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].
12. Zinc is not found in large amounts in plant foods, but as far as can be detected, vegetarians have similar zinc status to non-vegetarians (6). The best, common plant sources of zinc are legumes, nuts, seeds, and oatmeal.Table 2 shows the zinc content of selected plant foods.ne caveat is that serum zinc levels are not necessarily indicative of the zinc levels in cells (8). Protein increases zinc absorption. Because of this, foods high in protein and zinc, such as legumes and nuts, are good choices (2).
