Article obviously not written by a Californian!!! LOL Of course, we grow all the good stuff which goes out to the tables of America and the world, provided it is bought and eaten (although nothing beats the flavor of back yard tomatoes!). https://www.youtube.com/watch?v=g0C4FOL1qIw
We Californians do eat well and healthily. However, the article does make a good point about the ability of the food chemists to simulate natural flavors and "paint" them on otherwise not particularly-to-non-nutritious substrate.
Other social movements have also played into this situation, chiefly the feminist movement of the past sixty years which has systematically denigrated the idea that women should learn to cook and run a household, such that there are now a couple generations of women who are incompetent in the kitchen and ignorant of nutritious foods, and who often have also failed at marriage so they are having to work and raise the children and claim no time to do other than eat non-nutritious fast foods, because they lack the skill to fix quickly nutritious meals. No wonder the country is obese! Just think of all the women one knows who brag they can't cook and eat all their meals out.
