Howdo you determine because they are all different sizes..by weight or my length?

I know that a tomato is a fruit and banana a herb ;D

My 13month old son is obsessed with eating bananas, like a lil monkey, lol. He is eating at least 3 whole bananas by himself a day and I am afraid to let him eat any more than that, which I am sure he would. Is there any danger in letting him eat bananas, like an overdose in potassium or anything that I need to be worried about?
He eats all kinds of fruits and veggies all day… So its not just the bananas…. he loves peaches and pears, strawberries, kiwi, apples, tangerines, but he just freaks out when he can’t get a banana, even if he sees them at Walmart, lol.

Bananas are indeed very healthy not to mention their high potassium content which is good for the body. I heard from a friend that ripe bananas has high sugar content and that "saba" bananas contain less sugar. Could anyone also confirm this. Thanks a lot.

(sorry for my bad english)
how about getting potassium from banana??

one question again, can potassium chloride be subtituted by sodium chloride for general purpose (i want to get chlorate from potassium chloride. and i want to substitute potassium chloride with sodium chloride)???

is it true that a banana has 100 calories, my fried said it but i dont beoleive it. it is true and how is it true or other way round =]
