Saturated fats are types of fats that have no double bonds between carbon atoms. They are typically solid at room temperature and are commonly found in animal products like butter, cheese, and meat, as well as some plant oils like coconut oil. Consuming too much saturated fat can raise cholesterol levels, potentially increasing the risk of heart disease. Unsaturated fats, on the other hand, contain one or more double bonds in their structure. They are usually liquid at room temperature and are found in foods like olive oil, avocados, and nuts. Unsaturated fats are considered healthier for the heart and can help lower bad cholesterol levels when used in place of saturated fats.
