Dietary fat is a type of nutrient that provides energy and supports cell growth. It is essential for absorbing certain vitamins, such as vitamin A, D, E, and K, which are fat-soluble. Fats can be classified into three main types: saturated, unsaturated, and trans fats. Unsaturated fats, found in foods like olive oil and avocados, are generally considered healthier than saturated fats, which are found in animal products. While fats are important for a balanced diet, consuming them in moderation is key. Excessive intake of unhealthy fats, particularly trans fats found in processed foods, can lead to health issues such as heart disease. It's important to choose healthier fat sources and maintain a balanced diet for overall well-being.
