13 Reasons Tea Is Good for You

Ever
since 2737 B.C., when Chinese legend says leaves from an overhanging Camellia sinensis
plant fell into Emperor Shen Nung's cup of boiling water, tea has been
recognized by cultures around the world for its capacity to soothe, restore and
refresh. In December 2013, The American
Journal of Clinical Nutrition issued a Supplement addressing the research that
was presented at the Fifth International Scientific Symposium on Tea and Human
Health. During the symposium research
conducted from 2007 to 2012 was shared.
But before loading up on Red Zinger, make
sure that your “tea” is actually tea. Real tea is derived from the plant
Camellia sinensis and includes only four varieties: green, black, white, and
oolong. Anything else, like herbal “tea”, is an infusion of a different plant
and isn’t technically tea. But what real
tea lacks in variety, it makes up for in its health benefits. Tea’s health
properties can be attributed to polyphenols, a type of antioxidant, and
phytochemical. Though most researchers focused on the better-known green and
black teas, white and oolong also bring benefits to the table.
1. Tea can improve exercise endurance.
Scientists have found that the catechins (antioxidants) in green tea extract
increase the body’s ability to burn fat as fuel, which accounts for improved
muscle endurance.
2. Drinking tea could help reduce the risk
of heart attack. Tea might also help protect against cardiovascular and
degenerative diseases.
3. The antioxidants in tea might help
protect against many types of cancers, including breast, colon, colorectal,
skin, lung, esophagus, stomach, small intestine, pancreas, liver, ovarian,
prostrate and oral cancers. But don’t rely solely on tea to keep a healthy body
— tea is not a miracle cure, after all. While some studies suggest that tea has
cancer-fighting benefits, the current research is mixed.
4. Tea helps fight free radicals. Tea is
high in oxygen radical absorbance capacity (“ORAC”), which is a fancy way of
saying that it helps destroy free radicals that can damage DNA in the body.
While our bodies are designed to fight free radicals on their own, they’re not
100% effective —damage from these radicals has been linked to cancer, heart
disease, and neurological degeneration.
5. Tea is hydrating to the body, despite the
caffeine!
6. Drinking tea is linked with a lower risk
of Parkinson’s disease. When considered with other factors like smoking,
physical activity, age, and body mass index, regular tea drinking was
associated with a lowered risk of Parkinson’s disease in both men and women.
7. Tea might provide protection from
ultraviolet rays. We know it’s important to limit exposure to UV rays. The good
news is that green tea may act as a back-up sunscreen.
8. Tea could keep waist circumference in
check. In one study, participants who regularly consumed hot tea had lower
waist circumference and lower BMI than non-consuming participants. Scientists
speculate that regular tea drinking lowers the risk of metabolic syndrome,
which increases the risk of diabetes, artery disease and stroke. Although it’s
important to remember that correlation does not equal causation.
9. Regular tea drinking might also
counteract some of the negative effects of smoking and might even lessen the
risk of lung cancer. Good news, obviously, but not a justification for smoking.
10. Tea could be beneficial to people with Type
2 diabetes. Studies suggest that compounds in green tea could help diabetics
better process glucose.
11. Tea can help the body recover from
radiation. One study found that tea helped protect against cellular
degeneration upon exposure to radiation, while another found that tea can help
skin bounce back following exposure.
12. Green tea has been found to improve bone
mineral density and strength.
13. Tea might be an effective agent in the
prevention and treatment of neurological diseases, especially degenerative
diseases like Alzheimer’s. While many factors influence brain health,
polyphenols in green tea may help maintain the parts of the brain that regulate
learning and memory.
