The chickenpox vaccine is a shot that can protect nearly anyone who receives the vaccine from catching chickenpox. It's also called the varicella vaccine, because chickenpox is caused by the varicella-zoster virus. The vaccine is made from a live but weakened, or attenuated, virus. Viruses that have been attenuated are less virulent than viruses that are not.
The term whole grain refers to a variety of grains, including wheat, corn, rice, oats and rye, which are still in their natural form. Whole grains have a bran, germ and endosperm. To be considered a whole grain, the entire grain must still be intact and not just the endosperm, as is the case in refined grains.
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.
