1. Instructions: Suppose that you are working on a project in which you are attempting to answer the following research question: What role does dietary fiber play in good health? Two of the sources you have found on the topic are Source A and Source B (below). In your response, evaluate the credibility of these two sources. State how useful you think each one would be if cited in a research paper. Be sure to examine their credibility and their relevance to your research question. Your response should use transitions to move between ideas, use specific details from the sources, maintain a formal style, and include a concluding statement. (15 points)

Fiber is one of the most important aspects of a healthy diet, yet it is also one of the most ignored. Few people eat enough fiber-rich foods on a daily basis. According to researchers at Fiber Farms' product development, the average adult needs to consume at least 40 grams of fiber each day.
Why? According to these researchers, fiber helps improve digestion, lowers cholesterol, and improves heart health. Getting that much fiber can be difficult, though. While many natural foods such as green beans, oatmeal, and apples contain fiber, most people would need to eat extremely large amounts of these foods to get the recommended amount of fiber. Who wants to eat 14 apples a day?
Fiber Farms' Fiber Essence offers a healthy, convenient solution. Fiber Essence is engineered to provide 40 grams of fiber in just one serving. The easy-to-mix drink powder can be added to water, juice, coffee, or tea. The health benefits of Fiber Essence can be seen immediately. In a study conducted by the Fiber Farms' labs, test subjects consuming one glass of Fiber Essence each day for three months had lower cholesterol than those eating traditional forms of fiber. There's no easier and more beneficial way to stay healthy than Fiber Essence.

"Fiber and Your Health" from a pamphlet published by the Professional Medical Practitioners of America

While many nutrients are necessary to maintain a healthy body, fiber is possibly one of the most important, especially when you are trying to lose weight. The two types of fiber, soluble and insoluble, serve different functions, but both aid in weight loss.
Soluble fiber dissolves in water and helps minimize the amount of cholesterol and sugar your body absorbs from foods. High-carbohydrate foods have more calories, so reducing sugar intake can reduce weight. Insoluble fiber, as the definition implies, does not dissolve in water. Rather, it is like "filler" in the body. It makes you feel full more easily. When you eat lots of insoluble fiber, you feel full more quickly and aren't as tempted to overeat.
Fiber provides other health benefits. Because soluble fiber reduces the amount of cholesterol the body takes in, it can minimize the impact this harmful substance has on your heart. Insoluble fiber plays an important role in digestion. It helps increase the size of stools, making elimination easier.
Should you have questions about how to get enough fiber in your diet — or other questions about your particular health and dietary needs — be sure to contact your physician or a certified nutritionist.
