If you want to learn more about health, science & medicine with a bit of dark humour thrown in then it’s a statistical probability you might enjoy this channel.

Video Description

Hydroxide is a food scientist and digital creator, with a strong following on Instagram and TikTok. She uses her deep knowledge of food and deadpan comic style to debunk viral myths, and raise awareness of food safety. In this episode Hydroxide and I examine various food trends circulating right now and uncover what’s nonsense and what’s worth caring about. Stay tuned to find out: ➡︎ Whether prebiotic sodas are worth drinking - or another marketing gimmick ➡︎ Why we shouldn’t panic about heavy metals in our food (and when we should) ➡︎ Why one cheese-related viral myth is actually making it less safe ➡ How long leftovers are actually good for - and the best way to store your food ➡︎  Kitchen tools and hacks to improve quality, taste and safety Connect with Hydroxide: Instagram: https://www.instagram.com/hydroxide.foodscience/ TikTok: https://www.tiktok.com/@hydroxide Get my free weekly newsletter filled with easy to action health tips, interesting facts and science to fill your curiosity: https://drkaran.beehiiv.com/subscribe For more useful science for your everyday life, grab my best selling book “This Book May Save Your Life”: https://geni.us/DrKaranBook An OG Podcasts production. #DrKaran #MedicalScience #HealthEducation #HealthTips Don't miss an episode!
