Why avoid sweets?

"The majority of sweets are made exclusively from refined sugar which has absolutely zero nutritional value. You may as well be eating cardboard. But a much greater problem of refined sugar, is that it builds up in the blood (as glucose) to such an extent that much of it is eventually stored by the body - it cannot do anything else with it! This stored glucose then transforms itself into fat and that extra fat obviously causes weight gain. The refined sugar in sweets also plays havoc with you're energy levels (giving you a quick boost followed by a huge slump) which can lead to everything from headaches and excessive perspiration to more series disorders such as Type II Diabetes."
