  • Maintain healthy weight and minimize abdominal fat

Green Tea has numerous beneficial effects on the body. As compared to black tea, green tea contains a high level of catechins, a type of polyphenol, an antioxidant. The catechins in black tea are lost during processing.1

Green Tea Extract (GTE) contains the concentrated beneficial agents of green tea. Green Tea Extract contains ECGC (epigallocatechin-3-gallate), a powerful antioxidant with neuroprotective activity, and contains other protective polyphenol catechins.2

Green tea supports a strong healthy immune system.9 T cells are critical for healthy immunity. EGCG has been shown to increase T cell activity in the spleen and lymph nodes.10

GTE increases antioxidant capacity in the body and helps maintain a healthy BMI.3,4 Abdominal fat contributes to the risk of heart disease. The catechins in green tea can enhance exercise-induced abdominal fat loss, thereby helping minimize belly fat and protecting your heart.7,8

EGCG also appears to help the body utilize fat, while simultaneously minimizing the absorption of fat. The combined effect serves to slow down weight gain.11

The oxidation of low-density lipoprotein cholesterol (LDL-C) is the first step of dangerous "vulnerable" plaque formation on blood vessel walls. GTE reduces LDL oxidation.5According to a meta analysis, green tea can help maintain reduced LDL and total cholesterol levels.12

In addition, high levels of iron in the blood, particularly in combination with elevated levels of LDL, promote the oxidation of LDL. Green tea extract reduces iron levels in the blood.6 GTE may also reduce fibrinogen, a protein in the blood that contributes to coagulation.

Scientists are studying how EGCG from green tea related to pancreas function. An initial mouse study indicates that the extract may help support glucose levels already within a normal range.13 The evidence is inconclusive and more research is needed in this area.

According to the Ray & Terry Longevity Program, optimal blood pressure is less than 120/80. If your blood pressure is over this level, we recommend starting with a nutritional and supplement program as listed in Chapter 15 of Fantastic Voyage.
