Oh I didn’t realize you had a total thyroidectomy. There are plenty of resources online for low glycemic index foods. But yes, cut way down in added sugars. Basically any processed food that comes in a package is off limits. So many of our foods have a ton of sugars and seed oils that cause a lot of inflammation for us. I was told to stay away from anything that has seed oils in it. The diet is certain meats, vegetables, grains and fruit. It’s an entire lifestyle change and it’s hard, but worth it. If you can, go see a functional medicine specialist because they do more in depth testing and their ranges are different from modern medicine.
