Overconsumption of fatty, sugary foods leads to changes in brain receptors, according to new animal research at Johns Hopkins University School of Medicine. The new research results are being presented at the 2009 annual meeting of the Society for the Study of Ingestive Behavior (SSIB), July 28 - August 1, 2009, the foremost society for research into all aspects of eating and drinking behavior. The results have implications for understanding bulimia and other binge eating disorders. Dr. Bello and colleagues report that either continuous eating or binge eating a high fat, high sugar diet alters opioid receptor levels in an area of the brain that controls food intake.
New imaging technology provides insight into abnormalities in the brain circuitry of patients with anorexia nervosa (commonly known as anorexia) that may contribute to the puzzling symptoms found in people with the eating disorder. In a review paper published on line in Nature Reviews Neuroscience, Walter Kaye, MD, professor of psychiatry and director of the Eating Disorders Program at the University of California, San Diego, and colleagues describe dysfunction in certain neural circuits of the brain which may help explain why people develop anorexia in the first place, and behaviors such as the relentless pursuit of dieting and weight loss.
Sufferers of eating disorders have problems with certain mental tasks; this is the finding of a comprehensive overview of studies examining the link between cognitive deficits and eating disorders, published online in the Journal of Neuropsychology today, 22nd July 2009. Professor Konstantine Zakzanis from the University of Toronto carried out an analysis of 27 studies that investigated the thinking of 608 anorexia nervosa sufferers, and 14 studies of 347 bulimia nervosa patients to look for consistent patterns in cognitive deficits. Professor Zakzanis said: "Over the last 30 years, many psychological studies have tested people with anorexia or bulimia on tasks such as decision making, verbal memory and reaction times and have found that people with eating disorders perform worse than people who don't have an eating disorder.

Scurvy is a condition where an individual has a vitamin C (ascorbic acid) deficiency. The name scurvy comes from the Latin scorbutus, and humans have known about the disease since ancient Greek and Egyptian times. Scurvy commonly is associated with sailors in the 16th to 18th centuries who navigated long voyages without enough vitamin C and frequently perished from the condition. Modern cases of scurvy are very rare. Humans are unable to synthesize vitamin C - which is necessary for collagen production and iron absorption - and so they must obtain it from external sources (such as citrus fruits). Therefore, people must consume fruits and vegetables that contain or are fortified with vitamin C in order to avoid the vitamin C deficiency known as scurvy.
