**6.2 All other vegetables**

Scientific evidence has shown the association between vegetable intake and its polyphenols for the prevention or treatment of diseases. The compounds in vegetables act to improve neuronal plasticity through the protein CREB (Camp Response Element Binding) in the hippocampus, modulating pathways of signaling and transcription factors (ERK/Akt). In the same way, brain-derived neurotrophic factor (BDNF) is involved in the maintenance, survival, growth, and differentiation of neurons. All these effects are produced by an increase in cerebral blood flow, with an upsurge in the blood's nitric oxide levels and oxygenation [25]. Terpenoids,

carotenoids, phenolics, phytosterols, and glucosinolates are the most prominent bioactive compounds existing in vegetables found to be operational in preventing neurodegeneration.
