Got milk? If you’re trying to put on muscle, you better. Whole milk was once a staple for guys who were packing away calories and moving massive amounts of iron in order to go from pencil neck to bull neck. These days we know enough to shun or restrict the saturated-fat-filled whole variety in favor of skim, but even the fat-free version has its detractors. Some claims against milk link it to childhood diabetes, while others allege widespread pesticide contamination of dairy products.
