Fats are an essential nutrient that provide energy, support cellgrowth, protect organs, and help the body absorbnutrients. They are also important for brain function and hormone production. Fats are a type of lipid, along with oils and waxes. There are different types of fats, including saturated fats, unsaturated fats, and trans fats.
Types of Fats
Saturated fats: These fats are typically solid at room temperature and are found in animal products such as meat and dairy, as well as in some plant-based oils like coconut oil and palm oil. Eating too much saturated fat can increase cholesterol levels and the risk of heartdisease.
Unsaturated fats: These fats are typically liquid at room temperature and are found in foods like avocados, nuts, seeds, and fish. Unsaturated fats are considered healthier than saturated fats and can help lower cholesterol levels and reduce the risk of heartdisease.
Trans fats: Trans fats are created through a process called hydrogenation, which makes them solid at room temperature. They are found in many processed and fried foods and are known to raise cholesterol levels and increase the risk of heartdisease.
Functions of Fats
Some important functions of fats in the body include:
While fats are essential for the body, it's important to consume them in moderation and to choose healthier sources of fats, such as avocados, nuts, and fish, over processed and fried foods. Reading food labels can help identify the types of fats present in packaged foods, and aiming for a balanced diet that includes a variety of nutrients is key to maintaining overall health.
