Subway is perfectly willing to admit that most of their cold cuts are turkey-based, so it seems extra unlikely that they'd go to the trouble of creating an ersatz tuna and then hiding that fact. Especially considering how cheap tuna is, comparatively. The way you cheap out on tuna salad is adding more mayo and thickeners and other fillers, not by inventing some kind of psuedofish.
Does cooked and processed food normally contain intact DNA that can be sequenced? Seems like those researchers suck at their job if they failed to figure out what the tuna is made of and still insist on drawing a conclusion based on their lack of success.
Not to mention the use of plasticizers in their bread (the same kind used in car tires.) And most importantly, factory farmed meat, contributing both to climate change and immense sentient suffering.
No, the wellness scammer who started the rumors about "yoga mat chemicals" successfully managed to pressure Subway to remove azodicarbonamide from their bread. I'm sure they replaced it with some other equally harmless dough conditioner.
I don't know much about the wellness scammer but that's a poor way to support your stance.
Azodicarbonamide has been banned in quite a few countries. It's only listed as safe at 40 parts per million. It has possible carcinogenic products in the form of other carbazides. It doesn't have a large amount of research/testing on it. It is a known lung irritant and caused respiratory issues in factory workers who produce it.
You may be okay with random hydrocarbons being added to your food. But not everyone is as naive as you.
Notice, you changed the topic to a kook and then invoked ad hominem. Very bad intentions. Much lack of substance. Dishonest attempt to convince others through baseless assertions. So shameful.
I don't know why you thought that personal attacks were merited here, but the fact remains that Subway removed azodicarbonamide from their bread years ago, as did many other fast food chains.

I wonder whether it's canned, and whether sterilizing it can make the DNA unreadable (broken down).
