What are antioxidants & How it benefits health?

Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures. The sources of antioxidants can be natural or artificial.

Free radicals are waste substances produced by cells as the body processes food and reacts to the environment. If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function. Factors that increase the production of free radicals in the body can be internal, such as inflammation, or external, for example, pollution, UV exposure, and cigarette smoke.

Oxidative stress has been linked to heart disease, cancer, arthritis, stroke, respiratory diseases, immune deficiency, emphysema, Parkinson’s disease, and other inflammatory or ischemic conditions. Antioxidants are said to help neutralize free radicals in our bodies, and this is thought to boost overall health, according to Medical News Today.

Green tea - A rich source of antioxidants

Green tea is arguably one of the most famous superfoods out there, but how much do you know about what’s in your cup?

Unlike black and oolong (wulong) teas, though, green tea is less processed. 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 (NCCIH), green tea has been used in Chinese and Japanese medicine practices for centuries.

Unlike other types of tea, green tea contains high levels of compounds called catechins. The most notable catechin is epigallocatechin-3-gallate (EGCG), according to Everyday Health.

EGCG is probably best known for its role as the major active compound in green tea. In fact, the numerous health benefits associated with drinking green tea are typically credited to its EGCG content. Much of EGCG’s claim to fame comes from its strong antioxidant capacity and potential to reduce stress and inflammation.

As an antioxidant, EGCG protects your cells from damage associated with oxidative stress and suppresses the activity of pro-inflammatory chemicals produced in your body, such as tumor necrosis factor-alpha (TNF-alpha). Stress and inflammation are linked to a variety of chronic illnesses, including cancer, diabetes, and heart disease.

Thus, the anti-inflammatory and antioxidant effects of EGCG are thought to be one of the main reasons for its broad disease-preventing applications, according to Healthline.

Zero Degree Green Tea - Convenient bottled tea with high EGCG content

Zero Degree Green Tea by Tan Hiep Phat is among the best-sellers in the Vietnamese bottled soft drink market.

Zero Degree Green Tea is extracted from green tea leaves from Thai Nguyen highlands in the north of Vietnam where the climate is perfectly suited to cultivating the highest quality green tea. The technology used to make the drink, combined with an aseptic environment (sterile environment) in which the drink is filled and bottled, helps retain the natural flavor of the product and preserve the nutrients.

"Aseptic cold extraction technology in beverage production combines five aseptic factors: sterilized bottles, sterilized caps, sterilized water, sterilized product, aseptic extraction environment. The technology creates good flavor and maximum EGCG as the beverage is not cooked at a high temperature and contains preservatives and industrial colors," Tran Uyen Phuong, Tan Hiep Phat's Deputy CEO said.
