Aquatic foods are micronutrient-rich and utilised by coastal communities across the globe. However, the contribution of aquatic foods sourced from mangroves to nutrient intake is relatively unknown, despite thousands of people reliant on their resources in coastal regions across the globe. This case study aimed to quantify the nutrient contribution that aquatic foods make to mangrove fishers' household dietary requirements in a community in West Kalimantan, Indonesia.
A seven-day household weighed food record of all aquatic food consumed was conducted twice to capture seasonal variability, in the wet (n = 59) and dry seasons (n = 54). Records were analysed using nutrition composition datasets for finfish and shellfish. The contribution aquatic foods make to the recommended nutrient intake (RNI) was described for seven nutrients: calcium, iron, selenium, zinc, vitamin A, omega-3 essential fatty acids and protein. The total quantity of each species consumed for each season was determined to calculate the average per-person nutrient intake from each species and from all aquatic food species combined. We then compared these to each of the RNI sex and age categories and aggregated it to present an average (%) RNI for the total sample and by season.
Households consumed more meals containing aquatic food in the dry season (390 meals) compared to the wet season (337 meals). Aquatic foods contributed to all seven nutrients analysed, mostly to the RNIs for selenium (127% wet season and 193% dry season), protein (27% wet season and 35% dry season), omega-3 essential fatty acids (21% in both seasons), and zinc (10% wet season and 17% dry season). Contribution to iron reduced from 11 to 10% between the wet and dry seasons and increased from 8 to 10% for calcium and 4-7% for vitamin A between the wet and dry seasons respectively.
Our findings indicate that mangrove aquatic foods provide important nutrients in local seasonal diets in West Kalimantan. Given the nutritional challenges Indonesia faces, sustaining local engagement with mangroves as a food system should be considered in the aquatic foods discourse and nutrition projects, as well as mangrove conservation and management strategies.
水产品富含微量营养素，全球沿海社区都有食用。然而，尽管全球沿海地区有成千上万人依赖红树林资源获取食物，但来自红树林的水产品对营养摄入的贡献相对未知。本案例研究旨在量化印度尼西亚西加里曼丹一个社区中，水产品对红树林渔民家庭饮食需求的营养贡献。
对所有食用的水产品进行了两次为期七天的家庭称重食物记录，以捕捉季节变化，分别在雨季（n = 59）和旱季（n = 54）进行。使用鱼类和贝类的营养成分数据集对记录进行分析。描述了水产品对七种营养素推荐摄入量（RNI）的贡献：钙、铁、硒、锌、维生素A、ω-3必需脂肪酸和蛋白质。确定每个季节每种物种的消费总量，以计算每人从每种物种以及所有水产品物种组合中摄入的平均营养素。然后，我们将这些与每个RNI性别和年龄类别进行比较，并汇总以呈现总样本和按季节划分的平均（%）RNI。
与雨季（337餐）相比，旱季家庭食用含水产品的餐食更多（390餐）。水产品对所有七种分析营养素都有贡献，主要是对硒的RNI（雨季127%，旱季193%）、蛋白质（雨季27%，旱季35%）、ω-3必需脂肪酸（两个季节均为21%）和锌（雨季10%，旱季17%）。对铁的贡献在雨季和旱季之间从11%降至10%，对钙的贡献从8%增至10%，对维生素A的贡献在雨季和旱季之间分别从4%增至7%。
我们的研究结果表明，红树林水产品在西加里曼丹当地季节性饮食中提供重要营养素。鉴于印度尼西亚面临的营养挑战，在水产品相关讨论和营养项目以及红树林保护和管理策略中，应考虑维持当地将红树林作为食物系统的参与度。
