SAN DIEGO — A food plan low within the amino acid glutamate might ease migraines, a small research suggests. A month of staying away from high-glutamate meals led to fewer migraines in a bunch of 25 folks with Gulf Struggle Sickness.
The specifics of those veterans’ migraines, a part of a set of signs ensuing from the Gulf Struggle, might differ from these of different individuals who endure from migraines. But when the underlying relationship between glutamate and migraines is analogous, the food plan might assist the estimated 1 billion folks worldwide who’ve migraines.
Present medicine for treating migraines, together with a brand new class of compounds that block a chemical messenger known as CGRP, may help. However current medicine don’t work for everybody, says neuroscientist Ian Meng of the College of New England in Biddeford, Maine. A dietary change might be a low-risk and accessible option to deliver reduction.
Glutamate is each a sign that excites nerve alerts within the mind and an amino acid present in tomatoes, processed meats, aged cheese, mushrooms and, after all, monosodium glutamate, or MSG. For a month, 25 veterans of the Gulf Struggle ate a low-glutamate food plan stuffed with entire fruits and veggies and averted high-glutamate meals together with soy sauce, mushrooms and ultraprocessed meals.
Earlier than this food plan, 64 p.c of those folks reported having a migraine within the earlier week. After a month of a low-glutamate food plan, that quantity dropped to about 12 p.c, neuroscientist Ashley VanMeter stated November 16 in a information briefing on the annual assembly of the Society for Neuroscience. After the one-month food plan ended, 88 p.c of the folks within the research selected to stay on the food plan. “They really feel that [the diet] is certainly benefiting them,” stated VanMeter, of Georgetown College in Washington, D.C.
Accompanying mind scans confirmed that a part of the visible system towards the again of the mind was thinner after the food plan, suggesting that this neural change is perhaps concerned within the migraine discount.
Glutamate within the food plan doesn’t normally attain the mind; the amino acid is held at bay by the blood-brain barrier. However for some folks, this barrier can leak and let glutamate by way of, the researchers suspect. This inflow of glutamate might be activating nerve cells in a approach that results in migraines.
It’s not clear whether or not a low-glutamate food plan may assist folks with migraines who don’t have Gulf Struggle Sickness. However attempting to chop down on glutamate is perhaps value a shot, Meng says. “Right here you’re altering your food plan. So that you’re not taking a drug to deal with it,” he says. “You recognize, why not strive it? There’s no threat to it.”
VanMeter and colleagues are launching a research, in all probability in January, to look at the food plan’s results in folks with migraines however with out Gulf Struggle Sickness.
