Is there a nutritional difference between the different color apples? I know I harp on eating your colors, so this is my test!
So, the simple stuff…the amount of carbs and fiber is the exact same between the different color apples. It only changes with the size. Remember we say that a serving of fruit is about the size of your fist. So, an apple, regardless of the color, the size of your fist, would be about 1 serving of carbs (15 grams), about 60 calories and have about 2.5-3.5 grams of fiber if you consume the skin.
All apples are largely water (about 86%), but do contain some vitamins and minerals. They contain vitamin C, K, some B vitamins, phosphorus and potassium to name a few. There are other vitamins and minerals in the apples but a very small amount.
There may be slight differences on the number of vitamins and minerals in the apples based on where they are grown but overall the differences are minimal. Red apples do actually have more Anthocyanins than green (here is where color matters). Anthocyanins are a flavonoid that may help fight cardiovascular disease, decrease the risk of cancer and help with cognitive function…most of these studies are done in animals or a small population size so unknown if it will have the same results for everyone. Overall apples are good for you and varying the color is not a bad idea!
Lastly, one literature review I found stated that they are finding that 1/3 of cancer deaths could be improved by diet! That is a strong statement and again reminding us really how important what we consume is. And remember we are what we EAT!!
