Oxidation of pectin produces a small quantity of formaldehyde as a metabolite. I’m not suggesting that you shouldn’t eat fruit or jams by the way, it’s just an example of how something considered broadly healthy still produces toxins that require elimination. Metabolism by its very nature produces energy and “exhaust” in the form of heat and metabolites. To be clear, you’re getting a lot more methanol metabolism from a drink of alcohol than an apple, so eat the fruit. No matter what we do we’re. It living forever based on diet, we should just try to avoid too much excess and accept that living isn’t a thermodynamically favorable process.
Formaldehyde is such a small molecule that you'll never avoid it. It forms pretty easily.
Molecule size isn't what determines how easily a molecule forms.
... So, "The benefits of eating fresh fruits infinitely outweighs the negatives of pectin. Even pure pectin probably is a net benefit because it slows sugar digestion and lowers cholesterol absorption vs the small amount of formaldehyde produced as a metabolic byproduct." ... would that be a more better way of describing pectin than what you said earlier?
