A new study by researchers at Temple University has shown that patients in the early to moderate stages of Alzheimer's disease could have their cognitive impairment slowed or even reversed by switching to a healthier diet.
 Healthy Diet Could Reverse Alzheimer's in Early Stages


In a previous study, researchers led by Domenico Pratico, an associate professor of pharmacology in Temple's School of Medicine, demonstrated that a diet rich in methionine could increase the risk of developing Alzheimer's Disease. Methionine is an amino acid typically found in red meats, fish, beans, eggs, garlic, lentils, onions, yogurt and seeds.

"The question we asked now as a follow-up is if, for whatever reason, you had made bad choices in your diet, is there a chance you can slow down or even reverse the disease or is it too late - that there is nothing you could do," said Pratico.

As in the previous study, the researchers fed one group of mice a diet high in methionine and another group a regular, healthy diet. After three months, they split the group receiving the methionine-rich diet into two, with one group continuing the amino-heavy diet while the second switched to the healthy diet for an additional two months.

"At the end of the study, when we looked at these mice, what we found - very surprisingly - was that switching to a more healthy diet reversed the cognitive impairment that had built up over the first three months of eating the methionine-rich diet," said Pratico.
