Everyone loves color and especially it is bright orange, on top of their cake, pies, tart, or just eating under the winter sun.

The other nutrients include calories 47, carbs 11.7 grams, fiber 2.4 grams, protein 0.9 grams, fat 0.1 grams, vitamin A 4% of daily value (DV), vitamin C 89% DV, folate 8% DV, and potassium 5% DV. TangerinesThey were first grown in Palatka, Florida and received the name tangerine because they were imported through the city of Tangier in Morocco.The water content in this too is also high, up to 85% and carbs up to 4% and almost no fat. The nutrient composition is as followed calories 53, carbs 13.3 grams, fiber 1.8 grams, protein 0.8 grams, fat 0.3 grams, vitamin A 14% DV, vitamin C 44%, folate 4% DV and potassium 5% DV.The main difference between the two apart from their texture is that orange is richer in vitamin C and has less calories as compared to a tangerine.
