This common cooking oil linked to raising heart disease risk; know its side effects |

Coconut oil has become a household name, often marketed as a “superfood” and a natural alternative to processed fats. From coffee blends to stir-fries, health enthusiasts have embraced it for perceived benefits such as weight management, immune support, and improved heart health.However, emerging research and expert advice indicate that coconut oil may not be as heart-friendly as its reputation suggests. Despite being plant-based, it is unusually high in saturated fat, a nutrient long associated with higher cholesterol levels and increased cardiovascular disease risk. Understanding these risks is essential before making coconut oil a staple in your diet.

Coconut oil may increase heart disease risk

According to a study published in Nutrients, coconut oil may raise LDL (“bad”) cholesterol and total cholesterol levels, which can increase the risk of heart disease. While it may slightly raise HDL (“good”) cholesterol, the overall effect still poses concerns for cardiovascular health. Excessive consumption can contribute to plaque build-up in arteries, elevated blood pressure, and a higher risk of heart attacks or strokes. Coconut oil’s high saturated fat content may also promote inflammation, affect blood vessel function, and lead to insulin resistance over time, potentially impacting metabolic health. Over time, the regular use of coconut oil in cooking or baking can increase the risk of atherosclerosis, a condition where arteries become clogged with plaque. This can reduce blood flow, strain the heart, and significantly raise the likelihood of heart attacks and other cardiovascular events.

Raises LDL (“Bad”) cholesterolClinical trials, including a randomised study published in BMJ Open, found that coconut oil significantly raises LDL cholesterol compared to unsaturated oils like olive oil. High LDL is a major risk factor for atherosclerosis, coronary artery disease, and other cardiovascular complications.Raises HDL (“Good”) cholesterolCoconut oil may also increase HDL cholesterol, often cited by supporters as a benefit. However, cardiologists emphasise that higher HDL does not offset the negative effects of elevated LDL. The net impact on cardiovascular health remains potentially harmful (Harvard T.H. Chan School of Public Health).

Potential side effects of coconut oil

While occasional use of coconut oil may be safe, excessive consumption can have negative effects on heart health, including:

These effects are especially concerning for individuals with existing heart disease, high cholesterol, or other cardiovascular risk factors.
