i'm hoping some hounds may be knowledgeable on this.
i've noticed that whenever i eat spicier nacho doritos (thankfully just a once a year craving), i get a low-grade headache that begins about 2 hours later and lasts for 12-24 hours.
i checked the ingredients, and noticed that monosodiumglutamate is fairly high on the list. i'm wondering if this could be the cause, as i know that some people are sensitive to it.
msg is not something that i've had a problem with before (to my knowledge). i generally do avoid it in packaged foods, but only as a secondary factor. if choosing between two condiments, for instance, if sodium levels are on par and one has msg, i will purchase the one without. but if the one with has a lower sodium content, then i'll buy it. i also have never had any issue with any asian cuisines, which i understand in commercial preparations often feature msg. i can't believe that with the number of times i've gorged myself at asian restaurants that i've managed to avoid msg every time.
various milk products were also listed on the label, but i regularly consume cow juice in all of it's various permutations without ill effect.
maltodextrin was the only other abundant thing listed that i was unfamiliar with. i googled it along with msg, but found little info on it. it looks to be a complex sugar, but i found no side effect type data. unfortunately, as i use very few prepackaged convenience foods of this type, i've never taken the time to really familiarize myself with the various ingredients.
i even considered that it might be a tmj type effect, but i have no problems eating either of the two brands of plain tortilla chips i use regularly (santitas and snyder's reduced fat, both of which, i should add, have much shorter, less artificial, more comprehensible ingredient lists). nor do i have issues with any dense, chewy foods (think bagels) that really give the jaw a workout.
my main question is, does anyone know if msg has a critical mass? i'm ashamed to admit, but when i eat these things, it's usually during a football game, and i am prone to munching my way through most of the bag. if i control my urges and just eat the serving size, i don't notice any problem.
any info/insight would be appreciated. i will continue to work my way through the google results, but thought i'd ask here as well.
for the time being i will avoid these chips. shouldn't be too hard as i've already satisified my annual craving.
