Nutrition Tips : Nutrigenomics

My name is Christine Marquette and I’m a registered
dietitian and I’m going to talk to you about what is nutrigenomics. Nutrigenomics is a
fairly new field that’s the study of nutrition and the impact on genes. The interaction between
the two. There’s been a lot of potential in determining that different nutrients and different
foods can really impact your gene expression. By the same token, depending on your genotype,
your body may respond in different ways to different nutrients. This has a lot of potential
for enabling us to actually determine diets to prevent or to mitigate or to even cure
potential diseases. So for example some of the early research that has already been done,
has identified different types of genes that respond differently to fats. So for example
if a person has genotype A, they actually may be able to tolerate a slightly higher
level of saturated fat without it having a negative impact on their LDL cholesterol.
Whereas a person with genotype B, they need a much lower level of saturated fat in their
diet because if they eat above that amount, it significantly increases their LDL cholesterol.
So this is just one example of research that we already have that shows the impact of your
genotype and your foods that you’re taking in and how it affects your overall health
and the outcomes. So there’s a lot of potential in developing ways of eating, developing particular
diet plans that can help treat or possibly even cure a myriad of health conditions.
