Is Palm Oil Healthy? What Science Says
Palm oil is one of the most common edible oils globally, found in processed snacks, baked goods, and fried foods. But is it truly healthy? With rising concerns over saturated fats, this article breaks down the facts backed by recent research (2024–2025).

What Is Palm Oil and Why Is It Everywhere?
Palm oil is extracted from the fruit of oil palm trees, native to Southeast Asia. Due to its high yield, stability at high temperatures, and low cost, it dominates the global vegetable oil market. It appears in margarine, chocolates, instant noodles, and even cosmetics—making understanding its health impact crucial for everyday choices.
The Fat Profile: Saturated, Unsaturated, and Beyond
Palm oil contains about 50% saturated fat, 40% unsaturated fat (including heart-friendly monounsaturated fats), and small amounts of polyunsaturated fats. Unlike palm kernel oil, which is richer in saturated fats, crude palm oil has a balanced fatty acid composition. Recent studies confirm that moderate intake of palm oil doesn’t inherently increase LDL cholesterol more than other oils when consumed in moderation.
Health Impacts: What Recent Studies Reveal
Long-term consumption of high saturated fat diets raises cardiovascular risks, but emerging 2024 research shows palm oil’s effects depend on overall dietary patterns. A meta-analysis in the Journal of Nutrition & Metabolism (2024) found that replacing saturated fats with palm oil omega-6-rich fractions had neutral or slightly positive effects on lipid profiles when balanced with fiber and unsaturated fats. However, excessive intake without dietary diversity may promote inflammation.
- Palm oil contains palmitic acid, a saturated fat linked to elevated LDL in large amounts.
- It also provides tocotrienols, natural antioxidants with potential anti-inflammatory properties.
- Unlike trans fats, palm oil does not artificially raise bad cholesterol—making it a better choice than partially hydrogenated oils.
