A significant part of low carb diets is being aware of the hidden sugars in processed foods.

This page has a description of a documentary called
The Sugar Conspiracy

..........

"Regardless of how healthy or simple people tried to keep their diet, the inevitability that their kitchen pantries and fridges were stockpiled with invisible but ubiquitous sugar raised significant alarm for health professionals and government.

"But this alarm was smothered by a blanket of savvy PR tactics and multibillion dollar campaigns to silence critics of the food industry. As the investigation in the documentary The Sugar Conspiracy reveals, sugar proponents used methods similar to those employed by tobacco companies defending their products decades earlier.

"In 1967, a study into the effects of sugar on heart disease risk factors was initially funded by the International Sugar Research Foundation (ISRF). But when results showed that high-sugar diets led to higher levels of fats in the blood, the ISRF withdrew funding and insisted the results remain secret. Yudkin had also discovered a significant relationship between sugar consumption and coronary disease. His experiments convinced him that it was in fact sugar, not saturated fat that was a greater danger in raising the risk of heart disease.

"But the medical establishment continued to insist that it was fat, not sugar, that must be decreased to ensure good health. Yudkin’s assertions were labelled fictional, eccentric and unproven by fellow academics and sugar industry spokespeople."
