I first heard of a possible link between sugar beets and multiple sclerosis in Dr. Stephanie’s Seneff talk on Glyphosate substituting for Glycine as a possible risk factor for autism…
She gave another example in talk and in slides where the Aze (azetidine-2-carboxylic acid) in sugar beets can incorrectly substitute for proline, affecting myelin synthesis (which has implications to Multiple Sclerosis).
While this is not a common well-known idea. The paper Misincorporation of the proline homologue Aze (azetidine-2-carboxylic acid) into recombinant myelin basic protein supports this idea by stating …
“the worldwide distribution of MS correlates with high rates of sugar beet production … severe neurodegeneration has been observed in sheep, including pregnant ewes, fed a diet rich in beet by-products (Chalmers, 1974). Rubenstein hypothesises that the misincorporation
of Aze (1) into proteins during brain development may contribute to inherently unstable myelin, which may be one of many factors predisposing an individual to developing MS”
For a healthy person, I don’t think eating beets in moderation is a problem. The effects mentioned is likely to have a very little effect, unlike you unreasonably overdo the beets thing.
