This is going to be a pretty short post to help people understand what the basic difference between simple and complex carbs. To put it even more simply lets look at is as refined vs unrefined. To understand this you will need two pots of water, 1 slice of bread, 2 shells of pasta (white/wholewheat/wholegrain-its all the same mess), a head of broccoli and a carrot.
Bring both pots of water to the boil. Drop the pasta and the bread in one pot and the veg in the other. Leave for 10 minutes with the lid on and come back. keep the lid on. take them off the heat and let sit for 10 minutes. open the lid.
On one side you will see that the carbs have broken down easily and on the other you will see them still in tact. Equal amounts of energy have been spent on both but only one trys to hd onto to its energy. One will flood the system with its potential energy while the other will take its time to give up its energy and nutrients.
It seems that because we live in a world that is fast paced we believe we NEED to consume food as fast as possible we go for the mess in the pot and not for the coloured good food.
Think about it next time before you eat a sandwich.
