Prepackaged food manufacturers should add science-based explanations on why certain additives are in their products and how they're not harmful to human health.
Health-conscious people routinely check the ingredients on the packaging of food items they wish to buy. Seeing the E-coded additives or chemical names they refrain from buying just in case the additives are harmful.
If the manufacturer cares about the health of their buyers and the sales of their products they could:
Invest in research to find non-harmful substitutes for any additive that is potentially harmful
Explain the additives on the packaging and refer to science-based literature where people can verify the information
Market themselves as a health-conscious company that is known for the above 2 points
Reduce the additives to a bare minimum. Replace any questionable additive with a substitute that is non-harmful.
Attach a leaflet to each product. The text would be boiled down to 1-3 sentences and begins along these lines:
"You consume more of X in one <apple, chestnut, whatever-well-known-plant> than you do in this product."
