Most prepared foods and restaurant food are not made with iodized salt.
I think that you are probably iodine deficient.
Thyroid hormones control your metabolic rate and thus your body temperatures.
Please check oral body temperatures:
- when you first wake up, should be 97.7 -97.8, higher is OK, 97.3 is a problem
- also check for 98.6 mid-afternoon
- if body temps are low, stop using sea salt and read the Thyroid Basics Explained thread/topic.
Low thyroid function leads to weight gain, loss of energy, loss of metal clarity and depression.
