Is a high-protein diet good for us? This may shrink the brain (mice) according to Netdoctor news But, this may give us a good reason for eating more fruit, vegetables and fish.
A high-protein diet appears to lead to a smaller brain in mice, according to a new study in the journal Molecular Neurodegeneration. Researchers tested four different diets in mice with Alzheimer’s disease. They found that animals which received a high-protein, low-carbohydrate diet typically had brains that were five per cent lighter than those on other dietary regimes. In addition, these mice showed poor development in some regions of the hippocampus – an area of the brain that is one of the first to be damaged in people with Alzheimer’s disease.
Lead author Professor Sam Gandy, from the Mount Sinai School of Medicine in New York City, commented: ‘One wonders whether particular diets, if ingested at particular ages, might increase susceptibility to incidence or progression of Alzheimer’s disease.’
Dr Susanne Sorensen, head of research at the Alzheimer’s Society, said that further research is needed to better understand the links between diet and dementia risk. In the meantime, she said that ‘it is important to eat a diet rich in fruit, vegetables and fish’.
