Humans Possess Surprising Nutritional Intelligence

Humans possess surprising nutritional intelligence:

The international study, led by the University of Bristol (UK), set out to re-examine and test the widely-held view that humans evolved to favour energy dense foods and our diets are balanced simply by eating a variety of different foods. Contrary to this belief, its findings revealed people seem to have "nutritional wisdom," whereby foods are selected in part to meet our need for vitamins and minerals and avoid nutritional deficiencies.

Lead author Jeff Brunstrom, Professor of Experimental Psychology, said: "The results of our studies are hugely significant and rather surprising. For the first time in almost a century, we've shown humans are more sophisticated in their food choices, and appear to select based on specific micronutrients rather than simply eating everything and getting what they need by default."

The paper, published in the journal Appetite, gives renewed weight to bold research carried out in the 1930s by an American paediatrician, Dr Clara Davis, who put a group of 15 babies on a diet which allowed them to "self-select", in other words eat whatever they wanted, from 33 different food items. While no child ate the same combination of foods, they all achieved and maintained a good state of health, which was taken as evidence of "nutritional wisdom."
