New study reveals lack of understanding around dietary deficiencies

A new survey has revealed the need for greater understanding of dietary deficiencies among Europeans and Americans.
The study, commissioned by the Global Nutrition and Health Alliance (GNHA), found that most adults believe their diets meet nutritional requirements, despite prevalence of diseases associated with deficiencies.
Data from the three-country study of America, Great Britain and Germany, which set out 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, found that 72 per cent reported having a healthy or optimal diet and more than half (52 per cent) believed they consume all the key nutrients needed for optimal nutrition through food sources alone.
Published in the journal Nutrition Today, the researchers reported that the prevalence of chronic diseases in these countries suggests respondents may be overestimating how healthy their diets are.
“Regardless of country, most consumers know optimal nutrition is important. A nutrient-rich diet is the foundation for a healthy life,” commented 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 found that less than a third (32 per cent) were actively taking a supplement.
Nigel Denby, RD, Head of Dietetics at Grub4Life, in London, and GNHA founding member, added: “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.
“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.”
