High-fat foods are items that contain a significant amount of fat, which is one of the three main macronutrients, alongside carbohydrates and proteins. These foods can be classified into different types of fats, including saturated, unsaturated, and trans fats. Common examples of high-fat foods include avocados, nuts, olive oil, and butter. While fats are essential for the body, providing energy and supporting cell growth, consuming them in moderation is important. Some high-fat foods, like fatty fish and seeds, offer health benefits, while others, such as processed snacks and fried foods, may contribute to health issues if eaten excessively.
