The Benefits of Green Tea Explained!
Native to China and India, green tea has gained popularity for its role in improved heart health and conditions like Alzheimer’s disease and arthritis.Benefits of Green tea is also being hailed for the weight loss benefits it offers. Made from unoxidised tea leaves, green tea is less processed as compared to black tea, and as such, contains a greater amount of beneficial compounds.
Green tea has a positive impact on overall health owing to its nutritional content. Here are some benefits of green tea.
Regulates blood pressure
Blood pressure is caused by angiotensin-converting enzyme or ACE which is secreted by the kidneys. Drugs for blood pressure act as ACE inhibitors, preventing the action of ACE and helping lower blood pressure. Green tea is a natural ACE inhibitor and long-term intake of this beverage has been associated with improved blood pressure levels.
Improves heart health
As mentioned above, regular green tea consumption can lower risk of coronary heart disease. The beverage can also lower bad cholesterol levels that directly contribute to heart disease while not affecting the good cholesterol. Green tea has been shown to increase the antioxidant capacity of blood, thus protecting the heart from reactive oxygen species and preventing heart attacks.
Lowers risk of diabetes
Diabetics lose sensitivity to insulin, the hormone that keeps blood sugar levels in control, due to which insulin is less effective in signalling cells to absorb sugar from the blood. This results in both higher and lower blood sugar levels. Green tea is known to sensitise cells so that they can metabolise sugar better, thus improving diabetes symptoms.
Boosts brain function and protects brain
The key ingredient in green tea, caffeine, not only keeps you awake but also makes you smarter. This stimulant isn’t found in as much concentration in green tea as in coffee, but the contents can produce a response without causing jittery effects that come from consuming too much caffeine. Caffeine blocks the inhibitory neurotransmitter adenosine in the brain. This increases the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine. According to studies, caffeine can improve various aspects of brain function like mood, memory, vigilance, and reaction time.
Reduces Risk of Cancer
Green tea is known to be effective against a range of cancers including those of the lung, skin, prostate, breast, colon, liver, and pancreas by preventing cancer cell proliferation and accelerating recovery. According to studies, EGCG can kill cancer cells without affecting healthy ones; drinking about four cups of green tea each day can aid cancer treatment.
Aids weight loss efforts
Caffeine acts as a stimulant and has been shown to boost fat burning and improve exercise performance. Green tea is hailed the world over for its weight loss benefits.
Promotes dental health
Studies show green tea catechins are capable of inhibiting the growth of Streptococcus mutans, the main harmful bacteria in the mouth which causes plaque formation and contributes to cavities and tooth decay.
Offers antibacterial properties
Catechins in green tea have biological effects – they can kill bacteria and inhibit viruses, lowering the risk of infections. Green tea catechins boost immune function by protecting against oxidants and free radicals. EGCG found in green tea can increase the number of regulatory T cells which are important for immune function and suppressing autoimmune diseases.
Relieves pain and inflammation
Antioxidant effects of EGCG limit the production of certain molecules in the body that can otherwise cause pain and inflammation, as in arthritis. Green tea not only improves health of bones and cartilage but has been found to be 100 times more effective than vitamins C and E in offering antioxidant benefits.
