The researchers looked at the bioavailability of micronutrients in products that are available to the public on supermarket shelves and were surprised at their discovery.

鈥淲e found that all the pulse products, like chickpea and lentil flours, were excellent sources of micronutrients,鈥� says Thi Diem Nguyen, a PhD candidate in the School of Agriculture, Food and Wine.

鈥淧articularly for zinc and iron nutrition, they outperformed cereal products like oat and wheat flours.鈥�

Food Standards Australia New Zealand recommends growers and food producers fortify products with zinc and iron to help prevent dietary deficiencies. Zinc and iron deficiencies can have harmful health consequences, especially for children and pregnant people.

Fortification of these nutrients in food can either be done by growers, through the use of fertilisers, or by adding them as ingredients, such as during the baking process for bread products.

鈥淭his fortification strategy aims to improve public health by increasing the availability of essential micronutrients in commonly consumed foods,鈥� says Dr Stephanie Watts-Fawkes, a group leader and Future Making Fellow at the Waite Research Institute.

鈥淥ur results indicated that pulse products, such as chickpea and lentil, are superior sources of protein and minerals, particularly of zinc and iron, with higher micronutrient bioavailability compared to the cereal products tested.

鈥淶inc and iron concentrations in cereal products like wheat and oat flour were lower than other products, suggesting that they may not meet the nutritional targets recommended by Food Standards Australia New Zealand.鈥�

Bioavailability of zinc and iron, which is the ability for the human body to extract the nutrients from food, is also affected by other elements present in the cereal crops.

鈥淣utrient absorption can be limited by co-existing antinutritional factors in cereal grain, like the presence of phytate,鈥� says Nguyen.

鈥淯nderstanding how bioavailability varies among different cereal grains and legumes can help improve dietary recommendations and fortification strategies, ultimately addressing global micronutrient deficiencies, particularly in vulnerable populations.鈥�

Nguyen says her group鈥檚 research, which is published in , offers useful information to help people manage their health.

鈥淚ndividuals at risk of micronutrient deficiencies could include more pulses in their meals, which are rich in protein, zinc and iron, and have high bioavailability,鈥� she says.

Dr Watts-Fawkes says her group will continue this research by looking into how to increase bioavailability of nutrients in crops.

鈥淲e would like to investigate ways to reduce phytates naturally, such as optimising cooking or processing methods; developing low-phytate, high-nutrient crops; and investigating how other micronutrients interact with phytates in cereals and pulses,鈥� she says.

The University of 新浪彩票 and the University of South Australia are joining forces to become Australia鈥檚 new major university 鈥� 新浪彩票 University.
