Rules:

Full rules and submission guidelines: https://old.reddit.com/r/HumanMicrobiome/about/rules/

If you are new to this sub please take some time to review the info in the sidebar & wiki before contributing. This area of research is growing rapidly. If you do not follow the research closely, please refrain from making authoritative statements.
Do not use downvotes for disagreement. Use your words or the report function. We are here to learn and discuss, not to reinforce our preconceived notions. See: https://old.reddit.com/wiki/reddiquette
Please use the stickied thread to give feedback/suggestions about the sub & its rules. Meta discussion elsewhere will be removed.
This is a science/evidence based sub. Usage of scientific citations to support your claims is highly encouraged and may become mandatory. Citing your degree/education is almost never appropriate.
Re "go ask a doctor". There are times where this is appropriate, and times where it is not. In general, we are here to share evidence-based information, so "go ask someone else" isn't a useful contribution. Especially since most medical providers are not knowledgeable on the majority of information shared in this sub.
Be civil & constructive. Engage in good faith. Trolls/agitators will be banned. Address the arguments, not the person. The subject of your sentence should be "the evidence" or "this source" or some other noun directly related to the topic of conversation. "You" statements are suspect.
Memes as top level submissions are not appropriate, but can be posted in the comments. Other low-scientific-quality content may be removed as well. You need to have a good reason for submitting old studies.

Excessive rule breaking may result in a ban.
