Which of the following is a common seed known for its polyunsaturated fat content?

Sunflower seeds are well-known for their high content of polyunsaturated fats, particularly omega-6 fatty acids. This type of fat is crucial for heart health and can help lower cholesterol levels when used to replace saturated fats in the diet. Sunflower seeds also provide a good source of vitamin E and other beneficial nutrients, making them a nutritious choice for health-conscious individuals.

In contrast, while chia seeds do contain healthy fats, their primary fat content is predominantly omega-3 fatty acids, which are different from the polyunsaturated fats emphasized in the question. Sesame seeds are mostly known for their content of monounsaturated fats and lignans, which provide antioxidant benefits but do not have the same profile as polyunsaturated fats. Poppy seeds, while nutritious, have a lower fat content overall and do not prominently feature polyunsaturated fats compared to sunflower seeds. The focus on sunflower seeds highlights their status as a rich source of these beneficial fatty acids.
