Ohio State scientist suggests dietary strategies for better sleep

Gary L. Wenk, a professor at Ohio State University, suggests that certain dietary components can support the mechanisms related to sleep onset and quality. While no single food can reset the brain's biological clock, specific nutrients play a role in the sleep-wake cycle.

Tryptophan is a key amino acid used by the body to produce serotonin and melatonin. To assist tryptophan in reaching the brain, Dr. Wenk suggests consuming foods rich in it—such as milk, chicken, fish, eggs, pumpkin seeds, legumes, and leafy greens—alongside simple carbohydrates. This combination helps insulin secretion alter the amino acid ratio in the blood to facilitate brain uptake.

Other beneficial foods include bananas, almonds, and walnuts, which provide magnesium and other elements that aid relaxation. However, Dr. Wenk warns against using high-dose tryptophan supplements without medical guidance, noting that excessive amounts have been linked to eosinophilia-myalgia syndrome.
