I agree it's confusing. If longevity is a goal then moderation and balance in all things is key. I think there's also decent evidence for keeping your body on the "lean" side of "healthy weight" per the age-adjusted BMI charts through moderate caloric restriction. The evidence is growing for the near-term health benefits of minimizing consumption of processed foods. Primarily all the stuff in bags and boxes that can sit on store shelves for weeks and months and not spoil. I've also learned to not place much value on "organic" labels. It's expensive and hard to do correctly and not universally better even when it is done correctly. The external verification requirements are almost entirely based on remotely filed "self-reports" with inspections.
