For how we live.
A pooled analysis puts patient-reported rates at 13.9%, 8.0% and 12.0%. All of it is self-report, the heterogeneity is enormous, and the reviewers stop short of recommending avoidance.
A Copenhagen team has just published the protocol for the first study designed to test whether reducing PFAS exposure changes anything. That it is still a protocol tells you where the evidence stands.
The fear that a high-protein diet damages normal kidneys is not supported by the trial evidence. Protein restriction is a therapy studied in people who already have kidney disease — a different question entirely.
Two double-blind crossover studies in people who had put themselves on gluten-free diets failed to reproduce a gluten effect. One found a different wheat carbohydrate did it instead.
Feeding studies find that when fructose replaces other carbohydrate at equal calories, liver fat barely moves. The liver damage tracks the extra energy, not the sugar's molecular identity.
A parental history of acne carries a pooled odds ratio of 2.91. Dairy carries 1.25, from observational studies with demonstrated publication bias — and diet appears nowhere in the treatment guideline.
A network meta-analysis of 13 randomised trials put the diet ahead of every alternative for IBS symptoms. Its authors note the trials skipped reintroduction and personalisation entirely.
In 38,283 nurses tracked through the transition, low-insulinemic and planetary-health eating patterns had the strongest associations with less weight gain. The average woman still gained 0.8 kg a year.
On the unprocessed diet, participants built plates 57% heavier and 110 calories lighter. The authors argue that fruit and vegetables were crowding out calories on purpose.
Fifty-five English adults ate two eight-week diets that both followed the UK Eatwell Guide. Both produced weight loss. The minimally processed version produced about one percentage point more.
