I don't think genetic sequencing falls into the category of "natural selection".

It's been detected in milk, eggs, water..

I am grateful that collectively things seem to be improving. We're learning more about diseases, their causes, and their treatments.

Now consuming them may not be ideal but the fear of the unknown is overemphasized. We already know from pharmacology that higher effectiveness needs fewer data instances to prove from the strength of the effect. The more powerful something's effect not noticing it becomes increasingly improbable as patterns should become increasingly obvious in large numbers. Try not to notice plutonium toxicity.

The fact we aren't seeing more immediate effects from higher level of exposure suggests it is not catastrophic - may not be good but it is an implicit upper bound on harm based upon what we see cannot be possible. To give an absurd example we know PFAS does not cause people's heads to explode at current levels of exposure because there have been zero reports of people's heads exploding without a known cause.

There is a long list of common and unexplained medical problems like fibromyalgia awaiting an explanation like "that water you've been drinking is toxic." There is no shortage of illnesses that could potentially be caused by a problem like that.

>Rates of Parkinson’s disease are exploding

I wouldn't exactly call exploding rates of a brain destroying incurable disease a good thing.
