Maintaining a high fiber diet may reduce the risk for metabolic syndrome in adolescents, according to a new study.

A high fiber diet incorporates large amounts of dietary fiber into the daily diet. Dietary fiber is found in grains, fruits and vegetables, and may also be referred to as roughage or bulk. Animal products, including meat and dairy, do not contain dietary fiber. Various health benefits have been associated with a high fiber diet; including potential benefits for glucose metabolism in patients with diabetes; however, additional research is necessary before firm conclusions can be made.

According to a new study, hypnotherapy may improve irritable bowel syndrome (IBS) symptoms.

Various forms of hypnosis, trance, and altered states of consciousness have been documented in a number of cultures throughout history. How hypnosis works is not completely understood. Some changes in the body have been associated with hypnosis, including changes in skin temperature, heart rate, intestinal secretions and immune response. Preliminary research suggests that hypnotherapy may lower the sensory and motor component of the gastrocolonic response in patients with IBS.

A RECENT study suggests that yoga may be more beneficial than standard care for patients with chronic lower back pain.

Yoga is an ancient system of exercise, healing and relaxation. Yoga has undergone much scientific study, with various psychological and physical theories suggested. In human research, yoga has been shown to reduce heart rate and blood pressure, increase breath holding time and lung capacity, improve muscle relaxation and body composition, cause weight loss and increase overall physical endurance.

CONTRARY to previous reports, a new study suggests that selenium may not decease lung cancer mortality risk.

Selenium, an essential trace mineral, is required for the functioning of the body's antioxidant enzymes and for cell growth and survival. The role of selenium in cancer prevention has been the subject of recent study and debate. Preliminary evidence suggests selenium may reduce the risk of prostate cancer; however, any role in lung or colorectal cancer is unclear. After the data was adjusted for various variables, including years of smoking and dietary factors, the researchers found that heavy smokers with high selenium blood levels actually had a significantly increased risk of lung cancer death. The authors noted that these results were contrary to their hypothesis that low selenium blood levels may be linked to an increased risk of lung cancer death.
