It seems pretty clear that all the so-called food science behind the ridiculous dietary rules taught in schools at government and foodnazi insistence was bullshit and mostly made up and faked. There was zero truth to any of it and yet it still resonates today and probably will for another 50 years. Of course, by then it will be padded with more "expert" guidance telling you not to eat tasty stuff but stick to lionfish, weeds and rocks. "If it's good enough for mother nature and birds, then it's good enough for you!"
However, although the Guidelines are required and purported to be “based on the preponderance of current scientific and medical knowledge”, they did not include some of the recommendations of the Scientific Advisory Committee and therefore do not describe an optimal dietary pattern. For example, the World Health Organization recently classified processed meat as a carcinogen and red meat as a probable carcinogen, based on evidence that has been in existence for some time. Yet the Dietary Guidelines make no mention of this and state that processed meat can be accommodated in a diet if the diet is within limits for other nutrients.I think the "expert's" fascination with what other people eat ought to end at the end of their own table. All I can say is, if you don't like what I eat, what gives you the right to tell me no or double-tax it? This strange government food fetish must end. Stop electing nannies.
On the gripping hand, at some point the clowns in government are going to wake up and realize that if they ever did offer excellent and beneficial dietary advice to the populace, people would live longer and consume a much larger share of socialized medicine $ than they currently do. At the moment, I think seniors consume ~80% of medicare spending. If fewer people lived longer....... well. I'll leave that to the food nazis. I'm sure they're rubbing their heads and trying to figure out how to get people to eat rocks coated with sugar.
