Is this going to be like the micro-plastics-are-actually-contamination-from-lab-gloves news all over again?
I'm all for removing PFAS and similar chemicals from the many places and uses they aren't needed, but if people don't care about PFAS in their tap water, they certainly aren't going to care about penguin PFAS.
1. Why you/penguins should care about this: PFAS suppress immune function and reduce reproductive success in birds [1]. They transfer from mothers to eggs and disrupt thyroid hormones and immune organ development in avian embryos [2]. In humans, IARC classified PFOA as a Group 1 carcinogen in 2023, which means there is the highest classification (i.e. International Agency for Research on Cancer is convinced PFAS causes cancer). A 2x increase in serum PFAS is associated with a 49% drop in vaccine antibody levels in children [3]. These are the same compounds showing up in >90% of penguin samples in remote Patagonia. They don't break down. They bioaccumulate up the food chain. And the "safer replacements" like GenX are clearly reaching the ends of the earth too. This is bad for penguins and for people.
2. This is a problem I'm taking seriously. My startup, NeutraOat (neutraoat.com) is developing a modified oat fiber that selectively binds PFAS and plasticizers in the GI tract without stripping nutrients like charcoal does. It will also remove PFAS from the blood. Early-stage, binding data is promising. Clinical trial happening in ~6-9 months. Website has our early data and a pre-order signup form.
My hypothesis is that PFAS and microplastics are responsible for the drop in female fertility, drop in male fertility, drop in testosterone levels, increase in obesity, etc. These chemicals are pervasive in the environment, causing disruptions to the endocrine system that regulates our body. This is why higher elevation areas seem to lag the trends, as they are not getting as much down stream accumulation in the environment. My sister hypothesis GLP-1s are a chemical that is undoing some of that disruption. If what you are doing works, it'll imo be a modern day Norman Borlaug.
I've signed up and look forward to following your success.
Your mission is near and dear to my heart- I grew up on an US Air Force base that is a PFAS superfund site and didn't find out about it until much later in life. Recently I've jumped into research linking PFAS contamination in dog food to canine Addison's disease.
We've been pretty cavalier with PFAS and it's horrifying.
Looking at the studies on the site I’m only seeing comparisons vs placebo and activated charcoal - why not compare to non modified regular beta glucan that is in most oats?
Is any science ever "settled"? Regardless, it's a wikipedia page, so of course it's simplified. There are countless citations on the page referring to various published papers, so.. /shrug

Seriously though, amazing idea I love this.
