"Dietary protein intake" refers to the amount of protein that a person consumes through their diet. It represents the quantity of protein a person gets from the food they eat.
Full definition
Clearly, further study is required to assess the combined effects of negative energy balance and
dietary protein intake on cellular mechanisms contributing to the regulation of skeletal muscle mass.
Many experts and national organizations
recommend dietary protein intakes greater than the recommended allowance to maintain and promote muscle growth in older adults.
Because roughly 58 % of dietary protein appears in the blood as glucose, we can determine the amount of dietary protein that is required by looking
at dietary protein intakes and the amount of glucose that is produced.
Current guidelines recommend
restricting dietary protein intake to help manage CKD and slow progression to ESRD; however, there is limited evidence that overall dietary protein restriction or limiting specific food sources of protein intake may slow kidney function decline in the general population.
The discovery, reported in the American Journal of Clinical Nutrition, suggests that the widespread practice of throwing away egg yolks to maximize one's
dietary protein intake from eggs is counterproductive, said Nicholas Burd, a University of Illinois professor of kinesiology and community health who led the research.
We've showed an improvement in subjective sleep quality after higher
dietary protein intake during weight loss, which is intriguing and also emphasizes the need for more research with objective measurements of sleep to confirm our results.»
Despite
satisfactory dietary protein intake, as a consequence of inefficient digestion, absorption and / or assimilation, it is possible for the body to be amino - acid under - nourished at the cellular level.
To quote Layman again, he says: «During the last decade a growing body of research reveals that
dietary protein intakes above the RDA are beneficial in maintaining muscle function and mobility and in the treatment of diseases including obesity, osteoporosis, type 2 diabetes, Metabolic Syndrome, heart disease, and sarcopenia».
However,
doubling dietary protein intake (1.8 g · kg − 1 · d − 1) abrogated the increased nitrogen excretion and resultant negative nitrogen balance that occurred after the 7 - d energy deficit.
The overall calcium balance appears to be unchanged by
high dietary protein intake in healthy individuals (13), and current evidence suggests that increased protein intakes in those with adequate supplies of protein, calcium, and vitamin D do not adversely affect BMD or fracture risk (14).
Providing such an isocaloric supplement could lower
dietary protein intake in the control group, making a possible surplus benefit of protein supplementation less convincing.
When
your dietary protein intake is low or simply not - quite - there, BCAAs can be of invaluable help for preserving your hard - gained muscle mass and adding new pounds of lean muscle.
«the lowest level of
dietary protein intake that will balance the losses of nitrogen from the body, and thus maintain the body protein mass, in persons at energy balance with modest levels of physical activity.»

dietary protein intake and risk of hip fracture in postmenopausal women1, 2,3 Am J Clin Nutr January 1999 vol.
Dietary Protein Intake and Coronary Heart Disease in a Large Community Based Cohor: Results from the Atherosclerosis Risk in Communities (ARIC) Study.
Dietary protein intake and incidence of type 2 diabetes in Europe: the EPIC - InterAct Case - Cohort Study.
Dietary protein intake has received increased attention for its role in preventing cardiovascular disease, especially in relation to blood pressure — lowering effects.
«The determination of the anabolic response to
dietary protein intake at the muscle level is obviously important, since muscle is a major fate of essential amino acids (EAAs) absorbed from dietary protein.
Dietary protein intake and also individual amino acid status have been linked to psychological status in previously published studies.
Experimental models that use a variety of applied and basic molecular biological techniques to characterize the skeletal muscle proteolytic responses to manipulations in energy and
dietary protein intake are described.
However, increasing
dietary protein intake may offset the increase in nitrogen excretion and negative nitrogen balance that generally occurs during periods of energy deficiency (13, 14).
In that study, the extent of muscle loss in response to negative energy balance was proportional to
dietary protein intake.
