Hashimoto’s Thyroiditis Diet: Best & Worst Food List

Hashimoto’s thyroiditis – also called Hashimoto’s disease – is one of the most common thyroid disorders in the world and can greatly affect quality of life, even if it’s treated with medication. Hashimoto’s thyroiditis is when the thyroid gland is chronically inflamed and slows or stops the production of essential hormones, which can lead to:

• Weight gain
• Dry skin
• Hair loss
• Fatigue
• Constipation

In addition to standard medication, research shows that diet and lifestyle changes may drastically improve symptoms. 

Best Diet for Someone with Hashimoto’s Disease

There’s no specific diet plan that’s proven to treat Hashimoto’s disease, but there are several diets that have evidence of having helped people with Hashimoto’s. The following diets can help those with Hashimoto’s, including but not limited to:

• Gluten-free or grain-free diet. Many people with Hashimoto’s experience food sensitivities, especially to gluten. Unless they also have celiac disease, there’s no current research to support a gluten-free diet for all people with Hashimoto’s.
• Sugar-free diet. If you have Hashimoto’s, eating too much sugar can increase inflammation, provoke autoimmune thyroid flares, throw blood sugar out of balance, create dysfunction in gut health and gut bacteria, and create hormone deficiencies and excesses. 
• Paleo diet. The paleo diet attempts to mimic the eating patterns of our early ancestors with an emphasis on whole, unprocessed foods. The Autoimmune Paleo Diet (AIP) aims to avoid foods that cause inflammation and damage to the gut. 
• Dairy-free diet. Dairy is one of the most problematic foods for people with Hashimoto’s, and eliminating it can help reduce bloating, diarrhea, and acid reflux.
• Low Glycemic Index Diet. A low glycemic index diet is based on an index that measures how each food affects your blood sugar levels. Blood sugar imbalances are common in people with Hashimoto’s and some research indicates that people with this condition are more prone to spikes in blood sugar followed by reactive hypoglycemia after eating a carbohydrate-rich meal. A low glycemic index diet can help keep your blood sugar levels in balance.
