What is green tea?
Green tea comes from the leaves of Camellia sinensis, like black tea but unlike it, it is not oxidized after harvest. This detail changes everything: the active compounds, notably polyphenols, are preserved in large quantities.
In terms of taste, there is not just one green tea, but dozens. Depending on the origin and the processing method, we can find vegetal, iodized, flowery or slightly sweet aromas. Enough to satisfy very different palates.
The main benefits of green tea
A formidable antioxidant
Green tea is particularly rich in catechins, including EGCG (epigallocatechin gallate), known for its effects on oxidative stress. Concretely, this means that you help your body to better fight against free radicals responsible, among other things, for premature aging. An asset for the skin, but also for health in general.
A boost for the line
Green tea is often mentioned in discussions around weight management, and it's no coincidence. It can slightly stimulate metabolism, promote fat oxidation and help regulate appetite. However, it does not work miracles alone: it will be much more effective integrated into a balanced diet and regular physical activity.
Concentration, without the jitters of coffee
This is one of its most appreciated assets. Green tea contains caffeine, but in moderate quantities, and especially L-theanine, an amino acid with relaxing effects. The result? Gentle mental stimulation, better concentration, and much less nervousness than with coffee. You remain alert, but calm.
An ally for the heart
Studies suggest that regular consumption of green tea is associated with better cardiovascular health: reduction of bad cholesterol, improvement of blood circulation, reduction of certain cardiac risks. A simple gesture, but potentially lasting.
A natural digestive
In Asia, it is common to drink a green tea after meals. And for good reason: it facilitates digestion, reduces bloating and provides a feeling of lightness. A very good habit to adopt after a hearty lunch.
A blood sugar regulator
Green tea may also play a role in regulating blood sugar levels. Some studies suggest that its active compounds, notably catechins, help improve insulin sensitivity and slow the absorption of sugars into the blood. For people prone to glycemic fluctuations, incorporating it regularly into their diet can be an interesting habit without replacing appropriate medical monitoring.

Which variety to choose?
Japanese green teas are often the most intense. Sencha, fresh and vegetal, is perfect for everyday use. The Matcha, in powder, is particularly concentrated in antioxidants. Genmaicha, mixed with toasted rice, offers more delicious and rounded notes.
The chinese green teas are generally milder and slightly sweet. Long Jing (Dragon Well) is subtle and elegant, while Gunpowder, more robust, is often used to prepare mint tea. Ideal if you're just starting out.
The flavored blends, finally, allow you to combine taste pleasure and benefits: citrus fruits, red fruits, flowers the offer is wide and the tea houses compete in creativity.
How to prepare it well?
Boiling water is the enemy of green tea: it destroys the aromas and some of the nutrients. The ideal temperature is between 70 and 80°C. For the infusion time, 2 to 3 minutes is enough, otherwise your tea risks becoming bitter.
Regarding the time of day, in the morning it accompanies a gentle awakening, during the day it helps to stay focused, and after meals it promotes digestion. If you are sensitive to caffeine, avoid drinking it in the evening.
Green tea, also in your beauty treatments
Its properties don't stop at the cup. Thanks to its antioxidants, green tea is a popular ingredient in cosmetics : it is found in many treatments to help fight against skin aging, soothe inflammation and improve the radiance of the complexion. Some also use it as a hair rinse for shinier hair and a soothed scalp.
