They call Alzheimer’s “type-3 diabetes” – because it’s caused by junk food.
Guardian reports on the growing body of evidence that Alzheimer’s disease comes from what we eat – that the senility disease might actually be caused by junk food:
About 35 million people suffer from Alzheimer’s disease worldwide; current projections, based on the rate at which the population ages, suggest that this will rise to 100 million by 2050. But if, as many scientists now believe, it is caused largely by the brain’s impaired response to insulin, the numbers could rise much further. In the United States, the percentage of the population with type 2 diabetes, which is strongly linked to obesity, has almost trebled in 30 years. If Alzheimer’s, or “type 3 diabetes”, goes the same way, the potential for human suffering is incalculable.
The association between Alzheimer’s and type 2 diabetes is long-established: type 2 sufferers are two to three times more likely to be struck by this form of dementia than the general population. There are also associations between Alzheimer’s and obesity and Alzheimer’s and metabolic syndrome (a complex of diet-related pathologies).
Researchers first proposed that Alzheimer’s was another form of diabetes in 2005. The authors of the original paper investigated the brains of 54 corpses, 28 of which belonged to people who had died of the disease. They found that the levels of both insulin and insulin-like growth factors in the brains of Alzheimer’s patients were much lower than those in the brains of people who had died of other causes. Levels were lowest in the parts of the brain most affected by the disease.
