The prevalence of type 2 diabetes is becoming increasingly high around the world, estimated at 9% of the global population over 18+ years old (Virtanen 1088). This increase in type 2 diabetes has been generally attributed to the obesity epidemic. Type 2 diabetes is a metabolic disease caused by insulin resistance and followed by progressive beta-cell death. It affects how the body metabolizes glucose, its main source of fuel. According to Ward (2015), eggs are a main source of cholesterol, with one medium egg containing roughly 200mg, and is associated with elevated blood glucose and an increased risk of Type 2 diabetes. The health claim suggests that higher intake of eggs is associated with a lower risk …show more content…
The study was conducted over a long period with an average follow-up of 19.3 years. Virtanen’s study (2015) involved a prospective, population-based cohort study including over 2,300 men, recruited into 2 cohorts. Cohort 1 assessment consisted of 1166 men who were 54 years old and enrolled in 1984-1986. Cohort 2 assessment included 1516 men who were 42, 48, 54, or 60 years old and enrolled in 1986-1989 (p. 1089). Subjects were given self-administered questionnaires to assess type 2 diabetes such as family history, medical history and medications, smoking, alcohol consumption, and physical activity. Researchers also took baseline measurements of dietary intake, blood pressure, fasting blood glucose, serum insulin, and lipoproteins. The study also had re-examinations of these measurements at 4, 11, and 20 years after baseline to assess type 2 diabetes risk. Outcome measures relevant to prevalence of type 2 diabetes include serum triglyceride levels, lipoprotein levels, plasma glucose levels, and serum insulin levels. After the follow-up of the study was conducted and analyzed, Virtanen et. Al (2015) concluded that “those in the higher quartile of egg intake had a 38% lower risk of incident type 2 diabetes (p. 1095). These results offer evidence that egg consumption is associated
