One of the UK's leading diabetes web sites; diabetes.co.uk, has written several interesting tea articles linking tea consumption to a significant reduction in the risk of type 2 diabetes. One recent review cites a 2009 Dutch study that found that drinking 3 cups of tea per day lead to an astonishing 40% reduction in the risk of developing type 2 diabetes. The article goes on to suggest that tea can promote numerous health benefits to include.
- Improving insulin sensitivity
- Maintaining healthy blood pressure
- Preventing blood clots
- Reducing risk of cardiovascular disease
- Reducing risks of developing type 2 diabetes
- Reducing risks of developing cancer
It does, however, caution that an American study in 2002 found that the use of milk (which contains lactose, a type of sugar) decreased the insulin-sensitizing effects of tea. This is perhaps why so many people from Taiwan and Japan use whole leaf tea, often produced with mineral water.
The article wisely points out that various additional factors that help to prevent type 2 diabetes include:
- Eating minimal amounts of processed foods
- Eating fresh vegetables regularly through the day
- Including physical activity into each day
- Not smoking
- Keeping alcohol intake low
The oolong tea company has found several credible scientific papers linking the consumption of oolong tea to various health benefits but cautions consumers wishing to use oolong tea for health purposes to:
(a) consult their doctor first.
(b) note; that if an oolong tea significantly reduces blood glucose, that this could have an adverse effect. (Heavy consumption of authentic Taiwanese Oolong tea is not advised.)
(c.) Ensure that your tea is authentic Taiwanese Oolong tea because fake mass produced oolong teas use pesticides and chemicals to pass off their product as authentic Taiwanese tea. These chemicals can be extremely toxic. Also, the reason for authentic Taiwanese oolongs efficacy is their abundance of anti oxidants.
