A compound found in pomegranate peel reduced cholesterol by up to 76% and belly fat by 42% in laboratory and mouse studies, according to Gram Research analysis of 2026 research published in the Journal of Agricultural and Food Chemistry. The substance also increased beneficial gut bacteria and improved liver health. However, these results are from early-stage research using cells and animals, not humans, so it’s too soon to recommend pomegranate peel as a treatment for high cholesterol or weight gain.
Scientists discovered a special compound in pomegranate peel that appears to fight high cholesterol and weight gain. In lab tests and mouse studies, this natural substance reduced cholesterol by up to 76% and belly fat by 42%. It also helped improve the balance of good bacteria in the digestive system. While these results are promising, the research is still in early stages, and more human studies are needed before we know if eating pomegranate peel could have the same benefits for people.
Key Statistics
A 2026 research article found that a compound isolated from pomegranate peel reduced total cholesterol by 76.2% and triglycerides by 70.4% in human liver cells treated with unhealthy fats.
In mice fed a high-fat diet, the pomegranate peel compound reduced belly fat by 42.1% and epididymal fat by 41.5% without reducing food intake, suggesting it changed how the body processes fat rather than reducing appetite.
The pomegranate peel compound increased good cholesterol (HDL) by 36.4% and reduced triglycerides by 37% in high-fat diet mice, while also improving liver health markers by 27.9% to 32.1%.
Research showed the pomegranate peel compound enriched beneficial gut bacteria including Lactobacillus and Bifidobacterium while reducing the ratio of harmful Firmicutes bacteria, suggesting prebiotic activity alongside cholesterol-lowering effects.
The Quick Take
- What they studied: Whether a natural fiber-like compound found in pomegranate peel could lower cholesterol levels and reduce weight gain
- Who participated: The research used lab-grown human liver cells and mice fed a high-fat diet. No human participants were involved in this study.
- Key finding: The pomegranate peel compound reduced total cholesterol by up to 76% and triglycerides (a type of blood fat) by 70% in lab cells, and reduced belly fat by 42% in mice
- What it means for you: This research suggests pomegranate peel might help with cholesterol and weight management, but it’s too early to recommend it as a treatment. More studies in humans are needed before we know if these benefits apply to people eating pomegranate peel.
The Research Details
Researchers isolated a special compound called PPP-1 from pomegranate peel and tested it in two ways. First, they added it to human liver cells that had been treated with unhealthy fats to see if it could improve cholesterol levels. Second, they fed the compound to mice that were eating a high-fat diet (similar to a junk food diet) and tracked changes in their weight, fat storage, and blood cholesterol over time.
The scientists also examined how the compound affected the bacteria living in the mice’s digestive systems, since these bacteria play an important role in overall health. They used advanced lab techniques to identify which bacteria increased or decreased after eating the pomegranate peel compound.
This type of research is called “preclinical” because it happens in labs and animals before any human testing. It’s an important first step to understand whether a natural substance might be helpful, but it doesn’t prove the same effects would happen in people.
Testing in both lab cells and living animals gives scientists confidence that a compound works through real biological mechanisms, not just by chance. This two-step approach helps researchers understand not just whether something works, but how it works in a living body.
The study was published in a respected scientific journal focused on food and agriculture research. The researchers used detailed chemical analysis to identify exactly what the pomegranate peel compound was made of and how it was structured. However, because this is early-stage research using only cells and animals (not humans), the results should be viewed as promising but not yet proven for people. The study did not include a comparison group of mice that didn’t receive the compound, which would have strengthened the findings.
What the Results Show
In human liver cells treated with unhealthy fats, the pomegranate peel compound reduced total cholesterol by 76.2% and triglycerides by 70.4%. It also increased “good” cholesterol (HDL) while decreasing “bad” cholesterol (LDL). The compound appeared to work by activating specific proteins in cells that control how much cholesterol and fat the body makes.
In mice eating a high-fat diet, the pomegranate peel compound prevented excessive weight gain and reduced belly fat by 42.1% and 41.5%, respectively. Importantly, the mice didn’t eat less food—they gained less weight despite eating the same amount, suggesting the compound changed how their bodies processed fat rather than reducing appetite.
