Employees' cafeteria purchases--both healthy and unhealthy foods--were influenced by their co-workers' food choices, found a large, two-year study of hospital employees. The study made innovative use of cash register data to gain insights into how individuals' social networks shape their health behavior. The research suggests we might structure future efforts aimed at improving population health by capitalizing on how one person's behavior influences another.
By targeting a receptor in the brains of mice, researchers have successfully altered feeding and anxiety-like behaviors linked to anorexia.
Two common dietary patterns identified in British adults, which include high intakes of chocolate and confectionary, may be associated with an increased risk of cardiovascular disease and death in middle-age, according to a study published in the open access journal BMC Medicine.
A new mathematical model for the interaction of bacteria in the gut could help design new probiotics and specially tailored diets to prevent diseases. The research, from Chalmers University of Technology in Sweden, was recently published in the journal PNAS.
Children like junk food. As much as 70% percent of their diet is estimated to come from junk foods. While numerous studies have shown the overall negative impact of junk food, few have focused on its direct developmental effects on children, particularly young children.
A new study has shown that underweight and overweight women are at a significantly higher risk of experiencing recurrent miscarriages compared to those of average weight.
Researchers at the Weizmann Institute of Science, together with colleagues from the Queen Mary University of London and the Hebrew University of Jerusalem, have revealed the mechanism of action of the master switch for hunger in the brain: the melanocortin receptor 4, or MC4 receptor for short. They have also clarified how this switch is activated by setmelanotide (Imcivree), a drug recently approved for the treatment of severe obesity caused by certain genetic changes.
It has long been known that obesity is an inflammatory disease. Based on this knowledge, a group of researchers led by Nabil Djouder at the Spanish National Cancer Research Centre (CNIO), decided to try to fight obesity by preventing inflammation. The research, published this week in Nature Metabolism, shows that digoxin, a drug already in use against heart diseases, reduces inflammation and leads to a 40% weight loss in obese mice, without any side effects.
Young adults must step up their exercise routines to reduce their chances of developing high blood pressure or hypertension - a condition that may lead to heart attack and stroke, as well as dementia in later life.
UK adults who are overweight or obese retain their weight over time, which is associated with an increased risk of health complications and death, according to a study published in the open access journal BMC Public Health.
