Background: We planned to evaluate the effects of different enteral nutrients on the levels of serum leptin, protein and albumin changes and also to compare their effects on mucosal morphology of small intestine.
Methods: Rats were randomly divided into 5 groups each including 10 animals. Group I rats were given rat chow and water. Group II rats were fed with standard enteral nutrient. Group III rats were fed with calorie enriched enteral nutrient. Group IV rats were given enteral nutrition supplemented with fiber. Group V rats were fed with immunonutrient. Serum albumin, protein, leptin levels were measured. Terminal ileum of each rat was scored.
Results: We found no difference in serum leptin, protein and albumin levels. The average mucosal atrophy of rats fed with standard chow was significantly different than that of rats fed with standard and calorie enriched nutrients. Feeding with nutrients supplemented with fiber and immunonutrient did not cause significant distortion in mucosal integrity when compared with feeding with standard chow.
Conclusion: Low levels of leptin may show malnutrition but for determination of nutritional status of a patient receiving enteral nutrition, studies with long duration are required.

Objective: The current study was conducted to investigate the effect of intermittent fasting (IF) with a low-carbohydrate-high-protein (LCHP) diet on blood glucose control in streptozotocin (STZ)-nicotinamide-induced type 2 diabetic rats (DR).
Methods: Thirty male Wistar rats were divided into six groups ( = 5) including a group of normal rats (NR) that received a control diet (CD) (50% carbohydrates, 17% protein, and 33% fat) with (AL) feeding. The remaining 5 groups were DR injected with STZ and fed on CD or LCHP diet (40% carbohydrates, 30% protein, and 30% fat) for 6 weeks, either AL or IF (with a time-restricted feeding of 16 h followed by 8 h feeding period).

Magnesium (Mg) is a mineral necessary for many biological activities in mammals. Here, we compared the effect of two Mg compounds [Mg picolinate (MgPic) to Mg oxide (MgO)] on Mg bioavailability and intestinal Mg and calcium transporter protein levels. Three groups of 21 male Wistar-Albino rats were randomly allocated and fed a standard diet (control) or a 500 mg/kg Mg-supplemented (MgPic or MgO) diet for 8 weeks.

The enhanced bioavailability of quercetin (Qr), which has low absorption, may have beneficial effects on human health. This study aimed to elucidate the effects of simultaneous pectin ingestion on the absorption and antioxidant activity of Qr. Qr concentrations in the plasma and urine of rats fed Qr + cellulose or Qr + pectin diets were determined, and thiobarbituric acid reactive substances (TBARS) in oxidized low-density lipoprotein (LDL) were measured.

The prevalence of obesity increases yearly in the world. The traditional local diet of the Western Regions of Cameroon was suspected to be the main contributor to the high prevalence of obesity in these Regions. This study aimed to evaluate the effects of a Cameroon-comparable fat diet on visceral obesity in rats.
