Sesame seeds are tiny, oil-rich seeds that grow in pods on the Sesamum indicum plant.
Unhulled seeds have the outer, edible husk intact, while hulled seeds come without the husk.
The hull gives the seeds a golden-brown hue. Hulled seeds have an off-white color but turn brown when roasted.
Sesame seeds have many potential health benefits and have been used in folk medicine for thousands of years. They may protect against heart disease, diabetes, and arthritis.
However, you may need to eat significant amounts — a small handful per day — to gain health benefits.
Here are 15 health benefits of sesame seeds.
1. Sesame seeds are good sources of fiber
Three tablespoons (30 grams) of unhulled sesame seeds provide 3.5 grams of fiber, which is 12% of the recommended daily intake (RDI).
Since the average fiber intake in the United States is only half of the RDI, eating sesame seeds regularly could help increase your fiber intake.
Fiber is well known for supporting digestive health. Additionally, growing evidence suggests that fiber may play a role in reducing your risk of heart disease, certain cancers, obesity, and type 2 diabetes.
Summary: A 3-tablespoon (30-gram) serving of sesame seeds supplies 12% of the RDI for fiber, which is vital for your digestive health.
2. Sesame seeds may lower cholesterol and triglycerides
Some studies suggest that regularly eating sesame seeds may help decrease high cholesterol and triglycerides — which are risk factors for heart disease.
Sesame seeds consist of 15% saturated fat, 41% polyunsaturated fat, and 39% monounsaturated fat.
Research indicates that eating more polyunsaturated and monounsaturated fat relative to saturated fat may help lower your cholesterol and reduce heart disease risk.
What’s more, sesame seeds contain two types of plant compounds — lignans and phytosterols — that may also have cholesterol-lowering effects.
When 38 people with high blood lipids ate 5 tablespoons (40 grams) of hulled sesame seeds daily for 2 months, they experienced a 10% reduction in “bad” LDL cholesterol and an 8% reduction in triglycerides compared to the placebo group.
Summary: Sesame seeds may help reduce heart disease risk factors, including elevated triglyceride and “bad” LDL cholesterol levels.
3. Sesame seeds are a nutritious source of plant protein
Sesame seeds supply 5 grams of protein per 3-tablespoon (30-gram) serving.
To maximize protein availability, opt for hulled, roasted sesame seeds. The hulling and roasting processes reduce oxalates and phytates — compounds that hamper your digestion and absorption of protein.
Protein is essential for your health, as it helps build everything from muscles to hormones.
Notably, sesame seeds are low in lysine, an essential amino acid more abundant in animal products. However, vegans and vegetarians can compensate by consuming high-lysine plant proteins — particularly legumes, such as kidney beans and chickpeas.
On the other hand, sesame seeds are high in methionine and cysteine, two amino acids that legumes don’t provide in large amounts.
Summary: Sesame seeds — particularly hulled ones — are a good source of protein, which is a necessary building block for your body.
4. Sesame seeds may help lower blood pressure
High blood pressure is a major risk factor for heart disease and stroke.
Additionally, lignans, vitamin E, and other antioxidants in sesame seeds may help prevent plaque buildup in your arteries, potentially maintaining healthy blood pressure.

In one study, people with high blood pressure consumed 2.5 grams of powdered, black sesame seeds — a less common variety — in capsule form every day.
At the end of one month, they experienced a 6% decrease in systolic blood pressure — the top number of blood pressure readings — compared to the placebo group.
Summary: Sesame seeds are high in magnesium, which may help lower blood pressure. Additionally, their antioxidants may help prevent plaque buildup.
5. Sesame seeds may support healthy bones
Sesame seeds — both unhulled and hulled — are rich in several nutrients that boost bone health, though the calcium is mainly in the hull.
Three tablespoons (30 grams) of sesame seeds boast:
- Calcium: 22% of your daily need
- Magnesium: 25% of your daily need
- Manganese: 32% of your daily need
- Zinc: 21% of your daily need
However, sesame seeds contain natural compounds called oxalates and phytates, antinutrients that reduce the absorption of these minerals.
To limit these compounds’ impact, try soaking, roasting, or sprouting the seeds.
One study found that sprouting reduced phytate and oxalate concentration by about 50% in both hulled and unhulled sesame seeds.
Summary: Unhulled sesame seeds are especially rich in nutrients vital to bone health, including calcium. Soaking, roasting, or sprouting sesame seeds can improve the absorption of these minerals.
6. Sesame seeds may reduce inflammation
Sesame seeds may fight inflammation.
Long-term, low-level inflammation may play a role in many chronic conditions, including obesity and cancer, as well as heart and kidney disease.
When people with kidney disease ate a mixture of 18 grams of flax seeds and 6 grams each of sesame and pumpkin seeds daily for 3 months, their inflammatory markers dropped 51‒79%.

