Shortly after we arrived on campus, Long-time missionary Ivy Salomon told me what was going to happen in January, February, and March: it would be very hard to keep the students attention, because those are the "hunger months". "The crops are all consumed by then, and it's a good thing for sugar cane, because the students can at least fill their bellies a little," she said. Fill their bellies, but that's not a prescription for good nutrition.
Fact of the matter is that students in Ranquitte, like those in the United States, don't get enough of the right stuff. In the U.S., it's fruits and vegetables (plenty of fats, sugars, and proteins, however!). In Haiti, the students don't get enough proteins and fats; sometimes they're short on calories (during the hunger months, for example).
