When should you drink green tea?

Many people will be surprised to learn when drinking green tea can affect their ability to reap benefits, or face the risk of some side effects if taken the wrong way.

Tea contains tannins, essential oils, vitamins, protid, minerals and pigments. In particular, this beverage contains caffeine, which stimulates the central nervous system, cardiovascular activity, kidney function and digestion.

This drink’s mind-boosting properties are partly attributed to caffeine, a stimulant proven to enhance attention and alertness. But unlike coffee and other caffeinated drinks, green tea also contains L-theanine, an amino acid that has a relaxing effect.

Research published in the US National Library of Medicine in 2008 found that L-theanine and caffeine work together to improve brain function and mood – without the negative side effects that can come with it. when absorbing caffeine alone. For the above reasons, we should enjoy this tea in the morning, before starting a new day, to get the best results.

Drinking green tea is also beneficial right before a workout. Research shows that consuming green tea extract before exercise increases fat burning by 17%. Another study on women showed that drinking 3 servings of green tea per day before exercise and another 2 hours before exercise increased fat burning.

Additionally, tea can speed up recovery after an intense workout.

There are many health benefits, but using this tea the wrong way can come with some downsides.

Prevents absorption of nutrients: Certain compounds in green tea can bind with minerals in the body and prevent their absorption. In particular, the compound tannin found in green tea acts as an anti-nutrient and reduces iron absorption.

Studies show that epigallocatechin-3-gallate (EGCG) in green tea can bind with minerals like iron, copper and chromium, preventing absorption in the body.

Other studies have also shown that drinking tea with meals can reduce iron absorption, which can lead to a deficiency over time. So it’s best to drink green tea between meals.

Causing some people to lose sleep: A 237 ml cup of green tea contains about 35 mg of caffeine. This is much less than the roughly 96 mg of caffeine in a cup of coffee, but it can still cause side effects in sensitive people.

Common side effects of excessive caffeine consumption include anxiety, high blood pressure, restlessness and nervousness. Caffeine can also disrupt sleep. Therefore, if you are sensitive to caffeine, consider avoiding drinking green tea 6 hours before bedtime, to avoid problems.
