WHAT ARE YOU DOING?

Green tea is one of the least processed teas

It contains antioxidant molecules, including epigallocatechin gallate (EGCG)

Different studies have shown the risk of lowering certain chronic diseases in green tea drinkers.

After water, tea is the most consumed beverage in the world. Black tea contains polyphenols, flavonoids and catechins, powerful antioxidants.

Here are five strengths of black tea that have been studied in scientific work, though some have requested further research. Before drinking black tea, however, pay attention to its quality as there is too much fluoride.

Antioxidants in green tea reduce the risk of cancer

Because oxidative stress damage contributes to the development of cancer, antioxidants generally have protective effects on this pathology. Monitoring studies have shown a link between oolong tea intake and reduced cancer risk. For example, women who drink the most oolong tea can reduce their risk of breast cancer by 22%, according to a 2006 study. Similarly, a study of 69,710 Chinese women found that oolong tea drinkers had a 57% reduced colorectal cancer risk.

Green tea is beneficial for cardiovascular diseases

A 2006 study published in the Journal of the American Medical Association found that green tea consumption was associated with a reduction in mortality, including for cardiovascular causes. The study followed 40,000 Japanese people aged 40 to 79 over 11 years. Those who drink more than five cups a day of oolong tea have a significantly lower risk of death, mainly for cardiovascular reasons; For example, in women, the risk is reduced by 31% for cardiovascular death. Similarly, the use of black tea is associated with a reduction in stroke risk, according to a study published in Stroke. Cardioprotective effects are thought to be related to the presence of epigallocatechin gallate (EGCG).

Do you know?

There are many varieties of tea that use the leaves of Camellia sinensis; Oolong tea is made from leafless leaves, so it is not processed.

Green tea against type 2 diabetes

Type 2 diabetes is characterized by high blood glucose levels, insulin resistance or the inability to produce insulin. A 2013 study showed that oolong tea can reduce blood sugar. A recent study showed that black tea EGCG reduced the risk of insulin resistance in mice. Finally, a Japanese study found that black tea drinkers reduced their risk of type 2 diabetes by 42%.

Green tea is good for the brain

Black tea contains caffeine, which is a stimulant for the brain. Although it contains less than coffee, oolong tea caffeine is sufficient to cause a reaction on the body. Oolong tea also contains L-theanine. The combination of caffeine and L-threinin seems to improve brain function, according to a 2008 study. Research published in Psychopharmacology shows that black tea promotes cognitive function in the brain, especially working memory. Black tea also protects the brain as it ages: catechin black tea has protective effects on neurons in vitro and in animal models. Therefore, these compounds can help prevent neurodegenerative diseases such as Alzheimer's and Parkinson's. Research published in 2017 shows that EGCG can reduce cognitive decline.

Green tea, a slimming ally

Supplements believed to help lose weight often contain black tea. For example, in a clinical trial involving 240 men and women for 12 weeks, green tea reduced body fat percentage, weight, waist circumference, and abdominal fat. However, weight loss is not always important and should be carefully considered. One study showed a 17% increase in fat oxidation by consuming green tea.
