Tea and its benefits
Tea is recognized worldwide for its many benefits, here is an overview:
The strong presence of catechins and thearubigins (polyphenols) gives it antioxidant properties therefore having a positive impact on skin cells to fight against skin aging. The polyphenol content varies according to several criteria such as the climate, the type of tea, the season, the freshness of the leaves, the brewing time ... Green tea is the tea that contains the greatest amount of polyphenols.
It is thanks to theine that tea acts as a stimulant and helps soften the walls of blood vessels. It fights against the hardening of the arteries (arteriosclerosis). According to a study by Harvard researchers, people who consume at least 1 cup of tea per day have 40% less cardiovascular risk than those who do not. The antioxidants in tea have the ability to limit the formation of atheromatous plaque which leads to clogging of the arteries.
Medical researchers believe that green tea acts on the lining of blood vessels. This helps them stay more flexible and better resist changes in blood pressure. In addition, tea could prevent blood clotting, the main cause of heart attacks.
In medicine, we distinguish between good cholesterol (HDL) and bad cholesterol (LDL). Green tea reduces bad cholesterol. In addition, it improves the good cholesterol / bad cholesterol ratio.
Some studies show better prevention and better management of Alzheimer's disease thanks to tea. It is in particular EGCG, a rich polyphenol contained in green tea, which will protect the brain against neurodegenerative diseases.
Also according to these studies, Green tea will promote proper functioning of neurons, and help repair damaged brain cells.
Its well-known diuretic effect is not the only action of green tea against weight.
Thanks to its proportion of catechins which acts as a fat burner, tea and particularly green tea is a good slimming ally.
The caffeine in tea has a fat burning role in the body. The high level of catechins and epigallocatechins also acts on the distribution of fat in the body, especially in the abdomen. Be careful, however, tea alone does not significantly lose weight (it should be accompanied by healthy meals and regular physical activity).
According to a study by Korean researchers, green tea helps improve acne, as EGCG has the ability to reduce sebum production and reduce inflammation. The molecule also reduces the viability of the bacteria that cause acne.
- Cancer risk reduction:
Drinking green tea would also potentially reduce the risk of cancer (especially colorectal, bladder & prostate). Once again, it is the catechins present in large quantities that have an activity on cancer cells (during different stages of their development). When cancer cells proliferate, they must form a parallel network of blood vessels in order to be nourished and be able to multiply. EGCG has the ability to prevent this phenomenon of angiogenesis. Studies have shown that women who consume green tea daily reduce the risk of breast cancer by 22% and the risk of colorectal cancer by 57%.
Green tea could help control diabetes. One of its benefits is to function as a regulator of our glucose levels after meals. In this way, it prevents insulin spikes and fat build-up.
Drinking green tea regularly would reduce the risk of blood pressure.
- Transit :
Tea is a great ally, it inhibits toxins and bad bacteria and helps keep good bacteria called probiotics intact.
- Viral disease:
In winter, tea consumption fights the flu. Theaflavin (the most oxidized form of catechin present in particular in black tea) is able to neutralize the influenza virus and thus render it inactive. This is because the antioxidant activity of polyphenols inhibits the virus. Catechin also has antiviral and antibiotic properties, which makes green tea a very effective treatment. Indeed, research indicates that green tea slows the spread of many diseases.
- Mood :
Thanks to its caffeine content, although low compared to coffee, allows you to stay vigilant. In addition to improving mood, it promotes cognitive function by stimulating alertness and attention. Drinking tea in the morning for breakfast helps to start the day well.
Theanine, the amino acid contained in tea, is a substance that has a restful and tranquilizing effect: one more advantage therefore for tea consumers.
Tea, and especially green tea, is an excellent oral ally.
Its richness in polyphenols strengthens tooth enamel and helps reduce the risk of cavities, bad breath and diseases that can affect teeth and gums.
be careful, tea also contains tannin. Tannin can reduce the absorption of iron and folic acid, so consuming green tea is not suitable for people with iron deficiency or high iron requirements such as pregnant women.
In addition, its antioxidant action could impact certain treatments and it may be inadvisable in certain cases of chemo or radiotherapy.
