@arpan Avoid or limit added sugars, highly processed foods, and foods high in saturated fats
This is especially important for people who have Hashimoto's thyroiditis
These foods may increase cholesterol
void grapefruit or grapefruit juice, coffee, foods that contain soy or cottonseed meal, walnuts, or dietary fibers for at least four hours after taking hormone replacement medication, such as levothyroxine (Synthroid, Levoxyl, Levothroid, Unithyroid) as these foods may impact how the body absorbs the medication or decrease its potency
Foods high in fiber, high in calcium, or high in iron may lower the effective dosage of thyroid medication when eaten within four to five hours of taking thyroid medication
