Nutrition improves learning and memory in schoolchildren

10.10.2007
A team of European scientists from Unilever together with colleagues from research institutes in Australia and Indonesia have demonstrated that nutrition can improve verbal learning and memory in schoolchildren.

In a 12 month study of 780 children in Australia and Indonesia, published in the American Journal of Clinical Nutrition, the researchers assessed the effects of adding a specific vitamin and mineral mix to a daily drink.

In Australia, children that received the daily drink with the added vitamin and mineral mix performed significantly better on mental performance tests than children in a control group that received the drink without added nutrients. In Indonesia a similar trend was observed, but only in the girls.

This study confirms that nutrition can positively influence cognitive development in schoolchildren, even in western children who are well-fed.

The scientists studied 396 well-nourished children in Australia and 384 poorly nourished children in Indonesia. In each country, the children were randomly allocated to one of four groups, receiving a drink with either a mix of micronutrients (iron, zinc, folate and vitamins A, B-6, B-12 and C) or with fish-oil (DHA and EPA), or with both added, or with nothing added (placebo).

After twelve months, children in Australia who received the drink with the nutrient mix showed higher blood levels of these micronutrients, which means that their bodies were taking up the nutrients. In addition, they performed significantly better on tests measuring their learning and memory capabilities compared to children in the other groups. A similar trend was observed in Indonesia, but only in the girls. The addition of fish oil to the fortified drink did not conclusively show any additional effects on cognition.

This study adds to the mounting evidence that nutrition plays an important role in mental development in children. Previously, deficiencies in iron and iodine have been linked to impaired cognitive development in young children; there is also emerging evidence that deficiencies in zinc, folate and vitamin B12 compromise mental development in children. More recently, fish oils (EPA, DHA) have also been linked to child cognitive development.

Most studies to date have focused on deficiencies in single nutrients in young age groups. Yet the brain continues to grow and develop during childhood and adolescence. Little is known about the role of nutrition for mental development after the age of 2, nor have many studies looked at the effect of offering a mix of nutrients. Until this study, there were very few randomized controlled intervention studies assessing the impact of a multiple-micronutrient intervention on cognitive function in schoolchildren.

This study confirms that nutrition can positively influence cognitive development in schoolchildren, even in children who are well-fed. The researchers suggest that this finding could be relevant across the western world.

The investigators recommend further research to investigate the exact role of DHA and EPA in healthy school-aged children. Another research focus is the further optimisation of cognitive development tests with respect to their validity and sensitivity across cultures. The scientists suggest that the smaller effects of the vitamins and minerals in Indonesia could be a result of a lower sensitivity of the cognitive tests in that country.

This study was performed by the NEMO study group (Nutrition Enhancement for Mental Optimization), which consists of the Unilever Food and Health Research Institute (Vlaardingen, The Netherlands); CSIRO, Human Nutrition (Adelaide, Australia) and the SEAMEO-TROPMED Regional Center for Community Nutrition, University of Indonesia (Jakarta Pusat, Indonesia).

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
