Recently went through first aid training and the instructor claimed putting honey on wounds would help them heal faster. (Sample size 1) I tried it on myself and a wound that was stubborn about healing was better very quickly.

Same principle, reducing water activity (aw), is how Nutella keeps fresh for so long without refrigeration: its water activity is even lower than honey. Most bacteria need an aw of around 0.85 to thrive, Nutella’s aw is around 0.4, honey’s around 0.5-0.6. Peanut butter is 0.7, so it stays fresh for relatively long, too. Here’s the definition of water activity from FDA: https://www.fda.gov/inspections-compliance-enfor…

In the end drying grass to create hay is also the same principle: dry enough (say < 15% water) and it doesn't do much at all, being pretty dead. Higher and you get all kinds of life having its go at it.

Yep, and you end up with silage if it's stored anaerobically.

I'm not sure that number is meaningful without knowing how many parents are giving their infants honey. Granted I'm in a high-income, high-education area, but at least in my bubble, "don't give babies honey" seems to be common knowledge, so it's possible there are relatively few instances and a high percentage result in complications.

Whole food crunchy Instagram grifters push that infants should eat honey Though tbh do people really eat that much honey? I only have some in my kitchen to have with tea when I have a cold. Other then that I almost never use it.

No honey with greek yoghurt?

This is something that I think about sometimes. Life on Earth has had billions of years and expanded to fill so many niches, but they're nearly all damp niches. Nothing has ever really managed to really thrive in deserts. Sure, there are a few cacti, succulents, a bit of scrub, a few palms and rodents and a few birds that eke out an existence. But really it's mostly barren, compared to temperate or tropical climates…

Even then, you don't have to spend much time in a desert to realise that what does grow is in low lying places where there's water underground, or where brief rains collect.

By definition, the desert "niche" IS filled. It has as much life as it can support. That doesn't mean wall-to-wall forest; you wouldn't expect to find that covering a field of barely weathered granite, either.

All life on Earth uses water to transport chemicals and ions across its cells. Period. It's one immutable requirement of life on Earth.

I wonder if there's some general mathematical description one could form of the biomass per acre versus water content of the "surface soil". The oceans provide the extreme, but even then there are "biodeserts" far from land where there are insufficient nutrients (organic chemicals, probably) to keep even algae going.

My honey jars basically turn into forensic time capsules of breakfast past, and still nothing grows

But the same holds for my sugar jar.

Are you all barbarians?

Nothing but clean spoons go in my sugar jar, and I rarely dip out honey with anything but its own dipper - which never touches food.

Reginald, bring me my fainting couch, stat!

Feeding honey to newborn babies is a common practice in India. Sometimes it's their first ever food.

We waited until our kid was four, just to be safe, but it's was also honey from our own bees, so I somehow felt it less safe. Kid went full Winnie-the-Pooh on the jar.

"OK, sister bees, now remember: this season we'll be feeding the hu-man's child, so wipe your feet before entering the hive, and if you feel the sniffles coming on, Don't Make Honey!"

This article is missing what I think is a pretty important PSA on the topic of bacteria in honey: Honey commonly contains small amounts of the anaerobic bacteria Clostridium botulinum, which causes botulism. This is why you should not feed honey to infants, because their immune systems cannot safely handle any amount of it yet. Even though the levels apparently are small enough for the rest of humans to consume worry…

Honey contains spores of Clostridium botulinum, not live bacteria. And as such, honey cannot in itself cause botulism. But the intestinal microbiot of infants (not their immune system) is not necessarily developed enough, and as such Clostridium botulinum can colonize their intestine (it strives in anaerobic environment) and then they can develop a special kind of botulism where the toxin is actually produced in thei…

You state honey cannot cause botulism, and in the very next sentence explain how it can.

I think you're making a novel semantic difference, which is irrelevant to anyone puking their guts out from botulism.

I had a planter wart surgically removed which they packed with Manuka honey and because it's a deep open wound it needs to heal from the inside. I changed the dressing and repacked it every few days for weeks and the wound was absolutely pristine ever time. I live in the tropics where people die because due to infection which makes it even more interesting that they use honey.

plantar wart. all wart removals should heal pristinely, warts are on only the outermost layers of skin above where scarring occurs.

Pristine implies not only a lack of scarring, but no infection during the healing process.
