Abstract

Many agricultural populations are subject to chronic or seasonal undernutrition, reproductive women and children often being most vulnerable. This paper presents quantitative and qualitative data on food consumption, food distribution practices, food taboos, garden sizes and work effort to show how Lese horticulturalist women living in the Ituri Forest of northeast Democratic Republic of Congo attempt to alleviate nutritional stress. The Lese experience an annual hunger season when approximately one quarter of the population suffer from energy deficiency. Nutritional intake is also compromised by a complex system of food taboos against meat from wild forest animals. Anthropometric data collected over several years suggest that Lese women suffer from nutritional stress more than men during the hunger season. They also have more food taboos particularly during pregnancy and lactation. Their low fertility is compounded by nutritional stress. Despite these inequities, Lese women use several strategies to improve their food intake. Since they are responsible for all household cooking, they manipulate food portions. During the hunger season, they snack frequently, and increase their consumption of palliative foods. Women with more food taboos plant larger gardens to supplement their diet with vegetable foods. Although this results in their consumption of more daily protein, they work harder compared to women with smaller gardens. Women cheat in their adherence to specific food taboos by actively discounting them, or by eating prophylactic plants that supposedly prevent the consequences (usually illness) of eating tabooed foods. In addition, women resort to subterfuge to access desirable resources. Lese women do not reduce work effort during the hunger season, but adapt physiologically by reducing resting metabolic rates during periods of weight loss. These results point to the ability of Lese women to minimize the ecological and cultural constraints on their nutrition. More data, however, are required to assess the long-term effectiveness of these strategies.

摘要

许多农业人口长期或季节性营养不良,育龄妇女和儿童往往最为脆弱。本文提供了关于食物消费、食物分配方式、食物禁忌、菜园规模和劳动强度的定量和定性数据,以展示生活在刚果民主共和国东北部伊图里森林的莱塞族园艺妇女如何试图缓解营养压力。莱塞族人每年都会经历一个饥饿季节,约四分之一的人口会出现能量不足。一套复杂的食物禁忌体系,即禁止食用野生森林动物的肉,也会影响营养摄入。多年收集的人体测量数据表明,在饥饿季节,莱塞族妇女比男子更容易遭受营养压力。她们还有更多的食物禁忌,尤其是在怀孕和哺乳期。营养压力加剧了她们的低生育率。尽管存在这些不平等现象,莱塞族妇女仍采用多种策略来增加食物摄入量。由于她们负责所有家庭烹饪,所以会控制食物分量。在饥饿季节,她们频繁吃零食,并增加对缓解性食物的消费。食物禁忌较多的妇女会种植更大的菜园,用蔬菜补充饮食。尽管这使她们每天摄入更多蛋白质,但与菜园较小的妇女相比,她们劳作得更辛苦。妇女们会通过主动忽视特定食物禁忌,或食用据说能预防食用禁忌食物后果(通常是疾病)的预防性植物,来违反这些禁忌。此外,妇女们会采取诡计获取想要的资源。莱塞族妇女在饥饿季节不会减少劳动强度,而是通过在体重减轻期间降低静息代谢率来进行生理适应。这些结果表明,莱塞族妇女有能力将生态和文化对其营养的限制降至最低。然而,需要更多数据来评估这些策略的长期效果。
