1) A clinical perspective on breastfeeding and autism

In an article appearing in Medical Hypotheses, a New York-based physician-researcher from the Touro College of Osteopathic Medicine has called for the testing of umbilical cord blood for levels of a growth protein that could help predict an infant's propensity to later develop autism.
Based on an analysis of findings in prior published studies, Touro researcher Gary Steinman, MD, PhD, proposes that depressed levels of a protein called insulin-like growth factor (IGF) could potentially serve as a biomarker that could anticipate autism occurrence.
His research points to numerous prior studies that powerfully link IGF with a number of growth and neural functions. Dr. Steinman -- who has also conducted extensive research into fertility and twinning -- further points to breastfeeding as a relatively abundant source of the protein. He says that IGF delivered via breastfeeding would [...]

2) The influence of food order on healthy food selection at buffets

Every day millions of people stand in line at all-you-can-to-eat buffet lines waiting to satiate their palates with the delicious foods on the line. Most of these people, however, are unaware that food order biases what ends up on their plates: the first food in line is taken the most and biases what else is taken. In fact, this influence is so strong that in a recent study published in Public Library of Science One, Drs. Brian Wansink and Andrew Hanks found that two-thirds of an individual's plate is filled with the first items they encounter. Plus, when less healthy foods are served first, individuals take 31% more total food items.
Drs. Wansink and Hanks conducted their study at a conference where attendees were served a seven-item breakfast buffet. In the dining area, the food items were served on two separate tables just over 50 feet apart. Unbeknownst to the attendees, foods were [...]

3) Relief from emotional lows may be more important to addicts than euphoric highs

Cocaine addicts may become trapped in drug binges - not because of the euphoric highs they are chasing but rather the unbearable emotional lows they desperately want to avoid.
In a study published online in Psychopharmacology, Rutgers University Behavioral and Systems Neuroscience Professor Mark West, and doctoral student David Barker in the Department of Psychology, in the School of Arts and Sciences, challenge the commonly held view that drug addiction occurs because users are always going after the high. Based on new animal studies, they discovered that the initial positive feelings of intoxication are short lived - quickly replaced by negative emotional responses whenever drug levels begin to fall.
If these animal models are a mirror into human addiction, Rutgers researchers say that addicts who learned to use drugs to either achieve a positive emotional state or to relieve a [...]
