Joe Wicks\u2019 latest television stunt, creating a deliberately dangerous protein bar<\/a> to demonstrate the \u201chorrors\u201d of ultra-processed foods, represents everything wrong with the current discourse around nutrition.\u00a0<\/p>\n By conflating all processed foods into a single category of dietary villains, he\u2019s spreading confusion and fear, rather than\u00a0helping consumers make informed choices.<\/p>\n The protein bar market, worth over \u00a33.5bn and projected to reach \u00a35.5bn by 2030, exists because it serves a genuine need. Yet if we\u2019re to believe Dr Chris van Tulleken\u2019s apocalyptic comparisons to 1950s smoking, consuming a Grenade Carb Killa bar is tantamount to lighting up a Marlboro.<\/p>\n This is not just hyperbolic, it\u2019s dangerously misleading.<\/p>\n The Nova problem<\/p>\n At the heart of this debate lies the Nova classification system, which groups foods based on processing level rather than nutritional content. Under Nova, a protein bar fortified with vitamins and containing 20g of high-quality whey protein is classified identically to a confectionery bar laden with nothing but sugar and fat. As dietician Dr Carrie Ruxton recently pointed out<\/a>, this system lumps together white bread and plant milks with infant formula and cooking sauces \u2013\u00a0hardly a useful framework for consumers trying to make healthy choices.<\/p>\n The academic community has grown increasingly critical of Nova\u2019s scientific validity. Recent research published in Appetite<\/a> found that once nutrient content and food perceptions were accounted for, the Nova classification explained less than 2% of variation in food liking and just 4% in overeating behaviour. The International Union of Food Science and Technology has established a task force<\/a> specifically to address Nova\u2019s flaws, citing its lack of quantitative criteria, oversimplification of processing, and conflicting dietary advice.<\/p>\n Even the Novo Nordisk Foundation\u2019s attempt to reform Nova<\/a>\u00a0sparked backlash, with critics worried that any revision would \u201close its teeth.\u201d But perhaps that\u2019s precisely the problem. Nova was designed to have teeth, to bite, to shock. It\u2019s a blunt instrument wielded for maximum impact rather than nuanced understanding.<\/p>\n The real world demands practical solutions<\/p>\n The \u201cjust eat more whole foods\u201d argument, while theoretically sound, ignores the realities of modern life. Research shows that most people in developed nations already meet or exceed their protein requirements<\/a> through regular eating, yet specific populations\u00a0\u2013 athletes, older adults with reduced appetites, shift workers, busy parents shuttling between activities\u00a0\u2013 face genuine challenges in meeting their nutritional needs at convenient times.<\/p>\n A teenage footballer rushing from school to training needs 20g-30g of protein and adequate carbohydrates<\/a> to support muscle synthesis and recovery, delivered in a format that fits in a sports bag. A 60-year-old with declining appetite struggling to maintain muscle mass doesn\u2019t benefit from being told protein bars are \u201cas dangerous as cigarettes\u201d. They need accessible, palatable nutrition that helps prevent sarcopenia.<\/p>\n Elite sports nutrition research has demonstrated<\/a> that well-formulated high-protein bars can improve physiological adaptation after training, with studies showing decreased exercise-induced muscle damage markers and increased antioxidant response. These are not candy bars in disguise\u00a0\u2013 they\u2019re carefully engineered nutritional tools.<\/p>\n Context matters more than classification<\/p>\n The protein bar category encompasses enormous diversity, from chocolate-coated confections with minimal protein to carefully formulated bars using whole food ingredients like oats, nuts, dates and high-quality protein isolates. National Geographic nutrition experts emphasise<\/a> that protein bars are \u201cnot inherently bad\u201d but shouldn\u2019t replace whole food protein sources entirely. Most registered dieticians recommend<\/a> using them strategically\u00a0\u2013 as post-workout recovery, emergency meal replacements when genuinely needed, or convenient snacks that contribute to overall protein goals.<\/p>\n The fundamental issue isn\u2019t whether protein bars are \u201cultra-processed\u201d. It\u2019s whether they provide nutritional value within the context of someone\u2019s overall diet. A protein bar that delivers 15g of complete protein, moderate carbohydrates, and minimal added sugar can absolutely play a positive role, particularly when the alternative is skipping meals entirely.<\/p>\n Entertainment vs education<\/p>\n Television documentaries are, fundamentally, entertainment. They require shocking content, stark narratives and clear villains to attract audiences. Dr Ruxton\u2019s observation that producers \u201cencourage presenters to make content as shocking and binary as possible\u201d explains why we get stunts like the \u2018Killer\u2019 bar rather than thoughtful examination of how different processed foods fit within healthy eating patterns.<\/p>\n The European Food Safety Authority conducts rigorous meta-analyses<\/a> showing that permitted additives are safe at specified intakes. Yet these unglamorous regulatory assessments can\u2019t compete with televisual drama of creating the \u201cUK\u2019s most dangerous health bar\u201d. The result is public panic rather than public education.<\/p>\n Fear-based messaging can backfire. When consumers are told that everyday foods are \u201ckilling them\u201d, they may experience guilt when eating protein bars that actually support their nutritional goals, or become so overwhelmed by contradictory advice that they disengage entirely from trying to eat healthily.<\/p>\n A proportionate response<\/p>\n Should protein bars form the foundation of anyone\u2019s diet? Obviously not. Should they never be consumed under any circumstances, as Wicks suggests? That\u2019s equally absurd.<\/p>\n The protein bar industry has shown remarkable responsiveness to consumer demands for cleaner labels, better ingredients, and improved nutritional profiles. Many manufacturers now offer products using grass-fed whey isolate, minimal additives, whole food sweeteners like dates and honey, and digestible fibre sources. By painting the entire category with the same brush, critics ignore this innovation and provide no incentive for continued improvement.<\/p>\n Perhaps the most telling criticism of the current panic is this: if protein bars are truly as dangerous as smoking, why do professional athletes, sports nutritionists, and elite performance coaches routinely incorporate them<\/a> into training regimens? Why do registered dieticians recommend specific brands<\/a> to clients? The answer is obvious\u00a0\u2013 because thoughtfully consumed, quality protein bars serve a legitimate nutritional purpose.<\/p>\n Joe Wicks means well and Dr van Tulleken is undoubtedly passionate about public health. But their crusade against protein bars represents a failure to distinguish between genuine dietary concerns and the realities of how people actually live and eat. It\u2019s time for a more sophisticated conversation\u00a0\u2013 one that acknowledges both the value and limitations of convenient protein sources and trusts consumers with nuanced information rather than scary headlines.<\/p>\n The grocery industry should defend products that genuinely serve consumer needs whilst continuing to innovate and improve. Because the real danger isn\u2019t protein bars\u00a0\u2013 it\u2019s oversimplified thinking that ignores the complex relationship between food, health and modern life.<\/p>\n \u00a0<\/p>\n Mike Coppen-Gardner, founder & CEO of SPQR<\/p>\n $(document).ready(function() {
