Atkins Diet May Shrink Brain and Boost Alzheimer's Risk

Atkins Diet May Shrink Brain and Boost Alzheimer's Risk

High-protein diets may shrink the brain as well as the waistline, raising the risk of Alzheimer’s disease in later life.

In tests, the brains of mice fed Atkins-like diets, rich in protein and low in carbohydrate, were five per cent lighter than those of other creatures.

Importantly, areas key to memory were underdeveloped.

Although it is unclear if high protein diets have the same effect in people, it is already known that low-fat diets packed with fruit and vegetables, cut the risk of dementia.

The US researchers said that looking at how different nutrients affect human brain health could lead to new ways of staving off the disease that affects 400,000 Britons.

With the number of sufferers expected to double within a generation, any method of cutting the number of cases could have a huge impact on public health.

Sam Gandy, a leading expert on Alzheimer’s disease, looked at the effect of various diets, including one high in protein and low in carbohydrate on the brains of mice.

The creatures had been genetically-engineered to make amyloid-beta, the poisonous plaques blamed for brain cell death and memory loss in Alzheimer’s.

Those given high-protein foods had lighter brains than other animals, the journal Molecular Neurodegeneration reports.

Interestingly, they did not have more plaques than the other animals.

It is thought that large amounts of protein may make the brain more vulnerable to the poisonous effect of the plaques, speeding up cell death.

Dr Gandy, of the Mount Sinai School of Medicine in New York, says research into the effects of protein on people is now vital.

‘This would be a challenging undertaking but potentially worthwhile if there is a real chance that the ravages of Alzheimer’s disease might be slowed or avoided through healthy eating,’ he said.

‘Such trials will be required if scientists are ever to make specific recommendations about dietary risks for Alzheimer’s disease.

    This is a very interesting braineffect, thank God for the medical research. If we keep discovering things in this rhythm there are high chances that we discover the actual cures for these diseases.

    Wow, as popular as that fad diet was/is there will be a lot of dementia in folks in the coming years!
