  • 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

Animal protein plant health effects

  • urther studies have shown that eating more processed red meat may actually increase the risk of dying from heart disease. Processed meats include smoked meat, sausage, hot dogs, salami, bacon, and canned meat.
  • Some plant proteins, such as quinoa, are complete proteins—which means they contain all 9 essential amino acids that we need. Others are missing some amino acids, so it is important to eat a variety of foods to get all 9.
  • re at a lower risk of certain diseases including cancers, type 2 diabetes, hypertension, obesity, and ischemic heart disease.

  • Eating soy protein in place of animal protein has been found to reduce bad cholesterol and triglycerides, which are linked to heart disease. Other studies have shown that soy contributes to blood sugar control and reduced body weight.
