Bodybuilders and other athletes interested in gaining muscle have an interest in boosting their levels of testosterone and other growth factors and maximizing their utilization of protein and its incorporation into muscle cells. Typical recommendations usually include very high amounts of protein, but exclude foods like liver that are high in vitamin A, and low-fat recommendations all but banish vitamin A entirely from the diet by excluding foods such as full-fat milk. The combination of a high-protein diet that depletes vitamin A and a low-fat diet that fails to provide vitamin A is a clear recipe for deficiency of this vital nutrient. Exercises that elicit a high demand for testosterone, such as squats and deadlifts, are often recommended for muscle growth, but without vitamin A the body cannot meet that demand for testosterone. It's high time for athletes to forget the modern mantras and remember the dietary wisdom of the past, achieving a lean, muscular physique through traditional foods such as liver, egg yolks, full-fat milk, butter from grass-fed cows and cod liver oil.
