This article has been cited by other articles in PMC. Despite the wide range of methods available for measurement of hemoglobin, no single technique has emerged as the most appropriate and ideal for a blood donation setup. A prospective study utilizing blood samples was carried out in a blood donation setting for quality evaluation of four methods of hemoglobin estimation along with cost analysis:

Black tea contains much lower concentrations of these catechins than green tea 6. The extended oxidation of black tea increases the concentrations of thearubigins and theaflavins, two types of complex polyphenols 2. Oolong tea contains a mixture of simple polyphenols, such as catechins, and complex polyphenols 2.

White and green tea contain similar amounts of EGCG but different amounts of other polyphenols 7. Although iced and ready-to-drink teas are becoming popular worldwide, they may not have the same polyphenol content as an equal volume of brewed tea 8.

The polyphenol concentration of any particular tea beverage depends on the type of tea, the amount used, the brew time, and the temperature 3. The highest polyphenol concentration is found in brewed hot tea, less in instant preparations, and lower amounts in iced and ready-to-drink teas 3.

As the percentage of tea solids i. Ready-to-drink teas frequently have lower levels of tea solids and lower polyphenol contents because their base ingredient may not be brewed tea The addition of other liquids, such as juice, will further dilute the tea solids 9.

Decaffeination reduces the catechin content of teas Dietary supplements containing green tea extracts are also available 1. How might tea help prevent cancer? Tea polyphenols have also been shown to inhibit tumor cell proliferation and induce apoptosis in laboratory and animal studies 1 In other laboratory and animal studies, tea catechins have been shown to inhibit angiogenesis and tumor cell invasiveness In addition, tea polyphenols may protect against damage caused by ultraviolet UV B radiation 1315and they may modulate immune system function Furthermore, green teas have been shown to activate detoxification enzymes, such as glutathione S-transferase and quinone reductase, that may help protect against tumor development Although many of the potential beneficial effects of tea have been attributed to the strong antioxidant activity of tea polyphenols, the precise mechanism by which tea might help prevent cancer has not been established Are there safety considerations regarding tea consumption?

Tea as a food item is generally recognized as safe by the U. Food and Drug Administration. Safety studies have looked at the consumption of up to mg of EGCG in supplement form in healthy adults over 1- to 4-week time periods 17 The adverse effects reported in these studies included excess intestinal gas, nausea, heartburn, stomach ache, abdominal pain, dizziness, headache, and muscle pain 17 In a Japanese study, children aged 6 to 16 years consumed a green tea beverage containing mg catechins experimental group or 75 mg catechins control group for 24 weeks with no adverse effects The safety of higher doses of catechins in children is not known.

As with other caffeinated beverages, such as coffee and colas, the caffeine contained in many tea products could potentially cause adverse effects, including tachycardiapalpitations, insomniarestlessness, nervousness, tremors, headache, abdominal pain, nausea, vomiting, diarrhea, and diuresis However, there is little evidence of health risks for adults consuming moderate amounts of caffeine about to mg per day.

A review by Health Canada concluded that moderate caffeine intakes of up to mg per day equivalent to 6 mg per kilogram [kg] body weight were not associated with adverse effects in healthy adults The amount of caffeine present in tea varies by the type of tea; the caffeine content is higher in black teas, ranging from 64 to mg per 8 fl oz serving, followed by oolong tea, which contains about 29 to 53 mg per 8 fl oz serving 4.

Green and white teas contain slightly less caffeine, ranging from 24 to 39 mg per 8 fl oz serving and 32 to 37 mg per 8 fl oz serving, respectively Decaffeinated teas contain less than 12 mg caffeine per 8 fl oz serving Research on the effects of caffeine in children is limited In general, caffeine doses of less than 3.

Higher doses have resulted in some behavioral effects, such as increased nervousness or anxiety and sleep disturbances Aluminum, a neurotoxic elementis found in varying quantities in tea plants. The variations in aluminum content may be due to different soil conditions, different harvesting periods, and water quality 4.Get the latest news and analysis in the stock market today, including national and world stock market news, business news, financial news and more.
