Global average human diet and protein composition and usage of crop-based products [11] (more statistics) Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. [12] Most human plant-based food calories come from maize, rice, and wheat. [13]

Jaws allow fish to eat a wide variety of food, including plants and other organisms. Fish ingest food through the mouth and break it down in the esophagus. In the stomach, food is further digested and, in many fish, processed in finger-shaped pouches called pyloric caeca, which secrete digestive enzymes and absorb nutrients.
[52] [53] [54] About 182 fish consume seeds or fruit. [55] Animals (domesticated and wild) use as many types of grasses that have adapted to different locations as their main source of nutrients. [56] Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. [57]

Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish.Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins).
Fish sizes vary by species. Good-quality sardines should have the head and gills removed before packing. [4] They may also be eviscerated before packing (typically the larger varieties). If not, they should be purged of undigested or partially digested food or feces by holding the live fish in a tank long enough for them to empty their ...
The human population exploits and depends on many animal and plant species for food, mainly through agriculture, but also by exploiting wild populations, notably of marine fish. [ 10 ] [ 11 ] [ 12 ] Livestock animals are raised for meat across the world; they include (2011) around 1.4 billion cattle , 1.2 billion sheep and 1 billion domestic pigs .
