As we delve deep into countless medical journals to uncover the latest on Integrative Medicine’s approach to kidney health, we are always reminded of the value of your time. Our commitment remains steadfast in curating and succinctly summarizing these vital studies for you. Welcome to the May Research and News.
Magnesium and Chronic Kidney Disease: An Essential Consideration
An expert article by our friend Lindsey Zirker, MS, RD in Renal & Urology News highlights magnesium’s underappreciated role in CKD management. Beyond regulating calcium and potassium, magnesium modulates inflammation, insulin sensitivity, and vascular tone. Yet serum levels may not tell the whole story—clinicians are encouraged to evaluate magnesium status more comprehensively, including dietary intake, medications (e.g., PPIs, diuretics), and intracellular levels (e.g., RBC magnesium).
Why is this important?
Maintaining magnesium within the optimal 1.7–2.3 mg/dL range could help mitigate complications in CKD. The choice of supplement matters—magnesium citrate, glycinate, or malate are preferred forms with better absorption and fewer GI side effects.
Proinflammatory Diets Linked to Higher CKD Risk
A review in the Journal of Health, Population and Nutrition analyzed 13 cross-sectional studies and found that individuals with higher dietary inflammatory index scores had significantly greater odds of CKD (OR 1.36) and reduced eGFR (OR 1.58).
Why is this important?
Dietary inflammation is modifiable. This evidence strengthens the case for anti-inflammatory dietary patterns—rich in fruits, vegetables, legumes, and omega-3s—in both prevention and management of CKD. Personalized nutrition approaches that assess dietary inflammatory load could help reduce progression risk.
Weight Loss Without Drugs or Surgery in Advanced CKD: What Works?
A new scoping review in Kidney Medicine reviewed 17 studies involving patients with stage 4–5 CKD and obesity. Non-pharmacological, non-surgical interventions—particularly caloric restriction diets supported by lifestyle coaching—produced meaningful weight loss (up to 7 kg or 15.4 lbs) with no reported adverse events.
Why is this important?
Obesity in CKD complicates transplant candidacy, increases cardiovascular risk, and worsens inflammation. This review supports a role for structured lifestyle programs in advanced CKD populations, challenging the belief that significant weight loss is unsafe or unachievable without surgery.

Drug-Induced Membranous Nephropathy: Mechanisms and Genetics
An in-depth review in JASN explores the pathophysiology of drug-induced membranous nephropathy, triggered by agents like gold salts, NSAIDs, mercury, D-penicillamine, lipoic acid, and thiol-containing drugs. The review notes variable T-cell responses and genetic susceptibility in animal models.
Why is this important?
Understanding the immune-genetic interface in drug-induced nephropathy may lead to personalized risk assessment and earlier intervention. Integrative providers should review all supplements and medications in patients with unexplained proteinuria.
Ultra-Processed Foods and Premature Death: A Call for Reform
A large epidemiologic study in the American Journal of Preventive Medicine (reported by CNN) found that each 10% increase in calories from ultra-processed foods was associated with a 3% higher risk of premature death. The U.S. leads global consumption, with nearly 55% of calories coming from these foods.
Why is this important?
This study reinforces how dietary quality, not just nutrients, but also food processing, directly impacts longevity. For CKD patients, reducing ultra-processed intake could reduce mortality, cardiovascular events, and mental health disorders.

Gut-Liver-Kidney Axis and Metabolic Disease: Microbiome at the Center
A CJASN perspective piece explores how gut dysbiosis, small intestine bacterial overgrowth, and gut-derived metabolites link MASLD (formerly NAFLD) and CKD. Emerging omics-based research reveals overlapping inflammatory and metabolic pathways.
The gut-kidney axis remains a promising target for intervention. A comprehensive gut restoration protocol and microbiome-targeted therapies may offer multi-organ benefits in patients with metabolic dysfunction. This piece adds weight to the integrative focus on gut health in chronic disease.
