Amino acids are essential for many metabolic functions of the body, including muscle building and maintenance. The US Institute of Medicine UU It informs that there are nine amino acids that you should consume in your diet. Your body can synthesize the remaining 11 amino acids from carbohydrate precursors. Regular consumption of more than the daily need for amino acids, particularly those that your body can not synthesize, can have negative consequences for your health.
The World Health Organization states that for most amino acids, it is difficult for researchers to determine an exact recommended daily intake. However, the organization affirms with certainty that once your body uses the amino acids that you need, the excess of amino acids enters an oxidative cycle. During this cycle the kidneys must process excess amino acids and expel them from your body. The increased workload of the kidneys can cause damage, especially if you have already weakened kidney function.
In relation to your kidney function is your nitrogen balance after processing the amino acids. Harris R. Lieberman et al. count in "Nutritional Neuroscience" that the nitrogen balance is the result of the intake of amino acids, minus the amount of nitrogen in your body excretions. If you consume too many amino acids, especially if it is an excessive and unbalanced consumption, you will begin to excrete more amino acids than you eat, resulting in a negative nitrogen balance. This negative nitrogen balance will remain until you correct your diet.
In a research paper on amino acids in 2011, published in "The Journal of Cachexia, Sarcopenia and Muscles," Francesco S. Dioguardi reports that research on the toxicity of amino acids is deficient, but researchers firmly believe that too much methionine can have negative consequences for your health. Dioguardi cites carotid artery lesions, cellular oxidative damage and deterioration of nitric oxide production in the possible side effects of too much methionine in the diet. Arginine and glutamine are two other amino acids that can have toxic effects when consumed too much, but more research is needed.
The protein found in foods of animal and non-animal origin is the primary source of amino acids. Registered dietitian Katy James states that a sedentary adult requires only 0.8 g of protein per kilogram of body weight, or approximately 0.36 g per pound. She also says that most people easily meet this requirement through the daily diet.A negative side effect of eating more protein than you need is that your body will convert part of this protein into fat and it will be stored in the fat cells in your body for future use as energy.
