1: Nutrigenomics is a term used to describe:
how genes affect your body’s response to food
how your food affects your genes
one’s dietary genetic profile
2: Nutrigenetics is a term used to describe:

- how food affect your genes
- 3: There is a lot of information on the internet about genetic testing for people who are interested in learning more about their genealogy and disease risk. However, recent studies have raised questions about the reproducibility of some of these tests. DNA Tests Researchers are working hard to identify SNPs that alter disease risk. One example was the discovery that SNPs in genes that encode for the proteins apolipoprotein C3 (APOC3) and apolipoprotein A1 (APOA1) increase the risk for developing metabolic syndrome in people who consume Western diets. You are a physician at a local hospital and you suspect that one of your patients might have these altered SNPs. The patient’s insurance will not cover the test, but you suspect that the hospital might be willing to pay for the test if it is going to help this patient. Explain to your hospital administrators why you want to test your patient for this SNP and how the outcome of the test might determine what diet you recommend (positive or negative for the APOC3 and APOA1 SNPs)?
4: Find a research study that examined existing genetic variations in an effort to develop a personalized nutrition intervention for at least one symptom related to metabolic syndrome. In approximately 100-200 words, describe the genetic variation and how it affects the way a patient may respond to a nutrition intervention. What were the significant findings of the study (if any)? How might you use this information in your future practice?
5: The National Institutes of Health and other funding agencies are now requiring researchers to consider biological sex in their study design. You are a researcher studying dietary interventions. If you include both males and females in your upcoming study design, it will cost twice as much and take twice as long to conduct the study. Do you really need to include both males and females? I mean, they can’t be that different in their response to a dietary intervention…can they?
