Sugar-free (SF), sugar-reduced (SR), or low-glycemic-index (low GI) cereal products could be helpful for the dietary treatment of disorders related to glucose homeostasis. However, access and economic aspects are barriers that could hamper their consumption. Thus, the availability and price of such cereal products were evaluated in Northwestern México. The products were categorized in 10 groups. The data were collected in five cities by store visitation (from November 2015 to April 2016). The availability in specialized stores and supermarkets was expressed as availability rates based on the total number of products. The price of the SF, SR, and low GI products were compared with their conventional counterparts. Availability rates were higher in supermarkets than in specialized stores by product numbers (14.29% versus 3.76%, respectively; < 0.001) and by product categories (53.57% versus 26.92%, respectively; < 0.001). Five categories of products labeled as SF, SR, and low GI (oats, cookies and crackers, flours, snacks, and tostadas/totopos) had higher prices than their conventional counterparts ( < 0.05). In conclusion, in Northwestern Mexico, the availability of SF, SR, and low GI cereal-based foods is relatively low, and these foods are more expensive than their conventional counterparts.
无糖（SF）、低糖（SR）或低血糖生成指数（low GI）谷物产品可能有助于治疗与葡萄糖稳态相关的疾病。然而，获取和经济方面的障碍可能会阻碍它们的消费。因此，我们评估了墨西哥西北部此类谷物产品的供应和价格情况。产品分为 10 组。数据通过商店访问（2015 年 11 月至 2016 年 4 月）在五个城市中收集。专门商店和超市的供应情况以产品总数为基础表示为供应率。SF、SR 和 low GI 产品的价格与传统产品进行了比较。从产品数量（分别为 14.29%和 3.76%；<0.001）和产品类别（分别为 53.57%和 26.92%；<0.001）来看，超市的供应率均高于专卖店。五类标有 SF、SR 和 low GI（燕麦片、饼干和薄脆饼干、面粉、小吃和 tostadas/totopos）的产品价格高于传统产品（<0.05）。总之，在墨西哥西北部，SF、SR 和 low GI 谷物食品的供应相对较低，而且这些食品比传统产品更贵。
