Glucagon-like peptide-1 (GLP-1) is an incretin hormone released from intestinal L-cells in response to food entering into the gastrointestinal tract. GLP-1-based pharmaceuticals improve blood glucose regulation and reduce feeding. Specific macronutrients, when ingested, may trigger GLP-1 secretion and enhance the effects of systemic sitagliptin, a pharmacological inhibitor of DPP-IV (an enzyme that rapidly degrades GLP-1). In particular, macronutrient constituents found in dairy foods may act as potent secretagogues for GLP-1, and acute preclinical trials show that ingestion of dairy protein may represent a promising adjunct behavioral therapy in combination with sitagliptin...

While effects of the two classes of proteins found in milk (i.e. soluble proteins, including whey, and casein) on muscle protein synthesis have been well investigated after a single bout of resistance exercise (RE), the combined effects of these two proteins on the muscle responses to resistance training (RT) have not yet been investigated. Therefore, the aim of this study was to examine the effects of protein supplementation varying by the ratio between milk soluble proteins (fast-digested protein) and casein (slow-digested protein) on the muscle to a 9-week RT program...

Dudgeon, WD, Kelley, EP, and Scheett, TP. Effect of whey protein in conjunction with a caloric-restricted diet and resistance training. J Strength Cond Res 31(5): 1353-1361, 2017-Caloric-restricted weight loss, especially rapid weight loss, results from a decrease in both lean and fat mass (FM). The goal for many is to lose FM while retaining lean body mass (LBM) and muscular performance thus many turn to supplements. Sixteen resistance-trained men (24 ± 1.6 years of age) completed a 4 d·wk body building style split resistance training program for 8 weeks in conjunction with a pre-exercise, periexercise, and postexercise ingestion of whey protein (WHEY) nutritional supplement or carbohydrate (CON)-based nutritional supplement...

Increased intestinal permeability has been implicated in various pathologies, has various causes, and can develop during vigorous athletic training. Colostrum bovinum is a natural supplement with a wide range of supposed positive health effects, including reduction of intestine permeability. We assessed influence of colostrum supplementation on intestinal permeability related parameters in a group of 16 athletes during peak training for competition. This double-blind placebo-controlled study compared supplementation for 20 days with 500 mg of colostrum bovinum or placebo (whey)...

Obesity is a serious public health problem and being multifactorial is difficult to tackle. Since the intestinal ecosystem's homeostasis is, at least partially, diet-dependent, its modulation may be triggered by food components that are designed to exert a modulatory action leading to a health-promoting effect. Milk whey proteins, are considered as such promising factors since they influence satiation as well as body weight and constitute the source of biologically active peptides which may modulate health status locally and systemically...

Context: Androgen deprivation therapy (ADT) is a common prostate cancer (PCa) treatment but results in muscular atrophy. Periodic increases in muscle protein synthesis (MPS) that occur after resistance exercise or protein intake may ameliorate this muscle loss, but the impact of these anabolic stimuli during ADT is unclear. Objective: To determine the acute MPS response to whey protein supplementation with and without resistance exercise during ADT. Design: Acute response in PCa patients vs age-matched controls (CON)...

It has been proposed that protein supplementation during resistance exercise training enhances muscle hypertrophy. The degree of hypertrophy during training is controlled in part through activation of satellite cells and myonuclear accretion. PURPOSE: To determine the efficacy of protein supplementation (and the type of protein) during traditional resistance training on myofiber cross-sectional-area, satellite cell content and myonuclear addition. METHODS: Healthy young men participated in supervised whole body progressive resistance training 3d/wk for 12 weeks...

Protein supplements are consumed for an expected increase in muscle mass and improved exercise performance, but as their impact on lithogenic parameters are unknown, we aimed to evaluate the effects of Whey protein (WP) and Albumin upon the risk factors for nephrolithiasis. WP or Albumin supplements (one scoop/day) were administered for 3 days to 18 healthy volunteers, with 1-week washout period between them. Serum and 24-h urine samples were collected at baseline and after completing each intervention. All participants were asked to replicate their baseline diet during the subsequent urine collection...

Whey protein is a source of protein that was isolated from milk. Whey proteins are composed of higher levels of essential amino acids. The role of diet in acne etiology has been investigated for several years. It was established that milk and milk products can trigger acneiform lesions, and recent evidence supports the role of whey protein supplements in acne. Herein, we report 6 healthy male adolescent patients developing acne located only to the trunk after the consumption of whey protein supplements for faster bodybuilding...

The objective of the study was to investigate whether co-ingestion of carbohydrate and protein as compared with protein alone augments muscle protein synthesis (MPS) during early exercise recovery. Two months old rats performed 10 repetitions of ladder climbing with 75% of body weight attached to their tails. Placebo (PLA), whey protein (WP), or whey protein plus carbohydrate (CP) was then given to rats by gavage. An additional group of sedentary rats (SED) was used as controls. Blood samples were collected immediately and at either 1 or 2 h after exercise...

BACKGROUND: Allergy is common and may be associated with foods, including cow's milk formula (CMF). Formulas containing hydrolysed proteins have been used to treat infants with allergy. However, it is unclear whether hydrolysed formulas can be advocated for prevention of allergy in infants. OBJECTIVES: To compare effects on allergy and food allergy when infants are fed a hydrolysed formula versus CMF or human breast milk. If hydrolysed formulas are effective, to determine what type of hydrolysed formula is most effective, including extensively or partially hydrolysed formula (EHF/PHF)...

BACKGROUND: The development of effective nutritional strategies in support of muscle growth for patients with chronic obstructive pulmonary disease (COPD) remains challenging. Dietary essential amino acids (EAAs) are the main driver of postprandial net protein anabolism. In agreement, EAA supplements in healthy older adults are more effective than supplements with the composition of complete proteins. In patients with COPD it is still unknown whether complete protein supplements can be substituted with only EAAs, and whether they are as effective as in healthy older adults...

BACKGROUND: High-intensity exercise induces many metabolic responses. In is unknown whether the response in the peripheral blood mononuclear cells (PBMCs) reflects the response in skeletal muscle and whether mRNA expression after exercise can be modulated by nutritional intake. The aims were to (i) investigate the effect of dairy proteins on acute responses to exercise in skeletal muscle and PBMCs measuring gene expression and (ii) compare this response in young and older subjects. METHODS: We performed two separate studies in young (20-40 years) and older subjects (≥70 years)...

BACKGROUND: Previous research has demonstrated the permissive effect of insulin on muscle protein kinetics, and the enhanced insulin sensitizing effect of chromium. In the presence of adequate whole protein and/or essential amino acids (EAA), insulin has a stimulatory effect on muscle protein synthesis, whereas in conditions of lower blood EAA concentrations, insulin has an inhibitory effect on protein breakdown. In this study, we determined the effect of an amylopectin/chromium (ACr) complex on changes in plasma concentrations of EAA, insulin, glucose, and the fractional rate of muscle protein synthesis (FSR)...

BACKGROUND: Diabetes mellitus (DM) is associated with severe immune system complications. Camel whey protein (CWP) decreases free radicals (ROS) and modulates immune functions, but its effect on DM-impaired immune systems has not been studied. We investigated the impact of CWP on the immune system in a Type 1 diabetes mouse model. METHODS: Three experimental groups were used: (1) non-diabetic control; (2) diabetic; and (3) CWP-treated diabetic mice. RESULTS: Induction of diabetes by streptozotocin was associated with reduction of body weight and insulin level, increase in glucose level and pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), and reduction in IL-2 and IL-4 levels...
