Unsaturated fats are recognized as the healthiest type of fat for heart health because they can help lower bad cholesterol levels (LDL) while simultaneously raising good cholesterol levels (HDL). Incorporating unsaturated fats into the diet can also reduce the risk of heart disease and stroke. These fats are typically found in plant-based oils, nuts, seeds, avocados, and fatty fish, which are all beneficial for cardiovascular health.

Saturated fats can raise LDL cholesterol levels, and while some recent studies suggest they may not be as harmful as once thought, they are still advised to be consumed in moderation. Trans fats are particularly detrimental to heart health as they not only increase LDL cholesterol but also lower HDL cholesterol, leading to an increased risk of heart disease. Cholesterol, while important for various bodily functions, does not inherently qualify as a fat and is primarily derived from animal products; excessive consumption can have adverse effects on heart health. Therefore, unsaturated fats hold the most significant positive impact on maintaining heart health.
