More info on iodine
If you could add iodine to the foods that have it in some substantial amount it would be awesom. I'm trying to see if I'm gettin enough of all the iodine rich foods I eat (like Greek jogurt, cod, seaweed and more) eggs are the only ones that have it registered.
I'm guessing it's impractical to track iodine accurately. Veggies grown in iodine-rich soil will have more of it: https://www.health.harvard.edu/heart-health/cut-salt-it-wont-affect-your-iodine-intake
BTW it's probably dangerous to increase your iodine intake suddenly: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4490680/
Unfortunately, iodine is one of those nutrients that we don't have good data on. This fact sheet provides information on foods highest in iodine (UK-based): https://www.ign.org/cm_data/Iodine_1.pdf
This resource is more of a deep dive, but gives a good summary of the average amount of iodine in various foods:
It's important to get consistent daily iodine intake to ensure normal thyroid function. Avoid supplementing at doses greater than 150 mcg and consuming foods with excessive iodine content (such as kelp).

Trace has an iodine supplement (drops). Also, seaweed salad is a good source of iodine. I'm a vegan, and my iodine test was a little low recently, so I have switched to iodized salt for cooking, and will supplement a bit.
