Nutrients, 17(5), 884. https://doi.org/10.3390/nu170508842072-6643http://hdl.handle.net/11268/14650The global shift towards vegan and vegetarian diets has garnered attention for their ethical, environmental, and potential health benefits. These diets are often rich in phytonutrients and antioxidants, which have been associated with lower levels of inflammatory markers, such as C-reactive protein (CRP) and interleukin-6 (IL-6), suggesting a potential protective effect against systemic inflammation and oxidative stress. This review critically evaluates the influence of these dietary patterns on neurological outcomes, emphasizing their nutritional composition, potential deficiencies, and their interplay with inflammation and oxidative stress.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article10.3390/nu17050884open accessCiencias médicasNutriciónNeurologíaGoal 2: Zero HungerGoal 3: Ensure healthy lives and promote well-being for all at all agesGoal 12: Ensure sustainable consumption and production patternsGoal 13: Take urgent action to combat climate change and its impactsGoal 15: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss
