Paleo diet linked to heart disease risk. A new study shows that people who follow the Paleolithic, or Paleo, diet are at risk of developing heart disease.
A Paleo diet includes fruits, vegetables, nuts, and seeds, lean meats, especially grass-fed animals, omega-3 fatty acids, whole grains, and legumes, oils from fruits and nuts.
One research has found that the Paleo diet could reduce the risk of heart attacks and cardiovascular disease.
However, another study shows that this diet led to unhealthful weight gain as well as associated with risk of diabetes and cardiovascular problems.
Now a recent study has found that people who follow Paleo diets have high levels of a blood biomarker tied to heart disease risk. The researchers have published their findings in the European Journal of Nutrition.
The team looked at 44 participants who followed Paleo diets, and 47 participants who ate usual diets. The researchers collected the participants’ biological samples, analyzed their diets over a year. Then, they compared the data of the Paleo cohort with the control group.
Their analysis found increased blood levels of a compound which was associated with heart disease (trimethylamine N-oxide) across Paleo groups.
“Many Paleo diet proponents claim the diet is beneficial to gut health, but this research suggests that, when it comes to the production of trimethylamine N-oxide in the gut, the Paleo diet could be having an adverse impact in terms of heart health,” said Angela Genoni, Ph.D., who led this new study.
