Spanish Study: Tomato Sauce Boosts Memory Over Three Months
A three-month Spanish study of 42 adults found that daily consumption of concentrated tomato sauce improved memory and focus, likely through increased lycopene levels and enhanced brain connectivity. Researchers caution that larger studies
A Spanish research team reports that consuming 35 grams of concentrated tomato sauce daily, or approximately two tablespoons, for three consecutive months may improve memory and focus through changes in lycopene levels and brain network connectivity.
Spanish researchers studied the effect of tomatoes on cognitive function in 42 healthy middle-aged adults. One group received tomato sauce supplements while the other restricted high-lycopene foods such as tomatoes, watermelon, papaya, grapefruit, and guava for three months.
Results showed that the tomato sauce group had increased lycopene levels and showed improved ability to focus and associative memory, such as remembering the connection between names and faces. Lycopene, a natural antioxidant that gives tomatoes their red color, was a key compound of interest to researchers.
The research also found that consuming tomatoes is linked to nerve cell growth, brain cell network development, brain plasticity, and memory processes.
Researchers noted that these findings provide preliminary evidence connecting increased lycopene to changes in brain function, but cannot yet confirm that lycopene alone causes improved memory or focus. Since tomatoes contain many other vitamins and antioxidants, larger studies with longer follow-up periods are needed to verify whether tomato sauce significantly and consistently improves brain function.
A separate finding from the research indicates that the brain can maintain full focus for only four hours per day, and taking breaks every 50 minutes does not improve this.
