Caffeine and Tea

Caffeine is a natural component of tea and is considered safe when consumed in moderation. According to Health Canada, a balanced diet can include a moderate intake of caffeine with daily recommended consumption limits of between 400 to 450 mg. This is equivalent to 10-12 cups of tea per day. Actual caffeine levels in tea are dependent upon the specific blends and strength of the tea brew, but most servings contain only 25 to 34 mg. Tea contains one third to one half less caffeine than coffee.

Flavonoids and Tea

Teas from the Camellia sinensis plant contain a group of compounds called flavonoids (polyphenols) which were originally studied because of their antioxidant properties, but are now known to have multiple, or pleotrophic effects in the body that go beyond antioxidant properties.  Antioxidants are compounds that neutralize the body’s naturally occurring but cell-damaging free radical molecules. Damage by free radicals over time is believed to contribute to the development of many chronic disease including cancer and cardiovascular disease. New research shows that flavonoids (polyphenols) in tea may also help ward off the sustained inflammatory process and vascular damage linked to chronic human conditions associated with aging including heart disease  and decline in memory and cognition.

Daily Healthy Beverage Guidelines

The proposed Daily Healthy Beverage Guidelines were developed by a panel of nutrition experts to help consumers make smart decisions about their beverage consumption. Published in the March 2006 issue of the Journal of American Clinical Nutrition, the Guidelines are based on the relative health and nutritional benefits and risks of various types of beverages.

Under the guidelines, women should drink nine eight-ounce servings of beverages a day and men should drink 13 servings. However no more than 10 to 15 percent of daily calorie intake should be consumed in beverages and caffeine consumption should be limited to 400 mg per daydecay and cavities, and reduce kidney stones.
