Excellent piece and very pleased to see 60 Minutes tackle such a difficult subject. Thank you for breaking through what many of us have been trying to tell our dietitians and physicians for years: The 60+ carbohydrate percent recommended by the so-called Food Pyramid/Plate and the USDA is patently incorrect.

If I may make a few corrections, your piece says that all cells REQUIRE glucose. This is incorrect! ONLY axons of certain neurons and rapidly acting fast twitch muscles require glucose. Indeed, this is why glucose needs are actually so minimal and why sugars are not essential compounds! Ketones (which are natural breakdown products of fats) are utilized more efficiently by all cells except those listed above. In particular cardiac cells prefer ketones for efficiency over glucose.

Second, while I agree with Dr. Lustig that fructose is a particularly bad player, excess glucose enters into the same pathway that fructose does and causes the same damage. Thus, the pastas and the breads, which are all converted to glucose, worsen the damage by the added sugar.

Third, glucose is addictive as indicated in your piece. Thus you have to deal with your addiction. The conclusion that you can have “some” sugar is therefore not a good recommendation. It IS a good start to the final recommendation to stop eating sugar! Isn’t this akin to saying to a cocaine addict that “some” cocaine is OK?

Stimuli such as advertisements can override your brains’ signal that you are satiated. This means that the advertisement of sugary cereals on Saturday mornings is, in addition to the aforementioned addictions, causes overeating of such sugary cereals and is a great contributor to childhood obesity. The pizza commercial precisely at 5:15 pm invokes the phone call to the local pizza chain. The link of television watching and obesity is now clear: Such advertisements directly increase eating behaviors.

Perhaps as a follow-up, 60 Minutes might ask the following question: Why does the USDA continue to support the now debunked Food Pyramid/Plate? Answering that question might get you into a 100 billion+/year industry that encompasses not only lobbyists for food and soda industries, but also the diet and fitness industry, bariatric and plastic surgeries industries, pharmaceutical industries, advertising agencies and anything that makes money on our human physiological vulnerability to sugars and its direct link to obesity.
