What does the body of evidence say on acne and how to treat it? Plus: you’re going to want to pay attention to this latest study if you have food allergies, and Chris answers listeners’ questions about when to exercise, whether spinal cord stimulators work, and why some older adults are told that surgery would mess with their brain.

A Block: Acne

(0:59) Who gets acne; what causes acne; what are the risk factors for acne; how to treat both mild and moderate-to-severe acne.

B Block: New Food Allergy Drug

(34:16) A drug already approved to treat asthma, omalizumab (Xolair), can work against food allergies, including peanut allergy.

C Block: Answering Emails

(47:32) Questions about when is the best time to exercise (and whether or not you should be fasting); the benefits of spinal cord stimulators for people dealing with chronic pain; and why some older adults are being denied surgery.
