This one found no differences in the postprandial rise in muscle protein synthesis rates following ingestion of 30g protein provided either as cheese or as milk protein at rest or during recovery from exercise in healthy, young males.
- The study compared the impact of ingesting 30g protein provided in the form of cheese or milk protein concentrate on postprandial muscle protein synthesis rates in vivo in 20 healthy, young males.
- An increase in circulating amino acid concentrations following the ingestion of 30g protein provided either as cheese or milk protein was observed.
- The early postprandial rise in circulating amino acids was attenuated, but subsequently more sustained following cheese compared with milk protein ingestion.
- Muscle protein synthesis rates increased substantially following both cheese and milk protein ingestion, with greater increases observed when exercise was performed prior to protein ingestion.
- No differences were observed in postprandial muscle protein synthesis rates at rest or during recovery from exercise following cheese compared with milk protein ingestion.
- "Our data further support the understanding that the food matrix in which protein is provided strongly affects protein digestion and amino acid absorption, and modulates the subsequent postprandial plasma amino acid profile"
- "Clearly, the cheese matrix did not compromise the muscle protein synthetic response, despite the attenuated postprandial rise in circulating plasma amino acid concentrations...
"...We speculate that this may also be attributed to the more sustained elevation of plasma amino acid availability following cheese ingestion when compared with the milk protein concentrate."
- "The present data extend on previous work on the anabolic properties of dairy protein isolates and concentrates...
"...and suggest that previous findings on the postprandial stimulation of muscle protein synthesis following the ingestion of ample amounts of dairy protein concentrates also apply to the consumption of dairy whole foods...
"...Clearly, (dairy) whole foods, that are typically consumed as part of our diet, provide strong stimuli for muscle protein synthesis....
"...These observations were evident both at rest and during recovery from exercise...
"...showing that the use of protein isolates or concentrates does not necessarily provide any surplus benefits over the consumption of protein-dense whole foods when trying to augment muscle mass accretion."
Cheese Ingestion Increases Muscle Protein Synthesis Rates Both at Rest and During Recovery from Exercise in Healthy, Young Males: A Randomized Parallel-Group Trial (open access)
This one not only brings forth evidence that challenges the current crossover concept, it also suggests that low-carb diets may also reverse features of pre-diabetes and future metabolic disease risk.
- The article (mostly) used data from these two papers:
- The data from these studies sheds doubt to the popular concept that human athletes are unable to extract any meaningful degree of energy from fat oxidation during exercise at intensities >85%VO2max.
In this one, high intakes of seafood, and particularly small fish rich in n-3 fatty acids, was associated with a lower risk of 10-year fatal and non-fatal cardiovascular disease risk in Greek adults with a mean age of 45.2 years.
- Less than one-10th of the study participants consumed >1 serving of small fish rich in n-3 fatty acids per week.
- Participants who consumed >2 servings per week of seafood had at least 27% decreased risk of developing CVD and 74% lower 10-year risk of dying due to CVD.
Interestingly, using NMR spectroscopy, this one suggests that newly manifest type 2 diabetes-associated dyslipoproteinemia does not significantly change the total concentrations of the lipoproteins produced in the liver, but selectively their subclass distributions.
- In the present study, German long time blood donors that were assumed to be healthy according to the rules applying for blood donors were examined.
Impaired fasting glucose, impaired glucose tolerance or manifest type 2 diabetes were not known for this group before they were included in this study.
In this one, 3 isocaloric meals with different macronutrient compositions showed different postprandial metabolic profiles, with postprandial exercise altered substrate oxidation and preventing hyperglycemia induced by an high-carbohydrate meal.
- The study aimed to assess the collective effects of 3 isocaloric meals: higher in carbohydrate (74.2% energy), fat (64.6% energy), or protein (39.5% energy) on energy expenditure and clinical and metabolomic biomarkers in men with normal weight or overweight/obesity.
- The 3 isocaloric diets varying in macronutrients showed distinctive postprandial metabolic profiles, while exercise altered substrate oxidation and inhibited the hyperglycemia induced by the higher-carbohydrate meal.
This systematic overview suggests that the literature overall confirms the existence of the physical activity paradox in healthcare workers.
- The physical activity paradox states that even though leisure-time (particularly moderate-to-vigorous) physical activity promotes health, more relative time spent on (particularly moderate-to-vigorous) physical activity during work seems to impair health.
- This systematic overview found that, in healthcare workers, occupational physical activity is primarily conducted at light to moderate-intensity and leisure-time physical activity at light- to high intensity.
In this one, a phenotype-tailored lifestyle intervention was associated with further improvements in measures of body composition and triglycerides compared with a standard lifestyle intervention.
- This 12-week, single-centre non-randomised proof-of-concept clinical trial included men and women aged 18–65 years with a body mass index (BMI) greater than 30 without history of any bariatric procedure, and current use of any medication known to affect weight.
- Participants were assigned to their intervention based on their period of enrollment.
