I have been saying this for ten years now (NYT link) →[More:]
About ten years or so ago, I worked at a biotech with some pretty high end dieticians. Concerned with my diet at the time, I asked one (a Ph.D.) what her recommendations were for a truly healthy diet, as opposed to the media-driven 'fad-of-the-week' mentality.
Her response? Pretty much what's in that NYT article there. To paraphrase her 3 Big Tips:
1) - throw out any processed / packaged food (meaning all cans, boxes or bags) that's in your fridge or cupboard now.
2) - at the grocery store, shop the perimeter, don't go down the aisles
3) - if you eat meat, do so more as garnish than main course.
Turns out that's pretty much the gist of this whole long, long essay.
Over the course of ten years, by doing this, (well and turning off my TV and parking my car, too), I've lost nearly forty pounds and at 38 years old, was recently mistaken for a teenager.
