New Study Finds Higher NAD+ Levels in Vegans Linked To Slower Aging

A recent study published in Nutrition Research suggests that vegans may have higher NAD+ levels compared to other dietary groups, which is a key biomarker linked to cellular aging. Mic the Vegan breaks down the study findings, highlighting the significant difference in NAD-to-NADH ratios between vegans, vegetarians, omnivores, and low-carb high-fat eaters. Vegans had the highest ratio, indicating more efficient mitochondrial function and less oxidative stress, which are associated with healthier aging.

The study also found that vegans consumed more dietary fiber, antioxidants, vitamin C, and whole grains, which were positively correlated with better NAD+ levels. In contrast, total fat and saturated fat intake showed negative associations with the NAD ratio. Despite the buzz around NAD supplements, the research suggests that boosting NAD levels through diet, specifically plant-based foods, may be more beneficial for healthy aging. Overall, the study highlights the potential benefits of a vegan diet in supporting healthier cellular aging.
