Is coconut oil healthy or unhealthy?

Coconut oil is controversial. It's 82% saturated fat (more than butter), which can raise cholesterol. However, it contains MCTs that may boost metabolism. Use in moderation—it's not a health food, but occasional use is fine.

Is coconut oil better than other oils for cooking?

Coconut oil has a high smoke point (350°F refined, 280°F virgin), making it suitable for medium-heat cooking. For high-heat cooking, avocado oil is better. For health benefits, olive oil is superior.
