Health and Fitness Q&A with Kevin
Whenever I have a question about health matters that is too complex for an MD or academic researcher to get right, I ask Kevin. Nobody I know has a better combination of broad-based current knowledge of the primary literature, plus a whole-system view and understanding of compex dynamics, plus the practical will and experience in living by (and updating) his conclusions.
Here are some questions I had for Kevin recently and his answers.
Rafe: Do the BPA results (such as they are) cause you concern? Do you still use your Nalgene bottle? Would you let your infant or child drink from a plastic bottle or sippy-cup?
Kevin: I am somewhat but not overly concerned about BPA. We have eliminated BPA-containing beverage containers from _daily_ use. However, I have not swapped out the emergency Nalgene bottles. I would let my infant or child drink from a BPA cup if we were over at a friend’s house (i.e., I wouldn’t grill the friend on their BPA posture), but I would throw away my own BPA containing cups.
Rafe: I just learned that Celebrex is supposed to have all the anti-inflammatory power and none of the gastrointestinal issues. True?
Kevin: All of the Cox-2 inhibitors make the claim about no gastrointestinal issues. When I looked at the data a couple of years ago, the difference in incidence was actually not that great in the general population. Moreover, the Cox-2’s have a higher incidence of cardiac side effects (while Cox-1’s are actually cardioprotective on average). Avoid the Cox-2’s unless you have known high gastrointestinal sensitivity to the Cox-1’s (or you have a history or unusual risk of gastric ulcers, of course). If you’re worried about taking high dose, post injury Cox-1’s, take bismuth subsalicylate (e.g., Pepto Bismol, but I prefer the generic chewables) at the same time. It has a prophylactic effect.
Rafe: When working out, do you increase your protein intake, either generally, or in relation to your workouts? If so, does it matter what form the protein takes?
Kevin: In general, I recommend getting 20% of your calories from protein, period, full stop. When you work out, your caloric intake goes up and takes care of additional protein requirements. It’s best to get protein from your regular diet, but if you need to supplement, here’s my view. Egg protein can increase the sulfurousness of your gas passing, but I seemed to tolerate it well back when I had to supplement (because my caloric requirements were so high). Soy is cardioprotective (though mildly estrogenic). So most people should go with soy.
