Indian market packs often salted (400mg sodium added)—choose unsalted for hypertension control. Phytosterols (281mg) qualify FDA heart-health claim.

How many calories and macros in 1 oz sunflower seeds?

Exactly 165 calories per ounce (28g) dry-roasted kernels: 14g fat (72% calories), 7g carbohydrates (3g fiber = 4g net), 5.5g protein (13% calories).
