In general terms, this work, locate the trends identified in the 1989-2008 period, in relation to variables such as per capita income and food consumption. It is concluded, that during the years that elapse between 1989 and 2003 the food social programs failed to stop the deterioration of the caloric intake that occurred as a result of the fall in the purchasing power of specifically line feed, which was associated with the reform process and against reform, and prolongs the tendency towards the deterioration of the caloric intake that develops after 1981, as part of the collapse of world ranking capitalism and the country. In the subperiod 2004-2008, there is an increase in intake and food access caused by the oil boom levels and food and social policies that were in this context, which does not seem to be sustainable in a scenario of lower prices of oil and of a market economy in general extremely unstable.
