Could a Ketogenic Diet Alleviate Gout?

More than 8 million individuals in the United States have gout, a disease that can cause intense recurrent episodes of debilitating pain, inflammation, and fever. The cause of gout is the accumulation of urate crystals in joints, which continuously reactivate the immune system, leading to activation of the most common type of immune cell in the blood, neutrophils. These periods of immune reactivation are known as flares, and are driven by a protein complex called the NLRP3 inflammasome.

A study has shown that the ketone body β-hydroxybutyrate can specifically inhibit the NLRP3 inflammasome. Ketones are byproducts of fat break-down in the liver that can serve as alternative metabolic fuels for the brain and heart during periods of low carbohydrate intake, such as fasting, or ketogenic diet. They found that feeding rats a high-fat, low-carbohydrate ketogenic diet increased β-hydroxybutyrate levels and protected rats from the joint swelling, tissue damage, and systemic inflammation normally seen during gout.
