Ghee and Cholesterol: What a Recent Clinical Trial Shows
A recent clinical trial directly compared a ghee-rich diet to an olive-oil-rich diet. Here is what it measured on cholesterol, without loose generalizations.
A randomized crossover clinical trial directly compared a diet rich in ghee to a diet rich in olive oil over four weeks: the ghee-rich diet raised apo-B and non-HDL cholesterol compared with the olive-oil-rich diet, with no significant difference in LDL cholesterol or triglycerides between the two groups. This result adds nuance, without contradicting it, to what our article ghee, dangers and precautions already notes about caution with elevated cholesterol.
Why compare ghee to olive oil rather than butter?
Ghee is 60-65% saturated fat, which naturally invites comparison against a reference fat for cardiovascular health, olive oil, rich in monounsaturated fat. This methodological choice allows a more realistic measure of the differential effect, within an otherwise balanced diet, rather than an isolated effect of ghee consumed in excess.
What the crossover clinical trial found
A study by Mohammadi Hosseinabadi and Nasrollahzadeh, published in 2021 in the British Journal of Nutrition (vol. 128, no. 9) (see the study on Google Scholar), followed healthy adults in a two-period crossover protocol of four weeks each, with each participant consuming, in turn, a ghee-enriched diet and an olive-oil-enriched diet. Result: the ghee-rich diet led to a rise in apo-B and non-HDL cholesterol compared with the olive-oil-rich diet, two markers associated with cardiovascular risk. On the other hand, no significant difference was observed in LDL cholesterol, triglycerides, fasting and post-meal blood glucose, or insulin.
How to interpret this result honestly
| Marker measured | Ghee-rich diet vs. olive-oil-rich diet |
|---|---|
| Apo-B | Significant increase |
| Non-HDL cholesterol | Significant increase |
| LDL cholesterol | No significant difference |
| Triglycerides | No significant difference |
| Fasting and post-meal glucose | No significant difference |
Apo-B and non-HDL cholesterol are considered by some cardiovascular research as markers at least as informative as LDL alone, since they capture the full range of potentially atherogenic particles. This trial's result therefore deserves to be taken seriously, without over-interpreting it as definitive proof of harm: it is a single study, over four weeks, in healthy adults, whose results may not extend identically to every profile, particularly people who already have elevated cholesterol or an established cardiovascular condition.
What this result does not say
- It does not show that ghee is dangerous in a normal, moderate diet for a healthy person;
- It does not establish a fixed maximum quantity to stay under;
- It does not replace individualized medical advice, especially for anyone with elevated cholesterol or cardiovascular risk factors;
- It concerns a comparison against olive oil specifically, not against every other cooking fat.
Practical takeaways
For a healthy person without elevated cholesterol, this result mainly supports what is already common nutritional advice: alternating fat sources, including plenty of monounsaturated fats like olive oil, rather than relying on a single fat for all cooking and seasoning needs. Ghee retains its place in Ayurvedic cooking and its documented uses, detailed in homemade ghee, but this trial supports moderation rather than unrestricted daily use, particularly for anyone already monitoring their cholesterol.
Precautions
This result reinforces rather than replaces the precautions already detailed in ghee, dangers and precautions: moderate consumption is especially advised for anyone with cardiovascular risk factors or existing high cholesterol, under regular medical monitoring.

Your questions about ghee and cholesterol
Does ghee raise cholesterol more than olive oil?
A 2021 randomized crossover trial found a ghee-rich diet raised apo-B and non-HDL cholesterol compared with an olive-oil-rich diet over four weeks, with no significant difference in LDL cholesterol or triglycerides.
Should I stop using ghee because of this study?
Not necessarily for a healthy person eating it in moderation. The result supports moderation and varying fat sources rather than a strict ban, especially important for anyone already monitoring elevated cholesterol.
What are apo-B and non-HDL cholesterol?
Two blood markers that some cardiovascular research considers at least as informative as LDL cholesterol alone, since they reflect a broader range of potentially atherogenic particles.
Does this study prove ghee causes heart disease?
No. It is a single four-week trial in healthy adults measuring blood markers, not cardiovascular events. It shows a measurable effect on certain markers, not a proven causal link to disease.
