1 Only a few human diseases are triggered by a single gene working by itself. 2  In most cases, a disease results from the actions of many genes. 3  An example of a single-gene disorder is Huntington's disease, which was discussed in the last chapter. 4  One error in one gene leads to the fatal health problems of HD.

Compositionally, cereals consist of 12-14 percent water, 65-75 percent carbohydrates, 2-6 percent lipids and 7-12 percent protein. Cereals are quite similar in gross composition being low in protein and high in carbohydrates (Table 2). Oats and maize however contain relatively large amounts of lipids. Oats contain at least 10 percent lipids, one-third of which are polar lipids (phospho- and galacto-lipids). The lipid content of maize ranges between 0.4 percent and 17 percent, most of which are triacylglycerides (Eliasson and Larsson 1993).
Steel-cut oats, which are chopped into pieces instead of flattened like the other types of oatmeal, take the longest at approximately 30 minutes but have the most flavor. All types of oatmeal are in the grain food group. Oatmeal, like brown rice, bulgur, whole cornmeal and whole wheat, is a whole grain. The 2010 Dietary Guidelines for Americans recommends that whole grains make up at least half of the total grains you consume.
