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.
Not true. White whole wheat flour is making a good run at becoming part of mainstream American baking. Traditional all-purpose, or white, and whole wheat flours are milled from hard red wheat berries; both flours contain the wheat's endosperm, while whole wheat flour also contains the bran and germ. Whole wheat white flour is milled from the hard white wheat berry. It contains the entire wheat berry; the difference is in the white berry's bran, and the result is a lighter colored, sweeter tasting flour.
