Today we are going to try to answer this question: what is the best herbal tea? Let’s get started!
Well, it’s just one of the most known drink in the world: the green tea, of course! Even though we believe that we know everything about it, the green tea still continue to surprise us! In appearance, it looks like nothing and yet it ‘s stuffed with powerful substances.
Its antioxidants and anti-cancer properties are already famous ( especially against breast cancer) and it’s getting better: green tea is a great solution to lose weight, gain stamina and increase your energy level!
Let’s go into the details of this topic, shall we?
What do we really know about tea?
Nowadays, tea is the most consumed drink in the world after water. Green tea accounts for 18% of world tea consumption and black tea 80%.
But there is a huge misunderstanding about tea. When we talk about green tea, white tea, and black tea, most of us imagine different species of trees whose leaf ‘s color varies between light green and dark green…
In reality, it’s completely different!
All the different types of tea ( around 3200) come from the same tree, the tea tree, also known as “camellia of China” ( in Latin Camelia Sinensis ).
Several factors will influence the fragrance of the tea:
- season of harvest (summer, fall, winter, and spring) and especially the treatment that follows the harvest.
The treatment is one of the main keys that makes all the difference on the final taste of the tea ( drying, roasting, leaf withering, oxidation, flavoring, manufacturing secrets… you name it!)
In the end, you get an infinite panel of varieties, especially if you compare two green tea!
One of the most precious beverage: the green tea!
Of all the teas, green tea is the most popular for its therapeutic virtues. The treatment of leaves is what makes the difference between tea varieties. In comparison to the black tea and the white tea, the green tea has the least treatment which allows preserving as much as possible its properties, its active substance, and its effectiveness.
Green tea is not just a brew… It carries a large number of polyphenols, such as flavonoids and catechins, mainly epigallocatechin gallate ( EGCG ) which is an antioxidant, antiangiogenic and anti-tumor agent.
But there is more, let’s look at the component list of the green tea:
- Green tea is rich in vitamin C, which is also a great antioxidant.
- It contains also caffeine and other vitamins like A, B, B2, K, and PP.
- There are some manganese and selenium to prevent damage from free radical.
- Zinc to improve neurological functions
- Magnesium to improve our energy level
For information, a dry green tea leaf contains between 0.5% and 10% of caffeine and between 15% and 30% of catachins, of which 50% and 75% on average of EGCG.
Burn calories and gain stamina!
Two researchers from the University of Basel in Switzerland have carried out an extensive synthesis of all in vitro and in vivo studies (human and animal ) on EGCG of green tea. The majority of studies show that green tea and green tea extracts are effective at losing weight, controlling blood sugar levels, and reducing the risk of overweight cardiovascular disease.
Green tea is also known to accelerate the use of fat during sports practice and improve cardiac capacity and endurance. In one study, 10 healthy men consumed green tea and saw their energy expenditure increased by 4%.
Green tea causes the body to burn fat especially. Another study showed that fat oxidation increased by 17% in subjects who had consumed green tea.
Several studies have shown that green tea helps to lose weight, especially in the belly.
It should be noted that the subjects lost more weight when they practiced sport in parallel with the green tea cure.
In a large 12 week study of 240 subjects in both sexes, it was found that green tea significantly reduced fat mass, waist circumference, and abdominal overweight.
Of course, it does not work for everyone. Some studies have found no acceleration of metabolism after green tea consumption. It all depends on the initial consumption: with people who already consume a lot of green tea or coffee, an additional dose of green tea has a little effect on weight, but for others, the effect is really clear.
The caffeine of green tea is also known to improve physical performance ( + 12% according to a synthesis of British studies ). It is useful to be more successful in sport, improve endurance, or simply be more active throughout the day.
Caffeine works by mobilizing fatty acids to make them available as a direct source of energy in endurance efforts, and by making muscles more responsive to contractions, which directly increases strength in sports explosives ( bodybuilding, rugby, etc…).
EGCG has been shown to be effective in improving cardiac capacity and endurance. In a double-blind, placebo-controlled study, US researchers found that EGCG increased VO2 max consumption without accelerating the heart rate. This suggests that EGCG can increase cardiac output: capillaries more efficiently recover oxygen from the blood to use it during sports practice.
Green tea is therefore recommended to burn more calories, lose fat and increase physical performance.
What can we expect from the amazing theanine?
Green tea is also rich in theanine, a substance that interests researchers. According to preliminary studies, theanine has a relaxing effect on the nervous system and a stimulating effect on the immune system. However, the data are still insufficient to confirm its effectiveness.
