Sugar - A startling new truth

Back in 2009 Dr. Robert Lustig gave a lecture called: ‘Sugar, the bitter truth’ this was posted to youtube a year later and was a scientifically heavy 1.5 hour long video that you’d think not many people would sit through. But this video went viral gaining over 1,000,000 viewers. Packed with amazing research and biochemistry Dr. Lustig argued that a calorie is not a calorie.

In short, your body handles 120 calories in two slices of white bread very differently to 120 calories in a can of soft drink or beer. Dr. Lustig’s particular area of expertise is childhood obesity. Back in the 70s it was argued that our high fat diets were making us fatter which has been the prevailing wisdom for the past 30 years - but what everyone had overlooked that our diets were much higher in sugar - particularly fructose.
To cut a long lecture very short, the body uses up glucose very efficiently (sugar found in bread etc.), but turns most of the calories found in fructose and glucose into fat. The big problem is high fructose corn syrup which is found in just about everything. Basically, he argues, if you cut out the fructose you’ll cut out the fat which is why the Atkins and Japanese diets work so well - they’re very low in sugars. There’s more to the lecture than ‘fat’ - he demonstrates how sugar/fructose create problems like diabetes, hypertension etc. all diseases that have also increased since the 70s.
