지방 (Fat) is a type of nutrient that provides energy to the body. It is one of the three main macronutrients, along with carbohydrates and proteins. Fats are essential for various bodily functions, including hormone production and the absorption of fat-soluble vitamins like vitamin A, D, E, and K. There are different types of fats, including saturated, unsaturated, and trans fats. Unsaturated fats, found in foods like olive oil and avocados, are considered healthier options. In contrast, trans fats, often found in processed foods, can be harmful to health when consumed in excess.
