Fat is a type of nutrient that our bodies need for energy and to support various functions. It helps protect our organs, keeps our skin healthy, and aids in the absorption of certain vitamins, like vitamin A, D, E, and K. There are different types of fat, including saturated fat, unsaturated fat, and trans fat, each having different effects on our health. While fat is essential, it's important to consume it in moderation. Eating too much unhealthy fat, especially trans fats, can lead to health issues like heart disease. Choosing healthier fats, such as those found in avocados, nuts, and olive oil, can help maintain a balanced diet.
