Properties of green tea

Green tea has stimulating properties thanks to caffeine. It is anti-inflammatory, anti-tumor, antioxidant and anti-aging. It is an antimicrobial (Staphylococcus epidermidis, Micrococcus luteus, Brevibacterium linens, Pseudomonas fluorescens, Bacillus subtilis), an antibacterial against "Staphylococcus aureus" resistant to methicillin by production of beta-lactamase. Apigenin derivatives (isoschaftoside and vicenin-3) are lipoxygenase inhibitors. Polyphenols are antioxidants and free radical scavengers. Catechins protect DNA and amino acids from nitrative stress (preferably in green tea), reduce total cholesterol and LDL-cholesterol. Flavonoids (quercetin) inhibit the oxidation of LDL, which induces atherogenesis.

Tea consumption is associated with a reduction in heart attacks, and a reduced risk of cancer, cognitive decline and dementia, as well as an improvement in bone density. Anticholinesterase activity is noted.
The astringency of tannins induces a decrease in the absorption and bioavailability of certain drugs (alkaloids, neuroleptics and antidepressants). Synergistic antimicrobial activity with penicillins is also observed.
L-theanine easily crosses the blood-brain barrier, increases brain levels of GABA, (an inhibitory neurotransmitter), and increases brain levels of dopamine and serotonin.
L-theanine therefore protects the brain from glutamate-induced neurotoxicity (cause of neurodegenerative diseases). It significantly reduces the mental, physical and social symptoms associated with premenstrual syndrome. It normalizes blood pressure, and helps to temper the irritating effects of caffeine.

Tea consumption increases telomere length and improves longevity.
Ingestion of green tea improves insulin sensitivity, decreases glycated hemoglobin, increases expression of GLUT-IV glucose transporters, improves glucose tolerance, and decreases incidence of diabetes.
Consumption of tea rich in catechins combats insulin resistance in overweight patients with metabolic syndrome. It acts on the distribution of body fat and, by increasing the combustion of lipids, participates in the regulation of weight.
Coffee and tea are the main sources of antioxidants in France, in the form of polyphenols which contribute 48.5% of total antioxidant intake.

Indications and uses of green tea

Essentially a pleasure drink, a 200 ml cup of tea provides an average of 135 mg of flavonoids. It is recommended for diabetes, obesity and Alzheimer's disease.
Green tea is rich in catechins, black tea especially in theaflavins and thearubigins (polymerized catechins), but both are rich in theanine.

Contraindications with green tea

- Decreased absorption and bioavailability of certain drugs (alkaloids, neuroleptics and antidepressants) by tannins

- Tea infusion inhibits the absorption of iron; the inhibition of non-heme iron absorption is 30% with green tea and varies from 36 to 61% with black tea. The iron absorption inhibiting effect of tea is attributed to the insoluble tannin-iron complex that forms in the lumen of the gastrointestinal tract.
