Cut your risk of cognitive decline by up to 86 percent!

Make no mistake about it: If there were a drug that could cut the risk of cognitive decline in HALF, it would be the top story on the nightly news.

But there IS something that can do the trick, and it's getting no media play at all.

It's simple, safe, and delicious -- and odds are, you have it sitting in a kitchen cupboard right now.

It's TEA!

Whether you like black, green, or oolong, a cup a day can keep cognitive decline at bay and can help protect against the condition even if you're already at high risk of Alzheimer's disease.

Overall, drinking tea regularly will cut your risk of cognitive decline in half.

Good, right? But some folks get an even bigger boost.

If you've had a genetic test, you might know if you're carrying APOE-4, a common mutation that makes you especially vulnerable to Alzheimer's.

It can increase your risk of the disease by as much as TWELVE times.

Drink tea, however, and you can cut that risk back down to size.

If you're carrying APOE-4 and all the risks that come with it, get brewing -- because the study finds tea will slash your risk of cognitive impairment by 86 percent.

The main reason for all that protection is almost certainly the brain-friendly antioxidants found in every cup of freshly brewed tea -- especially catechins, theaflavins, thearubigins, and L-theanine.

These compounds can fight inflammation and boost circulation, two key weapons in the battle to protect your brain from the ravages of age and disease.

And that's really only the beginning of the benefits.

Those same compounds can also help protect your heart, prevent stroke, and fight cancer. And if you've already had cancer, tea -- especially green tea -- can help make sure it never returns.

There is just one caveat with tea: It matters where it's grown.

Tea roots are like little sponges that suck up everything in the soil, and not just the water and minerals the plant needs to grow.

If there are metals in the ground, they will end up in the leaves.

As a result, tea leaves can contain low levels of lead, cadmium, arsenic, fluoride and more.

This can happen even in organic tea if they are grown in polluted areas, so beware of anything from India and China in particular. Ideally, stick to organic teas grown in the United States when possible.
