Drop for drop, it's hard to top green tea when it comes to health benefits. The drink has been shown to help fight cancer, boost the immune system, and even help you to live longer.

And now, a new study shows that it can keep you active and on your feet -- especially if you're getting up there in years.

Japanese researchers tracked nearly 14,000 seniors for up to three years, and found that those who drank the most tea were a third less likely to battle disability -- including problems with everyday life, such as bathing or dressing -- than those who drank the most.

This being Japan, however, the people who drank the most drank quite a bit -- five cups a day (those who drank the least, on the other hand, had less than a cup on average). That's a lot of tea, but you don't have to drink that much to benefit. In fact, three cups a day reduced the risk of disability by a quarter.

The study in the American Journal of Clinical Nutrition doesn't show why green tea helps keep seniors active and independent, and part of the reason is almost certainly because the tea drinkers in the study had healthier lifestyles overall.

But that's not the only reason -- because green tea is packed with powerful antioxidants that have shown to boost health and ward off disease before, including epigallocatechin gallate.

That's a name that was designed to trip tongues, so we call it EGCG for short -- and studies have shown that this stuff can reverse the cell damage linked to illness and disease.

Green tea has also been shown to fight cancer, gum disease, stress, depression, pneumonia, and more. It can also boost your immune system, lower your levels of bad cholesterol, reduce your stroke risk, ward off dementia, and even help you to lose weight.

It's about as close to a "magic" elixir as you'll find -- so go and brew yourself a cup or five today.