The compound also improved liver health in the mice. It lowered liver enzymes that indicate damage, suggesting it protected the liver from the harmful effects of a high-fat diet. Blood tests showed the mice had 36.4% more good cholesterol and 37% less triglycerides after receiving the compound.
The pomegranate peel compound also changed the bacteria in the mice’s digestive systems in beneficial ways, increasing helpful bacteria like Lactobacillus and Bifidobacterium while reducing harmful bacteria. These bacteria changes are important because they’re linked to better metabolism and weight management.
The research showed that the pomegranate peel compound worked through a specific biological pathway involving proteins called SIRT1 and AMPK. These proteins act like metabolic switches that tell cells to burn fat more efficiently. The compound also reduced the activity of genes that tell cells to make more cholesterol and fat. Advanced analysis of metabolites (the chemical byproducts of metabolism) confirmed that the compound normalized many obesity-related chemical imbalances in the mice’s bodies.
Pomegranate has been studied before for its health benefits, but this research identifies a specific compound in pomegranate peel with dual benefits: it acts like a prebiotic (feeding good bacteria) while also directly lowering cholesterol and fat. Previous research on pomegranate focused mainly on antioxidants in the juice, not the peel. This study suggests the peel—often discarded—may be more valuable than previously thought.
This research only tested the isolated compound in lab cells and mice, not in humans. The effects in people might be different or smaller. The study didn’t compare the pomegranate peel compound to other known cholesterol-lowering treatments or natural compounds. We don’t know what dose would be needed for humans or whether eating whole pomegranate peel would have the same benefits as the isolated compound. The mice in this study were all male, so we don’t know if the results would be the same in females.
The Bottom Line
This research is too early to recommend pomegranate peel as a cholesterol or weight-loss treatment. The findings are promising enough to justify human studies, but until those are completed, pomegranate peel should not replace proven cholesterol medications or weight management strategies. If you’re interested in pomegranate for health reasons, eating the whole fruit (including some peel) as part of a balanced diet is safe and may have other health benefits, but don’t expect dramatic cholesterol or weight changes based on this research alone.
People with high cholesterol, obesity, or fatty liver disease should be most interested in this research, but they should not change their treatment based on these early findings. Healthcare providers studying natural compounds for metabolic health should follow this research closely. Anyone considering pomegranate supplements should wait for human studies before spending money on them.
If human studies are conducted, it would typically take 3-5 years to determine whether pomegranate peel compounds have real benefits for people. Any benefits seen in humans would likely take weeks to months to appear, not days.
Frequently Asked Questions
Can eating pomegranate peel help lower my cholesterol?
Research shows a compound in pomegranate peel reduced cholesterol by 76% in lab cells and improved cholesterol in mice, but human studies haven’t been done yet. Eating pomegranate as part of a healthy diet is safe, but don’t expect it to replace cholesterol medications without talking to your doctor.
Is pomegranate peel safe to eat?
Pomegranate peel is generally safe to eat in small amounts, though it’s bitter and tough. Most people eat the seeds and juice instead. This research isolated a specific compound from the peel, which is different from eating whole peel. Check with your doctor if you take medications, as pomegranate can interact with some drugs.
How much pomegranate would I need to eat to get these benefits?
We don’t know yet. This research tested an isolated compound in controlled doses—not whole pomegranate fruit. Human studies would be needed to determine effective doses. Don’t assume eating more pomegranate will give you the same results as the lab research.
When will pomegranate peel be available as a treatment?
This is early-stage research. If human studies are approved and funded, it would take 3-5 years minimum to determine safety and effectiveness in people. Pomegranate peel supplements based on this research are not yet recommended by health organizations.
Does this research apply to pomegranate juice or just the peel?
This study focused specifically on a compound in the peel, not the juice. Pomegranate juice has different compounds and has been studied separately. The peel is usually discarded, so this research suggests it might have untapped health potential, but more work is needed.
