Eat cherries for a good night’s sleep

Cherries grown in sun-rich Central Otago are a natural source of melatonin at levels 30 times higher than their northern hemisphere counterparts.

If you are having struggling with sleep issues, Central Otago cherries could be the bedtime treatment, say researchers.

The findings come from research commissioned by Fruision Ltd, a joint venture between Hamilton-based Quantec Ltd, a company specialising in developing health treatments from natural products, and Alexandra-based fruitgrower Summerfrui, Stuff.co.nz reported.


Melatonin is a hormone that is naturally present in the human body and aids sleep.

The latest study, undertaken by an independent laboratory in Australia, has shown Central Otago cherries have 500 nanograms per gram.

Earlier studies published in the United States have shown northern hemisphere cherries to have levels of melatonin at to 15 nanograms per gram.

When the cherries had been dried, the melatonin levels increased to 3100 nanograms per gram.

Fruision senior scientist Dr Judy Bragger said Kiwi plants are exposed to more ultraviolet radiation than those growing at a similar latitude in Europe of North The united states, and this caused them to produce more secondary metabolites - organic compounds that are not directly involved in the normal plant growth.

"It is these secondary metabolites that the cherries produce that have such great human health promoting properties when eaten," Dr Bragger said.

Moanui Laboratories in Hamilton were already backing the science and are the first New Zealand company to distribute a sleep aid derived from cherries in a capsule form.
