The relation between dietary phytochemical index and metabolic syndrome and its components in a large sample of Iranian adults: a population-based study

Dietary phytochemicals have been shown to have a protective effect against chronic diseases, however the association with the metabolic syndrome (MetS) has not yet been investigated.

This recent study investigates the Dietary Phytochemical Index (DPI), based on daily dietary energy (kcal) derived from phytochemical rich foods, in association with the odds ratio of MetS and its components.

 Quick takes:

  • The prevalence of MetS is affected by various factors including race, age, gender, lifestyle, diet, genetics, and history of diabetes, hypertension and CVD
  • Previous studies focused on nutrients, foods, and food groups; however, new approaches in nutritional studies take dietary patterns into consideration
  • Phytochemicals are natural bioactive compounds that have been shown to have health boosting effects due to their antioxidant and anti-inflammatory properties, and their protective effects against the development of insulin resistance, abnormal glucose and lipid levels, and abdominal obesity
  • Results from this study show a lower risk of MetS associated with higher DPI scores in a large sample of Iranian women
  • High DPI scores were also associated with lower odds ratio of individual components of MetS
  • Consumption of foods high in DPI could reduce the odds of MetS and its components, especially in women
