**How do different types of fats affect heart health?**
Different fats impact heart health in various ways. Saturated fats, found in foods like red meat and full-fat dairy, can elevate levels of bad cholesterol (LDL), increasing heart disease risk. On the other hand, unsaturated fats, such as those found in olive oil, avocados, and fatty fish, are considered heart-healthy and can improve cholesterol levels by boosting good cholesterol (HDL). Additionally, trans fats found in many processed foods are highly detrimental and should be avoided entirely due to their negative effects on cardiovascular health.
