The fiber in sunflower seeds could help address blood sugar levels and possibly enhance insulin sensitivity, which is crucial for reducing the risk of insulin resistance seen in metabolic syndrome. Vitamin E in sunflower seeds acts as an antioxidant, shielding cells from oxidative damage linked to metabolic disorders.

  8. It Might Support Weight Management

    The filling nature of fiber and the satiating levels of fat and protein in sunflower seeds could help you manage your weight effectively. The presence of chlorogenic acid in sunflower seeds may provide antioxidant and anti-inflammatory effects that might contribute to weight management. According to a study, taking 500 mg/day of SUN-CA, which includes 100 mg of chlorogenic acids, for 12 weeks improved the reduction of excess body fat in adults with weight issues.

    Sunflower seeds have iron, which makes hemoglobin for carrying oxygen in red blood cells. Thus, including these seeds may help you gain enough iron to prevent anemia caused by iron shortage. Vitamin E in sunflower seeds could act as a shield, protecting red blood cells from damage that may make your anemia worse. Adding sunflower seeds to your diet could help treat anemia by giving your body essential nutrients that might help make healthy red blood cells.
