Nutrisystem is one of the most popular diet programs in the US. The marketers have invested in many clinical studies to prove the effectiveness of the program. And, Nutrisystem and other “shelf food” diet services are increasingly grabbing attention of the mainstream media and obesed people with their catchy ads. Many people are falling into them just thinking them as the healthiest alternative to their regular meals.
Are these pre-packaged diet foods really better than your healthy regular meals?
And, are they healthy?
Read on to know why nutrisystem might be bad for your health

I don’t why but 2013 just brings some fresh updates on the Mediterranean diet. Three groundbreaking studies on the Mediterranean diet are already published. These studies revealed: longer lifespan, improved cognitive ability, and reduced heart attack risk. Read on to enjoy the full article.
Studies have shown that resveratrol, a natural compound found in colored vegetables, fruits and especially grapes, may minimize the impact of Parkinson’s disease, stroke and Alzheimer’s disease in those who maintain healthy diets or who regularly take resveratrol supplements. Now, researchers at the University of Missouri have found that resveratrol may also block the effects of the highly addictive drug, methamphetamine.
Dennis Miller, associate professor in the Department of Psychological Sciences in the College of Arts & Science and an investigator with the Bond Life Sciences Center, and researchers in the Center for Translational Neuroscience at MU, study therapies for drug addiction and neurodegenerative disorders. Their research targets treatments for methamphetamine abuse and has focused on the role of the neurotransmitter dopamine in drug addiction. Dopamine levels in the brain surge after methamphetamine use; this increase is associated with the motivation to continue using the drug, despite its adverse consequences. However, with repeated methamphetamine use, dopamine neurons may degenerate causing neurological and behavioral impairments, similar to those observed in people with Parkinson’s disease.
“Dopamine is critical to the development of methamphetamine addiction—the transition from using a drug because one likes or enjoys it to using the drug because one craves or compulsively uses it,” Miller said. “Resveratrol has been shown to regulate these dopamine neurons and to be protective in Parkinson’s disease, a disorder where dopamine neurons degenerate; therefore, we sought to determine if resveratrol could affect methamphetamine-induced changes in the brain.”
Using procedures established by Parkinson’s and Alzheimer’s disease research, rats received resveratrol once a day for seven days in about the same concentration as a human would receive from a healthy diet. After a week of resveratrol, researchers measured how much dopamine was released by methamphetamine. Researchers found that resveratrol significantly diminished methamphetamine’s ability to increase dopamine levels in the brain. Furthermore, resveratrol diminished methamphetamine’s ability to increase activity in mice, a behavior that models the hyperactivity observed in people that use the stimulant.
“People are encouraged by physicians and dieticians to include resveratrol-containing products in their diet and protection against methamphetamine’s harmful effects may be an added bonus,” Miller said. “Additionally, there are no consistently effective treatments to help people who are dependent on methamphetamine. Our initial research suggests that resveratrol could be included in a treatment regimen for those addicted to methamphetamine and it has potential to decrease the craving and desire for the drug. Resveratrol is found in good, colorful foods, and has few side effects. We all ought to consume resveratrol for good brain health; our research suggests it may also prevent the changes in the brain that occur with the development of drug addiction.”
