The latest health panacea and longevity aid is a very unlikely one — “heavy” water.

Heavy water (HW) occurs when the hydrogen atom — the “H” in H2O — is an isotope of normal hydrogen called deuterium. Deuterium weighs twice as much, hence the “heavy” tag.

Apart from the odd chemistry lesson at school, most people will know about heavy water from the film Heroes of Telemark, a wartime adventure in which Richard Widmark leads a British raid on Telemark in Denmark. The aim is to destroy a heavy water plant which threatens London with an atom bomb attack.

According to scientists the consumption of HW adds 10 percent to the lifespan of earthworms and 30 percent to other species. Humans are thought to be in for an extra 10 years of life if fed HW products, which can include bread, cakes or even pork from pigs fed with the water.

However, a close reading of the reports indicates that HW works by strengthening cells against free radical damage. Regular readers of Sideways Health will know that we are already well armed with a great many antioxidants in highly coloured fruit and vegetables that perform the same task.

It’s not clear whether heavy water adds to that effect or, to use a pun, will be swallowed up in it. In other words, will HW be wasted on folk who already consume 6000 ORAC of antioxidants a day?

We will keep an eye on this story to see how it develops.

Research shows that drinking a glass of cherry juice a day offers the same health benefits as 23 portions of fruit and vegetables.

The catch is that it only applies to American Montmorency tart cherries.

British and European varieties only seem to contain about 20 percent of the antioxidant levels of the U.S. fruit — however, the juice can be bought in the UK in health food stores, under the name of CherryActive.

The research by Dr Robert Verkerk, compared the Oxygen Radical Absorbance Capacity (ORAC) of 25ml of diluted cherry juice concentrate with various fruits and vegetables. The result was an overwhelming thumbs-up for the cherries.

A leading British nutritionist, Patrick Holford said, “A recent BBC2 Horizon documentary showed the longest-living people in the world all achieve a very high intake of antioxidants, measured as over 6,000 ORAC units a day.”

One glass of Montmorency cherry juice contains 8,260 units.

Life really is a bowl of cherries, it seems.

It’s said of some things that “You either love them or you loathe them”. Marmite comes to mind.

With broccoli, though, I’ve never met anyone who even likes it, let alone loses their heart to its sulphurous odours while cooking.

President Bush Senior famously declared his distaste for the vegetable, only for the American Broccoli Growers Association to dump a ton of the stuff outside the White House.

Broccoli is a part of the brassica family, which includes cabbages, sprouts and other green leafy growths. It contains a whole load of antioxidants as well as substances that absorb poisons from the system. It’s said to be particularly effective when served with cauliflower, another brassica.

But if you just hate it, here’s what you do.

Try blending it down raw with added water in a food processor. The green drink should then be made even more palatable by adding liquified apples and sweet red carrots.

Take a glass fresh every morning before breakfast for a healthy start to the day.
