Humans may have more "Nutritional Intelligence" than their first thought ...

Pioneering research has permissive insights into what drives people''s basic food preferences, indicating that our choices might be smarter than previously thought and influenced by specific nutrients, rather than just calories, we need.

The research, led by the University of Bristol (UK), intends to re-examine and test the widely-held belief that humans evolved to favor energy-rich foods, and our diets were balanced simply by eating a variety of different foods. According to this belief, people seem to have nutritional wisdom, where foods are chosen in part to fulfill our need for vitamins and minerals and to avoid nutritional deficiencies.

According to the leading author, the results of our research are significant and rather surprising. For the first time in over a century, we have demonstrated that humans are more advanced in their food choices, rather than simply eating everything and getting what they require by default.

The study, published in the journalAppetite, will give a lot of focus to research done in the 1930s by an American pediatrician, Dr Clara Davis, who allowed a group of 15 babies to self-select and in other words eat whatever they desired, from 33 different foods. Despite their own accomplishments, all of the babies achieved and maintained a good health, which was taken as evidence of nutritional wisdom.

Its findings were later reviewed and criticized, but replicating Davis research was not possible because this form of experimentation on babies would today be considered unethical. As a result, anyone who has tried to find evidence for nutritional wisdom in humans has also found a faculty in other animals, such as sheep androdents.

To overcome these obstacles, the Professor Brunstroms team developed a novel technique which consisted in displaying people images of different fruit and vegetable pairings so their choices could be analysed without putting their health or wellbeing at jeopardy.

Two experiments led to the conclusion that people prefer certain food combinations more than others. For example, apple and banana varieties may be chosen less often than apple and blackberries. This indicates that the combined micronutrients appear to be predicted in a pair, and whether they may provide a balance of different micronutrients. To confirm this, they conducted a second experiment with different foods and rejected other explanations.

In order to complement and cross-check these findings, real-world meal combinations compared to those obtained by the UK National Diet and Nutrition Survey. Similarly, these surveys demonstrated that individuals combine meals in a way that increases their exposure to micronutrients in their diet. Particularly, components of popular UK meals, such as fish and chips or curry and rice, imply a wide range of micronutrients than meal combinations created randomly.

Mark Schatzker, a journalist and author, was honored at the annual meeting of the Society for the Study of Ingestive Behavior in Florida. In 2018, the two spoke, discussing how the flavour of whole foods and processed foods has altered, and what it has implications for health and well-being.

Interestingly, Professor Brunstrom''s and Mark Schatzkers research was based on a disagreement.

Mark presented a fascinating talk about how behavioural nutrition experts think that humans only really need calories. He pointed out, for example, that fine wine, rare spices, and wild mushrooms are highly sought after, but are a poor source of calories.

I went to see him at the end and thought I''d be okay. I think youre probably wrong. This marked the start of this wonderful journey, which eventually suggests I was wrong. When it comes to selecting a nutritious diet, humans seem to possess a lot of knowledge.

According to Mark Schatzker, research examines key issues particularly in today''s food environment. So, does our cultural fixation with fad diets, which limit or prohibit the use of certain foods, disrupt this dietary intelligence in ways we do not understand?

Animals are likely to use flavour as a guide to vitamins and minerals they need. We may be injecting junk foods such as potato chips and fizzy drinks with a false sheen of nutrition by adding flavourings to them. In other words, the food industry might alter its nutritional wisdom by removing harmful substances. We might also make us eat food we would normally avoid, thus reducing the obesity epidemic.
