Despite having a single ingredient, tahini is nutritionally dense. A hundred grams carries 590 calories, and behind those calories sits a notable mineral profile.
How do the macronutrients break down?
A hundred grams of tahini holds around 55 grams of fat, 17 grams of protein and 21 grams of carbohydrate.
A significant share of that carbohydrate is fibre, roughly 9 grams. Digestible carbohydrate is therefore low.
The protein level is high for a plant source. For comparison: peanut butter carries around 25 grams, almond butter 21.
Fat accounts for about eighty percent of total calories. That is the component making tahini a dense product.
A tablespoon is around 15 grams and carries 90 calories. Portion calculations should use that unit.
Is the calcium content genuinely high?
High, with one condition: whether the sesame was dehulled is decisive.
Tahini made from dehulled sesame contains around 420 milligrams of calcium per hundred grams.
In whole-seed sesame paste that figure reaches 900. At first glance the unhulled product looks far superior.
But the hull also contains oxalate. Oxalate binds calcium and lowers its absorption markedly.
The result is that calcium from dehulled tahini is absorbed at a higher rate. Even with a lower total, more calcium may reach the body.
For comparison: a hundred millilitres of milk contains around 120 milligrams of calcium with high absorption. Two tablespoons of tahini provide around 125 milligrams.
Where does it stand on iron?
Tahini contains around 4 milligrams of iron per hundred grams, a good figure among plant sources.
That iron is non-heme, however, and its absorption rate is low.
The most practical way to improve absorption is taking it with a vitamin C source. Using lemon alongside a tahini sauce is a functional habit in that respect.
Factors that lower absorption exist too: high calcium in the same meal, tannins in tea and coffee, and phytate.
Because tahini contains both calcium and iron it carries a competition within itself. That does not make it worthless; it only shows it should not be counted as an iron source on its own.

| Protein | 17 g | 25 g | 21 g |
| Fat | 55 g | 50 g | 56 g |

How is the fat profile distributed?
Sesame oil is rich in unsaturated fat.
Roughly forty percent is monounsaturated and forty percent polyunsaturated. Saturated fat sits around fourteen percent.
Most of the polyunsaturated fraction is linoleic acid, that is, omega-6. Sesame oil is not rich in omega-3.
To balance that, including omega-3 sources such as walnuts, flaxseed and fish in the diet makes sense.
The quality of the fat also depends on processing. Excessive roasting and milling at high temperature oxidise part of the fatty acids.
What do sesamin and sesamol do?
Sesame contains two compounds in the lignan group: sesamin and sesamolin.
These compounds have antioxidant properties and increase the resistance of sesame oil to oxidation.
They are the reason sesame oil turns rancid later than other vegetable oils.
Their effects on health are under research, but it is too early to draw firm conclusions from that. Tahini is a valuable product for its general nutritional profile, not because of these compounds.
Roasting converts part of them to sesamol, a stronger antioxidant. That explains why roasted tahini is slightly more resistant to oxidation.
What about protein quality?
Tahini is a good source of methionine among plant proteins.
Methionine is an amino acid found in limited amounts in pulse proteins. Eating tahini together with pulses therefore completes the amino acid profile.
Hummus is the classic example of that pairing: chickpeas rich in lysine, tahini rich in methionine.
Tahini on its own is limited in lysine. That does not make it inadequate; the issue disappears when different sources come together across a day.
The protein quantity should not be overlooked either: two tablespoons provide around 5 grams.
How much should be eaten daily?
A general suggestion is one to two tablespoons a day, that is 15 to 30 grams.
That amounts to 90 to 180 calories and covers six to twelve percent of calcium needs.
More is not harmful, but the calorie density deserves attention. For anyone managing weight, portion control is decisive.
In sports nutrition the amount can rise. For an athlete with high energy needs, tahini is a practical way to get dense calories in a small volume.
With children, consistency calls for care. Under one year of age tahini should be thinned and given under supervision.
Who should be careful?
A sesame allergy rules this product out entirely. Sesame is among the allergens that must be declared on labels, and tahini is sesame in its most concentrated form; no tolerance for traces should be assumed.
For people with a history of kidney stones, oxalate may come into the discussion; there, dehulled tahini is preferred over whole-seed sesame paste.
For anyone controlling weight, measuring the portion matters. Spooning straight from the jar leads to quantities rising unnoticed.
For those with digestive sensitivity the high fat content can cause discomfort; reducing the amount and spreading it through the meal helps.
How is nutritional value preserved in the kitchen?
Not cooking tahini at high temperature is the most practical rule. Fatty acids and antioxidant compounds are affected by heat.
When making a sauce, adding tahini to a mixture taken off the heat is better than boiling it.
Keep the jar away from light. Light is one of the factors accelerating oxidation of the oil.
Use a clean spoon and wipe the rim; those simple habits delay rancidity.
Tahini served with fresh fruit or lemon juice is more efficient in terms of iron absorption. Putting an orange alongside it at breakfast is a good pairing made without thinking about it.
