There will never be a universal answer to the question of what foods are good and what foods are bad because a universal answer would be a stateless solution to a stateful problem. And that problem is: who are you? What do you do? How much do you move your body? What are your goals? What are your genetics predisposed to? How much do you sleep? What are your causes of stress?
At one point in my life, a very well respected nutritionist recommended to me that I eat at least 3 candy bars per day. The reason: I was a D1 swimmer in college, and I couldn't keep my weight on with 4 hours of training per day, and I was having trouble keeping up with the 7000 calorie/day diet she had prescribed for me. Sugars filled that gap. And yes, that would have been unhealthy advice to almost any other American, but for me at the state I was in, it was the healthiest thing for me.
Not everybody is a swimmer. But that doesn't matter because there is no "average" human. We're all different in some way or another, and no diet is universal. Maybe we can hone in on basic dietary recommendations, but the idea that we can find universally good or universally bad things is going to be impossible.

I received equally bizarre advice from my doctor based upon some blood test results. I was explicitly directed to eat more red meat. At the time I wasn't eating much in the way of meat at all (though I wasn't a vegetarian). He recommended that as opposed to only supplementation, and preferably alongside supplementation.
