Plant-Forward EAT–Lancet Diet Linked to Reduced Chronic Kidney Disease Risk
A significant study published in the CMAJ (Canadian Medical Association Journal) indicates that adhering to a plant-forward diet, specifically the EAT–Lancet planetary diet, and limiting added sugars and fats, is associated with a reduced risk of chronic kidney disease (CKD).
Adhering to a plant-forward diet, specifically the EAT–Lancet planetary diet, and limiting added sugars and fats, is associated with a reduced risk of chronic kidney disease (CKD).
Globally, approximately 10% of adults are affected by chronic kidney disease. Projections suggest CKD could become the fifth leading cause of death worldwide by 2040.
The Study: UK Biobank Data Reveals Link
The study utilized data from the UK Biobank, a long-term study involving 179,508 eligible participants aged 40 to 69 across England, Scotland, and Wales. Dietary information was collected via questionnaires. Over a median follow-up period of 12 years, 4,819 (2.7%) participants developed CKD.
Dr. Xianhui Qin and coauthors from Nanfang Hospital, Southern Medical University, Guangzhou, China, stated that "greater adherence to the EAT–Lancet planetary health diet was significantly associated with a reduced risk of incident CKD." This protective association was particularly noted among individuals with limited residential green space exposure and specific genetic variations.
Understanding the EAT–Lancet Planetary Diet
While various plant-based diets, such as Dietary Approaches to Stop Hypertension (DASH) and the Alternate Mediterranean Diet (aMed), are promoted, the EAT–Lancet planetary health diet was developed with a dual focus. It integrates human health considerations with environmental sustainability. The diet emphasizes fruits, vegetables, legumes, and certain amounts of meat and dairy, while crucially restricting added sugars and fats.
Dietary Components for Kidney Health
The authors further explained that a common element among these beneficial dietary patterns is their focus on increased consumption of vegetables, fruits, and nuts, alongside reduced red meat intake. These components have consistently been linked to lower CKD risk in prior research.
The EAT–Lancet diet's distinct limitation on added sugars and fats may further reduce kidney risk by influencing inflammation and oxidative stress pathways. These findings suggest the EAT–Lancet diet as a potential effective dietary strategy for CKD prevention.
