Palm oil, palm kernel oil, and coconut oil — the so-called tropical oils — got a bad reputation because they’re high in saturated fat, which has long been linked to heart disease. Saturated fat boosts “bad” LDL cholesterol and triglycerides, both of which are risk factors for heart disease. Palm oil, which is 50% saturated, has a more favorable fatty acid composition than palm kernel oil and coconut oil, which are more than 85% saturated. In general, the higher the saturated fat content, the more solid a fat is at room temperature. Palm oil is semisolid at room temperature but can be processed into liquid cooking oil.
