you can try a little experiment: Saliva contains amylase, which breaks down Cooked starch to maltose.
keep a bit of water biscuit in your mouth, tucked inside your cheek. After a few hours, you will taste the sweet maltose. Try again with unprocessed grains and the change won't happen.
the amylase in the small intestine isn't very different from that in the mouth.So digestion of uncooked starch doesn't take place there either.
Very true , BUT chew up the whole grain and keep this in your mouth and you will find that maltose will be released try swallowing some sweetcorn , what happens it goes through you totally undigested , but chew it and you can get the nutrients out .
There were some very interesting studies on rats in New Scientis a while ago which showed that animals fed highly processed foods got fat easily , whereas those on very unprocessed foods didn't , this even equated to whether the food was whole for example whole carrots or grated carrots and the ones fed just chopped up ones were intermediate .
