How many countries have hunger levels under alarming?

The 2012 Global Hunger Index says hunger remains a serious problem worldwide, with alarming levels in some countries. The Index links hunger to the unsustainable use of land, water and energy resources.
    (23)The Global Hunger Index says 17 countries have hunger levels described as alarming, while three others are listed as extremely alarming—namely, Burundi, Eritrea and Haiti. Despite the situation in the two African countries, the Index says the sub-Saharan region has made progress against hunger over the last 5 to 10 years. South Asia, on the other hand, has made little progress during that same period, despite having done well in the 1990s.
