Ajonjoli (Sesame Seeds): Nutrition, Benefits, Uses and Side Effects
The tiny, flat sesame seeds that top breads, bagels, and sweets worldwide are called ajonjoli in Spanish. They're small but nutritious. Here’s what’s inside them, how they may help your health, how to use them, and who should be careful.
What Is Ajonjoli?
Ajonjoli comes from the sesame plant (Sesamum indicum), one of the oldest oil crops people have grown. The seeds come in white, black, brown and golden varieties. White seeds taste mild and nutty, while black seeds have a stronger, slightly bitter flavor. Toasting any of them brings out a richer aroma.
Nutrition at a Glance
One tablespoon (about 9 grams) of dried sesame seeds gives you roughly:
- Calories: about 50
- Protein: around 1.5 grams
- Healthy fats: about 4.5 grams
- Fiber: about 1 gram
- Minerals: calcium, iron, magnesium, zinc, copper and manganese
These values vary a little by variety and by whether the seeds are hulled. Unhulled seeds keep more fiber and calcium. Sesame also contains plant compounds called lignans, including sesamin, which are being studied for their antioxidant effects.
Possible Health Benefits
1. Supports heart health. Sesame is rich in unsaturated fats. Some small studies suggest that eating it regularly may help lower LDL (“bad”) cholesterol and triglycerides. Lignans may also play a role.
2. May help with blood pressure. A few small trials have linked sesame consumption or sesame oil with modest drops in blood pressure. The evidence is still limited, so treat sesame as a helpful food, not a treatment.
3. Good for bones. Calcium, magnesium and zinc all matter for strong bones. Sesame adds a little to your daily intake of each, which is useful if you eat little dairy.
4. Provides antioxidants. Sesamin and related compounds may help the body handle oxidative stress, which is linked to long-term inflammation.
5. Adds plant protein and fiber. A sprinkle won’t replace a meal, but it gives vegetarian and vegan diets a small boost in protein, and the fiber supports digestion.
6. May support blood sugar balance. Fiber, healthy fats and protein slow down how quickly meals raise blood sugar. Early research looks promising, but more human studies are needed.
Easy Ways to Use Ajonjoli
You don’t need a special recipe. Try these:
- Sprinkle it over salads, rice, soups, noodles or roasted vegetables.
- Toast and crush it into a seasoning blend. A mix of toasted sesame and salt is a classic.
- Make tahini. Ground sesame paste is the base of hummus and many dressings.
- Bake with it in breads, crackers, rolls and cookies.
- Make sweets. Sesame brittle and sesame balls are popular in many cuisines, though they add sugar.
- Use the oil. Toasted sesame oil is great for finishing dishes, while light sesame oil works for gentle cooking.
Tip: Whole seeds can pass through your body undigested. Grinding or chewing them well helps you absorb more nutrients.
Possible Side Effects and Precautions
Sesame is safe for most people in normal food amounts, but keep these points in mind:
- Allergy: Sesame is a recognized major food allergen. Reactions can range from hives and stomach upset to serious breathing problems. If you suspect an allergy, avoid sesame and see a doctor.
- Digestive discomfort: Eating a lot at once, especially for people not used to the fiber, may cause bloating or gas.
- Calories add up: Sesame is energy-dense. Tahini and sesame sweets can quickly increase calorie intake.
- Medication interactions: Because sesame may slightly lower blood sugar and blood pressure, people taking medicine for diabetes or hypertension should keep their intake steady and consult their doctor before using large or supplement-level amounts.
- Oxalates: Sesame contains oxalates, which people prone to kidney stones may need to limit. Ask your doctor if this applies to you.
- Pregnancy: Normal food amounts are generally fine. Avoid concentrated supplements unless a doctor approves.
How to Store Ajonjoli
Because of their natural oils, sesame seeds can go rancid. Keep them in an airtight container in a cool, dark place, or in the fridge or freezer for longer storage. If they smell bitter or sour, throw them out.
