Pomegranate-date combo could improve cardiac health, study finds

A four-ounce glass of pomegranate juice with three dates could protect against the build-up of lipids on the arterial walls by as much as 33 per cent, reducing chances for a heart attack.

Pomegranate juice and dates make a dynamic duo in the war on heart disease because their respective phenolic antioxidants work differently, according to lead author Professor Michael Aviram.

The key ingredients in pomegranate juice, he says, are plant-derived polyphenolic antioxidants that slow the body’s oxidation process, thereby reducing oxidative stress.

Dates contain phenolic radical scavenger antioxidants, which hinder the oxidation of low-density lipoprotein (LCL) cholesterol, also known as “bad-cholesterol.”

These scavenger antioxidants found in dates also stimulate the removal of cholesterol from arterial cells that come into contact with lipids, according to Professor Aviram.

Working with arterial cells in laboratory cultures, and with mice whose cholesterol levels were high, Professor Aviram’s team tested the combination of pomegranate juice and dates — using a cocktail that included their pits, which had been ground up.

The cocktail reduced oxidative stress in the arterial wall by 33 per cent and decreased arterial cholesterol content by 28 per cent, according to the study, which was published in the journal Food & Function.

Even without the pits, says Professor Aviram, the combination of dates and pomegranate is powerful and preferable to eating either fruit alone, but ideally the pits should be ground into a paste and consumed.

Pomegranate juice has long been hailed for its high antioxidant component and health benefits.

In 2010, a research team from the University of California at Riverside identified phenylpropanoids, hydrobenzoic acids, flavones and conjugated fatty acids as ingredients that keep cancer from spreading.

They do this by inhibiting the movement of the cancerous cells, weakening their attraction to a chemical signal that favours their attachment to the bone, bone marrow, lungs and lymph nodes, which usually results in death.

That study was presented in December 2010 at the annual meeting of the American Society for Cell Biology in Philadelphia, Pennsylvania in the US.

According to the Mayo Clinic, other foods that lower LDL cholesterol include high-fibre fare such as oatmeal, oat bran, kidney beans, apples, pears and barley.

Don’t forget about foods high in Omega 3s such as salmon, mackerel, lake trout, herring, sardines, albacore tuna and halibut, which they say can also lower cholesterol.

Nuts such as almonds or walnuts contain polyunsaturated fatty acids that can lower bad cholesterol, while olive oil’s antioxidants can also help keep your blood vessels healthy if consumed in moderation.
