The future of nutrition research

There is little question that nutrition provides the foundation of health and wellbeing and that research into better nutrition is central to enabling a population live healthier, more productive, and longer lives.

With this perspective in mind, the American Society for Nutrition assembled a working group of leading nutrition thought leaders to identify a list of nutritional research areas that required greater or further analysis and prioritization.

In a symposium entitled "The Future of Nutrition Research" on Tuesday at Experimental Biology 2012 (#EB2012), these thought leaders outlined what was generally agreed as the six areas of nutrition research that deserved attention.

Could how much and often people eat depend on their genes?

Thanks to the Human Genome Project, we humans now know that we are all really very much the same at the level of our DNA. Our genomes are 99.9 percent identical, leaving really only 0.1 percent responsible for giving each of us what we would consider our differences or unique qualities. It's within this 0.1 percent that may also explain why some of us may be more likely to be overweight, obese, or susceptible to a disease such as type 2 diabetes.

One of the most promising developments in nutrition research are the insights provided by studies on how dietary components interact with genes. The knowledge gleaned could one day be used for reducing risk of disease and staying healthier, longer. This area of research is nutritional genomics, or nutrigenomics for short. Eventually understanding more about nutrigenomics could lead to our ability to better personalize our diet plans and make better food choices based on our genetic code.

Interestingly, however, new research suggests that it may be genes themselves that are guiding how much we eat as well as our food choices. The Genetic Subgroup of Look AHEAD and the Look AHEAD Research Group have recently reported findings in the American Journal of Clinical Nutrition that obesity-related gene sequences (loci) may affect how overweight or obese with type 2 diabetes consume food.
