MONDAY, June 10, 2024 (HealthDay News) — A higher Planetary Health Diet Index (PHDI) is associated with a lower risk for total and cause-specific mortality, according to a study published online June 10 in the American Journal of Clinical Nutrition<\/em>.<\/p>\n Linh P. Bui, M.D., Ph.D., from the Harvard T.H. Chan School of Public Health in Boston, and colleagues developed a PHDI to quantify adherence to the EAT-Lancet reference diet and examined associations between PHDI and total and cause-specific mortality in three prospective cohorts: 66,692 women from the Nurses’ Health Study; 92,438 women from the Nurses’ Health Study II; and 47,274 men from the Health Professionals Follow-up Study. Using a semiquantitative food frequency questionnaire, the PHDI was calculated every four years.<\/p>\n A total of 31,330 deaths were documented among women and 23,206 among men during up to 34 years of follow-up. The researchers found that the pooled multivariable-adjusted hazard ratio was 0.77 for all-cause mortality comparing the highest with the lowest quintile of PHDI. The PHDI was associated with a lower risk for deaths from cardiovascular diseases, cancer, respiratory diseases, and neurodegenerative diseases (hazard ratios, 0.86, 0.90, 0.53, and 0.72, respectively). The PHDI was also significantly associated with a lower risk for death from infectious diseases in women but not men (hazard ratio, 0.62). Inverse associations were seen for PHDI scores with greenhouse gas emissions and other environmental impacts.<\/p>\n “Our results support reductions in death from a variety of diseases with increasing adherence to a healthy and environmentally sustainable dietary pattern described by the EAT-Lancet Commission,” the authors write.<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n Editorial (subscription or payment may be required)<\/a><\/p>\n <\/i><\/p>\n
