Debunking Health Trends with Dr. Eric Topol

What do collagen powders, weighted vests, parasite cleanses, and protein bars all have in common? (According to our favorite no-nonsense doctor, probably a lot less science than TikTok would like you to believe.) This week on Laugh Lines, we’re welcoming back the wonderfully persnickety Dr. Eric Topol to help us debunk the health trends that keep popping up in our feeds (and in our shopping carts.) After our last conversation, we were flooded with listener emails, voicemails, and questions, so this time he is answering all YOUR questions! We cover big topics like brain health, Alzheimer’s prevention, and new blood tests like the “brain clock.” (We also cover cortisol panic, brain booster supplements, and over the top health challenges.) If you are overwhelmed by health advice, tired of feeling like you are doing everything wrong, or just want to laugh while learning what actually matters, this episode will leave you feeling smarter, calmer, and far less tempted to buy supplements while doomscrolling. We love to hear from you! Leave us a message at 323-364-3929 or write the show at podcast@theholdernessfamily.com . You can also watch our podcast on YouTube .
