NCT07509671
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.

Vegan Diet and Immune-Inflammatory Outcomes in Asthma and Healthy Adults
This randomized controlled study evaluates the effects of a balanced vegan diet compared with a balanced omnivorous diet on inflammatory and immune response markers and clinical asthma parameters in healthy adults and individuals with mild to moderate asthma, aged 18 to 50. Participants will follow assigned dietary plans for 12 weeks with dietitian support delivered via digital tools.

Analysis of NfL and GFAP in Different Dietary Patterns
This observational study aims to investigate the impact of different dietary patterns on brain tissue biomarkers in healthy young adults by measuring blood levels of NfL and GFAP. The primary research question is: Do vegan, vegetarian, or omnivorous diets influence NfL and GFAP levels?

Effect of Vegan Diet on Microbiome and Metabolism
The goal of this interventional study is to investigate how vegan diet affects health in healthy volunteers, Men and women ages 20 - 30 years old. The main questions it aims to answer are: Change in Microbial community composition and metabolic alterations Changes in plasma metabolic profile. Researchers will compare changes in microbiota and plasma metabolites profile to see the influence of vegan diet in health. In the dietary trial, participants were first assigned to a 2-week omnivorous diet phase, then switched to a 2-week vegetarian diet phase

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?

Vegan Diet in Small Children
Following increased knowledge about climate change and how food production affects greenhouse gas emissions, the interest in vegetarian diets is increasing. In line with this, also vegan diet is becoming more common at all ages, including in young children. But the state of knowledge regarding the effect of this diet on children during infancy and early childhood has been poorly studied and existing literature consists to a large extent of case reports. With the main hypothesis that vegan diet from the introduction of complementary foods causes reduced bio availability of certain micronutrients important for development, the aim of this study is to examine dietary intake and development during the first years of life in a group of children eating vegan diet and compare with a reference group eating mixed diets. In an observational study, investigators plan to include 30 children before the age of 6 months during the years 2021-2026, where the parents have decided to offer their child only vegan food. The children are studied in comparison with a reference group of 30 matched cases regarding growth, nutritional status, and dietary intake. Data collection includes monthly dietary records and blood sample analyses and growth at 6, 12 and 24 months. At the age of 3, cognitive developmental assessment (WPSSI-IV) and an DEXA examination of body composition are performed. The study is expected to contribute to increased knowledge about the risk and benefits of vegan diets and thereby provide a better basis for future recommendations.