However, because this study tested a mixture of seeds, the anti-inflammatory impact of sesame seeds alone is uncertain.
Still, animal studies of sesame seed oil also suggest anti-inflammatory effects.
This may be due to sesamin, a compound found in sesame seeds and their oil.
Summary: Preliminary research suggests that sesame seeds and their oil may have anti-inflammatory properties.
7. Sesame seeds are great sources of B vitamins
Sesame seeds are a good source of certain B vitamins, which are distributed both in the hull and seed.
Removing the hull may either concentrate or remove some of the B vitamins.
Three tablespoons (30 grams) of unhulled sesame seeds provide:
- Thiamine (B1): 17% of your daily need
- Niacin (B3): 11% of your daily need
- Vitamin B6: 5% of your daily need
B vitamins are essential for many bodily processes, including proper cell function and metabolism.
Summary: Sesame seeds are a good source of thiamine, niacin, and vitamin B6, which are necessary for proper cellular function and metabolism.
8. Sesame seeds may aid in blood cell formation
To make red blood cells, your body needs several nutrients — including ones found in sesame seeds.
Three tablespoons (30 grams) of sesame seeds give:
- Iron: 24% of the recommended daily intake. Iron is an essential component of hemoglobin, which carries oxygen in your red blood cells.
- Copper: 136% of the recommended daily intake. Copper helps make hemoglobin.
- Vitamin B6: 5% of the recommended daily intake. Vitamin B6 also helps make hemoglobin.
Soaked, roasted, or sprouted sesame seeds may increase the absorption of these minerals.
Summary: Sesame seeds supply iron, copper, and vitamin B6, which are needed for blood cell formation and function.
9. Sesame seeds may aid blood sugar control
Sesame seeds are low in carbs while high in protein and healthy fats — all of which may support blood sugar control.
Additionally, these seeds contain pinoresinol, a compound that may help regulate blood sugar by inhibiting the action of the digestive enzyme maltase.
Maltase breaks down the sugar maltose, which is used as a sweetener for some food products. It’s also produced in your gut from the digestion of starchy foods like bread and pasta.

If pinoresinol inhibits your digestion of maltose, this may result in lower blood sugar levels. However, human studies are needed.
Summary: Sesame seeds may aid blood sugar control because they’re low in carbs and high in quality protein and healthy fats. What’s more, they contain a plant compound that may help in this regard.
10. Sesame seeds are rich in antioxidants
Animal and human studies suggest that consuming sesame seeds may increase the overall amount of antioxidant activity in your blood.
The lignans in sesame seeds function as antioxidants, which help fight oxidative stress — a chemical reaction that may damage your cells and increase your risk of many chronic diseases.
Additionally, sesame seeds contain a form of vitamin E called gamma-tocopherol, an antioxidant that may be especially protective against heart disease.
Summary: Plant compounds and vitamin E in sesame seeds function as antioxidants, which combat oxidative stress in your body.
11. Sesame seeds may support your immune system
Sesame seeds are a good source of several nutrients crucial for your immune system, including zinc, selenium, copper, iron, vitamin B6, and vitamin E.
For example, your body needs zinc to develop and activate certain white blood cells that recognize and attack invading microbes.
Keep in mind that even mild to moderate zinc deficiency can impair immune system activity.
Sesame seeds supply about 20% of the recommended daily intake for zinc in a 3-tablespoon (30-gram) serving.
Summary: Sesame seeds are a good source of several nutrients that are important for immune system function, including zinc, selenium, copper, iron, vitamin B6, and vitamin E.
12. Sesame seeds may soothe arthritic knee pain
Osteoarthritis is the most common cause of joint pain and frequently affects the knees.
Several factors may play a role in arthritis, including inflammation and oxidative damage to the cartilage that cushions joints.
Sesamin, a compound in sesame seeds, has anti-inflammatory and antioxidant effects that may protect your cartilage.
In a 2-month study, people with knee arthritis ate 5 tablespoons (40 grams) of sesame seed powder daily alongside drug therapy. They experienced a 63% decrease in knee pain compared to only a 22% decrease for the group on drug therapy alone.
Additionally, the sesame seed group showed greater improvement in a simple mobility test and larger reductions in certain inflammatory markers compared to the control group.
Summary: Sesamin, a compound in sesame seeds, may help reduce joint pain and support mobility in arthritis of the knee.
13. Sesame seeds may support thyroid health
Sesame seeds are a good source of selenium, supplying 18% of the RDI in both unhulled and hulled seeds.
Your thyroid gland contains the highest concentration of selenium of any organ in your body. This mineral plays a vital role in making thyroid hormones.
In addition, sesame seeds are a good source of iron, copper, zinc, and vitamin B6, which also support the production of thyroid hormones and aid thyroid health.
Summary: Sesame seeds are good sources of nutrients — such as selenium, iron, copper, zinc, and vitamin B6 — that support thyroid health.
14. Sesame seeds may aid hormone balance during menopause
Sesame seeds contain phytoestrogens, plant compounds that are similar to the hormone estrogen.
Therefore, sesame seeds might be beneficial for women when estrogen levels drop during menopause. For example, phytoestrogens may help counteract hot flashes and other symptoms of low estrogen.
What’s more, these compounds may decrease your risk of certain diseases — such as breast cancer — during menopause. However, further research is needed.
Summary: Phytoestrogens are compounds found in sesame seeds that may benefit women who are undergoing menopause.
15. Sesame seeds are easy to add to your diet
Sesame seeds can give a nutty flavor and subtle crunch to many dishes.
To enhance the flavor and nutrient availability of sesame seeds, roast them at 350℉ (180℃) for a few minutes, stirring periodically, until they reach a light, golden brown.
Try adding sesame seeds to:
- steamed broccoli
- hot or cold cereal
- granola and granola bars
- bread and muffins
- salad dressing
Additionally, you can use sesame seed butter — also known as tahini — in place of peanut butter or hummus.
