Plus there's a lot of research now to show how bad these modern things for the 'weight -conscious' are.
1. A growing number of people are now fructose malabsorbant. It is posited that this may have increased because of the mucking about of sugars (eg, making high fructose corn syrup -HFCS) and how these things have been put into so many of our foods. So these people are well advised to stay away from all fake sugars, and all fructose based sugars (no honey, agave, stevia, or the mannitol/sorbitol types). And all people should avoid HFCS.
2. Aspartame is linked with a host of health problems. Google for the scariness! People with any chronic illness need to be aware of this one - esp fybromyalgia or pain syndromes.
3. "diet" drinks have been proven to INCREASE your desire for sweet things. They posit that the fake stuff without the calories short changes the calorie load that the body expects from such a taste...it doesn't get the calorie load, so it goes into 'GIVE IT TO ME NOW' mode.
4. When the fashion of 'no fat/low fat' came in (the 90s?), the food industry tried to make things taste creamy without the fat...they started using carageenan (407). Just look at your dairy products carefully, it really is in a lot of things! Unfortunately, also in the 'full fat' icecream, as it gives even more of a smooth taste. Carageenan is currently banned in food in certain European countries. Human clinical trials were about to proceed in America by the Crohns association a year or so back, as carageenan is linked to ulceration of the bowel and bowel cancer...but of course the clinical trials need to get done before govt has the impetus to dictate to the powerful food bodies.
So, as my gastroenterologist advocates, just eat the full fat, full sugar, NATURAL and 'non-mucked around with' thing. We'll all be a lot healthier. We just need to train ourselves that a small amount of it is highly satisfying!
