Which type of fat is found predominantly in plant-based sources and is considered healthier for heart health?

• A. Saturated fats
• B. Trans fats
• C. Unsaturated fats
• D. Hydrogenated fats

Answer: (C)

Unsaturated fats are the type found predominantly in plant-based sources and are healthier for the heart. They come in two main forms—monounsaturated and polyunsaturated fats—and are abundant in foods like olive oil, avocados, nuts, seeds, and many vegetable oils, with omega-3s from flaxseeds and walnuts also contributing. These fats help lower LDL cholesterol and triglycerides while supporting or modestly increasing HDL cholesterol, and they tend to reduce inflammation in blood vessels. This heart-friendly effect contrasts with saturated fats (more common in animal products and some tropical oils), which can raise LDL, and with trans or hydrogenated fats, which worsen cholesterol profiles and inflammation. So choosing unsaturated fats from plant sources supports better heart health.
