It seems there is a positive correlation between rice content and arsenic level in foods. This is of extraordinary importance for infants below 1 y of age because their diet is very limited and in some cases is highly dependent on rice-based products; this is particularly true for infants with the celiac disease because they have no other option than consume gluten-free products, such as rice or corn. Arsenic contents were significantly higher (P < 0.001) in gluten-free infant rice (0.057 mg kg⁻¹) than in products with gluten, based on a mixture of cereals (0.024 mg kg⁻¹). Besides, especial precaution must be taken when preparing rice-based products at home, because arsenic content in Spanish rice was high, with levels being above 0.3 mg kg⁻¹ in some cases.
From the data presented in this manuscript, it seems imperative that legislation on maximum residues of arsenic in food should be available as soon as possible to protect consumers worldwide. Research is needed to identify or breed rice cultivars with low accumulation of arsenic in the grain; otherwise the rice percentage in infant foods should be reduced.
食物中的大米含量与砷含量之间似乎存在正相关关系。对于 1 岁以下的婴儿来说，这一点非常重要，因为他们的饮食非常有限，在某些情况下，他们的饮食高度依赖于以大米为基础的产品；对于患有乳糜泻的婴儿来说尤其如此，因为他们除了食用无麸质产品（如大米或玉米）外别无选择。无麸质婴儿米（0.057mg/kg）中的砷含量明显高于含有麸质的混合谷物产品（0.024mg/kg）（P<0.001）。此外，在家中制备基于大米的产品时必须特别小心，因为西班牙大米中的砷含量很高，在某些情况下含量超过 0.3mg/kg。
从本文提供的数据来看，尽快制定关于食品中砷的最大残留量的法规来保护全世界的消费者似乎势在必行。需要开展研究以确定或培育砷在谷物中积累量低的大米品种；否则，婴儿食品中大米的比例应降低。
