For some time the Alzheimer’s and obesity connection has been known, but exactly why there is a connection has eluded researchers.

Recent research in Melbourne, Australia, indicates that the obesity/Alzheimer’s connection could be the result of a build up of protein – beta amyloid – in the brains of obese people. The beta amyloid buildup is caused by an increase in the amount of the bad cholesterol LDL, which is common among obese individuals. This is a significant insight because the build up of beta amyloid produces a neurotoxin which kills brain cells. Simply put, the build up of beta amyloid creates an enzyme that generates hydrogen peroxide—the result is that your brain is bleached!

The bleaching interferes with the production of dopamine and leads to the development of Alzheimer’s disease.

Reducing the amount of excess weight reduces the level of the bad cholesterol (LDL), while increasing the level of good cholesterol (HDL). As a result, losing the weight is a major step in avoiding the onset of Alzheimer’s disease. One of the best things a person can do to reduce their chances of developing Alzheimer’s disease is to engage in physical activity, like walking or exercise.
