Market savvy entrepreneurs have created diet programs that emphasize carbohydrate restriction as the key to weight loss. As a consequence, the carbohydrate industry and its associates have lost billions of dollars of revenues.
In response to lost revenues, the carbohydrate industry has commissioned scientific studies, hoping to show that carbohydrates are not the cause of obesity.
A study appearing in the American Journal of Clinical Nutrition has concluded that High Fructose Corn Syrup is not a unique contributor to the obesity epidemic.

The debate on the efficacy of stretching before exercise has been ongoing for several years. Many claim that stretching before exercise is harmful, while others claim that a failure to stretch can result in injury.
A study appearing in the Clinical Journal of Sports Medicine has concluded that stretching immediately before exercise can impair performance on tasks like jumping and power generation. The study recommends that stretching after exercise, or at another time not related to exercise, is best.
This study runs counter to everything that bodybuilders know. Substantial anecdotal evidence exists to support the practice of stretching prior to exercise. Stretching before exercise not only allows for a fuller range of muscular motion, but it prevents injury and can, in some cases, facilitate muscular hypertrophy.
How would you rate the quality of your sleep? What about the quantity? Are you sleeping enough? Perhaps you could be sleeping more...
A study by the Mayo Clinic has shown that melatonin supplementation can help to alleviate RBD - REM behavior disorder. REM is a state of sleep in which the eyes move rapidly, and most dreaming occurs in the REM state.
REM behavior disorder is a violent sleep disorder that is manifested during the REM state and can often involve a person acting out his or her dreams. Sometimes this involves violent behavior like punching and kicking.
It is not yet understood why melatonin supplementation is effective in some cases of RBD. Research is ongoing.
Omega fatty acids are a group of long-chain fatty acids that are utilized by the brain to increase brain signal transmission efficiency, and used by the endocrine system to enhance hormone production.
Until now Omega oils have been derived from animal source. Health concerns have been raised about fish oil and fish oil caplets as some lab reports have demonstrated that contaminants were present in the samples tested.
Scientists have now genetically engineered plants to yield significant amounts of Omega 3 and Omega 6 fatty acids.
This will undoubtedly reduce the cost of Omega 3 and Omega 6 oils, and may also be successful in excluding harmful contaminants from being present in the final product designed from human consumption.
Vitamin E is a fat soluble essential vitamin that protects the body from free radical oxidization. Free radical oxidization is a process whereby free radicals - toxins manufactured in the body as a by-product of metabolic oxidation - interact with oxygen in a way that causes tissue damage. Oxidative stress can result in compromised immune function and can leave the athlete susceptible to various injuries, illnesses and diseases
Vitamin E has long been used by athletes to increase endurance due to its ability to act as an anti-inflammatory, but research is now demonstrating that alpha-tocopherol, a type of vitamin E, may be useful for reducing bladder cancer.
Further research is on-going and will be included in this column as it becomes available.

"Do you have what it takes to succeed?" "Are you the kind of person who is willing to go the extra mile to get the job done?" These are questions that every person asks at least once over the course of a lifetime.
While success is often nothing more than setting into motion the necessary causes and fulfilling the necessary requirements, new research is showing that personality may have more to do with success than previously thought.
Researchers have shown that a persons personality will impact what type of exercise program is appropriate for them, and wether they will stick to a program in the long run. This is straightforward to people who have made a lifestyle of exercising, but is the beginning of formal research into this aspect of the exercise experience.
