Anecdotes don't equal data. "Always" and "never" don't exist in medicine. I'm sure that your experience is accurate to yourself, but these studies have to cast a wider net since there is always variability in results.
The post you are replying to didn't say "always" it said "almost always," wich is perfectly cromulent. And it's also consistent with all the literature I have seen too.
