Would you please provide some more information on this? I have never heard of any such correlation.
off course, that i know there are other studies that are testing this hypothesis but (high intake of BCAA= ALS) the already data are pretty worrying:
some STUDIES that i read
(for some reasons i cannot write the copy the link; once i did and submit is not complete??)

BCAA and high mortality in people already having ALS
Branched-chain amino acids and amyotrophic lateral sclerosis: a treatment failure? The Italian ALS Study Group.
We initiated a double-blind, placebo-controlled trial to test the efficacy and safety of branched-chain amino acids (BCAA) (L-leucine 12 g, L-isoleucine 6 g, and L-valine 6 g daily) in amyotrophic lateral sclerosis (ALS) patients. There was an EXCESS OF MORTALITY in subjects randomized to active treatment (24 BCAA, 13 placebo) when a total of 126 ALS patients had been recruited. This finding, associated with the lack of efficacy of BCAA (measured by comparing the disability scales in the two treatment groups), led the Data Monitoring Committee to require CESSATION of the trial.

I am confused by your conclusions. Doesn’t this (limited)study indicate there might be a correlation between higher mortality rates with patients who already have ALS taking BCAAs? I don’t see how you came to the conclusion that high intake of BCAA=ALS.
