Sunflower seeds are nutrient-dense, containing good amounts of protein, healthy fats (including monounsaturated and polyunsaturated fats), fiber, vitamins (such as vitamin E, B vitamins like niacin and folate), and minerals (including magnesium, manganese, copper, and selenium). They are particularly rich in polyunsaturated fats, including linoleic acid (an omega-6 fatty acid) and oleic acid (a monounsaturated fat), which are beneficial for heart health. Sunflower seeds are a good source of antioxidants, including vitamin E, which helps protect cells from oxidative damage caused by free radicals. Antioxidants contribute to overall health and may help reduce the risk of chronic diseases. Sunflower seeds are a plant-based source of protein, making them a good option for vegetarians and vegans. Protein is essential for muscle repair, growth, and overall body function.
