According to the Daily NK on July 2, 2012:

World Food Programme reports during the month of July, North Koreans received only half the amount of recommended food, rations have been reduced down to half what they should be 300 grams per day.
Between drought and flood damage, crops have suffered and the distribution system is failing to meet the needs of the people.
Due to unrelenting poor weather condition this past July, North Korean food rations per person, already at the minimum recommended amount, were cut in half.
United Nations affiliated organization, the World Food Programme (WFP) recorded that from July 1st until the 15th, food distribution in North Korea was 370 grams per person per day, but during the second half of the month rations were reduced to a mere 300 grams, revealed a Voice of America broadcast two days ago. The World Food Programme puts the recommended amount of food per day at 600 grams minimum.
According to a North Korean based-WFP local official, rations consist of 20-30% rice and 70-80% corn. During the summer, barley, potatoes, wheat and other crops are included in the distribution.
From January until March, rations were maintained at 395 grams per person, and in April they were increased to 400 grams. In May, rations were reverted back to 395 grams and June again saw a slump, down to 380 grams per person.
The WFP attributes the decline in rations to various natural disasters, such as drought and flooding have led to extensive damage of cropland across North Korea.
The WFP estimates these ration shortages will continue to be severe until harvest time arrives in November.
To offer a context: 300 grams of food is roughly equivalent of about 2/3 a cup.
The below picture is a little dated in terms of what North Korea’s current food rationing is, but it offers a good comparison to the rest of the world.
