For today’s Dear Mark, we’ve got a three-parter. First: a question about grains and joint health from a reader who gets achy and creaky every time she veers off schedule and eats grains. Is this common? Is it supported by any real evidence? Yes and yes. Next is a short overview of cardamom, that other Indian spice that you never hear much about. Turns out it’s got some potential. And finally, I (try to) assuage the existential fears of a young guy who will eventually be an old guy freaking out about the impending and inevitable loss and dearth of his muscle mass.
