One of the limitations for small-to medium-sized food companies to prove efcacy of functional foods, or novel diets, is the cost of human clinical trials. Most new functional foods are developed based on a prior hypothesis. However, the food or dietary context may negate such hypotheses being correct. Thus, a costly human trial, of the standard necessary for a health claim, may fail to prove the desired effect of the new food. A variant of nutrigenomics, which is food or diet-focused, is sometimes being described as foodomics [1]. It enables non-hypothesis-based establishment of appropriate biomarkers to help reduce the test time and increase the efcacy of establishing the quickest and most effective test methods to move directly to a health claim. We have tested the ability of this approach to prove the human efcacy and to derive insights into the mechanism of action of a modied diet, in a proof of principle study in Auckland, New Zealand.
