Behaviour and hormonal status in healthy rats on a diet rich in Maillard reaction products with or without solvent extractable aroma compounds

► Effects of aroma-rich/aroma-poor Maillard-reaction products-rich diets (MRPD). ► In the rats, aroma-rich MRPD affects behaviour. ► MRPD alters glucose control, the expression of the insulin receptor (olfactory bulb). ► Aroma-rich-MRPD alters leptinemia, adiponectinemia, leptin receptor expression. ► Aroma-rich- MRPD affects central regulation of food intake and energy homeostasis.
