Global map identifying areas with different omega-3 levels

 
 
 

A recent research has created a global map identifying countries and regions with different blood levels of EPA and DHA. Data come from 298 studies of healthy adults, published in 1980 or later. The outcomes reveal considerable variability in blood levels of EPA + DHA, and also show that EPA + DHA blood levels are in the very low to low range for most of the world. This late is of concern, since may increase global risk for chronic disease.

Regions with high blood levels of EPA + DHA (more than 8%) were found in:

  • Regions with countries on the Sea of Japan (Japan, South Korea, and Primorsrky Krai, a region of Russia).
  • Scandinavia (Denmark, Norway, and Greenland).
  • Regions with populations that are not fully adapted to Western diet (Northern Russia, Alaska, Greenland, Papua New Guinea, Fiji, Nigeria, and the St. Helena Bay region of South Africa).

Moderate blood levels of EPA + DHA were observed in:

  • Northern Canada (Cree/Inuit populations), Chile, Iceland, Finland, Sweden, Tunisia, Hong Kong, Mongolia and French Polynesia.

And low blood levels of EPA + DHA in:

  • Eight European countries (Belgium, Czech Republic, France, Germany, Scotland, Spain, and The Netherlands).
  • Countries from the middle East (Israel), Asia (China, Russia, and Singapore), Oceania (Australia and New Zealand) and Africa (South Africa and Tanzania).

Very low blood levels of EPA + DHA (4% or less) were observed in:

  • North America (Canada and United States of America), Central and South America (Guatemala and Brazil), Europe (Ireland, United Kingdom, Italy, Greece, Serbia, and Turkey), the Middle East (Iran and Bahrain), Southeast Asia (India) and Africa (Kenya).

Data was not found for most of Africa, Eastern Europe, the Middle East and Central Asia, Southeast Asia, and Central and South America.

Global blood levels of EPA + DHA are low as a result of intakes lower than expert group recommendations.
