Amidst all the recent goings-on about sugar, I decided to see what in the world the anti-sugar people are going on about, especially when claims that sugar ages you came up. I found out there is research into something called Advanced Glycation End products (which makes AGEs a convenient acronym) and thought this would make an interesting discussion.
From here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3704564/
Modern diets are largely heat-processed and as a result contain high levels of advanced glycation end products (AGEs). Dietary advanced glycation end products (dAGEs) are known to contribute to increased oxidant stress and inflammation, which are linked to the recent epidemics of diabetes and cardiovascular disease.
This isn't about sugar per se since sugar is neither demonized nor singled out in the article but rather it discusses things like how AGEs are produced depending on food type and cooking method, amongst other related information.
