I don’t know enough to comment on the Hygiene / Old Friends hypothesis, but anecdotally it seems like almost everyone I know now has an allergy or autoimmune disorder of some sort. After giving birth, my sister suddenly developed something similar to celiac disease (but not quite the same; I don’t think doctors ever figured out exactly what it is) to where she can’t eat grains and a few other types of food as well. I…

Exactly, anecdotes, with a healthy portion of the Availability and Confirmation Heuristics. We already know that women are more susceptible to auto-immune responses and that pregnancy is one of the reasons for that disparity between the sexes (carrying a foreign invader for 9 months plays with the expression of immunity genes in a manner that occasionally - rarely, at a population level - backfires.) And we know that…

When I was getting my immunology PhD, the prevailing thought about the prevalence of autoimmune disease in women was that estrogen promoted B cell survival, leading to more anti-self B cells from being removed.

Once a (DNA) virus incorporates itself inside your DNA and that cell divides you are never getting rid of the virus

Wait, is that how viruses work? Is a parent guaranteed to pass on viral illness to their children (genetically) then?

The cells infected by these viruses don't form the sperm and eggs, so no. But a great portion of our genomes is thought to come from old viruses (which actually may be used immunologically!)

Only some viruses work this way, HIV is an example. This is a good article on endogenous retroviruses [1], that is viruses that work by integrating themselves into host DNA (a retrovirus) and made it into germline cells (eggs and sperm, the endogenous part).

And to clarify for those reading this, HIV is not passed from mom to baby via inhereted genome, but as a blood borne illness in pregnancy, during birth, or in breastmilk.

I use to get the flu 1 or 2 times a year. I started going out in more crowded areas, going to pub, etc, and I haven't had a cold or flu in 4 years. I don't know the article knows as much as they think they do about health, because using muscles also damages them. I been nursing a bicep injury for the last 4 months. I get its not a prefect analogy, but nothing is, else it would be the same thing I don't think people s…

> Addictive amounts of sugar in a lot of food. Realistically, this and seed oils are the only place you are going to really encounter GMOs. If you are avoiding such processed food anyway... > GMOs everywhere unless you can pay extra for organic. If you really must binge on the junk food and are concerned about any GMO content, why are you paying extra for organic? Why not just buy non-GMO products?

> If you really must binge on the junk food This is inaccurate - the other day I wanted to get some cookies for a child - label said sugar content was like 25%, that's insane. I have baked cookies myself, you don't need that much sugar to get decent tasting cookies, they are not suppose to be junk food. it's everywhere, not just chocolates, even in bread. It better be a malevolent conspiracy, because if not, then it'…

Sugar is not only addictive and harmful, it's also a preservative. It's cheap to add and provides longer shelf life.

This is an excellent article. Too many people believe that kids getting colds will help their immune system get stronger. In reality, getting sick is almost never beneficial. The information about the hygiene hypothesis and how it is really more about "old friends" is also very important and not widely understood. Many don't know about the hygiene hypothesis at all and those who do usually interpret it incorrectly.

Kids getting colds allows them to develop immunity to some of the hundreds of endemic upper respiratory viruses that constantly circulate throughout the human population. They're going to get infected with many of them sooner or later, so better to get it over with sooner. This protects them later in life when their immune systems are less effective.

You say the article isn't fully truthful. Where are your sources to back up your claims? What are your credentials? Or are you just pulling it out of thin air?

Have you tried taking an anti-acid or acids reducer? I was getting a rough depression after eating certain foods. My/my doctors current hypothesis is my liver was producing too much bile acid and triggering a condition known as bile acid malabsorption. This would basically wipe my gut out. I couldn’t absorb nutrients correctly so my mood and energy levels would drop. I now know it lasts a few days if I goof up my die…

antacids just made my body ramp up making more bile. I eventually started taking betaine HCL, which helps when I have reflux or pain in the stomach. Seemingly a lot of bugs survive the stomach acid these days. Started taking the betaine when I went on carnivore diet and saw undigested meat in the stools.

Aw man, that’s a pain.

When people walk into a restaurant - fast food, slow food - especially before COVID, do you see people go to the bathroom to wash their hands before the meal? That never happens.

I've never seen it happen either - and I live in Poland, though I haven't seen it in my various visits to China, Germany and the UK either. Who actually does go into the restaurant bathroom specifically to wash their hands before the meal?

Spanish here. I do it all the time. I even carry a small bottle of alcohol in case I go to a place where I can't wash my hands first.

I would say most people do wash their hands here, however I have seen everything. From people not washing them to people using the toilet, not washing them, and then sitting on the table for lunch.

I'm Polish and I do - so do some of my friends. Typically right after ordering, before even the beverages have a chance to arrive.

My father would wash hands after petting a dog even, so I guess it's his germophobia that set the standard in my household.
