In the United States, the term "sweet pepper" encompasses a wide variety of mild peppers that, like the chile, belong to the Capsicum family. Sweet peppers can range in color from pale to dark green, from yellow to orange to red, and from purple to brown to black. Their color can be solid or variegated. Their usually juicy flesh can be thick or thin and the flavors can range from bland to sweet to bittersweet. The best known sweet peppers are the bell peppers, so-named for their rather bell-like shape. Sweet peppers are an excellent source of vitamin C and contain fair amounts of vitamin A and small amounts of calcium, phosphorus, iron, thiamine, riboflavin and niacin.
