Time-restricted eating shows no cardiometabolic benefit in real-world adults

A May 2026 systematic review and meta-analysis in the European Journal of Clinical Nutrition (Feit et al.) pooled 18 observational studies and found that a ≤12-hour daily eating window shows no significant association with abdominal obesity, metabolic syndrome, hypertension, HDL-C, triglycerides, or diabetes risk in community-dwelling adults. Two prospective nuances add precision: early eating (breakfast before 8 a.m. + >13h nightly fast) was associated with 53% lower T2DM incidence, and a U-shaped curve links both <10h and >14h fasting to higher mortality. The recommendation: prioritize established diet and lifestyle strategies first; if using TRE, front-load the eating window toward morning.

Whole fruit beats fiber for constipation

A May 2026 network meta-analysis of 19 RCTs in the American Journal of Clinical Nutrition found that whole multicomponent foods (kiwifruit, prunes, mango) and fruit-based interventions outperform fiber supplements and conventional laxatives for functional constipation — with HIGH-certainty GRADE evidence for stool consistency improvement. The article covers study design, a ranked evidence table, dose-response data for mineral water and kiwifruit, a full limitations section, and a concrete daily protocol: 2–3 kiwifruit, 8–10 prunes, and 0.5–1 L magnesium-rich mineral water.

Weight loss didn't improve AF symptoms in older adults — here's what that means for dietary advice

A multi-center UK RCT (LOSE-AF, JAMA May 20, 2026; n=118) found that an 8-month low-calorie diet producing 9.7% weight loss in older adults with persistent atrial fibrillation failed to improve AF symptom scores. Weight loss was real and safe — AF did not respond. The takeaway: dietary weight loss supports cardiovascular health in AF patients but should not be framed as a primary rhythm-control strategy in older adults with established persistent disease.

Do food preservatives raise heart disease risk?

A May 2026 European Heart Journal study of 112,395 French adults found that people with the highest intake of eight common food preservatives had 10–39% higher hazard ratios for hypertension and 16% higher CVD risk — but the study is observational, and the signal most likely reflects broad ultra-processed food consumption rather than preservatives themselves. The clearest action: cut processed meat, not the preservatives on the label.
