Which of the following foods is a source of monounsaturated fats?

Monounsaturated fats are known to be beneficial for heart health, as they can help reduce bad cholesterol levels and provide essential fatty acids. Among the options given, almonds stand out as an excellent source of monounsaturated fats. They contain a high percentage of oleic acid, which is the primary fatty acid classified as a monounsaturated fat. Additionally, almonds offer other health benefits, such as providing vitamin E, magnesium, and fiber.

In contrast, butter primarily consists of saturated fats, which can raise LDL cholesterol levels, and thus is not a source of monounsaturated fats. Soybeans, while nutritious and containing polyunsaturated fats, do not have a significant amount of monounsaturated fats relative to almonds. Potatoes are primarily a carbohydrate source and contain negligible amounts of fats. This makes almonds the clear choice when identifying a food rich in monounsaturated fats.
