In a 2022 randomized crossover trial in healthy adults, replacing olive oil with ghee increased apo B and non-HDL cholesterol, with LDL-cholesterol not clearly differing, while many cardiometabolic markers (like weight and blood pressure) stayed unchanged over the study periods.
What the randomized trial tested
The study compared dietary ghee versus olive oil in healthy adults using a two-period, crossover randomized design, focusing on cardiometabolic risk factors.
Because it was crossover, participants acted as their own control across two diet periods, which helps reduce between-person differences in baseline cholesterol.
Study design and timeline
The trial is reported as "a two-period, crossover, randomised trial" in the journal British Journal of Nutrition, with publication timing shown as late 2022 on the journal listing.
Participants completed both interventions and the investigators reported that energy and macronutrient intakes were similar, but fat composition differed between the ghee and olive oil periods.
- Design: randomized, two-period crossover
- Population: healthy adults
- Intervention contrast: ghee vs olive oil
- Primary focus: cardiometabolic risk factors including lipid-related measures
Key results on cholesterol-related risk
Relative to olive oil, the ghee diet increased apo B and non-HDL cholesterol, indicating a less favorable lipoprotein risk profile for that specific substitution.
The study also reports that LDL-cholesterol was not significantly different between diets in their results summary, even though other lipid fractions shifted.
| Outcome (lipid-related) | Direction with ghee vs olive oil | What it implies |
|---|---|---|
| Apo B | Increased | More atherogenic particle burden signal (risk-related surrogate) |
| Non-HDL cholesterol | Increased | Higher "remnant/atherogenic" cholesterol load relative to protective HDL |
| LDL-cholesterol | No significant difference reported | LDL alone didn't capture the full substitution effect |
| TAG (fasting, postprandial) | No significant differences reported (in results summary) | Triglyceride response was not the main differentiator between diets |
Why these outcomes matter
In practical terms, apo B is often used as a summary marker of the number of atherogenic lipoprotein particles, so increases can be interpreted as a "particle-count" unfavorable shift.
Non-HDL cholesterol is broadly atherogenic cholesterol excluding HDL, so an increase supports the interpretation that ghee led to a higher-risk cholesterol pattern than olive oil in this trial context.
Compliance, diet composition, and fat quality
The investigators quantified diet composition and used dietary recalls across weeks, and participants also rated compliance with consuming the assigned oil/fat.
The crucial nuance is that this wasn't just "same calories, different label"; the intervention altered the fat composition, with the paper's abstract details indicating different fatty acid patterns (e.g., saturated and cholesterol contributions shifting with ghee vs olive oil).
What stayed the same (and what didn't)
In the results summary, there were no significant differences between ghee and olive oil for measures like body weight, waist circumference, and blood pressure, suggesting limited effects on anthropometrics during the study periods.
Similarly, fasting glucose, insulin resistance, and PAI-1 were reported as not significantly different between diets in the summary, indicating that the lipid-direction findings weren't mirrored by broad metabolic changes.
- Cholesterol-related risk markers moved (apo B and non-HDL increased)
- LDL-cholesterol was not significantly different in the summary
- Many cardiometabolic endpoints (weight, BP, glucose/insulin resistance markers) showed no significant diet-by-diet differences
How to translate this into everyday decisions
If your goal is to improve "cholesterol profile," this trial supports choosing olive oil rather than using ghee as the direct replacement fat in healthy adults-at least under the study conditions and time horizon.
Importantly, this doesn't mean ghee is universally "bad" for everyone; it means the head-to-head substitution performed worse on specific lipid-related risk markers than olive oil in this randomized crossover trial.
Related context: what makes this "randomized trial" newsworthy
Diet substitution studies often fail to isolate causality because real diets contain many interacting components, but randomized crossover designs aim to better isolate the effect of changing the cooking/consumed fat.
The trial's sample-size rationale referenced an expected LDL difference scale in prior diet work, reflecting that investigators treated LDL-change as a key signal while still measuring broader lipid and risk-factor outcomes.
Media-ready takeaway: In healthy adults, swapping olive oil for ghee raised apo B and non-HDL cholesterol-so the substitution moved atherogenic lipid surrogates in a less favorable direction.
FAQ
One practical "olive oil vs ghee" rule
If you're choosing a cooking fat with cholesterol-related risk reduction in mind, treat olive oil as the default replacement for ghee based on this randomized crossover evidence in healthy adults.
If you tell me your dietary pattern (e.g., typical breakfast fats, how often you use ghee, and whether you track lipids), I can help you apply the trial's directionality to your routine.
Helpful tips and tricks for Ghee Randomized Trial Healthy Adults Vs Olive Oil Shocks
Was this trial actually randomized?
Yes-the study is described as a randomized trial with a two-period crossover design comparing diets rich in ghee versus olive oil.
Did ghee lower LDL-cholesterol compared with olive oil?
No-LDL-cholesterol was reported as not significantly different between ghee and olive oil in the trial's results summary, even though other lipid-related markers changed.
What changed most clearly?
Ghee increased apo B and non-HDL cholesterol relative to olive oil, both of which are commonly used cholesterol-related risk surrogates.
Did ghee affect weight, blood pressure, or glucose control?
In the results summary, there were no significant differences for body weight, waist circumference, blood pressure, fasting glucose, insulin resistance, or PAI-1 between the two diets.
Is this study from 2022?
The journal listing shows the study in late 2022 (Volume 128, Issue 9) under the title "Effects of diets rich in ghee or olive oil on cardiometabolic risk factors in healthy adults: a two-period, crossover, randomised trial."
Does this mean olive oil is always better?
For this specific substitution in this specific healthy-adult trial, olive oil performed better on apo B and non-HDL cholesterol than ghee.
