Nuclear anomalies in exfoliated buccal cells in healthy and diabetic individuals and the impact of a dietary intervention.

This study aimed to compare the frequencies of nuclear anomalies in buccal cells between diabetic and non-diabetic individuals and to assess the impact of a 'healthy diet'-a cornerstone in the treatment of diabetes. Seventy-six diabetic and 21 non-diabetic individuals participated in this parallel, randomised, intervention trial. All participants received information about the importance of a healthy diet, while participants randomly assigned to the intervention group received additionally 300g of vegetables and 25ml of plant oil rich in polyunsaturated fatty acids (PUFA) per day for 8 weeks.
