Thoughts on "loud voice" - took away breads with 282 preservative and huge difference in volume and improvement in speech for my son. Also we avoid 160b, colours and additives generally....he has no idea he is talking loudly. – Jennifer from facebook group

My encopresis/megacolon/chronic constipation/overactive bladder 5 1/2 year old always talks super loud too, more and more great reasons to celebrate that we are finally trying a supervised elimination diet!! – Michelle from facebook group

Oh yes, when my son has had the "bad additives", LOUD voice is definitely one of this symptoms. Along with whiny higher pitched voice. That is a sure indicator to us that he has ingested something he should not have. – Sally from facebook group

I have a hearing impaired son, had hearing aids for several years. He has the loud voice thing. Thought it was all part of his disability, until failsafe! He now speaks normally, and the first sign of a reaction is the voice! He also is on soy, the only thing that I can't change, as he seems not to tolerate any other milk substitute... tried every one, and gets awful diarrhoea and leaking .. not fun when you are 8 and at school! I think the loud voice is very related, and I DO have a hearing impaired child ... also i am frustrated as all my soy kids have been long term bedwetters! and the non soy kids not so... we are currently RPAH elimination diet, and the compulsive speech also disappeared in this child, he hardly talks and is calm and listens better, and the youngest who is 2 has had a really odd reaction to removing all the additives...we were able to understand him finally!- (he was previously diagnosed with a speech delay) yet when he accidently had a flavoured drink from a guest... his speech reverted to gibberish again. It happened after a banana, given by a babysitter, and again when an additive was shared by a relative! three times in three weeks, we 'lost' his speech for about 5 hours.... ! (and got all the other behaviours).. so there is definitely issues with the speech centre of the brain, not just hearing issues why they speak louder... at least in my family! – Ries from facebook group

Sals and amines do it for us, as well as the additives. When we are very strict with only a few foods his voice is normal. – Susan from facebook group

My son has always had a very noticeably loud voice which has annoyed many of his teachers and i have had his hearing tested and had him tested for auditory processing all of which he has passed. Its not until we went failsafe that we noticed his voice is now always normal, the big improvement came from removing all artificial colours, preservatives and flavours but now if he has too many sals he gets quite loud again and then we know to cut him back, his concentration and energy levels seem to go hand in hand with it too.- Lee from facebook group

That is our son to a tee. If we stay low everything his voice is pretty normal. If we let a bit of mod sals creep in the voice is one of the first things we notice. If he has more then we notice the reaction and silly behavior as well as testy/ over emotional. Also energy and concentration.- Susan from facebook group
