I'm a little hazy this morning. Can you clarify that?
United States Department of Agriculture:

43% of participants are white; 33% are African-American, non-Hispanic; 19% are Hispanic; 2% are Asian, 2% are Native American, and 1% are of unknown race or ethnicity.
Couldn’t find the direct link off wikipedia but there are other studies that bare this out.
It makes since whites are a large proportion of the population.
