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.
Phytatesâwhich are present in whole-grain breads, cereals, legumes, and other foodsâbind zinc and inhibit its absorption [2,12,13]. Thus, the bioavailability of zinc from grains and plant foods is lower than that from animal foods, although many grain- and plant-based foods are still good sources of zinc [2].
Many are aware of zinc issues and as result, zinc supplements have become very commonplace. As with other trace minerals, zinc is better absorbed from animal sources, rather than plant sources. Foods high in zinc include: oysters, beef, crab, lobster, pork chop, chicken, cashews and almonds. Zinc is a part of every living cell, and more than 75 enzymes contain zinc (9).
