Several large studies suggest that the monosaturated fat in olive oil is good for the heart. Olive oil lowers bad cholesterol levels and increases good cholesterol. It is high in antioxidants–and is one of the superstars of the Mediterranean diet. Recent research shows that heart-attack survivors on a Mediterranean diet had half the death rates of those on an ordinary low-fat diet.
The caffeine content in tea is useful for stimulating alertness, mood and motivation, but is also a rich source of the antioxidant called catechins. Studies suggest that catechins protect the artery walls against the damage that causes heart disease and prevents formation of blood clots. It also does wonders for the spirit on a cool autumn day.

Red Wine or grape juice
Grapes provide vitamin C, vitamin B1 and vitamin B6–red grapes also contain powerful phytochemicals (especially phenolics) that may help decrease risk of cardiovascular disease. These phenolic compounds are housed mostly in the skin of the red grapes, which is what makes red wine red and dark grape juice red or purple. Resveratrol, a polyphenolic stilbene found in the skins of red fruits including grapes, may be responsible for some of the health benefits ascribed to the consumption of red wine. Resveratrol has been shown to have anti-oxidant, anticancer, and anti-inflammatory activity.
