Green tea was the subject of our last post, and we discussed how green tea can make your heart and cardiovascular system healthier. Today we look at some of the other health benefits of green tea.
Nutrition scientist Dr. Christopher Ochner, from Mount Sinai Hospital in New York City, says tea “Is the healthiest thing I can think of to drink”. He also notes that if you drink a can of sugared soda per day and substitute green tea instead, over a year you would save over 50,000 calories. That could mean a 7 kilogram weight loss.
The principal reason that green tea is so healthy is that it is full of antioxidants called polyphenols, which help stop the damage from free radicals that contribute to cellular damage and aging. Tea, more than most any other food, contains many different types of these antioxidant polyphenols in one substance. While it also also contains a variety of vitamins and minerals, the key differential of tea is that by weight, 20% to 45% is the polyphenol content.
Here is a summary of some of the other health benefits. This list is from the University of Maryland Medical Center and the University of Michigan Medical School. While these benefits are not proven, and some are controversial, the overall conclusion is that tea is likely helpful in the following areas (heart and blood vessels benefits were discussed in the previous post)
8 benefits of green tea
1) Cancer prevention
The cancers with the most evidence for a tea-protective effect are bladder, breast, ovarian, colorectal, esophageal, liver, stomach, pancreas, lung, pancreas, skin, and prostate.
Green tea has been shown to help regulate blood sugar levels and may cut the risk of developing diabetes.
3) Rheumatoid arthritis
The antioxidants in green tea act to suppress inflammation, which is the hallmark of rheumatoid arthritis.
4) Dementia and Alzheimer’s disease
By preventing the buildup of atherosclerotic plaques in the blood vessels of the brain, tea may help slow degenerative brain disease.
5) Dental cavities and bad breath
The antioxidant catechins in the tea inhibit the growth of certain bacteria in the mouth that lead to gum disease, cavities, and bad breath.
6) Inflammatory bowel disease
The anti-inflammatory effects of tea may diminish flare-ups of this colon disease as well as the related Crohn’s disease.
7) Liver protective
Green tea may help protect the liver from some of the toxic effects of alcohol, and reduce the risk of liver tumors.
8) Osteoporosis prevention
Animal and human studies suggest that tea decreases the breakdown of bone cells so common in older women and men.
So we all have lots of reasons to drink green tea daily. Make sure you don’t add sugar, which will negate some of the positive effects and add calories. The somewhat bitter taste is due to the antioxidant content, so it’s not a bad thing. As it is, plain green tea, while absolutely full of good things, has essentially zero calories.
