I see what Eleanor Barkhorn means. The author of the piece, Jennifer Berman, says she’s been a health-food nut from way back:

And now, in the Whole Foods era, as I push my shopping cart down spacious aisles stocked with nonprocessed, gluten-free, non-G.M.O., heirloom, grass-fed, free-range and artisanal goods, I am pleased to know that I was ahead of my time.

Imagine my shock, then, at my last physical, when my doctor told me I had hypothyroidism, common in women over 40. When I got home I looked up the condition on the Internet and found a list of foods to avoid. Kale, which I juiced every morning, tops the list, followed by broccoli, cauliflower, cabbage, Brussels sprouts and collard greens — the cruciferous vegetables I consumed in large quantities because they are thought to prevent cancer, which runs in my family. And flax — as in the seeds — high in omega 3’s, that I sprinkled on cereal and blended in strawberry almond milk smoothies. Also forbidden: almonds and strawberries, not to mention soy, peaches, peanuts, corn, radishes, rutabaga and spinach.

And then she went to the dentist, and got another shock. Read the whole thing. 

Give it up, people. You can’t win. Might as well go eat a cronut.
