Data from a three-country survey seeking to understand beliefs of adults on the role of diet for optimal health, as well as consumption of key micronutrients including Omega-3 and Vitamin D, will be published in the November/December issue of Nutrition Today. The survey of 3,000 American, British and German adults found that 72 percent reported having a "healthy" or "optimal" diet and more than half (52 percent) believed they consume all the key nutrients needed for optimal nutrition through food sources alone. However, the prevalence of chronic diseases in these countries suggests respondents may be overestimating how healthy their diets are. While research indicates that Omega-3s can provide a beneficial advantage for those predisposed to cardiovascular diseases , it remains the leading cause of death in the U.S., U.K. and Germany. The survey was commissioned by the Global Nutrition and Health Alliance (GNHA).

"Regardless of country, most consumers know optimal nutrition is important. A nutrient rich diet is the foundation for a healthy life," said GNHA founding member Suzanne Steinbaum, DO, Director & Attending Cardiologist, Women and Heart Disease Center, Lenox Hill Hospital. "Omega-3s are proven to be beneficial for cardiovascular health, as well as cognitive function, but far too often, people do not consume the amount needed for the greatest benefit. That is why I recommend all my patients take an Omega-3 supplement."

In terms of supplementation of Omega-3 and Vitamin D, the survey also found that less than a third (32 percent) of those polled were actively taking a supplement.

"Preaching about proper diet is not enough. Perceptions of a healthy diet and the fact that it is very difficult to consume the recommended intake of nutrients such as Omega-3 and Vitamin D via diet alone, require us to rethink that approach," said GNHA founding member Nigel Denby, RD, Head of Dietetics at Grub4Life in London. "Additional studies are needed to demonstrate the truth behind what people report they are consuming and what they really are eating. These types of studies would help further discussion about the role of vitamin and mineral supplementation as part of a healthy diet."
