Which categories are included under unsaturated fats?

Unsaturated fats are categorized into two main types: monounsaturated fats and polyunsaturated fats. This classification is based on the chemical structure of the fat molecules.

Monounsaturated fats contain one double bond in their fatty acid chain, which makes them more flexible and less solid at room temperature compared to saturated fats. Common sources include olive oil, avocados, and nuts.

Polyunsaturated fats have more than one double bond in their structure and include essential fatty acids, which the body cannot produce on its own. These fats are found in foods like fish, walnuts, and sunflower oil.

Understanding these categories is important because unsaturated fats are generally considered healthier than saturated and trans fats, as they can help lower bad cholesterol levels and reduce the risk of heart disease.
