Which type of fats is described as healthy?

• A. Saturated fats
• B. Trans fats
• C. Unsaturated fats
• D. Cholesterol

Answer: (C)

Healthy fats are those with double bonds in their fatty acids—unsaturated fats. These kinked chains keep the fats liquid at room temperature and tend to improve blood cholesterol profiles, primarily by lowering LDL cholesterol when they replace saturated and trans fats in the diet. They come in two main types: monounsaturated fats (olive oil, avocados, many nuts) and polyunsaturated fats (fatty fish, seeds, most vegetable oils). In contrast, saturated fats have no double bonds, are often solid at room temperature, and can raise LDL cholesterol; trans fats, created by hydrogenation, raise LDL and lower the protective HDL, making them particularly harmful. Cholesterol isn’t a fat, but a lipid molecule; its dietary impact varies and isn’t described as a healthy fat type. So, the healthy type described is unsaturated fats.
