Bootstrap's CSS is built on Less, a preprocessor with additional functionality like variables, mixins, and functions for compiling CSS. Those looking to use the source Less files instead of our compiled CSS files can make use of the numerous variables and mixins we use throughout the framework.
Oysters contain more zinc per serving than any other food, but red meat and poultry provide the majority of zinc in the American diet. Other good food sources include beans, nuts, certain types of seafood (such as crab and lobster), whole grains, fortified breakfast cereals, and dairy products [2,11].
Certain vegetables are also good sources of zinc. These include soybeans, lima beans and peas. A cup serving of soybeans contains about 9 mg while the same amount of peas and lima beans contain 2 mg of zinc each. Other vegetables that contain zinc include green beans (1 mg) and Brussels sprouts or asparagus (0.5 mg) in a cup serving.
