Europe’s fibre frenzy: excess intake can backfire
While most Europeans still miss the UK’s 30 g daily fibre target, recent trends have pushed some consumers to exceed 50–70 g per day. Such high intakes are linked to bloating, diarrhea, constipation and reduced mineral absorption, especially when fibre is increased rapidly without sufficient hydration.
High-Quality Plant-Based Diets Linked to Lower Dementia Risk
A new longitudinal analysis of 92,849 adults followed for an average of 11 years found that higher‑quality plant‑based diets are associated with a lower incidence of Alzheimer’s disease and related dementias. Participants scoring highest on an overall plant‑based pattern experienced a 12% risk reduction, while those adhering to a healthful plant‑based pattern saw a 7% drop. Conversely, a diet rich in refined grains, sugary drinks and other low‑quality plant foods raised dementia risk by 6%. Shifts away from unhealthful plant foods over a decade further lowered risk by 11%.
