>> I'm not sure how much we can trust our own guts when it comes to seeking out nutritious foods; Right. Our appetite is adapted for pre-industrial times, when craving sweet berries while they are in season would be a good thing. We're not equipped to handle constant availability of sugared and MSG-laden processed foods that are actually designed to defeat natural satiety mechanisms. I would be cautious of demonizing fats; unprocessed fats haven't been shown to do much harm. In recent years, even Harvard Med School has backed off of low-fat recommendations, instead saying trans-fats ought to be avoided. https://www.hsph.harvard.edu/nutritionsource/what-should-you-eat/fats-and-cholesterol/ https://www.hsph.harvard.edu/nutritionsource/what-should-you... There's one way in which our appetites do point in the right direction: veggies are tastier and more appetizing when paired with butter or sauce, which also make it possible to absorb fat-soluble vitamins from the veggies.
