Green Tea Benefits For Weight Loss Caffeine Is It Good For You

Struggling with fatigue, low energy and poor mental focus? A cup of green tea might be exactly what you need to feel like yourself again. This natural beverage has been hailed for its health benefits for centuries. Loaded with antioxidants, it protects against heart disease, diabetes, weight gain and even cancer.

A January-April 2017 review published in the Journal of Oral and Maxillofacial Pathology discussed the potential benefits of green tea. As the researchers note, this drink is rich in catechins that reduce oxidative stress and inflammation, support cardiovascular health and inhibit the proliferation of cancer cells. Furthermore, it may help prevent digestive disorders, neurodegenerative diseases, high blood pressure and other ailments.

In addition to flavonoids and other antioxidants, green tea contains amino acids, caffeine, vitamins and minerals. One cup provides 50 to 100 milligrams of caffeine, as reported in the above review.

This natural stimulant is clinically proven to increase muscle strength and endurance, leading to enhanced exercise performance. It may also improve your mood and alertness, boost your cognitive skills and energize your body, according to a research paper published in the Ohio Journal of Science in May 2015.

Caffeine may have a wide range of effects on the body. It can help boost energy levels, improve alertness and concentration, increase athletic performance and improve mental health. It can also cause side effects such as insomnia, anxiety, nervousness and stomach upset if you consume too much caffeine.

Caffeine has also been shown to cause addiction, so you may want to stop consuming it because it may be difficult for you to stop drinking coffee or tea if youve become addicted to them.

Its important to note that caffeine can have negative effects on people who are sensitive to it, such as those who suffer from high blood pressure or people who have a sensitivity to chemicals such as medications or drugs such as antidepressants.

Green tea is made from the leaves of the Camellia sinesis plant, just like all other nonherbal teas. Unlike black and oolong teas, though, green tea is less processed, as its made using steam-dry methods. The delicate processing techniques are thought to be among the reasons why green tea is so rich in nutrients and antioxidants all of which may lead to a range of health benefits. In fact, according to the National Center for Complementary and Integrative Health , green tea has been used in Chinese and Japanese medicine practices for centuries.

While youve probably heard a lot of chatter about the benefits of green tea, the NCCIH points out that much of the evidence isnt conclusive, and more studies are needed. New York Citybased Megan Casper, RDN, owner of Megan Casper Nutrition, notes another key caveat: Many studies of green tea use green tea extract, which can be much stronger than your average at-home brew.

However, the solvent is also used in some nail varnish removers, paints as an activator, and to clean circuit boards.
