Food choices affected by what others eat
Our food choices may be influenced by what other people eat, according to new research.
In a meta-analysis of 15 different studies, researchers from the University of Liverpool in the U.K., found consistent evidence that social norms affect food choices. The studies’ participants who saw that others were making low- or high-calorie food choices were more likely to make similar choices. Participants were also more likely to increase caloric intake if they knew that other people were doing the same.
The research, published in the Journal of the Academy of Nutrition and Dietetics, suggests a strong connection between social norms or social identity and eating. Researchers said that consumers can apply their findings and help others eat healthily by setting a good example. They also added that more studies could also help shape food policies and normalize healthy eating habits, which would benefit public health.

High blood pressure in women "more dangerous" than in men
Women with high blood pressure are at higher risk than men for vascular disease, according to a study published in the journal Therapeutic Advances in Cardiovascular Disease.
Researchers found differences in the mechanisms that cause high blood pressure in women, compared to men. This is the first study to consider gender as a way to determine the best treatments for high blood pressure.
The scientists looked at 100 men and women with untreated high blood pressure. All were at least 53 years old. The researchers performed a series of specialized tests to see whether the heart or blood vessels were involved in increasing blood pressure. The tests measured forces involved in circulating blood, and hormone profiles of the mechanisms behind high blood pressure.
Results showed that compared with men who had the same level of high blood pressure, the women in the study had 30 to 40 percent more vascular disease. They also saw physiologic differences in the cardiovascular systems of women, such as the levels and types of hormones involved in regulating blood pressure. Researchers say this can affect the severity of heart disease.
The researchers concluded that treatment should be tailored to the female mechanisms that cause high blood pressure.
