8 topics — all backed by peer-reviewed, independently funded research
Ultra-processed foods and cardiovascular disease risk
Large-scale cohort studies consistently show that high consumption of ultra-processed foods is associated with significantly elevated risk of cardiovascular disease, even after adjusting for overall calorie intake and nutritional profile.
Red and processed meat consumption and colorectal cancer
Multiple large cohort studies and meta-analyses have established a clear dose-response relationship between processed meat intake and colorectal cancer risk. The IARC classifies processed meat as a Group 1 carcinogen based on this body of evidence.
Sugar-sweetened beverages and type 2 diabetes
Evidence from multiple independent prospective studies confirms that regular consumption of sugar-sweetened beverages is a significant independent risk factor for developing type 2 diabetes, beyond the effect of excess calorie intake alone.
Omega-3 fatty acid supplements and cardiovascular outcomes
Recent large randomised controlled trials have produced mixed results on omega-3 supplementation for cardiovascular disease prevention, revising earlier optimistic findings. The picture is more nuanced than widespread supplement marketing suggests.
Dietary fibre intake and all-cause mortality
A comprehensive systematic review and meta-analysis commissioned by the WHO analysed 185 prospective studies and 58 clinical trials, finding strong evidence that higher dietary fibre intake is associated with reduced risk of multiple chronic diseases and all-cause mortality.
Artificial sweeteners and metabolic health
Emerging research challenges the long-held assumption that artificial sweeteners are metabolically neutral. Recent large prospective cohort studies suggest potential associations with metabolic syndrome, though causality is not yet established.
Full-fat dairy and cardiovascular disease
Contrary to decades of public health messaging, recent large cohort studies have found no significant association between full-fat dairy consumption and increased cardiovascular disease risk, and some suggest a modestly protective effect for certain dairy types.
Fruit and vegetable intake and stroke risk
A large meta-analysis confirms a dose-response relationship between fruit and vegetable intake and stroke risk reduction, with each additional 200g daily portion of fruit or vegetables associated with measurably lower stroke risk.
