Can we rely on the newest field in nutrition science to lead us to better health? The field of nutrigenomics (how our diet choices affect our health) promises us these benefits. So, are these claims valid?
The following article discusses this possibility. Research has suggested that genetic testing may provide slight benefits, but this evidence is weak. Another thought is that in our current food environment, the biggest beneficiaries may be the food and supplement industry and will take this opportunity to create and sell, for example, breakfast cereals and diet supplements touted to prevent certain diseases. But we still need the science to back up these claims. Another aspect is that food is not just about health but also about pleasure, culture, sociability, identify, and beliefs.
Some day we may be able to have our genes analyzed and have specific foods and dietary supplements prescribed to prevent diseases. By then our knowledge of the gene/diet interaction may be accurate enough to predict our chance of chronic disease. But until then, save your money or don’t take the results too seriously (my opinion).
