Which fruits and vegetables should be eaten regularly to get vitamins?

apples and lemons are good. But other fruits like kiwis are better for you than oranges. Kiwis are one of the super fruits. Banana's are excellent as well as blue berries. Blue berries have tones of antioxidants/vitamins and help prevent cancer and heart disease they also help clean out your arteries.
You also cannot go wrong with tomatoes, grapes or cherries. My favorite website for health stuff is LiveStrong.com. It's one of the best sites in my opinion.

Lemons Are Good, but you can try lots of different vegatebles and fruits.
