Fats and oils are crucial macronutrients that provide a concentrated source of energy, essential fatty acids, and aid in the absorption of fat-soluble vitamins (A, D, E, and K). Fats are typically solid at room temperature, while oils are liquid, both derived from animal and plant sources. Healthy fats, such as those found in avocados, nuts, seeds, and olive oil, can support heart health and reduce inflammation, whereas trans fats and excessive saturated fats, often found in processed foods, can increase the risk of chronic diseases. Incorporating healthy fats into the diet is important for maintaining overall health, promoting brain function, and supporting cellular growth and hormone production.
