Each generation since the 1960's has been ingesting more and more natural flavors with Generation Alpha now ingesting particularly high levels

In the 60's basically only sodas had natural flavors. Now almost every food item including snacks for children, supplements particularly sports supplements, almost every sort of drink on Earth, almost everything vaped, almost every THC/CBD concoction, almost all condiments, almost every alcoholic drink have natural flavors.

Natural flavors are plant extracts.  See this page.  

Plant extracts contain polyphenols that are strong antioxidants. Dietary antioxidant can have very unfavorable effects. See this entry in this book.  

Each generation since the 1960s has been ingesting more and more natural flavors with Generation Alpha particularly hard hit. Generation Alpha consists of individuals born entirely in the 21st century.

To address behavioral difficulties of Generation Alpha diets of Generation Alpha have to be altered where natural flavors have to be eliminated from diets. A World without natural flavors would be a much less depressed World.
