• What are the benefits of white tea?

• During its production, green tea benefits from a processing technique that causes little or no oxidation. This makes it the preferred tea to make the most of the virtues of this plant.

  Green tea is packed with good-for-you antioxidants that can keep you fit in the long run. It is a way to help improve brain function, promote fat absorption or fight certain diseases.

  The polyphenols found in green tea not only reduce the risk of cardiovascular disease by lowering HDL ("good cholesterol") and LDL ("bad cholesterol") cholesterol but may also reduce the risk of cancer.

  Thus, green tea is considered one of the healthiest beverages on the planet, since it is more than just a hydrating drink thanks to its polyphenol content.

• Green tea has anti-anxiety effects.

  Green tea contains a range of healthy compounds. Rich in polyphenols, green tea contains a catechin called epigallocatechin-3-gallate or EGCG. Catechins are natural antioxidants that help prevent cell damage and provide other benefits that are regularly confirmed by research.

  Indeed, these substances can reduce the formation of free radicals [9] in the body, protecting cells and molecules from damage.

  These free radicals play a role in aging and many types of diseases. It should also be noted that green tea contains small amounts of minerals that can be beneficial to health.

  On the other hand, the key and stimulating active ingredient in tea is caffeine. However, it does not contain as much as coffee, but enough to produce a positive response without causing a "booster" effect and nervousness - which are usually associated with excessive caffeine consumption. Caffeine affects the brain by blocking an inhibitory neurotransmitter called adenosine. In this way, it increases the firing of neurons and the concentration of neurotransmitters such as dopamine and norepinephrine.

  Nevertheless, caffeine is not the only stimulant compound in green tea. It also contains an amino acid, "L-theanine," which can cross the blood-brain barrier [10]. L-theanine increases dopamine and alpha wave production in the brain and the activity of the inhibitory neurotransmitter GABA [11], which has anti-anxiety effects.

  The synergy of caffeine and L-theanine can therefore have particularly powerful effects on improving brain function.

  It should be noted that the effects of green tea on the brain also help protect the brain against aging, and neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

• Helps prevent cancer

  Cancer is caused by uncontrolled cell growth. It is one of the leading causes of death in the world.

  Research has shown that oxidative damage can lead to chronic inflammation, which can lead to chronic diseases like cancers. Antioxidants can help protect against oxidative damage.

  This is because research has linked the compounds in green tea to a reduced risk of cancer.

  For example, studies have found that women who drank the most green tea had about a 20% lower risk of developing breast cancer. [12]

  Other studies confirm that men who drank green tea had a lower risk of prostate cancer.

  Finally, studies have shown that those who drank green tea were about 40% less likely to develop colorectal cancer.

  Which green tea to lose weight or maintain a healthy weight?

  Green tea helps burn fat.

  

  
  

  Among the benefits, green tea (organic tea in particular) can also boost metabolic rate and increase fat burning in the short term, making it an ideal beverage to complement a healthy diet.

  This is because according to research, green tea and green tea extract can increase fat burning and increase metabolic rate.

  However, some studies on green tea do not show any increase in metabolism, so the effects may depend on the individual, and also on how the studies are organized.

  It is known that caffeine can also improve exercise performance by mobilizing fatty acids from adipose tissue and making them available for use as energy.

  Since green tea can increase metabolic rate in the short term, it makes sense that it can help with weight loss. Studies show that green tea can help reduce body fat [13], especially in the abdominal area.

  Green tea may help prevent type 2 diabetes.

  

  
  

  According to the WHO[14],"the number of people with diabetes has increased from 108 million in 1980 to 422 million in 2014".

  Type 2 diabetes is a real scourge and involves high blood sugar levels, which can be caused by insulin resistance or an inability to produce insulin.

  Studies [15] show that green tea can improve insulin sensitivity and reduce blood sugar levels.

  According to researchers, green tea consumption is associated with a reduced risk of type 2 diabetes for people who consume quality green tea daily.

  Green tea to prevent cardiovascular disease

  Cardiovascular disease (CVD), including heart disease and stroke, is the leading cause of death worldwide.

  CVD includes several disorders affecting the heart and blood vessels, such as high blood pressure, coronary heart disease, and heart failure.

  According to the WHO [16], "it is estimated that in 2012, 17.5 million people died from it, or 30% of all deaths worldwide. An estimated 7.5 million of these deaths are due to coronary heart disease and 6.7 million to stroke. Low- and middle-income countries are disproportionately affected, accounting for more than 80% of CVD deaths, affecting men and women almost equally. »

  Studies [17] show that green tea may improve some of the main risk factors for these diseases, including improved cholesterol levels (HDL, LDL). Thus, green tea increases the antioxidant capacity of theblood, which protects against heart disease.
