Soybean seeds are an important and economical source of protein in the diet of many developed and developing countries. Soy is a complete protein, and soyfoods are rich in vitamins and minerals. Soybean protein provides all the essential amino acids in the amounts needed for human health. Recent research suggests that soy may also lower risk of prostate, colon and breast cancers as well as osteoporosis and other bone health problems and alleviate hot flashes associated with menopause. This volume is expected to be useful for student, researchers and public who are interested in soybean. Hany A.

Introduction Soybean is a leguminous plant native to eastern Asia (Liu et al. 2008). Soybean is cultivated worldwide, with the U.S. being responsible for more than 50% of the world's production of this important food. Soybean grains are rich in protein content (see aminoacids composition, Table 1); therefore constitute a useful source of food. It is consumed as cooked beans, soy sauce, soy milk and tofu (soybean curd). Also, a vegetable oil is obtained from soybeans, rich in polyunsaturated fatty acids. This legume is also a good source of several phytochemicals such as isoflavones and lignans, molecules with antioxidant properties that, among other effects, might help to fight and prevent several pathologies. For these reasons, these compounds have been intensively studied at basic and at the clinical level. Soybean consumption benefits, especially in the cardiovascular system, have been related to its important protein content, high levels of essential fatty acids, vitamins and minerals. Nevertheless, there has been controversy as to the extent to which soybean is a health- promoting food. We address some aspects of these issues in this chapter. 2. Agronomic characteristics of soybean plants Soybean (Glycine max L. Merr., subfamily Papilionoidae) is an annual plant that measures up to 1.5 m tall, with pubescent leaves and pods. The stems are erect and rigid. The root system has as main root which can reach a meter deep, the average being between 40 and 50 centimeters. In its primary and secondary roots, are located a variable number of nodes. One of the characteristic of the root system development is its sensitivity to variations in the supply and distribution of inorganic nutrients in the soil (Forde & Lorenzo 2001). Soy leaves are alternate, compound (trifoliate), with the exception of the basal leaves, which are simple. The leaflets have an oval - lanceolate with a green color turning yellow, at maturity stage. Soybean flowers are found in variable number of axillary racemes as 2 Soybean and Health inflorescences with white or purple colors, depending on the variety. Fruits of soy are pods dehiscent on both sutures (Sánchez A et al. 2004). The pods reach two to three inches in length. Each fruit has three to four seeds, yellow, but there are usually black, green and brown seeds, depending on the variety (Nadal S et al. 2004). The phenologic stages of soybean were described by Ferh and colleagues (Fehr et al. 1971). This scale includes the growth stages of soybean (Table 2). The numbering of the vegetative state is determined by the count of existing nodes on the main stem. Above that, usually there are fully developed leaves. A leaf is already fully developed when the edges of the leaflets of the blade located immediately above are not touching. The reproductive stages are based on flowering, growth of pods and seeds and plant maturity.
