I can't remember where (maybe here) that you shouldn't use mouthwash after working out because of the effects on your oral microbiome. That fact shocked me just like this article does because it was unintuitive that your oral microbiome could have such an impact on your physiology. The effect may actually be a similar one because nitrates do sound familiar...

Alcohol or just fluoride? I have an aversion to the alcohol washes after reading years ago that the change to your mouth biome may lead to the issues that they are meant to stop.

fluoride with no kind of antibacterial is fine (careful with thymol etc). Check your toothpaste for anti bacterial as well. you want to remove food and plaque, not good bacteria.

Some time ago I read the book Complete Guide to Sports Nutrition by Anita Bean, which does also emphasize on not using antibacterial mouthwash since it removes the beneficial bacteria in the mouth which convert nitrate to nitrite. I‘m drinking beetroot juice since 3 years now and asked myself if beetroot capsules might be an alternative.

For people who don't like drinking beetroot juice, you can also regularly (French) kiss with people with healthy oral microbiomes [0][1]. Best to really get in there.

Ok but what happens when unhealthy kisses healthy? Does it balance out?

If it's not risky, I'm about to embark on a mission.

Earlier quoted context omitted.

So is the idea that widespread lead exposure led to the decline of the Roman empire largely pop science? Are you saying that's not accurate, or that the source of the lead exposure is miscounted?

Yes, that is the modern understanding. Widespread lead exposure had very little / nothing to do with the decline the Roman Empire.

Plus to prove the lead connection you have to discount the centuries of Roman dominance and growth during which lead exposure was common.

Comfortable and uninterrupted sleeping, eating mostly plants, and getting your heart rate up and muscles moving for half an hour per day. Anything else is going from 90% healthy to 99%.

I'd like to add: Stretching or some other kind of flexibility improving activities. Muscles moving for half an hour a day doesn't (necessarily) do anything for that (may even make it worse if you're doing heavy stuff). The effects on quality of life of a bit of flexibility are huge . Back pain, knee pain, shoulder pain, "RSI", and so many other ails are often just pretty much permanently cramped muscles negatively af…

Being flexible is important, but the latest research shows that heavy lifting improves flexibility about as much as a dedicated stretching program: https://pmc.ncbi.nlm.nih.gov/articles/PMC9935664/

Isn't nitrates what makes processed meats so unhealthy? Does this mean the bacon that claims to be cured with celery juice is actually on to something?

The main preservative for processed meats, and the one that reacts with other compounds to form carcinogens, is nitrites not nitrates. Nitrates are sometimes used too, especially for meats that are cured for a long time, because some bacteria will reduce them to nitrites, making them effectively work as a sustained release form of nitrite. See: https://en.wikipedia.org/wiki/Curing_salt

But the article paints this bacterial conversion of nitrates as beneficial. It’s unclear whether the conversion into nitric oxide implies the conversion into nitrites. To me it seems likely the NO benefit may come with nitrosamine production, which may raise colon cancer risk.

I think nitrosamines aren’t exclusively formed in the gut, but are present in cured meat beforehand, though. As far as I know, vitamin C prevents the nitrite to nitrosamine reaction, so fresh nitrate rich vegetable juices may not be inherently harmful through secondary nitrosamine production from converted nitrites. Additionally, their amino acid content is probably low, so as long as they are not consumed with a meal, production may be limited.

This + avoiding cigarettes, alcohol and any other drug as much as possible.

I recommend using a mouthwash based on xylitol which kills strains like streptococcus mutans but does not impair these nitrate reducers.

How would capsules affect the mouth biome, though?

Not sure, probably it doesn’t - in this regard the capsules might just be snake oil if they are not good in any other way
