The Treatment of Painful Diabetic Neuropathy With Diet

The purpose of this clinical trial is to determine whether targeted nutritional changes can improve symptoms of painful diabetic neuropathy. Impaired blood flow to peripheral nerves-resulting in reduced oxygen delivery and subsequent nerve injury-is a well-established contributor to neuropathy. Prior studies have shown that a whole-food, plant-based diet without added oils can improve or even reverse arterial disease, suggesting a potential mechanism for enhancing nerve perfusion and function. This study is a randomized controlled trial comparing a whole-food, plant-based diet with standard pharmacologic management for painful diabetic neuropathy.

Influencing a Vegan Diet and the Intake of Dietary Supplements During Pregnancy and Childhood

The main goals of the exploratory, cross-sectional survey among vegans are to reveal influencing factors, sources of information gathering, reasons for choosing certain dietary supplements of pregnant vegans and parents, difficulties in administering dietary supplements to children, and the compliance of dietary supplements of vegans, because there is no data available yet. Results serve as a starting point for comprehensive information provision for surveyed vegans and provide insight into the nutritional knowledge of vegans. The advisory role of the medical experts is essential to provide vegans with reliable information on a balanced vegan diet and dietary supplements. The opinion of medical experts has a decisive influence on the health of vegans. For this reason the content of their advice will be assessed. The main questions the study aims to answer are: Do vegan pregnant women and parents know about possible nutrient deficiencies during pregnancy and childhood and who do they turn to for information about nutritional supplements? What is the quality of the information received?
