What type of fat is considered beneficial for heart health?

Unsaturated fat is considered beneficial for heart health because it can help reduce levels of LDL cholesterol, often referred to as "bad" cholesterol, in the bloodstream. This type of fat is typically liquid at room temperature and is found in foods such as avocados, olive oil, nuts, and fatty fish. Unsaturated fats, which include both monounsaturated and polyunsaturated fats, are associated with a lower risk of heart disease when they replace saturated and trans fats in the diet. They contribute essential fatty acids and are important for overall health, including inflammation reduction and improved cholesterol profiles.

In contrast, saturated fats are typically found in animal products and certain oils and can raise cholesterol levels. Trans fats, often present in processed foods, have been linked to increased heart disease risk and are generally advised to be avoided. Cholesterol is a waxy substance found in the body and in certain animal foods, but it is not classified as a fat type contributing positively to heart health in the context of dietary fats. Hence, unsaturated fat is the most beneficial type of fat for promoting heart health.
