Purines are the building blocks of DNA or the main materials that make up our cell. When purines break down, they form uric acid. High level of uric acid can cause gout, which is a form of arthritis. This can be extremely painful and taking foods that are high in purines can make the problem even worse. If you have high level of uric acid in your body or you are suffering from gout, it’s best to avoid foods high in purines. Foods that contain 100 mg of purines or lower are considered low in purine. Those that have higher content than that must be avoided, especially those that contain 400 mg purines and up as they have the highest content.
Every 100 grams of brewer’s yeast contain 1810 mg of purines. Baker’s yeast has lower purine content than this, but it’s still high at 680 mg per 100 grams of baker’s yeast. Avoid beers and breads that contain yeast to prevent the build-up of uric acid in your system.
