Black Tea Shows Blood Sugar Benefits

Drinking black tea may be beneficial for people with diabetes, as it appears to stimulate an insulin response and reduce blood sugar levels, according to researchers from King‘s College London and the University of Central Lancashire.

Sixteen participants drank glucose in either water, water plus a small amount of caffeine, or water plus instant black tea.

After two hours, plasma glucose concentrations were significantly reduced in those who consumed 1 gram of tea, compared to the plain water and caffeine drinks. Drinking black tea also increased insulin levels compared with the other drinks, after 90 minutes.

Tea’s protective benefits have been linked to polyphenols, including:

 

     

     

  • Epigallocatechin gallate (EGCG)

     

     

  • Epigallocatechin

     

     

  • Epicatechin gallate

     

     

  • Epicatechin
These compounds may offer blood sugar benefits by stimulating B-cells -- pancreatic cells responsible for insulin production -- to produce insulin in your body, according to researchers.

Black tea makes up about 78 percent of the global tea market.

What Are GMOs?

From April 19th through April 25th we launch GMO Awareness Week. We set aside an entire week dedicated to providing you with information on GMOs and labeling initiatives.

GMOs are a product of genetic engineering, meaning their genetic makeup has been altered to induce a variety of “unique” traits to crops, such as making them drought-resistant or giving them “more nutrients.” GMO proponents claim that genetic engineering is “safe and beneficial,” and that it advances the agricultural industry. They also say that GMOs help ensure the global food supply and sustainability. But is there any truth to these claims? I believe not. For years, I've stated the belief that GMOs pose one of the greatest threats to life on the planet. Genetic engineering is NOT the safe and beneficial technology that it is touted to be.

Help Support GMO Labeling

The Grocery Manufacturers Association (GMA)—Monsanto’s Evil Twin—is pulling out all the stops to keep you in the dark about what’s in your food. For nearly two decades, Monsanto and corporate agribusiness have exercised near-dictatorial control over American agriculture. For example, Monsanto has made many claims that glyphosate in Roundup is harmless to animals and humans. However, recently the World Health Organization (WHO) had their research team test glyphosate and have labeled it a probable carcinogen.

Public opinion around the biotech industry's contamination of our food supply and destruction of our environment has reached the tipping point. We're fighting back. That's why I was the first to push for GMO labeling. I donated a significant sum to the first ballot initiative in California in 2012, which inspired others to donate to the campaign as well. We technically "lost the vote, but we are winning the war, as these labeling initiatives have raised a considerable amount of public awareness.

The insanity has gone far enough, which is why I encourage you to boycott every single product owned by members of the GMA, including natural and organic brands. More than 80 percent of our support comes from individual consumers like you, who understand that real change comes from the grassroots.

Thankfully, we have organizations like the Organic Consumers Association (OCA) to fight back against these junk food manufacturers, pesticide producers, and corporate giants.

Together, Let's Help OCA Get The Funding They Deserve

Let’s Help OCA get the funding it deserves. I have found very few organizations who are as effective and efficient as OCA. It’s a public interest organization dedicated to promoting health justice and sustainability. A central focus of the OCA is building a healthy, equitable, and sustainable system of food production and consumption. That's why I'm proud to announce I will be matching donations up to $250,000 this week.

Please make a donation to help OCA fight for GMO labeling.

Dr. Mercola's Comments:

Americans drink about 2.25 billion gallons of tea each year -- that’s about 132 cups of tea per person per year. While this sounds like a lot, you may actually need five to 10 cups of most green or black teas a day to reap many of their protective benefits.

Still, one of the active ingredients in tea, epigallo-catechin gallate (EGCG), really does show potential to fight a wide range of diseases, including:
Plus, a growing body of research suggests that the wonderful polyphenols in tea can lower your cholesterol, triglyceride levels and blood pressure, and even help to protect your bones.

I still believe that water should be your beverage of choice, and should make up the majority of your fluid intake, but adding tea to your day is a perfectly sensible choice for an additional beverage.

Do Your Homework on Your Tea Choices

Out of the seemingly endless varieties of tea out there, there are only a small handful that I would recommend drinking.

The first thing to watch out for is fluoride. Many conventional brands contain unsafe amounts of this health-harming chemical that has been linked to osteosarcoma, the most common kind of bone cancer. If you drink tea that is high in fluoride, your risks will outweigh your benefits, so please find a brand that will vouch for its low fluoride content.

You also need to choose tea that is grown in as nutrient-rich and clean a soil as possible. The majority of the world's green teas consumed today come from China, Pakistan, and India, which may have potentially toxic soil conditions.

Also be aware that high-quality green tea should, in fact, look green. If your “green” tea looks brown, it is not a high-quality tea. My current favorite green tea is called Matcha green tea, as it is the highest quality premium green tea and typically is reserved for royal tea ceremonies in Japan.

The other option for those of you looking to get the health benefits of tea without worrying about fluoride or contaminants is to try a high-quality tea extract that is fluoride-free.

Of course, if you decide to drink tea, make sure that you are simply drinking it “straight.” Avoid adding sugar, milk or other unhealthy additions, and certainly stay away from tea energy drinks, which are nothing more than chemical cocktails.
