Diet sodas may not be helping you lose weight—in fact, these and other artificially sweetened foods may sabotage your diet by confusing and rewiring your brain’s reward centers. This study from the journal Physiology & Behavior is yet another example of how lifestyle choices can alter your brain—negatively or positively. Continue reading
Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, enabling humans to predict the actions of people with different values than their own.

The genes you inherit from your parents strongly affect your health and longevity. But you can influence your genes in a healthy fashion using the proper herbs, nutrition and lifestyle choices. Research shows that the natural chemicals in particular foods and botanicals send signals to DNA, optimizing cellular function and keeping illness at bay. Even positive emotions can help DNA yield better health.
We are all born with a certain genetic makeup, and scientists once believed that this blueprint was permanent and unchangeable — essentially that our DNA dictated our destiny. However, an exciting new field of genetic science is emerging which demonstrates that our gene expression can be influenced and altered for better or worse, based on internal and external triggers. These influences on our genes can change how we age, how our bodies react to lifestyle and environmental factors, how we resist illness and even how we gain weight.
Epigenetics is the study of how various factors affect our genes. Advances in this field are showing how environment, diet, lifestyle and even thoughts and emotions can have just as powerful an impact on gene function as biological lineage. Small changes in the expression of one master regulator gene, originating in a number of potential influences, Continue reading
As a group, Americans are the heaviest people in the world. We’re suffering a weight epidemic of massive proportions that bulges out on our hips, thighs and stomachs. But if you’re part of this group and want to bring your weight down, changing six aspects of your lifestyle may help take off pounds.
Many experts have warned that the growing number of overweight people in the United States represents a growing public health menace. But the Centers for Disease Control and Prevention (CDC) notes the problem seems to be just about out of control: 73 percent of us are overweight, and about 40 percent of overweight people are heavy enough to be classified as obese.
While overweight and obesity Continue reading
