Raw Sunflower Seeds (In Shell)

Snacking on protein-rich sunflower seeds may help lower your blood pressure. Recent research shows that a diet with ample amounts of vegetable protein, such as the protein found in sunflower seeds, may help keep blood pressure down. A diet high in animal protein offered no such benefit in the study. Stock up on sunflower seeds, cashews, and kidney beans to get your fill of blood pressure-lowering veggie protein.
