If you’re confused about which vegetables are best for your heart, seeing red can give you a clue. Researchers found that men with high blood levels of the reddish plant pigment lycopene seem less prone to coronary heart disease then those with low levels of the red pigment.

Lycopene is an antioxidant that is thought to play a part in inhibiting the development of atherosclerosis, the narrowing and hardening of the arteries that can lead to coronary heart disease. In men, those with the lowest amounts of lycopene had the most advanced atherosclerosis. There was no similar correlation among women; the researchers suggested that might be because they had higher levels of various antioxidants in their bloodstream.

So – all you guys – be sure to eat plenty of tomatoes, with their juices and sauces, as well as watermelon, guavas, and red berries.
