The national food policy of Bangladesh says that food is a basic human need (..). John Aylieff of World Food Program (WFP) said: "First of all, hunger and malnutrition are probably the biggest impediments to economic growth in the world today. The economic cost of hunger is immense. It is estimated that $20 to $30 billion a year are lost in the world due to hunger and malnutrition. It means that $500 billion to $10 trillion are lost in productivity and income. So, an investment in malnutrition and hunger today is an investment in tomorrow's GDP."
