Benefits of Drinking Tea
Enjoy your tea.
It is good for health. In India, tea drinking is a part of our culture, but many of us who are health conscious believe that tea and coffee usage can be actually harmful. Doctors say that moderation needs to be exercised as with everything. 2-3 cups a day is ok but higher consumption may not add much to your health but certainly to your weight.
Research states that while all tea is healthy to drink, green tea contains the highest level of polyphenols (flavonoids), which are known for their antioxidant activity.
Much of the focus of modern research is on the effects of three ingredients found in tea: Antioxidants (polyphenols), nutrients, and caffeine.
Antioxidants
Many of the health benefits of drinking tea come from the high levels of antioxidants called polyphenols or flavonoids. These compounds are most prevalent in green and white teas, but are also present in varying degrees in Oolongs and black teas. In the processing of black teas another antioxidant is formed – theaflavin. This is weaker than the polyphenols in Green teas, but still performs antioxidant activities in laboratory experiments. Polyphenols scavenge cell-damaging free radicals, which are linked with cancer-causing genes and cause LDL cholesterol to form artery-clogging plaque. The polyphenols in tea possess 20 to 30 times the antioxidant potency of vitamins C and E. Antioxidants impair the ability of free radical cells to harm the molecules that make up our bodies.
Nutrients
Tea is a dietary source of important vitamins and minerals. Tea contains Carotene, a precursor to vitamin A; Thiamin (vitamin B1); Riboflavin (vitamin B2); Nicotinic acid, Pantothenic acid, Ascorbic acid (vitamin C), vitamin B6; Folic acid; Manganese, Potassium, and Fluoride.
Caffeine
In moderation caffeine can be a benefit – stimulating the metabolism, increasing brain function and alertness. But too much coffee and caffeinated colas, can lead to caffeine overload. A cup of coffee has approximately 125-185 milligrams of caffeine.Black Teas have a range of about 45-60 milligrams of caffeine , 35-45 milligrams for Oolong teas, and 15-20 milligrams for green teas. Depending upon the type of tea and how it is prepared, caffeine levels can be significantly greater or lower.
Some black teas, depending on how it is brewed , can have as much caffeine as a cup of strong coffee. Because caffeine from tea does not take effect for 10-15 minutes, it provides more of a feeling of relaxed energy boost rather than the quick pick me up of a cup of coffee.
The effect of caffeine is also complemented by another compound found only in tea, theophylline. While caffeine primarily is active in the brain and muscles, theophylline is active in stimulating the respiratory system, heart and kidneys. Tea is helpful in maintaining a healthy cardiovascular system.
