The incidence of obesity and type 2 diabetes mellitus (T2DM) is increasing, and new experimental models are required to investigate the diverse aspects of these polygenic diseases, which are intimately linked in terms of aetiology. Feline T2DM has been shown to closely resemble human T2DM in terms of its clinical, pathological and physiological features. Our aim was to develop a feline model of diet-induced weight gain, adiposity and metabolic deregulation, and to examine correlates of weight and body fat change, insulin homeostasis, lipid profile, adipokines and clinical chemistry, in order to study associations which may shed light on the mechanism of diet-induced metabolic dysregulation. We used a combination of partially hydrogenated vegetable shortening and high-fructose corn syrup to generate a high-fat–high-fructose diet. The effects of this diet were compared with an isoenergetic standard chow, either in the presence or absence of 1·125 % dietary monosodium glutamate (MSG). Dual-energy X-ray absorptiometry body imaging and a glucose tolerance test were performed. The present results indicate that dietary MSG increased weight gain and adiposity, and reduced insulin sensitivity (P < 0·05), whereas high-fat–high-fructose feeding resulted in elevated cortisol and markers of liver dysfunction (P < 0·01). The combination of all three dietary constituents resulted in lower insulin levels and elevated serum β-hydroxybutyrate and cortisol (P < 0·05). This combination also resulted in a lower first-phase insulin release during glucose tolerance testing (P < 0·001). In conclusion, markers of insulin deregulation and metabolic dysfunction associated with adiposity and T2DM can be induced by dietary factors in a feline model.

Mangifera indica seed kernel was assessed for antinutirent content and effects on serum lipid profile of monosodium glutamate-challenged rats. Group A rats received 8000 mg/kg body weight, b.w of monosodium glutamate (MSG). Group B rats received the sample extract (300 mg/kg b.w). Group C rats were sham-administered distilled water. Groups D and E rats received 8000 mg/kg b.w of MSG in addition to 200 and 400 mg/kg b.w, respectively of sample extract. Tannin (29.21±5.39 mg/100 g) was highest (p<0.05) while phytate (0.38±0.02 mg/100g) was least. After fourteen days daily oral exposure, MSG-exposed rats had higher (p<0.05) total cholesterol (CHOL), triacylglycerol (TAG) and low density lipoprotein (LDL) but lower (p<0.05) high density lipoprotein (HDL) concentration compared to rats in the other groups. MSG-intoxicated rats co-treated respectively with 200 and 400 mg/kg b.w of the extract had dose dependent reduction (p<0.05) compared to the corresponding effects in non-extract-co-treated MSG-intoxicated rats. Compared to others, rats in the Extract group had higher (p<0.05) CHOL: TAG but lower (p<0.05) TAG:CHOL ratios while rats in the MSG-group had higher (p<0.05) HDL:LDL but lower (p<0.05) LDL:HDL ratios. Results demonstrated the preponderance of tannin in, and significant serum lipid lowering potential in normal and MSG-challenged rats of, the sample. Studies using antinutrient-process-reduced sample in hyperlipidemia-related health-challenged models and collaborating the suggested implication of lipid-profile-component-ratios are warranted and recommended.
