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.

What is said to be a benefit of dietary fiber?
选项 A、Improved digestion
B、Lower blood pressure
C、Stronger immune system
D、Reduced risk of heart disease
答案D
解析 说明文最后一句话Increased fiber in take has been shown to reduce the risk of cancer and heart disease．说明摄取多的纤维素能够有效降低患癌症或心脏病的可能性。因此(D)是正确答案。
