Sure, some food may have contaminants. Fish is a good example. You might have to choose, for instance, farmed salmon instead of wild. Pesticides may be a factor. Microplastics are going to make this a more annoying problem.

But far more important is to control _what_ you eat. A tomato is a tomato. But ketchup is not a tomato. You may get health issues from contaminants, maybe. But you _will_ have health issues due to bad diet.

Absolutely. I was more thinking about "was this tomato grown with pesticides? If so, which ones? What health impacts does it have?"

And if you think pesticides is a small issue, "was this chicken/cow/turkey/... loaded with antibiotics?"

Of course, as I said, eating less processed food is a very simple yet effective choice, but beyond that, it sadly seems to get very murky very fast.
