Beware The Tea You Sip

Green tea has become the beverage of choice for people who want to live a long, healthy life. And the latest studies prove its power to fight cancer, Alzheimer’s disease and a host of other ills.

But as usual, Big Food has jumped on the bandwagon to make money by hawking poor-quality tea in pretty bottles.

In their relentless drive for profit, drink makers have churned out dozens of brands of bottled green tea with the aim of cashing in on the beverage’s reputed healing power.

The trouble is that almost all of these teas are a waste of good water – because Big Food’s processing has stripped of most powerful ingredient in green tea.

Green tea has a centuries-old reputation for healing the mind and body. Its powers come from antioxidants called catechins.

And the most potent catechin in green tea is epigallocatechin-3-gallate, or EGCG for short.

Researchers at Penn State University recently used an extract of EGCG to kill oral cancer cells. And they discovered the antioxidant caused the cancer cells to self-destruct – and it even protects healthy cells while doing it.¹

And researchers at the University of Missouri tested EGCG in mice and found that the antioxidant significantly reversed the brain damage caused by Alzheimer’s.²

Studies over the past decade have also documented EGCG’s power against obesity,³ diabetes,⁴ cardiovascular disease^5,6 and Parkinson’s disease.^7,8

Despite numerous studies showing EGCG’s potency as a healer, the FDA has condemned its inclusion in a number of products. And Big Pharma has ignored it, because it’s a natural substance and can’t be patented.

Meanwhile, studies have also shown that as a scavenger of free radicals, EGCG can prevent and repair cell damage. It also combats the effects of pollution, sunlight and smoking on skin.

But when you buy green tea in a bottle, you will most likely end up sipping overpriced, caffeine-laced, sugar water with barely any of the brew or its antioxidants.

A report by ConsumerLab.com, the independent tester which verifies the quality of many of my own products, recently revealed the truth about four brand-name, bottled green teas.^9,10

Only one brand, Harney & Sons Organic Green, delivered 46.8 mg of EGCG, which is close to my recommended dosage. In the three other brands, EGCG measured significantly lower – and one, Diet Snapple Green Tea, came in as low as 3.5 mg. The home-brewed teas that were tested ranged up to 86 mg., although some were as low as 25 mg.

I recommend you get 50 mg. of EGCG a day. But you should get the antioxidant from supplements rather than tea. You can find these supplements online or at your local health food store.

I say this for two reasons. One, it’s hard to know if your tea will deliver enough of the antioxidant. Two, many green tea leaves have been contaminated with lead. The most contaminated leaves come from China. The least contaminated come from Japan.

If you do brew your own tea, then use a tea bag or tea leaves and a strainer to reduce the chances of lead leeching into your drink.

To Your Good Health,
