An analysis by The BMJ, published on 10 September 2026, found that six of the 19 members of the UK's Scientific Advisory Committee on Nutrition (SACN) have financial conflicts of interest that the committee's own rules class as 'significant', with a further three members holding 'relevant' industry interests. SACN is the expert body that advises the UK government on nutrition policy, including guidance on artificial sweeteners, ultra-processed foods, vitamin D supplements requirements, and dietary advice for babies, young children and people over 65; its reports feed into national policy and NHS healthy eating advice. The BMJ analysed SACN's latest register of interests, published in June 2026, and found links to companies including Coca-Cola, Nestle, Danone, Mondelez (Cadbury's parent company), Sainsbury's and Pepsico. One adviser was until recently a senior figure at the British Nutrition Foundation, a charity funded by several of the same companies. The finding follows a 2024 BMJ investigation that found more than half of SACN's then members had industry ties.
Why this matters for nutrition guidance
Chris van Tulleken, an infectious disease professor at UCL who has written on food industry influence, told The BMJ that 'SACN's authority depends on its independence, and these interests weaken public confidence.' Rob Percival of the Soil Association went further, saying conflicted members 'need to leave the committee immediately.' The Department of Health and Social Care said current advisers cannot take on new conflicting interests, that members with significant conflicts are excluded from related discussions in the meantime, and that all members are expected to meet an updated interests policy within two years. SACN's remit covers advice used UK-wide, including the 2016 report that underpins current UKHSA guidance on vitamin D in autumn and winter.
What this means for your supplement routine
SACN's advice, including its long-standing guidance on vitamin D intake in autumn and winter, is not overturned by this finding, and readers should keep following official public health advice from bodies such as UKHSA rather than treat this story as a reason to stop. What it does highlight is that some of the guidance shaping vitamin and mineral recommendations comes from a committee with acknowledged industry links, which is worth knowing when weighing that guidance against marketing claims from any brand, including ours. Members researching vitamins and minerals independently can compare prices across brands in the vitamins and minerals collection.
