The term 'Treat, as Table Salt' can be solved by the 6-letter word 'iodize'. Iodizing salt is a process of adding iodine to table salt in order to prevent iodine deficiency. This process was first introduced in 1924 and has since become a common practice in many countries. Iodine is an essential nutrient for human health, and iodizing salt helps to ensure that people have access to this important mineral.
