I have found many articles claiming that the aluminum content in soy (baby) formula is very high.What I am wondering is- does regular old soy milk for adult consumption also have very high aluminum content?I am extensively researching all possible ways to relieve my 14 month olds terrible constipation. He is not allergic to milk- he was on a milk-based formula. We VERY slowly switched over to whole cow\'s milk- which turned out to once again be terribly constipating. It was suggested I give lactose-free milk a try- which has seemed to help a little bit- it was working OK for a few days- but he did have quit the hard (and painful) bowel movement a couple days ago. We are trying other options- juices, he\'s active, we are trying to get enough fiber into this picky eater\'s diet. I am just researching the possibility of soy milk if this problem persists.I am not willing to give it to him if the aluminum content is even a small possibility. I am not finding much info about adult soy milk. Anyone??I found this on the FAQ for Eden Soy products: Claim 12: Soy foods may contain harmful levels of aluminum. (Fallon, 1996)[21] Answer 12: The author describes aluminum occurring in soy as a result of an industrial processing step. This occurs only when producers use harsh alkaline soaking solutions that leach aluminum from aluminum processing equipment. Not all soy processing uses alkaline soaking solutions and not all soy is produced using aluminum equipment. Harsh alkaline soaking solutions are used mainly in the production of modern soy foods such as soy protein isolates, soy protein concentrates, soy supplements, soy protein shakes, textured soy protein (TSP), etc. Eden does not use alkaline soaking solutions and does not use aluminum equipment. Our test results show no trace of aluminum in Edensoy, testing at a sensitivity of .1ppm. The study it references talks about soy formula, not soy milk. It sounds as if the soy picks up its aluminum content from the manufacturing equipment. Edensoy claims they are aluminum-free (implying that other companies are not)... however, it is of course a biased source! Our oldest has been on soy milk/goat milk combination for a while now (we don\'t do dairy), however, we are in process of weaning off soy for good as we have other concerns besides aluminum: MEDICAL CONDITIONS POSSIBLY ATTRIBUTABLE TO SOY CONSUMPTION Asthma Chronic Fatigue Depression Diabetes Heart Arrhythmia Heart or Liver Disease Infertility/Reproductive Problems Irritable Bowel Syndrome Learning Disabilities/ADD/ADHD Pancreatic Disorders Premature or Delayed Puberty Rheumatoid Arthritis Thyroid Conditions: Auto-Immune Thyroid Disorders (Graves’ or Hashimoto’s Disease) Goiter Hypothyroidism Hyperthyroidism Thyroid Nodules Thyroid Cancer Other thyroid disorders Uterine Cancer Weight Gain nothing is proven but the possibility is enough for us to give it up).Soy is known to have a lot of hormones in it. Not good for a growing baby. A study even showed that female infants that were fed soy formula went into puberty a lot sooner than girls that were fed breastmilk or regular formula.Other related question
