Bananas, corn and oats supply melatonin but in considerably smaller amounts.
Beyond the benefits of helping to reset the body’s internal time clock to treat
jet lag, melatonin also may be helpful for late-shift workers trying to adjust to a new
schedule. Increasing melatonin also has been shown to help with sleep-onset
insomnia in older adults with a melatonin deficiency.
“During adulthood, blood levels of melatonin begin to decline and by age 60,
levels can be significantly lower, which may account for the sleep disturbances that
often occur with aging,” Reiter said. “If eaten regularly, tart cherries may help
regulate the body’s natural sleep cycle and increase sleep efficiency, including
decreasing the time it takes to fall asleep.”
Increasing melatonin may do more than promote a restful sleep. Melatonin is
a potent antioxidant that has been extensively studied in recent years for its role in
reducing inflammation and fighting free radicals in the body, which is linked to
increased cancer risk.
A new study published in the journal Free Radical Research that was
conducted by Reiter and colleagues at the University of Granada in Spain found that
melatonin neutralizes the oxidative and inflammation process caused by aging,
thereby suggesting that melatonin may play a role in delaying the effects of aging.
Based on the findings of this study, the authors suggest that daily melatonin
intake in humans from the age of 30 or 40 could potentially help delay illnesses
related to aging.
