They talk about the relationship between a cow milks protein named casein and his relationship with
AUTISM autistic behavior and the cite this 2 articles (Article 1)https://www.ncbi.nlm.nih.gov/pubmed?uid=8869369&cmd=showdetailview&indexed=google and Article 2 https://www.ncbi.nlm.nih.gov/pubmed/12168688 and they talk about those articles like they are stadistically solid. But if you go through them and analyze them
- they were only 20 patients in every group (if u want the full articles i can send them to you)
- the methodological design of those studies they dont explain if the studies are blind or double blind
- the ages of the patients (this is particularly important because the development of the brain of everyone changes with age)
the number of participant are very low to have enough statistic and interpretative power and also be able to extrapolate their results. But in the article they talk about the articles as if they are rock solid truths.
We can search for some new meta Analysis like this one https://www.ncbi.nlm.nih.gov/pubmed/28612113 and we can see the search criteria which they use they can get almos 220 patients and they identify most of the studies which show differences are related to parents tools to measure their children behavior.
And if u have a family member with autism spectrum disorder. Im sure you have heard about those diet interventions.... even some medical doctor protect those beliefs. (because there are not solid rock results)
We can talk also about Cross fit and pregnancy, insulin use and the risk of going blind (this may surprise you).
Im at your services guys and also i can get those articles for you.
