April 16, 2003 -- An herbal supplement made from green tea leaves might help fight diabetes.

The finding comes from researchers at supplement manufacturer Pharmanex. Hong Zu and colleagues overfed rats until their metabolism started to go haywire. When this happens to obese humans it's called metabolic syndrome X or insulin resistance..

A major feature of metabolic syndrome X is that the body starts losing control of blood sugar levels. In an effort to help, the pancreas makes more insulin. But the body becomes more and more resistant to insulin. Eventually, the whole system breaks down and diabetes, high blood pressure, and high cholesterol result.

Can green tea help? Pharmanex makes a green tea supplement called Tegreen. Zu's team gave the fat rats daily doses of Tegreen for eight weeks. Compared with rats that got no treatment, the Tegreen-taking rats lost abdominal fat. More importantly, they had lower levels of sugar, fat, and insulin in their blood.

"Oral administration of Tegreen is capable of improving glucose and lipid metabolisms induced by a high-calorie diet in an obese rat model," Zu and colleagues note in a news release. "This study clearly shows that Tegreen intervention can significantly decrease visceral fat depot and increase insulin sensitivity, presumably touching one of the pathological root causes of the potentially deadly syndrome."

Zu colleague Jia-Shi Zhu reported the findings at this week's meeting of the American Physiological Society.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
