High fiber intake: indicator of a healthy lifestyle
Article Abstract:
The association between a high-fiber diet and a reduced risk of heart disease could be explained by the fact that a high-fiber diet is a marker of a healthy lifestyle. A 1996 study reported that male physicians who ate a high-fiber diet had a lower risk of heart attack. However, the reduction was most significant in the men who ate the most fiber. These men also exhibited several other healthy behaviors, such as a smoking rate much lower than average. The results were adjusted for the energy intake, but energy is associated with fat. Other studies have shown that a high-fiber diet replaces fat in the diet, which could explain the health benefits of such a diet. The 1996 study found that breakfast cereal was a major source of fiber in the physicians' diets. But skipping breakfast has been linked to high cholesterol levels in children, perhaps because they eat high-fat foods to make up for a missed breakfast. Eating breakfast could also be a marker of a healthy lifestyle.

Handheld Cellular Telephone Use and Risk of Brain Cancer
Article Abstract:
There was no link between cell phone use and brain cancer in a study of 469 men and women with brain cancer and 422 people without brain cancer. However, further studies are needed to determine whether slow-growing tumors might be caused by exposure to radio waves from cell phones.
