Nutritional studies link tomato lycopene and fruit-vegetable ratios to health

Recent nutritional studies have highlighted the potential benefits of specific dietary patterns for brain function and longevity. A clinical study conducted by researchers at the University of Barcelona, published in the journal ‘Antioxidants’, suggests that lycopene—a powerful antioxidant found in tomatoes—may influence brain connectivity. After three months of consuming 35 grams of tomato paste daily, 42 healthy adults showed improvements in selective attention and associative memory. Brain scans from a subset of participants indicated a functional reorganization of neural networks, potentially leading to more efficient cerebral activity and increased levels of the protein BDNF.

Separately, research from the Harvard T.H. Chan School of Public Health, based on 30 years of data from over two million people, has identified an optimal ratio of fruit and vegetable consumption for preventing chronic diseases. The study suggests that consuming two servings of fruit and three servings of vegetables daily may provide significant health benefits. While the World Health Organization recommends at least five servings per day, researchers noted that leafy greens, citrus, and berries offer higher benefits compared to starchy options like corn or potatoes.
