Take a look at this week’s New York Times Best Seller list (https://www.nytimes.com/books/best-sellers/hardcov…) of hardcover non-fiction. Identify which of these works are primary sources and which are secondary sources. Do a little “digging” and decide which works you would NOT want to use as a source for a college research paper. Explain why.

Put together the following information into a paragraph. Feel free to arrange the elements however you see them making the most sense and to check the sources to elaborate on or better understand the fact. Use the information from this lesson to embed each citation into your own writing remembering to introduce, clearly cite, and explain each fact. Pay attention to where quotations are used below and either paraphrase or maintain the quotation marks.

Topic: Vitamin D is a particularly important nutrient for children.

Fact 1: “Recent case reports highlight the resurgence of rickets in certain groups of breastfed infants. Infants residing in the North, irrespective of skin color, and dark-skinned African American infants residing anywhere in the United States are most vulnerable to nutritional rickets if they are exclusively breastfed past age 6 months without vitamin D supplementation.”

Fact 2: In 2008, the American Academy of Pediatrics doubled the daily recommended intake of Vitamin D to 400 iu because of ongoing cases of rickets caused by Vitamin D deficiency and because “new evidence supports a potential role for vitamin D in maintaining innate immunity and preventing diseases such as diabetes and cancer.”

Fact 4: Only 5% to 37% of infants meet the 2008 recommendation, with breastfed infants at the lower end of the range.
