<strong>Milk</strong> <strong>and</strong> dairy products <strong>in</strong> human nutrition<br />
(MDG 1c) is with<strong>in</strong> reach, although many challenges rema<strong>in</strong> <strong>and</strong> accelerated action<br />
is needed to cont<strong>in</strong>ue this positive trend.<br />
1.2.2 Childhood undernutrition<br />
While undernourishment has been decl<strong>in</strong><strong>in</strong>g there have also been improvements <strong>in</strong><br />
child nutritional status as expressed by the key anthropometric <strong>in</strong>dicators of child<br />
stunt<strong>in</strong>g, underweight, wast<strong>in</strong>g <strong>and</strong> nutrition-related child mortality. Nevertheless,<br />
the rate of improvement suggest that we are unlikely to meet the United Nations’<br />
goal of halv<strong>in</strong>g the 1990 underweight prevalence levels on a global level or <strong>in</strong> all<br />
develop<strong>in</strong>g countries.<br />
New estimates show that globally 165 million children under five years of age,<br />
or 26 percent of all children, were stunted (low height-for-age) <strong>in</strong> 2011, a 35 percent<br />
decrease from an estimated 253 million <strong>in</strong> 1990 (UNICEF, WHO <strong>and</strong> World Bank,<br />
2012). Despite improvements, high prevalence of stunt<strong>in</strong>g rema<strong>in</strong>s a major problem,<br />
especially <strong>in</strong> Africa <strong>and</strong> South Asia where 90 percent of the world’s stunted children<br />
reside. Stunt<strong>in</strong>g reflects the cumulative effects of poor maternal nutrition, poor diet<br />
<strong>and</strong> <strong>in</strong>fections dur<strong>in</strong>g the first two years of life. It results <strong>in</strong> slowed child growth <strong>and</strong><br />
impedes bra<strong>in</strong> development; it often goes unrecognized <strong>and</strong> is largely irreversible.<br />
Adequate dietary <strong>in</strong>take is especially critical <strong>in</strong> the period from 6 to 18 months of a<br />
child’s life when a child’s growth rate is high. At six months, breastmilk alone is no<br />
longer adequate to support normal growth <strong>and</strong> mental development <strong>and</strong> nutrientrich<br />
complementary foods must be <strong>in</strong>troduced, <strong>in</strong>clud<strong>in</strong>g animal-source foods.<br />
There has also been a decl<strong>in</strong>e <strong>in</strong> the prevalence of underweight (low weight-forheight)<br />
globally, with an estimated 101 million children under five years of age, or<br />
16 percent of all children, underweight <strong>in</strong> 2011, a 36 percent decrease from an estimated<br />
159 million <strong>in</strong> 1990 (UNICEF, WHO <strong>and</strong> World Bank, 2012). Underweight<br />
was selected as the <strong>in</strong>dicator to track progress towards the MDG target of reduc<strong>in</strong>g<br />
malnutrition by half by 2015. Children who have a low weight-for-age can either<br />
be wasted (low weight-for-height), stunted or both. Underweight is a composite<br />
<strong>in</strong>dicator <strong>and</strong> may therefore be difficult to <strong>in</strong>terpret.<br />
An estimated 52 million children under five years of age were wasted <strong>in</strong> 2011,<br />
represent<strong>in</strong>g an 11 percent decrease from an estimated 58 million <strong>in</strong> 1990. Latest<br />
estimates show that 70 percent of the world’s wasted children live <strong>in</strong> Asia, mostly<br />
<strong>in</strong> South Asia (UNICEF, WHO <strong>and</strong> World Bank, 2012). Wast<strong>in</strong>g results from acute<br />
nutritional deprivation, often comb<strong>in</strong>ed with <strong>in</strong>fection, <strong>and</strong> occurs especially dur<strong>in</strong>g<br />
periods of severe food shortages. Wasted children have a weak immune system <strong>and</strong><br />
are at <strong>in</strong>creased risk of severe acute malnutrition <strong>and</strong> death. F<strong>in</strong>d<strong>in</strong>gs show that<br />
childhood malnutrition is an underly<strong>in</strong>g cause of death <strong>in</strong> an estimated 35 percent<br />
of all deaths among children under the age of five years, <strong>in</strong>dicat<strong>in</strong>g that cont<strong>in</strong>u<strong>in</strong>g<br />
efforts to improve access to better quality diets <strong>and</strong> health are imperative (Black et<br />
al., 2008).<br />
1.2.3 Micronutrient malnutrition<br />
Access to better <strong>and</strong> more diversified diets is key for combat<strong>in</strong>g problems of micronutrient<br />
malnutrition or “hidden hunger”. Despite progress <strong>in</strong> address<strong>in</strong>g micronutrient<br />
malnutrition <strong>in</strong> some countries <strong>and</strong> regions, several billion adults <strong>and</strong> children<br />
cont<strong>in</strong>ue to be affected by one or more nutrient deficiencies (<strong>FAO</strong>, 2011). Although
