Artificial sweeteners explained. Are artificial sweeteners safe, do they cause weight gain, and are they actually better than sugar? Learn how sweeteners work, why they're used in low-calorie foods and drinks, and what the research says about their impact on your health. In this video, expert nutritionist Dr Richie Kirwan breaks down artificial and low-calorie sweeteners, including common ingredients such as aspartame and sucralose, and explains whether you really need to avoid them. Key Facts: Artificial and low-calorie sweeteners provide sweetness with little or no energy compared with sugar. Common sweeteners include aspartame, sucralose, saccharin and acesulfame K. Approved sweeteners are assessed by food safety authorities and have acceptable daily intake levels. Replacing sugar-sweetened foods and drinks with lower-calorie alternatives can help reduce overall calorie and sugar intake. Artificial sweeteners don't automatically cause weight gain. Your overall calorie intake remains a major factor in changes to body weight. Research into areas such as the gut microbiome continues, but this doesn't mean approved sweeteners are unsafe at typical dietary intakes. FAQ: Q: Are artificial sweeteners safe? A: Approved sweeteners have undergone safety assessments and are considered safe when consumed within established acceptable daily intake levels. Q: Are artificial sweeteners better than sugar? A: It depends on the goal. If replacing sugar with a low-calorie sweetener reduces your calorie or added-sugar intake, it can be a useful tool. Q: Do artificial sweeteners cause weight gain? A: Artificial sweeteners themselves don't automatically make you gain weight. When they replace higher-calorie sugar without those calories being replaced elsewhere, they can help reduce overall energy intake. Q: Is aspartame bad for you? A: Aspartame has been extensively studied and is approved for use within established intake limits. People with phenylketonuria (PKU), however, need to avoid or restrict phenylalanine from aspartame. Q: Should you avoid artificial sweeteners? A: Most people don't need to completely avoid approved sweeteners. Whether you choose to consume them comes down to your diet, preferences and individual needs. #myprotein #wheyprotein #protein #nutrition ********************************* Myprotein is Rated Excellent on Trustpilot 🔔 Subscribe to our channel: https://www.youtube.com/user/MyproteinUK?sub_confirmation=1 📲 Download the Myprotein app: https://myprotein.onelink.me/IYeO/o2erh9hb The UK & Europe's Number 1 Online Sports Nutrition Brand, Myprotein.
