#Welcome!

This is a sub for research & discussion about gut health.

#Avoid extremism.

Please be skeptical of all the expensive poisonous pills. There's usually no serious evidence that these result in a long-term healthier gut.

#Safer ideas.

Consider foods linked to good microbe growth (eg chick peas kill many bad microbes in your gut without harming the good ones.) There's similar studies for garlic, uncooked olive oil, & many other foods.

#Acidity

Often good microbes will produce acids that kill bad microbes but aren't harmful to you. eg lacto-microbes (found in homemade kimchi or other fermented veggies) produce lactic acid.

Acidic fruits.

If you had an overgrowth, an acidic diet could reduce microbe growth and then (after a few weeks) you could try returning to a normal diet. It's not just lemons, eg olive oil is acidic. Green apples have a ph of 3.1. Raspberries are 3.4. Cranberry juice is 2.5. Lemon juice is 2.0. Pepsi is 2.5 but that doesn't seem very healthy!

Of course there's more dangerous things like wine. And please be careful with vinegar, large amounts of vinegar have killed people.

#Rules:

No anti-vax posts.
No photos of your shit. There are lab tests for many types of harmful bacteria.
No promotion of the guru industry (even licensed MDs), eg people selling "secret" knowledge you get from joining their club that costs $$$ to join.
You may submit articles/content from your personal website but no advertising of such websites. eg don't say "Hey [user] I can help you. Simply go to my [website.]"

And similarly don't spam us with your contact info, eg "I can help you, just email me [here]"
