9. Watermelon

Watermelon has a high amount of the amino acid L-citrulline which helps unclog arteries. Studies suggest that short-term L-citrulline supplementation may functionally improve arterial stiffness. Watermelon is also a natural source of nitric oxide, which the heart needs for lowered blood pressure.

10. Asparagus

Asparagus is loaded with vitamins B1, B2, C, E, K, fiber, and minerals, all of which contribute to a healthy cardiovascular system and help to unclog arteries. Asparagus boosts the production of glutathione which helps prevent toxic substances from oxidizing in the arteries. Asparagus also contains alpha-linoleic acid and folic acid, which help to reduce the hardening of blood vessels. Last but not least, this superfood also can help lower blood pressure.
