Green Tea, Life Expectancy, and Type 2 Diabetes
By Pierre Mouchette | Bits-n-Pieces
Research over the last decade has examined the relationship between drinking green tea or coffee on mortality. The studies' results are consistent overall with other extensive research studies, with a significant relationship between the consumption of green tea and all-cause mortality. The higher the green tea intake, the lower the risk of death. Regularly drinking more than five cups of green tea a day reduces the risk of death by 15% compared to non-green tea drinkers. Research authors comment that the antioxidant effects of green tea polyphenols might underlie their findings.
Note: there are biologically acceptable reasons why consuming large quantities of green tea or coffee could benefit people who have type-2 diabetes and could help prevent cardiovascular disease and cancer.
The Human Body
Every day, the body's cellular processes result in electrically charged particles called reactive oxygen species (ROS). These particles are potentially dangerous molecules as they can damage DNA and initiate the production of cancer cells. The process known as oxidative stress underlies the development of many diseases seen today, such as heart disease (due to atherosclerosis), diabetes, dementia, and cancer.
The human body can protect itself from oxidative stress by eating a healthy diet, especially with antioxidants in massive quantities, mainly found in brightly colored fruit and vegetables. These antioxidants can neutralize ROS and prevent damage from oxidative stress. Green-tea polyphenols, in particular ECGC, are potent antioxidants.
Green tea - has a range of health benefits due to its high polyphenol content. The polyphenols in the leaves are primarily epicatechins and epigallocatechin gallate ECGC. These are plant substances that protect plants from cellular damage and are potent antioxidants. Green tea also contains L-theanine and caffeine, stimulant drugs.
Coffee - contains a mixture of caffeine, tannins, proteins, and oils. Studies indicate that chronic coffee consumption is associated with a lower risk of death from cardiovascular disease, a reduced risk of stroke, heart failure, and improved risk factors for cardiovascular diseases, such as diabetes. Together with many of the other constituents of coffee, caffeine is a potent antioxidant.
Can You Drink Too Much Green Tea?
Do not overdo it if you choose to begin drinking green tea. Excess green tea may cause nervousness, anxiety, nausea, and sleep problems. Drinking too much green tea can even be risky for people who already have severe cardiovascular disease. The effect of green tea on pregnancy and breastfeeding is unknown, but it is linked to miscarriages. Green tea may interfere with certain types of medication, for example, anticoagulants. Always check with your doctor if you are on long-term medication before changing your lifestyle.
Note: you should NOT drink more than eight cups of green tea per day, maximum. Adding a slice of lemon may aid in digestion. For those who do not like drinking green tea, consider green tea extract as a supplement
