Nonsense. Sugars have been eaten for centuries. Ignore these diet alarmists. They are most always wrong.

Agreed. Age seems to be a contributing factor and from the Mayo clinic:
Type 2 diabetes develops when the body becomes resistant to insulin or when the pancreas stops producing enough insulin. Exactly why this happens is unknown, although genetics and environmental factors, such as excess weight and inactivity, seem to be contributing factors.
The causes of Type 2 are known, especially the continuously high insulin levels produced by crappy post-industrial diet. See Dr. Joseph Kraft and his insulin-assay analysis. You get insulin-resistant in the continual presence of high insulin levels.
The answers are well-known also: lower your insulin requirements by eating the right foods at the right times. For most this means some type of intermittent or periodic fasting. Go longer times without food. See Dr. Jason Fung for a more complete explanation.
