  1. 1. The Benefitsof Green TeaHW499 Unit 4 PresentationKaplan UniversityJennifer Lee
  2. 2. How common is Green Tea use? Raise your hand if you have ever drank a beverage or taken pills that contained green tea. It is more common than you think. The facts about the benefits and risks associated with this herb is not openly shared with the public through product advertisements (NCCAM, 2005).
  3. 3. History of Green Tea Green tea and its extract EGCG have been known to be used to fight against breast, stomach and skin cancer. They also were used for alertness, to lower cholesterol level, weight loss, and to protect the skin against sun damage (NCCAM, 2005).
  4. 4. Facts Green tea is produced by the Camellia Sinensis plant. Its leaves are essentially steamed before they are dried, in order to produce the product. Green tea is found to be safe for adults if taken in moderate amounts (NCCAM, 2005). The caffeine content of green tea is 8-30 mg/per cup. To put it into perspective, an average cup of coffee has 100-135 mg of caffeine (Time for Tea, 2004). Two to three cups a day is the recommended amount (University of Maryland Medical Center, 2011).
  5. 5. Green Tea in regards to Science Certain laboratory results suggest that the use of green tea may protect completely against or slow the growth of different kinds of cancer in animals. For humans in the study, the results were mixed. Studies have found that the use of green tea can aid in an increase in mental alertness. This is most likely due to the caffeine content (NCCAM, 2005).
  6. 6. Green Tea in regards toScience Cont’d Green tea contains flavonoids which are plant derived compounds that happen to be antioxidants. Antioxidants neutralize the specific activity of free radicals (unstable molecules), which have been known to damage DNA. Green tea is the best food source of specific flavonoids called catechins that prevent oxidative damage to cells. They also have other disease fighting properties that are being studied. In order to get the full benefits, green tea must be consumed as freshly brewed. Decaffeinated, instant teas, or bottle substitutes do not have the same benefits (Time for Tea, 2004). Laboratory experiments on animals and humans have also found that green tea positively impacts: inflammatory bowel syndrome, diabetes (regulates glucose), liver disease, dental cavities, arthritis, genital warts, and prevents cold and flu symptoms (University of Maryland Medical Center, 2011).
  7. 7. Green Tea in regards toScience Cont’d Green tea also contains theobromine, theophylline, along with caffeine. These alkaloids help produce the stimulant effect. There are dried leaf and liquid extracts that are in capsule form. There are many dietary supplements that come in this form. Many of them are not FDA approved due to the extracts being modified to have a more powerful affect (higher doses of caffeine for example) (University of Maryland Medical Center, 2011).
  8. 8. Positives of Green Tea Green tea blocks the oxidation of LDL cholesterol (the bad kind) and increases HDL cholesterol (the good kind). It improves overall artery function. Scientific studies that had these findings, supported the claims that green tea improves cardiovascular health by reducing the risk of heart disease and hypertension (Time for Tea, 2004).
  9. 9. Negatives of Green Tea There are known cases of individuals with liver disorders or problems that took concentrated extracts of green tea. Green tea and the extracts are known to contain caffeine which could cause: irritability, insomnia, anxiety, upset stomach, nausea, diarrhea, and frequent urination. This occurs if taken in large amounts or if the consumer is prone to these symptoms (NCCAM, 2005). When green tea is taken in large amounts it can interfere with blood clotting and interact with blood thinners (University of Maryland Medical Center, 2011).
