Coffee

Research has found that not only is coffee not bad for your heart, it might actually be beneficial.

Coffee doesn't look or taste anything like a salad, but it contains some of the same benefits.

Bad news if you love your French press, or if you're a fan of Turkish or Scandinavian boiled coffee: Unfiltered brews contain a compound called cafestol that can raise your "bad" LDL cholesterol levels, says van Dam. Cafestol is also found in smaller but still noteworthy amounts in espresso, as well as in coffee made in a moka pot.

While coffee can be a good-for-you option, that changes if you add the wrong things. There's a big difference between a cup of coffee served black and a fancy concoction that contains a liberal pour of sugary syrup or heavy cream, or copious amounts of sugar.

Research shows that coffee doesn't appear to raise your risk of developing or dying from cancer, and some studies suggest that coffee drinkers even have a slightly lower risk of certain types of cancer, such as cancer of the liver or the endometrium (the lining of the uterus).
