Yağlar, or fats, are essential nutrients that provide energy and support cell growth in the body. They are classified into different types, including saturated, unsaturated, and trans fats. While some fats are beneficial, such as those found in avocados and nuts, others, like trans fats found in processed foods, can be harmful to health. In addition to energy, yağlar play a crucial role in absorbing vitamins A, D, E, and K, which are vital for various bodily functions. Consuming a balanced amount of healthy fats can contribute to overall well-being, while excessive intake of unhealthy fats may lead to health issues like heart disease.
