Many researchers have proved that chocolate improves language learning because it contains sugar and stimulates serotonin levels in the brain, making learners happier. Leche and Melk (2001), for example, assessed 300 students and established that those learning a language often needed to increase their sugar levels. The majority of students in their study (80%) indicated that chocolate was their main source of sugar when they were studying. They benefitted more from dark chocolate than from milk chocolate, and each student required on average 50g of chocolate per thirty minutes of study time. A later study (Leite, 2008) involved 500 university students of Japanese, each of whom was given 100g of milk chocolate every fifteen minutes for three hours. This study was unsuccessful, however, as although these students derived much pleasure from the study few of them actually proceeded to submit their essays, as they were too full of chocolate to complete their assignments. A more recent study of English language students (Amargo, 2013), financed by a chocolate maker, found varying results. Those students who had eaten 100g of dark chocolate daily during the week long study responded to the questionnaire at the end of the study period, but those who had eaten 1kg of white chocolate daily failed to respond, and it was assumed that they were feeling too sick to continue the research. Since dark chocolate is linked to increased serotonin levels those students who ate dark chocolate in the study may have become happier and more motivated. From all these studies it can therefore be assumed that moderate amounts of dark chocolate may be beneficial to study, but that larger amounts of chocolate, particularly milk or white chocolate, may be harmful to general health.
