It’s funny you mention broccoli. I generally use an anecdote to explain what you’ve just said. Primitive man wasn’t walking along in the forest one day while hunting and said, “hey that looks good”, and then take a bite. Same with cauliflower. These are man cultivated veggies that were not a part of our diet until recently. Why people don’t understand that man walked the earth for 10000 generations in good health for most of his life while eating fruits and nuts during the day (carbs and sugar for energy while hunting) and meat (protein) in the evening is far beyond my comprehension. No, they think there couldn’t have possibly been anything “good for you” until the AMA and the guvmint said so.
