(NaturalNews) While the talking heads on TV frantically warn about the so-called swine flu pandemic that is supposedly on the verge of causing world-wide suffering and death, there's another world-wide health problem of enormous proportions that's here, right now -- being overweight. The World Health Organization (WHO) estimates more than 300 million people across the planet are obese, and another billion more are overweight. Being too fat isn't a cosmetic problem, it's a condition that kills people prematurely by leading to cardiovascular disease, high blood pressure, stroke and type 2 diabetes.
** And now there's evidence that being too fat also causes brain degeneration and maybe even Alzheimer's disease.
In a study just published in the current online edition of the journal Human Brain Mapping, a research team headed by Paul Thompson, senior author and a University of California at Los Angeles (UCLA) professor of neurology, and lead author Cyrus A. Raji, a medical student at the University of Pittsburgh School of Medicine, compared the brains of people who were obese, overweight, and of normal weight. To define the weight categories, the scientists used the Body Mass Index (BMI), to establish that normal weight people had a BMI between 18.5 and 25, overweight people had a BMI between 25 and 30, and obese people's BMI was more than 30.
The scientists wanted to document whether the brains of those in each of the three groups were equally normal and healthy. Surprisingly, they weren't. In fact, the scientists discovered that obese people had eight percent less brain tissue than people with normal weight. In addition, people who were only overweight and not downright obese still showed a loss of about four percent of brain tissue.
