How eating nuts can impact your gut health and Hashimoto’s


Nuts are a popular food group (1, 2). They are packed with nutrients—healthy monounsaturated fats, polyunsaturated fats, protein, fiber, vitamin (B, E, K), minerals (selenium, magnesium, copper, potassium), antioxidants, and much more (3-5). These countless health properties of nuts help prevent obesity, diabetes, and heart problems (3, 6-8).

Nuts are reported to protect against inflammation and are often recommended to eat for people with high blood inflammation markers (9, 10). 

However, for a small number of people nuts can cause autoimmune flare-ups. This happens because nuts are dense with protein, which immune cells in the gut can react to.

Flare-ups from nuts can also occur when eating high quantities of a specific type of nut. Our internal research shows that nuts might be the cause of autoimmune flare-ups, as 8 in 100 people reported problems with nuts (the most common being almonds, cashews, macadamias, and walnuts).

If you think you may be sensitive to a nut, eliminate all nuts from your diet for 4–8 weeks. Record all symptoms that improved, and any that worsened. After 8 weeks, start reintroducing nuts to your diet one type at a time, and allow another 4–8 weeks to pass between reintroducing more nuts.


Track your diet in BOOST Thyroid and see how your symptoms change with the consumption or elimination of nuts.
