Companies are jumping on the nutrigenomics bandwagon – the emerging science of how nutrition interacts with your individual DNA.
Every time Rebecca Castle sat down to eat her favorite food, she says she suffered excruciating abdominal pain.
…
That pain went on for more than two years. Castle saw multiple doctors and then took a saliva DNA metabolic test.“I was allergic to starch,” she said. “That’s mostly root vegetables, corn, peas, sweet potatoes.”
Ahmed El-Sohemy is the chief scientific officer at Nutrigenomix. “Individual genetic differences can help us understand why some people respond differently from others,” El-Sohemy said. Nutrigenomix says their DNA test looks at a person’s 45 genetic markers. The company makes recommendations based on the patient’s genetic profile, pointing out attributes like “an elevated risk for low iron.”
…
“DNA tests for diet and exercise just are not validated,” [said Dr. David Agus, a CBS News contributor.] “There are very few of them that actually have data behind them.”
…
There is a kernel of science behind the interaction of nutrition and genetics. But the ability to use your own genome to predict how you will respond to specific nutrients – that science is not there yet.
