Black Coffee


Coffee has become part of a lifestyle that does not merely add to the spirit or consumed to overcome sleepiness. Various studies also indicate that coffee contains antioxidants that are good for preventing free radical damage the body.

However, if brewed or processed in the wrong way, the benefits of coffee can also be reduced. Dr. Mehmet C. Oz, Vice Chairman of Cardiovascular Services at the Department of Surgery, Columbia University Medical Center, provides answers to common questions about coffee.

Mixed milk or "creamer" get rid of antioxidants?
Coffee is generally enjoyed in three ways: black coffee, milk coffee, or coffee with sugar and creamer. Blood tests showed that the level of chlorogenic acids (CGAs, an antioxidant in coffee that plays a role in lowering risk of diabetes) are very different in each group who consumed coffee in three ways. Milk appears to have the least effect on its levels of CGA. While coffee with sugar and creamer reduce CGA levels between 23-29 percent.

Some kind of creamer did play a role in "killing" some healthy compounds in coffee or tea. Casein, a protein present in milk, binding polyphenols in coffee or tea. This will reduce the benefit nonkafein on tea or coffee in large quantities. There are four studies that prove this. However, there are other studies which showed that there was no difference in the levels of polyphenols in tea (including green tea) when tea is mixed with cow's milk or soy milk.

In a study where the difference was not found, most likely because of its casein has been removed. Or, researchers made measurements differently. However, despite the healthy compounds were reduced more than that recommended in the research, you'll still get it.

The best is if you drink tea or coffee without sugar, with only low-fat milk. No sugar, means no extra calories. Meanwhile, full cream milk and some types of creamer was added saturated fat.

Instant coffee or instant coffee?
Although instant coffee has been processed, caffeine and some healthy polyphenols found in instant coffee still preserved. Instant coffee itself was starting to feel the benefits after brewed. Instant coffee is actually a coffee brew is either frozen or dried so that the liquid is gone. But, indeed, some polyphenols and taste diminish. How much of the disappearance, depend on coffee beans, penyeduhannya process, and drying method used.

Nevertheless, instant coffee has other advantages. This type of coffee to get two-thirds more fiber. Size of 354 ml of instant coffee contains about 3 grams of fiber, while instant coffee contains only 1.8 grams of fiber. Fiber helps the body absorb polyphenols content earlier.
