Funny you say that, the guy who started it built slot machine games. He literally took the addictive mechanics of slots and took away the money. It's why you're constantly getting rewards with bigger and better colors and effects.

No problem. There are definitely options for you. Off the top of my head, Kombucha is a big one. Fermented foods like kimchi and saurkraut. Miso is another one. Generally any good probiotic will need to be kept cold, though there are exceptions. Be wary of room temperature pill based ones, their efficacy is iffy.

Be weary of generalities online. Gut biome is an interesting area of study, but we haven't done enough studies and what you hear are mostly small studies that get played up in the media like they are hard science when really they are just to help direct and improve further studies. They were never meant to set any guidelines or direct people to action. We aren't there yet, and with how different everyone's body is with this, it'll likely be a while before anything definitive is suggested to people.

So to answer your question, we don't know. Because gut biomes vary significantly from person to person and will even change over time, and we wouldn't know what you need or don't need or if you're fine as is, it would require a lot of work to try and figure out what might help you if you're having problems. You'd need testing done of a clinical environment.

If you are having gut issues though, consuming good live culture bacteria found in things like yogurt is beneficial. Greek yogurt is the one you hear about most because it has less sugar. This is a standard reccomendation for people going on antibiotics as they don't discriminate which bacteria they kill and putting ones we know help digestion back can reduce side effects of antibiotics.

That part of NJ has changed a lot since then too. All the factories and industry that lined the Hudson are long gone. It's basically just the old Hess oil depot land that's left undeveloped, and even that got approved for a project after soil remediation is complete (which is admittedly a slow process). They fairly recently tore down an old driving range next to it too, but it's been sitting undeveloped for a while, likely due to the environmental clean up from the next lot. Aside from that it's actually really nice around there now.
