One of the most famous pirates is Blackbeard. His real name is Edward Teach, and he went around frightening people into giving him money and suchlike. Despite having a reputation of being a bit of a troublemaker, there is no record of him actually murdering any of his prisoners.
Oats are also commonly used as feed for horses when extra carbohydrates and the subsequent boost in energy are required. The oat hull may be crushed (rolled or crimped) for the horse to more easily digest the grain, or may be fed whole. They may be given alone or as part of a blended food pellet.
The main problems with oats are the phytic acid and the avenin, a protein in the prolamine family (along with gluten from wheat, rye, and barley, and zein, from corn). As far as phytic acid (or phytate) goes, oats contain less than corn and brown rice but about the same amount as wheat.
