Top 5 Benefits Of Green Tea For Health
Green tea is one of the maximum famous liquids in the world and for suitable reasons. It has been consumed for centuries in Asia for its refreshing taste and health benefits. But what exactly are the benefits of green tea and how does it work? In this article, we will explore the top 5 benefits of green tea for health, backed by scientific evidence.
Green tea contains powerful antioxidants:
One of the main reasons why green tea is so beneficial for health is because it contains a high amount of antioxidants, especially a type of polyphenol called catechins. Antioxidants are substances that can protect the cells from damage caused by free radicals, which are unstable molecules that can cause oxidative stress and inflammation in the body. Oxidative stress and inflammation are linked to many chronic diseases, such as cancer, diabetes, heart disease, and aging.
The most abundant and potent catechin in green tea is epigallocatechin-3-gallate (EGCG), which has been shown to have anti-inflammatory, anti-cancer, anti-diabetic, and anti-obesity effects in various studies. EGCG can also modulate the activity of different enzymes, hormones, and genes that are involved in various metabolic pathways.
Green tea may improve cognitive function:
Another benefit of green tea is that it may enhance cognitive function, mood, and brain health. This is incomplete due to the caffeine content of green tea, which can stimulate the central nervous system and ameliorate alertness, attention, memory, and response time. still, green tea also contains another emulsion called L- theanine, which is an amino acid that can cross the blood-brain hedge and have a comforting effect on the brain. L- theanine can also increase the situations of dopamine, serotonin, and gamma-aminobutyric acid( GABA) in the brain, which are neurotransmitters that regulate mood, emotion, and cognition.
The combination of caffeine and L- theanine in green tea may have a synergistic effect on cognitive function, as they can balance each other’s goods and reduce the implicit side goods of caffeine, similar to edginess, anxiety, and wakefulness. A 2017 review of 21 studies set up that drinking green tea may profit cognition, mood, and brain function in healthy grown-ups. A recent report likewise recommended that green tea utilization is related to a 64 lower danger of mental weakness in center endlessly matured adults.
Green tea may help with weight loss:
Green tea may also help with weight loss by increasing energy expenditure and fat oxidation. This means that green tea can boost metabolism and help the body burn more calories and fat. This effect is mainly attributed to the catechins and caffeine in green tea, which can stimulate the sympathetic nervous system and activate thermogenesis (heat production) and lipolysis (fat breakdown) in the body.
A 2022 review of 15 studies found that green tea consumption can increase energy expenditure by about 4% and fat oxidation by about 16%, compared to placebo. However, the effect of green tea on weight loss may vary depending on individual factors, such as genetics, diet, and lifestyle. The review also found that the ability of green tea to enhance weight loss is improved when combined with aerobic or resistance exercise.
Green tea may lower the risk of some cancers:
Cancer is one of the leading causes of death worldwide, and it is influenced by many factors, such as genetics, environment, and lifestyle. Green tea may have a protective effect against some types of cancer by modulating various molecular pathways that are involved in tumor initiation, growth, and metastasis. Some of these pathways include inflammation, angiogenesis (blood vessel formation), apoptosis (cell death), cell cycle regulation, and DNA repair.
While the evidence is mixed and inconsistent, some studies have suggested that drinking green tea may reduce the risk of developing certain cancers, such as lung cancer, ovarian cancer, breast cancer, colorectal cancer, esophageal cancer, prostate cancer, and skin cancer. However, more high-quality human studies are needed to confirm these findings and determine the optimal dose and duration of green tea consumption for cancer prevention.
Green tea may protect the brain from aging:
Green tea may also have a beneficial effect on the brain in the long term, by protecting it from aging and neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease. These diseases are characterized by the accumulation of abnormal protein aggregates in the brain, such as amyloid-beta and alpha-synuclein, which can impair the function and survival of neurons. Green tea may prevent or delay the formation of these protein aggregates by inhibiting their aggregation and promoting their clearance.
A 2020 study showed that green tea consumption is associated with lower levels of amyloid-beta in the cerebrospinal fluid of healthy adults, which may indicate a lower risk of Alzheimer’s disease. Another 2020 study showed that green tea extract can improve cognitive function and reduce the levels of alpha-synuclein in the blood of patients with Parkinson’s disease.
Green tea is a delicious and healthy beverage that can provide many benefits for health. It contains antioxidants, caffeine, and L-theanine, which can improve cognitive function, mood, metabolism, weight loss, cancer prevention, and brain health. However, it is important to drink green tea in moderation, as too much caffeine can cause adverse effects, such as insomnia, anxiety, and palpitations. It is also advisable to consult with a doctor before drinking green tea if you have any medical conditions or take any medications that may interact with it.
