The Diet Superfruit Revolution of Dr Oz

Dr. Oz, is a surgeon turned television star and author. After his first appearance on The Oprah Winfrey Show in 2004, his popularity soared and Winfrey gave him his own show in 2009. The Dr. Oz Show focuses on personal health and medical issues. His charming demeanor and common sense advice is seen daily in over two and a half million homes. When he announces a new superfruit that can help with weight loss, people listen.

The most popular superfruits that he continues to push are green coffee bean extract, raspberry ketone, and African mango. Are these fruit extracts the miracles he claims them to be or are they just the latest diet fad?

African Mango bear large, mango-like fruits, and are valued for their fat- and protein-rich nuts. After the nuts are dried, they are usually ground to a fine powder and sold as a dietary aid. African Mango has been shown to reduce weight and improve blood test results in a double-blind study. On the Dr Oz website, Dr Tanya Edwards claims to have used it to lose 7 pounds without any other changes to her diet.

Raspberry Ketone is a compound derived from red raspberries. It is used in cosmetics and as a food additive. It has been shown to prevent weight gain by altering the metabolism in the same way that capsaicin does. While no one is sure why, it is believed that raspberry ketone prevents obesity.

In another double-blind study, a correlation has been found between weight loss and green coffee been consumption. It is thought that the green coffee bean reduces the absorption of glucose, lowering the hyperglycemic peak. According to Lindsey Duncan, one of the benefits of green coffee bean extract is that people do not have to do anything different when taking it. They lose weight without exercise or a change in diet. The chlorogenic acid in the bean inhibits glucose production while boosting metabolism. It does all this without the jitters associated with regular coffee beans.

Dr Oz continues to tout these and other superfruits as weight loss miracles but are these just the latest in a long line of dietary fallacies or could these supplements be the key to defeating obesity in the United States?
