In the Philippines, one out of four children is considered underweight or stunted - telling signs of nutritional problems. But this figure, which translates into four million children under 10 being undernourished, is considered an improvement, according to the country's Food and Nutrition Research Institute (FNRI). In the early 1990s, 30 to 40 percent of the same age group were found to be either underweight, stunted or in a worse physical condition.
