Sunflower Seeds 🌻

What It Is?

Sunflower seeds (Helianthus annuus) are edible seeds harvested from the center of sunflower plants. They have been consumed for centuries and are commonly eaten raw, roasted, or used in foods like seed butter and snack mixes.

Sunflower seeds provide healthy fats, protein, fiber, vitamin E, selenium, and magnesium, along with several antioxidant plant compounds. They are particularly rich in vitamin E, a powerful antioxidant that has been studied for its role in protecting cells from oxidative stress.

Sunflower seeds are best known for supporting heart health, immune function, skin health, metabolic balance, and antioxidant protection.
