Sources
The research topic of interest regards the impact of cow milk allergy on children. In a bid to shed more light on the topic, I came up with two articles. The first one is Pensabene, L., Salvatore, S., D'Auria, E., Parisi, F., Concolino, D., Borrelli, O. ... & Saps, M. (2018). Cow’s Milk Protein Allergy in Infancy: A Risk Factor for Functional Gastrointestinal Disorders in Children? Nutrients, 10(11), 1716. The second article that I came up with is Children's National Hospital. "Children allergic to cow's milk smaller and lighter." ScienceDaily. ScienceDaily, 20 December 2019. <www.sciencedaily.com/releases/2019/12/191220074250.htm>. The latter is from a reputable source, while the former is from a questionable one.
Summary of the Articles
The first article focuses on understanding the relationship between cow milk allergy (CMA) and gastrointestinal disorders in infancy. The authors acknowledge that cow milk allergy is a major problem among children with a prevalence of between 2% and 5% (Pensabene et al., 2018). Generally, food allergy is any adverse reaction in the body that occurs after an individual’s exposure to food. The immune reaction either involves antibodies such as the IgE, cell-mediated, or both. According to the authors, the major allergens include whey proteins such as the caseins and the ß-lactoglobulin. Most of the children exhibit IgE CMA demonstrates sensitivity to more than one of the allergens present in the cow milk. Children with allergies end up experiencing numerous gastrointestinal disorders, primarily manifesting in the form of stomach discomfort and diarrhea.

The second article also highlights the impact of cow milk allergy to children. According to the authors, children with this form of allergy are smaller and lighter (Children's National Hospital). The premise is based on the comparison done with children experiencing an allergy to tree nuts or peanuts. The author of the article continues by asserting that 1 in every 13 children has a particular food allergy. The allergies have no cure and can, therefore, present life-threatening conditions to the children. In infancy, many children rely on milk and other milk products as their primary sources of diet. However, when they exhibit an allergy to these foods, they tend to diarrhea a lot and in the process, lose a large amount of water and nutrients. As such, this paves the way for a reduced body mass leading to smallness and lightness.
Difference between the Reliability
First, it is important to acknowledge that both sources have authoritatively addressed the issue regarding the impact of cow milk allergy. However, the first research is more reputable because it emanates from a reliable database known for quality research. The database is known as the US National Library of Medicine. The second article is an internet source that published under the ScienceDaily website. The first article is peer-reviewed by numerous authors. Based on their credentials illustrated at the top, they are well-suited to debate on the issue discussed. However, no specific author has been mentioned in the second article. No signs of peer-review have been witnessed.
Scientific Validity
Scientific valid research has a way of proving premises by using experimental procedures. The first article has a clear methodology that was used to come up with the outcomes. It has visual representations and tabulations with the outcomes of the research. A conclusion demonstrating the implications has also been included. All facts and figures used in the research have been clearly cited. However, the same has is not the case in the second article. Most premises and facts have been mentioned without proper methodology or citation. Despite giving important points, it is difficult to believe as the author has done little to prove their sentiments.
