About to ask a bad question about apples

Apple (1 medium) VS Banana (1 medium)

Sugar (16g) ....... Sugar (20g)
Dietary Fiber (3g) ...... Dietary Fiber (4g)
Vitamin C (8%DV) .... Vitamin C (15%DV)
Total carbs (22g) ..... Total carbs (29g)



Ok my question is since 1 Banana has more dietary fiber, vitamin C, and just 4 more grams of sugar then an apple............How is it possible that a apple has a drastically lower scale on the GI?

The banana has more fiber
The banana has more vitamins
They both have the same amount of water
Bananas have just 4 grams more of sugar.......I don't see how apples could be so much lower in the GI scale then 1 banana. The nutrient makeup does not support that.

Also, I want to point out that 8% of Vitamin C in an apple if really not a lot of vitamin C.....I always thought that apples had much more vitamin C.

If you look at the sugar profiles of apples and bananas, an apple has a greater amount of fructose than a banana. The fructose to glucose ratio of an apple is about 2:1 whereas the fructose to glucose ratio of a banana is about 1:1. Also the sugar to fiber ratio of a banana is about 9:1, whereas for the apple, it is about 7:1.

Those would be my guesses for the higher GI of bananas than apples. It the end, it probably is not a matter of great concern. The GI of a banana is 52. The GI of an apple is 38. That is not a significant difference in my opinion. I don't know why bananas and fruit in general are shuned in the dieting world. Most are relatively low on the GI scale, and they are all highly nutritious.

Bananas have a higher glycemic load, aside from just being a bit higher on the Glycemic Index.

A lot of reasons go into it's digestive properties. The thing with bananas, mostly due to it's substance - dictating how the body processes it goes into it's rating on the GI scale. It's shunned in diets because it's glycemic load categorizes it as a fruit that causes a greater insulin spike, which is something most people try to avoid.

I should look into this Glycemic Index, shouldn't I?

Hey, I'm new. Insulin spikes... for every action there's an opposite and equal reaction? What goes up, must come down?

I eat plenty of carbs. I guess that would be helpful info. If so, how?

It's the digestive properties. It takes longer to digest an apple than it does a banana.
BTW It takes more calories to process / digest an apple then there are in the apple. Negative calorie food or something like that.
