INTERNATIONAL DAYAWARENESS

World Iodine Deficiency Day

Every year on October 21, a tiny pinch of iodized salt protects growing brains and healthy bodies. World Iodine Deficiency Day raises awareness about iodine, the essential micronutrient that powers the thyroid gland and supports healthy growth and development, especially in children and expectant mothers. It is a small nutrient with an enormous job.

3 ways to celebrate

AT HOME

Switch to iodized salt

Check your kitchen salt for the word iodized and make it the household default, since universal salt iodization is the simplest shield against deficiency.

WITH FRIENDS

Host an iodine quiz

Run a fun nutrition quiz about iodine-rich foods and thyroid health, sharing one fact that each person can pass on to their family.

AT WORK OR SCHOOL

Bring nutrition to the classroom

Ask a nurse or nutritionist to give a short talk or poster session on iodine's role in brain development and healthy growth.

Plan ahead
