Diet to reduce pain from diabetic peripheral neuropathy
The Treatment of Painful Diabetic Neuropathy With Diet, a Randomized-controlled Trial
This compares a whole-food, plant-based, no-added-oil diet with usual medications to see if it lowers pain and improves nerve symptoms in adults with painful diabetic neuropathy.

What this trial studies
This is a prospective randomized controlled study comparing a whole-food, plant-based diet excluding all animal products and added oils to optimized pharmacologic management over a two-month period. Participants in the diet group will eliminate meat, dairy, eggs, and added oils and will be offered an optional cooking class to support adherence. The control group will receive optimized medications (e.g., gabapentin, pregabalin, duloxetine, tricyclic antidepressants, or supplements like alpha-lipoic acid) with the option to cross over to the diet after two months. Inclusion requires type 2 diabetes or prediabetes, objective EMG/NCS evidence of peripheral neuropathy, and pain rated ≥4/10; the study is conducted without external funding.
Who should consider this trial
Good fit: Adults (≥18) with type 2 diabetes or prediabetes, objective EMG/NCS confirmation of peripheral neuropathy, and painful neuropathy with pain ≥4/10 who can consent and attend follow-up visits are ideal candidates.
Not a fit: Patients with non-diabetic causes of neuropathy (for example B12 or folate deficiency, thyroid disease, autoimmune or inflammatory disorders, HIV, toxin exposure, multiple myeloma, or significant lumbar stenosis), type 1 diabetes, or those unable to follow a strict plant-based oil-free diet may not receive benefit.
Why it matters
Potential benefit: If successful, the diet could reduce neuropathic pain, improve nerve blood flow and function, and decrease reliance on pain medications.
How similar studies have performed: A prior case series reported improvement in painful diabetic neuropathy with this diet and other research shows whole-food, plant-based diets can improve arterial disease, but randomized trials specific to PDN are limited.
