Top 10 proven Benefits of Green Tea

Green tea is one of the most commonly consumed teas in the world.

Green tea extract is its concentrated form, with just one capsule containing the same amount of active ingredients as an average cup of green tea.

1) Green tea and cancer prevention:

According to the National Cancer Institute, the polyphenols in tea have been shown to decrease tumor growth in laboratory and animal studies and may protect against damage caused by ultraviolet UVB radiation.

In countries where green tea consumption is high, cancer rates tend to be lower, but it is impossible to know for sure whether it is the green tea that prevents cancer in these particular populations or other lifestyle factors.

Some studies have also shown the positive impacts of green tea on the following types of cancer:

  • Breast
  • Bladder
  • Ovarian
  • Colorectal (bowel)
  • Esophageal (throat)
  • Lung
  • Prostate
  • Skin
  • Stomach

Researchers believe that it is the high level of polyphenols in tea that helps kill cancerous cells and stop them from growing. However, the exact mechanisms by which tea interacts with cancerous cells is unknown.

2) High in Antioxidants

The health benefits of green tea extract are mostly due to its high antioxidant content.

Antioxidants can help reduce oxidative stress by fighting cell damage caused by free radicals. This cell damage is associated with aging and several diseases.

However, other studies have not found that tea can reduce cancer risk. The amount of tea required for cancer-preventive effects also varies widely in studies – from 2-10 cups per day.

3) Green tea heart benefits

A 2006 study published in the Journal of the American Medical Association concluded that green tea consumption is associated with reduced mortality due to all causes, including cardiovascular disease.

4) Green tea and lower cholesterol

An analysis of published studies in 2011 found that consuming green tea, either as a beverage or in capsule form, was linked to significant but modest reductions in total and LDL or “bad” cholesterol.

5) Stroke risk and green tea

Drinking green tea or coffee on a regular basis is associated with a reduced risk of stroke, according to a study published in the journal Stroke: Journal of the American Heart Association.

6) Green tea for type 2 diabetes

Studies concerning the relationship between green tea and diabetes have been inconsistent. Some have shown a lower risk of developing type 2 diabetes for green tea drinkers than for those who consumed no tea, while other studies have found no association between tea consumption and diabetes at all.

7) Green tea and weight loss

Green tea may promote a small, non-significant weight loss in overweight and obese adults; however, since weight loss in the studies was so minimal, it is unlikely that green tea is clinically important for weight loss.

8) Good for the Brain

The antioxidants in green tea extract, especially EGCG, have been shown to protect brain cells from oxidative stress.

This protection can help reduce brain damage that could lead to mental decline and brain diseases like Parkinson’s, Alzheimer’s and dementia.

9) Green tea and inflammatory skin diseases

A 2007 study concluded that green tea could hold promise as a new treatment for skin disorders such as psoriasis and dandruff. Researchers studied an animal model for inflammatory skin diseases, often characterised by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells’ life cycles.

10) Green tea and Alzheimer’s

In a study published in 2011, researchers tested the effect of a component of green tea, CAGTE (or “colon available” green tea extract), after it had been digested, to see how it affected a key protein in Alzheimer’s disease.
