Rice comes in an astonishing array of sizes, shapes, and colors. Several distinct varieties of rice are commercially available, including long-grained Thai rice, medium-grain brown rice, short-grained arborio rice, Indian sticky rice, and sweet-smelling jasmine rice, to name just a few. Each kind of rice is especially suited for a particular style of cooking, or a particular type of dish.
Regardless of the variety, all rice starts off as brown rice. The outer layer of the rice grain is called the bran, and this is what gives rice its distinctive brown color. When rice is milled, this outer bran layer is removed, leaving behind a white core that is essentially made up of simple carbohydrates. White rice, whatever its type, is simply rice that has had its bran removed.
The problem with white rice is that this stripped-off bran layer, the part that is removed during the milling process, is rich with nutrients, such as fiber, B vitamins, and minerals. This is why brown rice is nutritionally superior to white rice. For example, every cup of brown rice contains three and a half grams of fiber, while the same amount of white rice contains less than one gram. Increased fiber intake has been shown to reduce the risk of cancer and heart disease.

How much magnesium is said to be contained in 1 cup of brown rice?
选项 A、24.1mg
B、85.8mg
C、150.0mg
D、0.59g
答案B
解析 观察图表会发现一杯糙米中含有85．8mg的镁，因此(B)是正确答案。(A)中24．1mg是指一杯白米中含有的镁，(C)中150．0mg是指一杯糙米中含有的磷，(D)中0．59g是指一杯白米中含有的食用纤维。
