animal proteins; animals; body weight; diet; elderly; functional status; long term effects; men; muscle strength; physical activity; plant proteins; progeny; protein intake; risk; risk reduction; skeletal muscle; women
Abstract:
... Protein intake has been shown to lower risk of aging-related functional decline. The goal of this study was to assess long-term effects of weight-adjusted animal (AP) and plant protein (PP) intakes on aging-related change in functional status and grip strength. Framingham Offspring Study participants (n = 1896, 891 men and 1005 women), ≥age 50, were followed for an average of 14.4 years. Protein i ...

Abstract:
... BACKGROUND: Because a moderate-carbohydrate diet reportedly has minimal risks, the substitution of carbohydrate for protein has been emphasized. Few studies have explored the effect of moderate-carbohydrate diets with higher protein intake in Asians, who typically consume a high-carbohydrate low-fat diet. Therefore, this study evaluated the associations of moderate- versus high- carbohydrate diets ...

Abstract:
... Elevated plasma branched-chain amino acids (BCAA) and C3 and C5 acylcarnitines (AC) levels observed in individuals with insulin resistance (IR) might be influenced by dietary protein intakes. This study explores the associations between dietary protein sources, plasma BCAA levels and C3 and C5 ACs in normal weight (NW) or overweight (OW) individuals with or without metabolic syndrome (MS). Data fr ...

A recent review summarized the estimated average requirement (EAR) derived from IAAO plus two standard deviations as around 1.15–1.29 g/Kg body weight (BW) for elderlies. However, emerging evidence shows that providing protein beyond nitrogen balance point (as high as 1.5 g/Kg BW) to frail or ...

Abstract:
... Branched-chain amino acids (BCAAs) are elevated in the insulin-resistant (IR) state. The reasons for this increase remain unclear, but it may be related to abnormalities in BCAA metabolism and free fatty acid (FFA) metabolism. In this study, we quantified BCAA and FFA kinetics of IR and insulin-sensitive (IS) nonobese Asian men with the use of stable-isotope tracers. We hypothesized that in additi ...
