It doesn't process it that differently really.MonStar said:I still don't understand how your body processes bananas any different than oranges or apples. Doesn't make sense to me at all.![]()

I don't know if I would agree with you here.Jodi said:Fruits only fill liver glycogen, not muscle glycogen and it doesn't take much fructose to fill your liver. If you eat too much fructose you spill over, spilling over means turning to fat.
Nate said:regarding GI, i thought this was an interesting read.
BulkMeUp said:Interesting discussion on fruits, as i love fruits. However unless one is training for a competition, would it really make such a difference if one consumes 2-4 pieces/servings a day?

An overly simple statement there....joey2005 said:but all in the end...it doesnt help fat loss...only hurts it ..
Emma-Leigh said:Pahhh... That study was flawed...
I never said it was. I love fruit and eat it all the time but I do not see the need for more than a few pieces per day especially while on a cutting diet.ikam said:That's an oversimplified explanation. Fruit is not as evil as it is made out to be.
I don't know if I would agree with you here.
Fruits are not just fructose - they also haven variable amounts of sucrose, glucose and starches and so they will also serve to replenish muscles to some degree... Sure, they will help fill liver glycogen, but it is not an 'either/or' event like everyone seems to believe.
They will also only fill liver glycogen stores if the body is not in need of energy - so if your blood glucose levels are low (like following exercise, or when on a calorie restricted diet) the body will prioritise the energy from the fruit and convert the fructose straight to glucose in the liver, which would then be released into the blood as available energy for the body. The body is pretty good at meeting it's needs and it will not 'hoard energy' in the liver if your brain/body needs the fuel.
Also - the average serve of low-calorie fruit (apples, berries etc) only have 3 to 5g of fructose and even higher-calorie fruit (such as pears and banana's) only have about 10g. So at a maximum you are only getting 40 calories from fructose... Which is not a lot of energy at the end of the day. This is especially relevant if you consider the average human liver has the capacity to store ~ 80 to 100g of glycogen - which is ~ 320 to 400 kcal in energy...
So, if you get, say, 40 cals from 'fructose' and then (as it takes energy to form glucose and then glycogen), you use a few cals for the process of conversion, you can see that you need a lot more energy than you would get from a piece of fruit (or even a few pieces of fruit) to fill your liver stores completely... Especially if you consider that, while dieting, your liver glycogen stores are going to be significantly lower than normal anyway...
