In terms of nutritional value, there's not much difference between a mandarin and tangerine. Both are an excellent source of vitamin C and are around 50 calories per mandarin (depends on the size). Extra fun fact: Mandarins varieties are not naturally seedless. The seeds are caused when bees pollinate the mandarin flowers.

Ounce-for-ounce, oranges and clementines have about the same number of calories, carbohydrates, protein, and fat.

Mandarins can be sweeter or slightly tangier. Both are smooth, juicy, and easy to peel. Clementines are great for snacking and desserts. Mandarins are more versatile, used in both sweet and savory dishes.
