Various types of dietary fats include saturated, unsaturated, and trans fats, each with different impacts on health. Unsaturated fats, mainly found in olive oil and fish, are beneficial for heart health when consumed in moderation. Conversely, saturated fats, found in red meat and full-fat dairy, can elevate cholesterol levels when overconsumed. Trans fats, often present in processed foods, are harmful and should be avoided. Understanding these types can help individuals make informed dietary choices for better overall health.
