On the occasion of International Tea Day, Nutrimuscle explains why you should incorporate this ancient drink into your daily diet. Appreciated for both its health effects and its applications in sports, green tea has many recognized virtues.
A drink with global impact
The second most consumed drink in the world after water, tea has accompanied humanity for millennia. Originating in Asia, it is now present on all continents and plays a major economic role in many producing regions.
Global demand continues to increase, particularly in Western countries. This growth requires particular attention to agricultural practices, in order to preserve soil quality, biodiversity, and the sustainability of tea cultivation.
What is green tea?
There are several main families of tea: green, black, white, oolong, as well as rarer varieties such as yellow or purple tea. All come from the same plant, Camellia sinensis, but differ in their processing method.
Green tea is distinguished by the absence of fermentation and oxidation. This process allows it to retain a high concentration of catechins, particularly polyphenols, known for their antioxidant properties. It also contains less theine than black tea, which makes it milder for the nervous system.
To preserve its nutrients, green tea should be steeped briefly, ideally between 50 and 75 °C for a maximum of two minutes. Water that is too hot or prolonged steeping degrades its vitamins and antioxidants.
The health benefits of green tea
Green tea is known for its richness in antioxidants, particularly epigallocatechin gallate (EGCG). These compounds help neutralize free radicals responsible for oxidative stress and cellular aging.
Scientific studies have also highlighted a link between regular green tea consumption and a reduced risk of certain cancers, notably prostate and breast cancer. Polyphenols act selectively: they protect healthy cells while disrupting the metabolism of cancer cells.
Consumed as part of a balanced diet and good lifestyle habits, green tea also contributes to the proper functioning of the cardiovascular system and supports the body's natural defenses.
The benefits of green tea for sports
For athletes, green tea is often used to support a phase of fat loss or cutting. The catechins it contains stimulate thermogenesis, which increases energy expenditure and promotes fat oxidation.
Green tea also acts on the regulation of insulin, a key hormone in fat storage, and limits the development of fat cells. Combined with regular physical activity, it allows the body to prioritize the use of lipids as an energy source.
Studies have shown a measurable increase in caloric expenditure and the energetic contribution of fats in athletes who consumed catechins daily over several weeks.
In summary, green tea is a beverage with multiple benefits, both for general health and for performance and body composition. Integrated into a varied and balanced diet, it is a natural and sustainable ally, provided that appropriate preparation methods are respected.
