That's really the thing. This processed, pre-packaged, preserved food has only been a majority in the human diet for--maybe 50 years-or-so. If your parents grew up outside of a city or its suburbs they probably ate a lot of food their family produced on its own, or bought from small local vendors.
All these food additives--we really don't know what their impact on our health will be. Some independent lab did a 6-month trail where they overfed rats with some chemicals and recorded whether the health of the rats changed, and if it didn't change an appreciable amount the chemicals were declared safe for human consumption. Unfortunately these chemicals are ubiquitous, and we have been exposed to them our entire lives... 20 or 30 years, and will continue to be... I think in a lot of cases no one really has any idea what exposure for that long will lead to.
If we're curious why cancer, diabetes, auto-immune diseases, autism, SNP diseases, allergies, asthma, epilepsy, and other chronic illnesses are rising at an alarming rate the shit in our food might be a good first place to check.
