk to a doctor before making tahini a daily habit, since dietary changes can shift how well cholesterol medications work.
The U.S. Dietary Guidelines already advise replacing saturated fats with plant-based unsaturated ones. At about 14 grams of unsaturated fat per two-tablespoon serving, tahini is one of the more concentrated ways to make that swap at breakfast, lunch or dinner.
