Tomato Improves Sleep Quality by Enhancing Levels of Melatonin

By Kyle J. Norton

Sleep is a naturally recurring state of mind and body in human, In sleep, most functions of the brain are reduced including the sensory activity, voluntary muscles are inhibited.

In other words, sleep is the state in which human reduced interactions with the outside world.

The human sleep recurrently to reenergize their body so that when awake they can carry out a daily activity without feeling tired or weak.

In the brain, sleep helps to maintain the pathways associated with brain function such as learning and studying. A recent study suggested, sleep helps to remove toxins in the brain that was built up when  awake.

Believe it or not, we spend about one-third of our life sleeping. 

Sleep disorders are syndromes associated negatively with the changes in the sleep pattern, including insomnia, one of the most common causes of disease disorders in the US, found in 30% of adults, including 10% of chronic insomnia is a condition of difficulty falling asleep or staying asleep throughout the night.

According to the statistics, 50-70 million US adults have a sleep disorder including 37.9% reported unintentionally falling asleep during the day.

Sleep disorders have been found to have a strong implication on economic cost. Dr. Hillman DR, the lead scientist at the Sir Charles Gairdner Hospital wrote, "The overall cost of sleep disorders in Australia in 2004 (population: 20.1 million) was dollar 7494 million".

And, "The direct and indirect costs of sleep disorders are high. The total financial costs (independent of the cost of suffering) of dollar 4524 million represents 0.8% of Australian gross domestic product. The cost of suffering of dollar 2970 million is 1.4% of the total burden of disease in Australia".

Tomato is red, edible fruit, genus Solanum, belongs to family Solanaceae, native to South America. Because of its health benefits, the tomato is grown worldwide for the commercial purpose
and often in the greenhouse.

On finding a natural and potential compound for the improvement of sleep quality, researchers investigated the effect of tomato intake before bed on obese postmenopausal women's urinary 6-sulphatoxymelatonin (aMT6s) level, a reliable surrogate biomarker reflecting the blood melatonin concentration and sleep quality.

The study is an 8-week open-label, randomized controlled dietary intervention trial included 36 subjects completed the entire trial.

In the tomato group, participants ate 250 g of beefsteak tomatoes 2 h before sleep for 8 weeks.

After 8 weeks, by comparing the blood and urine samples collected at the baseline and in the 8th week, researchers found at 8 weeks of the beefsteak intervention, improved all components of all components the PSQI compared to the Pittsburgh Sleep Quality Index (PSQI) before treatment.

Furthermore, tomatoes and beefsteak intervention also improved the levels of aMT6s level by 10-fold compared that of the control group.

In other words,  tomato combined with beefsteak improved the sleep quality of the participants.

These results strongly suggested that tomato enhanced the levels of melatonin in the beef substantially in the improvement of sleep quality.

Dr. Yang TH, the lead scientist at the Taipei Medical University wrote in the final report, "supplementation with beefsteak tomato before sleep can increase circulating melatonin and improve sleep quality in obese postmenopausal women".

Taken altogether, tomatoes combined with beefsteak may be considered treatment to improve sleep quality, pending to the confirmation of the larger sample size and multicenter human study.
