Typically, no. The environment in the stomach is far too hostile to yeast to allow for the time required to ferment.

That said, there is a condition known as Auto-brewery syndrome where the stomach does not kill off the yeast fast enough and they _do_ ferment some of the sugars, producing alcohol.

Generally no, baking kills yeast. What’s in there when we eat it is almost certainly dead.

Even if it weren’t, there’s no way for the yeast to get into our blood, the worst they can do is eat the sugars in your stomach. Which they can totally do…don’t eat a lot of live yeast, for this reason.

I feel like the harsh acids in your stomach would disrupt the fermentation process. Plus fermentation takes time and it’s not the same as distillation, but anyway it doesn’t happen overnight it takes some time.

As both a hobbyist baker and brewer, I can confirm that in (carelessly excessive) large quantities, active yeast can produce alarming amounts of gas and small quantities of alcohol in your system.

Don’t eat uncooked yeasted dough or drink actively fermenting beer and you shouldn’t ever run into that problem.

The yeast is killed by cooking. In the case of fermented beverages most of the yeast settles out before you drink it and you do not drink much yeast. Your stomach acid kills what you do drink.

If you straight up drank active yeast slurry and sugar water it probably could overwhelm your stomach acid and ferment in your stomach and intestines, producing a lot of gas (co2) and some alcohol, but probably not enough alcohol for you to notice any effects in the time it would be in your stomach/intestines. It would likely be very uncomfortable.
