Liberals do drink more lattes, but maybe not for the reasons you think -- ScienceDaily

In fact, only 16% of liberals, 11% of moderates, and 9% of conservatives prefer lattes. In exploring why liberals show a stronger preference for lattes, the researchers considered numerous factors, including the availability of lattes in one's local area, household income, and gender. Although all of these were predictors of latte drinking, none of them explained the relationship between lattes and liberals. However, latte drinkers' attitudes toward globalization proved most meaningful in explaining why liberals are more likely to drink lattes.

"Caffeine helps meetings!" or "coffee addicts function badly without coffee?"

Researchers found that people gave more positive reviews for their group's performance on a task -- and their own contribution -- if they drank caffeinated coffee beforehand. A second study showed that people talked more in a group setting under the influence of caffeinated coffee -- but they also were more on-topic than those who drank decaf. Coffee seems to work its magic in teams by making people more alert, said Amit Singh, co-author of the study and a doctoral student in marketing at The Ohio State University's Fisher College of Business. "We found that increased alertness was what led to the positive results for team performance," Singh said. "Not surprisingly, people who drank caffeinated coffee tended to be more alert." Singh conducted the study with Vasu Unnava and H. Rao Unnava, both formerly at Ohio State and now with the Graduate School of Management at the University of California, Davis. The study appears online in the Journal of Psychopharmacology. While many studies have looked at how caffeine affects individual performance, this is the first to examine the impact it has on teams, Singh said. The first study involved 72 undergraduate students who said they were coffee drinkers. They were instructed not to drink coffee before the experiment. Half of them first participated in what they were told was a coffee-tasting task. They were split into groups of five. After drinking a cup of coffee and rating its flavor, they were given 30 minutes of filler tasks to give the caffeine a chance to kick in. The other half of the participants did the coffee tasting at the end of the experiment.

Coffee affects cannabis and steroid systems -- ScienceDaily

Blood metabolites of the endocannabinoid system decreased with coffee consumption, particularly with eight cups per day, the study found. The endocannabinoid metabolic pathway is an important regulator of our stress response, Cornelis said, and some endocannabinoids decrease in the presence of chronic stress. "The increased coffee consumption over the two-month span of the trial may have created enough stress to trigger a decrease in metabolites in this system," she said. "It could be our bodies' adaptation to try to get stress levels back to equilibrium." The endocannabinoid system also regulates a wide range of functions: cognition, blood pressure, immunity, addiction, sleep, appetite, energy and glucose metabolism.

Stairs are the new stimulants

"We found, in both the caffeine and the placebo conditions, that there was not much change in how they felt," said Patrick J. O'Connor, a professor in the department of kinesiology who co-authored the study with former graduate student Derek Randolph. "But with exercise they did feel more energetic and vigorous. It was a temporary feeling, felt immediately after the exercise, but with the 50 milligrams of caffeine, we didn't get as big an effect."
