In the brain, it may help curb oxidative stress and inflammatory processes, which also play a role in aging https://www.geo.de/wissen/gesundheit/tomatenmark-fuers-gehirn--studie-zeigt-ueberraschenden-effekt-38233332.html Tomato Intake Improves Cognitive Performance and Modulates Functional Brain Networks in Healthy Adults: A Randomized Crossover Clinical Trial https://www.mdpi.com/2076-3921/15/5/644 "Regular tomato consumption appears to enhance selective attention and associative memory in healthy middle-aged adults, potentially through antioxidant-mediated neurotrophic and neuroprotective mechanisms and targeted reorganization of functional brain networks. The specificity of these effects illustrates the capacity of nutritional interventions to modulate distinct cognitive processes and circuits. Together, these findings suggest that tomato consumption may help promote cognitive function in midlife"
