The term castration is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy or, in animals, spaying. Estrogen levels drop precipitously following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body.
Grains, beans, vegetables and nuts all contain glucose, but not typically very much. Usually bread contains 0.5 gram of glucose or less per 1-ounce slice. Navy or pinto beans also offer less than a half-gram of glucose for a 1-cup serving.
Plants store glucose as the polysaccharide starch. The cereal grains (wheat, rice, corn, oats, barley) as well as tubers such as potatoes are rich in starch. Starch can be separated into two fractions-- amylose and amylopectin.
