Chocolate has a number of extremely appealing sensory qualities, and often are given by patients to those working in hospital wards as a token of their gratitude. This study examines whether this has any harmful effects. Eighty nine qualified nurses, 21 ward assistants, and 18 nursing students completed a structured questionnaire, showing that on average 5.4 chocolates were eaten each day. About 2/3 of the recipients ate 1-5 chocolates a day, while a few (3%) ate more than 20 per day. The most common reason given for eating them was simply because they were there.
Human social interaction is strongly shaped by other-regarding preferences, that is, a concern for the welfare of others. These preferences are important for a unique aspect of human sociality-large scale cooperation with genetic strangers-but little is known about their developmental roots. Here we show that young children's other-regarding preferences assume a particular form, inequality aversion that develops strongly between the ages of 3 and 8.
BACKGROUND: Studies suggest cardioprotective benefits of dark chocolate containing cocoa. OBJECTIVE: This study examines the acute effects of solid dark chocolate and liquid cocoa intake on endothelial function and blood pressure in overweight adults. DESIGN: Randomized, placebo-controlled, single-blind crossover trial of 45 healthy adults [mean age: 53 y; mean body mass index (in kg/m(2)): 30]. In phase 1, subjects were randomly assigned to consume a solid dark chocolate bar (containing 22 g cocoa powder) or a cocoa-free placebo bar (containing 0 g cocoa powder).
