Mafic is an adjective describing a silicate mineral or igneous rock that is rich in magnesium and iron, and is thus a portmanteau of magnesium and ferric. Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro.
Other good natural sources of taurine include beef, lamb, dark chicken meat, eggs, most dairy products, seaweed, krill and brewerâs yeast. Raw meat is fairly rich in taurine, comparable to fish, but cooked varieties typically have only 10 milligrams of taurine per ounce. To increase the amount of taurine in your meat, consider eating it rare or medium-rare. Organ meats such as liver and heart contain more taurine than choice cuts of flesh.
A relatively small number of foods, however, contain concentrated amounts of purines. For the most part, these high-purine foods are also high-protein foods, and they include organ meats like kidney, fish like mackerel, herring, sardines and mussels, and also yeast.ecause uric acid is formed from the breakdown of purines, low-purine diets are often used to help treat conditions like gout in which excessive uric acid is deposited in the tissues of the body.
