Hidden hunger: micronutrient deficiencies

Summary

This narrative review by Biesalski (2013), published in Food & Nutrition Research, addresses the concept of 'hidden hunger' — a form of malnutrition characterised by inadequate intake or absorption of essential micronutrients despite sufficient caloric consumption. The paper likely synthesises evidence on the global burden of micronutrient deficiencies, identifying vulnerable populations and the dietary and food system factors that drive inadequate micronutrient status. It is likely to discuss implications for public health policy, food fortification, and dietary diversification strategies.

UK applicability

Although hidden hunger is most acute in low- and middle-income countries, the findings are broadly applicable to the UK context, where micronutrient inadequacies — particularly vitamin D, iron, iodine, and selenium — remain a recognised public health concern, especially among women of reproductive age, older adults, and those following restrictive diets.

Key measures

Prevalence of micronutrient deficiency (population estimates); affected nutrients (e.g. iron, zinc, vitamin A, iodine); associated health outcomes

Outcomes reported

The paper likely examines the prevalence, causes, and consequences of micronutrient deficiencies — particularly vitamins and minerals — affecting populations who consume sufficient calories but inadequate micronutrients. It probably reports on the scale of hidden hunger and its links to poor health outcomes, impaired development, and reduced immune function.
