Diet fix eases Huntington’s symptoms in mice

Dietary supplement improves health of rodents with mutation that causes neurodegeneration

Huntington’s disease robs a person of a healthy mind and body. A simple dietary fix may guard against the theft, which currently can’t be stopped or slowed with treatments, a study suggests. Mice carrying a mutation similar to that in people with Huntington’s disease showed improvements after eating a diet rich in cysteine, a simple amino acid commercially available as a dietary supplement, scientists report March 26 in Nature.
