Brassica refers to a genus of plants that includes broccoli, cabbage, kale, Brussels sprouts, and other cruciferous vegetables. There is scientific evidence supporting the role of Brassica vegetables in aging prevention, mostly due to their high content of bioactive compounds such as glucosinolates, sulforaphane, antioxidants (e.g., vitamin C, carotenoids), and polyphenols. These compounds are known to reduce oxidative stress and inflammation, two processes closely linked to aging and age-related diseases.

Several epidemiological studies have found that higher intakes of Brassica vegetables are associated with lower risks of cardiovascular disease, certain cancers, and all-cause mortality, which are key components of healthy aging. Research on sulforaphane, in particular, has shown it can activate pathways related to cellular defense and detoxification, and may improve mitochondrial function, which tends to decline with age. Animal studies suggest that Brassica-derived compounds can extend lifespan or healthspan, although direct evidence in humans is less robust.

While there is no conclusive evidence that Brassica vegetables directly prevent aging itself, the scientific consensus supports their inclusion in the diet as part of an overall strategy to reduce age-related decline and promote longevity. Therefore, the use of Brassica for aging prevention is supported by moderate scientific evidence, with ongoing research needed to clarify the extent of its benefits in humans.
