The clean kind of red meat can be tremendously healthy for you, as it not only has high-quality heme-iron – approximately 12-13 percent, which cannot be found in plant protein sources – and contains high levels of zinc, selenium, creatine and carnosine, according to Martindale, which are important for brain and muscle function and repair, she adds. “Red meat also has omega-3s, vitamins A and E, and vital CLA (fatty chain acids essential for heart health),” Martindale says.
