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.

Chardonnay By-Product May Improve Cardiovascular Health
Scientists from UC Davis, Sonomaceuticals and the USDA found that a high‑dose Chardonnay grape marc blend lowered post‑prandial triglyceride spikes in adults with mild dyslipidemia. In a 16‑week double‑blind crossover trial, participants taking 1,500 mg of the marc supplement showed a measurable reduction in triglyceride response after meals, while fasting triglycerides trended lower but were not statistically significant. The study also noted a modest rise in HDL‑C, suggesting a favorable shift in lipid profiles. Researchers attribute the effect to the whole‑food matrix of the marc, which retains both extractable and non‑extractable nutrients often lost in white‑wine processing.
