由營(yíng)養(yǎng)不良造成的醫(yī)學(xué)問(wèn)題稱作營(yíng)養(yǎng)缺乏癥。這些疾病是由于蛋白質(zhì)、維他命、礦物質(zhì)及食物中的營(yíng)養(yǎng)素的缺乏引發(fā)的。這種現(xiàn)象多發(fā)生于發(fā)展中國(guó)家及不發(fā)達(dá)國(guó)家。

如今兒童營(yíng)養(yǎng)不良癥已被意識(shí)到。我們應(yīng)照顧好兒童，使他們得到充足合理的食物。這樣我們就可以控制這種疾病。以下國(guó)家都有五百萬(wàn)以上的人口患有營(yíng)養(yǎng)不良癥：印度、中國(guó)、孟加拉國(guó)、印度尼西亞、肯尼亞、哥倫比亞。
