FDNS 4600 1st Edition Lecture 13Outline of Past Lecture I. Research Methods II. What We Eat and DrinkIII. Safety and EfficacyIV. Case report - the case of the egg manV. Meta-analysis of cohort studiesOutline of Current LectureI. RCT – eggs, cholesterol, body weight, university studentsII. Policy – eggs, cholesterol, CVD?III. How could we use these research methods to test:Current LectureI. RCT – eggs, cholesterol, body weight, university studentsa. RCT- gold standard for proving if things like eggs really have a specific outcome. b. Why does the egg group weigh more then the no egg group?i. It happens! It’s random so this was a result. ii. Studies should really try to equalize the baselines to have accurate resultsc. Cholesterol was not statistically different.d. Eggs have less then 100 calories.e. There is a drift in everyone’s weight including the non-egg group.f. Overall change, the non-egg group and egg group increased around the same.g. Concerns about the study, e.g., sample size, study design, length of study, “dose” of eggs, behaviors of students, etc?i. More time may be needed, the groups were around 30 students so they were fairly small, age group, energy balance, and control over external factors like other meals. h. What does this study tell us about effects of eggs on body weight and blood cholesterol?i. Undeterminable because of the age group.i. Why was the control group important (non-EB)?i. Body weight increase and cholesterol j. Are the results generalizable?These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.i. No, results are for younger age group who are well before problems form with cholesterolk. Concerns about the funding source?i. If the research showed that cholesterol showed a great increase, would the results be published?II. Policy – eggs, cholesterol, CVD?a. Main food policy document for US? __Dietary Guidelines___III. How could we use these research methods to test:a. Food and health?b. Supplements?i. Herbsc. Additives?i. GMOs (FDA regulates them)ii. Food colorsd. Toxins?i. Pesticidesii. Cohort Study- look specifically at farmerse. Contaminants?i.
