The Truth About Glucose Spikes, Ultra Processed Food and Microbiome Tests - Dr Nicola Guess

💬 “It's giving you very perverse and misleading and possibly even damaging advice by this glucocentric approach to nutrition.” -Dr Nicola Guess

⚡️ Dr Nicola Guess is a nutrition scientist at the University of Oxford, specialising in the dietary prevention and management of type 2 diabetes. She also debunks pseudoscience and misinformation on Instagram and Substack.

➡︎Why it’s not all-or-nothing with ultra processed foods 

➡︎The health markers you should actually be looking out for, with actionable tips
