ABSTRACT

We compared seasonal changes in food availability between Maya subsistence farmers and modern householders who pursue cash earnings in rural Yucatan. Modern households encourage the substitution of vegetable for animal protein that severely affects them during scarcity season, particularly in small towns. Subsistence households have increased their legume intake when food was scarce. Seasonality had the largest effect on fruit availability. Unable to obtain enough protein and micronutrient rich foods when meats, fruits and vegetables become scarce, modern households make up for it by purchasing more fats and sugars, particularly in large towns with many grocery stores.

摘要

我们比较了玛雅自给农民和在尤卡坦农村追求现金收入的现代住户之间粮食供应的季节性变化。现代家庭鼓励用蔬菜代替动物蛋白，这在稀缺季节对他们造成严重影响，尤其是在小城镇。当食物短缺时，自给自足的家庭增加了豆类摄入量。季节性对水果供应的影响最大。当肉类、水果和蔬菜变得稀缺时，无法获得足够的蛋白质和富含微量营养素的食物，现代家庭通过购买更多的脂肪和糖来弥补，特别是在拥有许多杂货店的大城市。
