Abstract

This study was designed to assess the effects of long-term adaptation to a high protein diet on energy intake, body weight gain, body composition and splanchnic metabolic indicators in rats. For this purpose, adult male Wistar rats were fed either a 50 g/100 g dry matter (DM) protein diet (P50 group) or a 14 g/100 g DM protein diet (P14 group) for 21 d. These two groups were compared with a P14 pair-fed (P14-pf) group that consumed the same daily energy as the P50 group. The energy intake of the P50 group was 16 +/- 1% less than that of the P14 group (P < 0.05), and the P50 group had significantly lower body weight. The P50 group had significantly less adipose tissue compared with both P14 and P14-pf rats. The activities of the brush border membrane enzymes, neutral aminopeptidase and gamma-glutamyl transferase, were significantly higher in the P50 group than in the P14 rats. Similarly, the activities of alanine aminotransferase, arginase and serine dehydratase were significantly higher in the liver of P50 rats compared with P14 rats. Both amino acid transporter system A and X(A,G-) activities, measured in freshly isolated hepatocytes, were significantly higher in the P50 group (8- and 1.5-fold, P < 0.05, respectively) compared with the P14 group. The 1.5-fold increase in the steady-state activity of X(A,G-) was accompanied by a doubling of EAAT2 mRNA, involved in the system X(A,G-). This study provides confirmation that specific biochemical and molecular adaptive processes of the splanchnic area are involved in the response to variations in the protein content of the diet.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Some studies suggest that rats will consume and grow rather well on high-protein diets if given sufficient time to adapt to the diet.

    “some studies suggest that rats will consume and grow rather well on high-protein diets if given sufficient time to adapt to the diet”
  • Control animals fed a high-protein diet exhibited decreased body weight gain, food intake, and other body composition parameters compared with control animals fed normal diet.

    “As expected (42), control animals fed a high-protein diet (Fig. 5C, D) exhibited decreased body weight gain, food intake, and other body composition parameters compared with control animals fed normal diet (Fig. 5A, B).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
