https://www.dralexnewsletter.com Join the community by signing up to my daily newsletter! Practical health advice, straight to your inbox, every morning. Artificial sweeteners are found in thousands of everyday foods and drinks, from diet fizzy drinks and protein bars to yoghurts, sauces and chewing gum. They promise all the sweetness with almost none of the sugar, but are they actually healthy? Or have we simply swapped one problem for another? In this video, I break down the latest evidence on artificial sweeteners, including what they do inside your body, how they affect your gut microbiome, blood sugar, insulin, appetite, cravings, heart health and cancer risk. We'll also look at whether artificial sweeteners really help with weight loss, why the World Health Organization has changed its advice, and which sweeteners I personally think are the best (and which I'd avoid). If you're trying to lose weight, reverse insulin resistance, improve metabolic health or simply make healthier food choices, this is a balanced, evidence-based guide to what the research actually shows. In this video you'll learn: -Whether artificial sweeteners are actually healthier than sugar -What happens inside your brain and gut when you consume sweeteners -How sweeteners may affect your gut microbiome -Whether sweeteners increase insulin or blood sugar -The truth about artificial sweeteners and weight loss -The evidence linking sweeteners to heart disease and stroke -Whether aspartame causes cancer -Which sweeteners have the strongest evidence for safety -Why reducing your overall preference for sweet foods may be the healthiest long-term strategy TIMESTAMPS 00:00 – Introduction 01:47 – What Artificial Sweeteners Actually Are 03:27 – How Your Body Reads Sweetness 05:24 – The Gut Microbiome & Blood Sugar 07:29 – The Heart & Circulation 08:21 – The Cancer Question 09:40 – Appetite, Cravings & The Sweet Tooth 12:17 – The Real Benefits 14:13 – Going Through Each Sweetener 17:13 – Why Coming Off Sweet Things Is Better REFERENCES Artificial sweeteners induce glucose intolerance by altering the gut microbiota https://pubmed.ncbi.nlm.nih.gov/25231862/ Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance https://pubmed.ncbi.nlm.nih.gov/35987213/ Artificial sweeteners and risk of cardiovascular diseases: results from the prospective NutriNet-Santé cohort https://pubmed.ncbi.nlm.nih.gov/36638072/ The artificial sweetener erythritol and cardiovascular event risk https://pubmed.ncbi.nlm.nih.gov/36849732/ Xylitol is prothrombotic and associated with cardiovascular risk https://pubmed.ncbi.nlm.nih.gov/38842092/ Carcinogenicity of aspartame, methyleugenol, and isoeugenol https://pubmed.ncbi.nlm.nih.gov/37454664/ Use of non-sugar sweeteners: WHO guideline https://pubmed.ncbi.nlm.nih.gov/37256996/ Association between intake of non-sugar sweeteners and health outcomes: systematic review and meta-analyses of randomised and non-randomised controlled trials and observational studies https://pubmed.ncbi.nlm.nih.gov/30602577/ Artificial Sweeteners and Risk of Type 2 Diabetes in the Prospective NutriNet-Santé Cohort https://pubmed.ncbi.nlm.nih.gov/37490630/ Artificial sweeteners and cancer risk: results from the NutriNet-Santé population-based cohort study https://pubmed.ncbi.nlm.nih.gov/35324894/ Ultra-processed food exposure and adverse health outcomes: umbrella review of epidemiological meta-analyses https://pubmed.ncbi.nlm.nih.gov/38418082/ #artificialsweeteners #sweeteners #nutrition #diet #weightloss #guthealth #insulinresistance #metabolichealth #longevity #health #dralex #doctoralex
