Is Groundnut Oil Healthy for Your Heart? A Cardiologist Explains
Groundnut oil — also called peanut oil or singtel — is one of the most common cooking oils in Gujarati homes. But many people wonder: is it actually good for the heart?
Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, recently shared a clear and helpful answer.
The Good News: Yes, It Can Be Heart-Friendly
Groundnut oil is rich in monounsaturated fats — the kind of fat that is considered friendly for the heart. It also contains Vitamin E, a natural antioxidant. Together, these nutrients can help:
- Lower bad cholesterol (LDL) levels
- Support overall heart health
- Protect cells from damage
So when used correctly, groundnut oil is a reasonable choice for everyday cooking.
But There Is a Catch
Not all groundnut oil is the same, and how you use it matters a lot.
Refined oil or repeatedly heated oil can lose its nutrients over time. Reusing cooking oil — which many households do — can actually increase health risks rather than reduce them.
Groundnut oil is also relatively high in omega-6 fatty acids. Omega-6 is not harmful on its own, but if it is not balanced with enough omega-3 fatty acids (found in foods like flaxseeds, walnuts, and fish), it can quietly promote inflammation in the body. Chronic inflammation is linked to heart disease.
Simple Tips for Using Groundnut Oil Wisely
Dr. Pachani recommends three straightforward steps:
- Choose cold-pressed groundnut oil over heavily refined versions. Cold-pressed oil retains more natural nutrients.
- Use it in moderation. Even healthy oils add calories, so portion control matters.
- Rotate it with other healthy oils — such as mustard oil or olive oil — so your body gets a wider range of beneficial fats.
The Bottom Line
Groundnut oil is not harmful — in fact, it has real benefits for heart health. The key is choosing the right type, not overheating it, and not relying on just one oil all the time. Small, steady changes in your kitchen can make a meaningful difference to your heart over the years.
