Blood Test Can Reveal Your Eating Habits !

Blood sample is the key source for diagnosing several diseases and conditions. It can also reveal simple things like what you’re eating!

In a study that appeared in the Journal of Nutrition, researchers reveal a method to measure adherence to diet using blood sample. Their findings suggested that it is possible to assess dietary compliance by measuring certain biomarkers in the blood.

For the study, researchers involved 154 participants who were advised to follow a healthy diet rich in berries, vegetables, fatty fish, canola oil and whole grains. Later, blood samples were collected from these participants and several blood biomarkers reflecting the consumption of different key components of the diet were assessed.
  • These biomarkers included:
  • Serum alpha linoleic acid as a biomarker of canola oil consumption
  • Plasma beta carotene as a biomarker for vegetable intake and
  • Plasma alkylresorcinols reflecting whole grain consumption
Researchers suggested that to investigate health effects of whole diets, measurement of multiple biomarkers is required to reflect the intake of different components of the diet. This way of assessing compliance may help to better detect changes in risk factors.
