The two pieces of evidence the author uses to support the idea that taking iodine out of table salt might cause harm are:
- "Experts are concerned that people who still rely on table salt as a source of iodine will have an increase in disease caused by a diet lacking in the micronutrient."
- "In 1924, iodine was added to salt to make up for a lack of public access to dairy foods and ocean fish, which are natural sources of iodine."
These points highlight the importance of iodine and the potential health risks associated with its absence in the diet, particularly for those who depend on table salt for their iodine intake.
