 This study will be conducted in type 2 diabetic patients to evaluate the if there is a different response of serum lipids after a standard meal rich in saturated fatty acids in patients who have the presence of a genetic alteration. This alteration that will be evaluated is a polymorphism, change of an amino acid in the gene of FABP2. This gene that can influence the absorption of lipids in the intestine and subjects who have the altered genotype presence of T allele can have an abnormal lipid profile as compared to subjects without this genotype.
