alt Hacker NewsTwo notes for cynical HN crowd:
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.

Wow a non-AI startup doing good for the world (no gambling) in 2026? Ycombinator, someone get OP some money!
Seriously though, amazing idea I love this.
Interesting, best of luck with this, microplastics really are the modern lead.
You said it removes them from the blood: does the body dump microplastics in the gut for your product to remove them from the blood or how does it work (if you can answer due to proprietary reasons)?
Are saunas and blood donations not also effective for this?
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.
That’s a great idea. Have you compared the effects of your product with non-modified soluble fibers? Afaik, soluble fibers not only from oats but also from vegetables and beans already have solid effects on toxin-binding in their natural state.
