LONDON (Reuters) – A new study reveals that a diet rich in fruits, vegetables and whole grains may not protect against Alzheimer's disease.
Scientists have long believed that this diet actually protects the brain, but the recent study of two decades has revealed no such connection.
The scientists said the study provided "compelling evidence that a healthy diet does not reduce the risk of dementia".
Researchers from the University of Montpellier followed about 8,200 healthy and non-dementia adults at the start of the study and asked them to fill out questionnaires about their diet in order to allow the experts to study. 39, evaluate the quality of their diet. Scientists continued until 2017, under the supervision of Dr. Tsenim Akbali, and divided the volunteers into three groups, depending on the health of their diet. They then compared dementia rates among the groups, but found that "there was not much difference."
Healthy eating includes the consumption of vegetables, fruits, whole grains, nuts, legumes, omega-3 fatty acids and several polyunsaturated fatty acids.
Bad foods consist of the consumption of many sweetened beverages, fruit juices, red meats, processing products, unsaturated fats and salt.
The study was sharply criticized by experts of age-related diseases because it has not been deepened.
It is known that other lifestyles are related to dementia, such as smoking.
"This study is very limited," Professor Clive Ballard of the University of Exeter would have said in the Daily Mail daily in his Sunday edition.
"The strongest evidence to date confirm the existence of some benefits to following the Mediterranean diet."
The subtle link between diet and dementia remains unclear, but the best evidence available so far suggests that a healthy diet can play a role in maintaining brain health.
