Now Too Much Protein Could Be Harmful

Research suggests that high protein diets can shrink brain and might cause Alzheimer’s. The study shows that mice fed with meals containing high proteins similar to those of the original Atkin’s diet had 5% lighter brains than others.

Those mice with the high protein diets also had a slightly less developed Hippocampus part of the brain. Hippocampus is the memory related part.

These findings published in the journal Molecular Neurodegenaration suggests slowing dementia through better eating. The mice were given different diets: regular, high fat / low carb, high protein / low carb, high carb / low protein. The comparison was drawn on the basis of brain and body weights as well as plaque build up associated with Alzheimer’s.

Professor Sam Gandy, Neurologist, Mount Sinai School of Medicine in New York, said, "The most unexpected result of our study was the loss of overall brain mass associated with a high protein-low carbohydrate diet”. This serves a huge blow to the followers to the Atkin’s diet.

Another study correlated that Amyloid Precursor Protein (APP), associated in the development of Alzheimer’s, plays a critical role in brain development. The study done by Georgetown University Medical Centre suggests the criticality of APP balance.

The study was done by comparing the spinal density in genetically modified mice that don’t or over produce APP. They found decreased spine density in the former whereas in the latter was present increased spinal density.
