Are those relevant to addressing America's national diet deficiencies? None of them are currently anywhere big enough to make a practical difference to most people.
Also most of the health problems with what people eat are from what foods they eat and how much they eat rather than from not choosing the highest quality of those particular foods. E.g., someone might snack often on candy. If they can be convinced to switch to snacking on fruit it doesn't really matter much if they get that fruit from Safeway or a farmer's market. Maybe the farmer's market fruit is healthier for them than the Safeway fruit but the difference will be tiny compared to the gains from switching from candy to fruit.
