The domestic silkworm Bombyx mori produces the majority of the world's silk, subsisting almost entirely on mulberry leaves. After reaching adulthood, the silkworm produces a fine fibre that is wound into a compact cocoon. Fibroin, which makes up the core filament, and sericin, a gooey substance that holds it all together, are the two main proteins that make up the fibre. The individual filaments of silk are slowly and carefully unwound from the cocoon and reeled together to create one very long, continuous strand of silk yarn. Silk is an entirely natural fabric if it is left undyed and untreated.

Beetroots are a type of root vegetable that is distinguished by their rich, dark red color. This color is caused by the presence of betalain, a red pigment that is responsible for the vegetable's bright coloring. This same pigment, however, might cause your feces to become black after ingesting beetroots. This is due to the fact that betalain does not break down in the digestive system and instead travels through the body and is expelled in the stool.
