Key benefits of sunflower seeds
Sunflower seeds are very high in vitamin E, which is linked to a reduced risk of heart disease. Sunflower seeds also provide antioxidant defence against cancer as well as against cataracts.

How much sunflower seeds should you eat?
Sunflower seeds are high in calories and should therefore be eaten in limited quantities. If you eat two tablespoons of sunflower seeds a day, you will double your vitamin E intake.
Hey I had to look this up for you as my boyfriend loves sunflower seeds and this is what I found…none of the sites I visited said anything about rocks. So I would say you are fine to eat them, just in moderation!!
