- A diet of essential amino acids could keep dementia at bayon October 22, 2021 at 9:14 pm
Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer’s disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination called Amino LP7 can hinder the development of dementia, including Alzheimer’s disease.
