The investigation highlights how specific nutritional components like lycopene can yield measurable changes in human brain scans and cognitive function over a relatively short three-month period. Medical discussions continue to focus on missing nutrients and the broader health implications of these dietary adjustments.

   What is confirmed

   • Forty-two adults ages 40 to 55 scored modestly better on attention, processing speed and associative memory tests after eating about two tablespoons of tomato paste daily for three months.
   • Researchers in Spain found that participants who ate about two tablespoons of tomato paste every day for three months scored slightly higher on tests of concentration, processing speed and associative memory than when they followed a diet low in lycopene.
   • Tomatoes contain lycopene, a naturally occurring red pigment with antioxidant properties.
   • The randomized crossover trial had participants complete both a low-lycopene diet and the daily tomato paste regimen.

   Still unconfirmed

   • Long-term outcomes of daily tomato paste consumption remain under ongoing observation by specialists.
