NHS staff are fighting an uphill battle against a tidal wave of misinformation about food supplements, which is creeping into consultations and putting patients' health at risk. A recent YouGov poll has revealed that nearly half (40%) of frontline healthcare workers encounter patients bringing in dubious claims about supplements at least once a week.
Those on the frontlines – particularly nurses and midwives – are bearing the brunt, with 53% reporting weekly encounters with such misinformation. This trend is siphoning off precious time during NHS consultations, diverting attention away from evidence-based discussions. The World Cancer Research Fund (WCRF) has expressed alarm that patients' faith in unproven dietary regimes and supplements could increase their susceptibility to serious conditions, including cancer.
GPs like Dr Philippa Kaye are seeing the consequences of health misinformation firsthand. She says patients often arrive with screenshots from social media, printouts from wellness websites, or videos from platforms like TikTok. Dr Kaye notes a worrying misconception that products labelled 'natural' or endorsed online are automatically safe, while prescribed medicines are viewed with suspicion – a fundamentally untrue claim.
She cites examples of hidden risks associated with certain supplements: liver injury linked to turmeric supplements, St John's wort interacting dangerously with other medications, and the misuse of magnesium types that can cause adverse effects like diarrhoea. Dr Kaye stresses that if a supplement has an active ingredient capable of producing an effect, it also carries potential problems. The WCRF’s UK director, Steven Greenberg, echoes these concerns, highlighting dubious claims about "horse wormers to apricot kernels, which can cause serious cyanide toxicity," and lamenting the 'false promises and dangerous claims' flooding social media.
A recent survey of 795 NHS staff was conducted ahead of Cancer Prevention Action Week, which starts on Monday. In response to the growing public misunderstanding about health, cancer specialists plan to dedicate their activities for the next three years to highlighting the risks posed by misinformation – a long-term focus that underscores the gravity of the situation and the perceived need for sustained public education.
Sharon Moffat, a breast cancer patient turned campaigner, shared her personal experience of being bombarded with unverified advice after her diagnosis. While many suggestions came from friends and family, she often found herself questioning the evidence behind them – a process that left her feeling overwhelmed and uncertain about what to believe.
The NHS is grappling with a public health issue that requires immediate attention, said experts. As the WCRF's Steven Greenberg noted, 'We need to educate the public on the risks of misinformation and help them navigate the overwhelming amount of information available.' Dr Kaye agrees: 'We must be more proactive in addressing this issue – our patients deserve nothing but accurate, evidence-based advice.'
