  • However, high protein diets (defined as an intake above the current RDA) are promoted intensively by the nutritional supplements industry and they are considered to be “the gold standard” by many athletes (especially bodybuilders) for muscle development and/or body fat loss.

  • On the other hand, several scientists claim that the overuse of protein supplements or high dietary protein intake could cause disorders to human health [1–7]. The aim of this review study is to determine the potential health dangers due to high protein/high meat intake obtained from diet or nutritional supplements based on the human studies existent in the literature.

      High protein potential danger to health
  • Extra protein is not used efficiently by the body and may impose a metabolic burden on the bones, kidneys, and liver. Moreover, high-protein/high-meat diets may also be associated with increased risk for coronary heart disease due to intakes of saturated fat and cholesterol or even cancer [

  • Diet which is high in protein generates a large amount of acid in body fluids [2]. The kidneys respond to this dietary acid challenge with net acid excretion, and, concurrently, the skeleton supplies buffer by active resorption of bone resulting in excessive calcium loss [2]. Moreover, acid loading directly inhibits renal calcium reabsorption leading to hypercalciuria in combination with the exorbitant bone loss

      High protein intake may lead to excessive bone loss.
  • igh levels of dietary protein, at least a portion of the increase in urinary calcium reflected increased bone resorption [1
  • There was a consistent increase in urinary calcium with the high-protein diet averaging 88% above control in the normals and 82% in the patients
  • An increase in urinary calcium excretion was found indicating that the animal protein-induced calciuric response could be a risk factor for the development of osteoporosis
  • An increase in vegetable protein intake and a decrease in animal protein intake may decrease bone loss and the risk of hip fracture [
  • Additionally, dietary excess (2 g/kg/day) in animal protein for 1 week led to significant changes in urinary calcium excretion rates
  • releases calcium to be excreted by the kidney. This protein-induced hypercalciuria could lead to the formation of calcium kidney stones
  • animal protein is also the major dietary source of purines, the precursors of uric acid. Excessive intake of animal protein is therefore associated with hyperuricosuria, a condition present in some uric acid stone formers [5]. Uric acid solubility is largely determined by the urinary pH. As the pH falls below 5.5 to 6.0, the solubility of uric acid decreases, and uric acid precipitates, even if hyperuricosuria is not present
  • animal protein-rich diet was associated with the highest excretion of undissociated uric acid due to the reduction in urinary pH
  • arian cancers. Thus, reducing red meat intake might lower the risk for several common neoplasms [26]. Moreover, highprotein/high meat diet could cause disorders of liver function and precipitated progression of coronary artery disease. Hyperalbuminemia and elevated transaminases have been associated with high-protein diet [27]. Individuals on high protein supplements developed intermittent abdominal pain, transient elevations in transaminases, and hyperalbuminemia without there being any identifiable cause.
  • igh-protein diets may precipitate progression of CAD through increases in lipid deposition and inflammatory and coagulation pathways

      Effect of food choices/ dairy on microbiota
  • Interestingly, there was an increase of other Actinobacteria, including several species of the Coriobacteriaceae family. This effect could be attributed to the increased levels of lactose in the diet provided by regular intake of the test product.

  • Recent position stands from the Academy of Nutrition and Dietetics, Dietitians of Canada and the American Colleges of Sports Medicine [25], and the International Society of Sports Nutrition [26] recommend a protein intake of 1.2–2.0 g·kg body weight (BW)−1·day−
  • With these factors in mind, it is evident that resistance exercise is fundamentally anabolic and may actually shift the utilization of dietary amino acids towards muscle protein synthesis and thus a greater ratio of circulating amino acids are being retained by the body’s largest protein pool (skeletal muscle) in both the fasting and fed states. Hence, a person engaged in a regular resistance exercise training program is likely at the lower end of required protein intakes to optimize muscle adaptive response when compared with those engaged in other exercise activities. For example, Kato et al. [29] have demonstrated that protein requirements are slightly elevated for endurance-trained adults consuming an energy-balanced diet (~1.8 g·kg body weight (BW)−1·day−1).
  • Moreover, regular resistance exercise training results in increased whole body nitrogen retention when compared with the untrained state

  • ~1.6 g·kg body weight (BW)−1·day−1 is maximal to support resistance-exercise-induced strength and lean mass gain in healthy adults in energy balance
  • Recently, it has been shown that the ingestion of beef and skim milk (both providing 30 g of protein) were equally as effective in stimulating post-exercise muscle protein synthesis rates throughout a 0–5 h post-exercise period [39]. Similarly, egg ingestion has been shown to be effective at stimulating the post-exercise muscle protein synthetic response [41]. Additionally, there is emerging evidence that the food matrix in which the protein is consumed may have a direct influence on the post-exercise muscle protein synthetic response in healthy young adults.

  • lthough adequate protein throughout the day is necessary, extra strength training is what leads to muscle growth, not extra protein intake. You can’t build muscle without the exercise to go with it.

      Extra protein doesnt add muscles .
  • Extra protein intake can also lead to elevated blood lipids and heart disease, because many high-protein foods you eat are high in total fat and saturated fat

      High protein means high fat diet content .
  • The recommended dietary allowance to prevent deficiency for an average sedentary adult is 0.8 g per kg of body weight. For example, a person who weighs 75 kg (165 pounds) should consume 60 g of protein a day.
