The dangerous role of posterior serum albumin concentration on glycemic control may be due to the fact that higher serum albumin tends to reflect overnutrition [20], and the most direct outcome of overnutrition is obesity, which is an independent risk factor for the development of the metabolic syndrome and diabetes [21, 22]; therefore, higher serum albumin concentration may cause elevated blood glucose concentration. This evidence concerns the gene ALB and overnutrition.
