(HealthDayNews) -- Did anyone ever tell you not to peel carrots? They probably said all of the vitamins were near the surface, and you would be trashing the best part.
The same may apply to citrus fruits, the Journal of Nutrition reports.
New research indicates that the monoterpenes in citrus fruit -- the oils that give oranges and lemons their special smell -- may help prevent skin, liver, lung and stomach cancers. But these oils are found mostly in the peel.
Trouble is, the Purdue University study yielded no clues on how to get used to the bitter taste of an orange peel.
