Food sources of glutathione Food sources of glutathione: glutathione (GSH) is an antioxidant and detoxifying agent whose role was protective in numerous clinical studies. GSH is synthesized rapidly in the liver, kidneys and other body tissues, including the gastrointestinal tract. This process is supported by the aging and disease, as these two conditions which must be reduced in the tissues and blood of glutathione. Dietary forms of glutathione are efficiently absorbed into the bloodstream, but the same does not apply humans.When glutathione supplements in healthy volunteers, a single dose of up to 3,000 mg Glutathione researchers found there was no increase in blood levels of glutathione . (Witschi A, Reddy S, Stofer B, Lauterburg BH. The systemic availability of oral glutathione. Eur J Clin Pharmacol 1992, 43 (6) :667-9.) Authors of this study concluded: "It is not possible to control the spread of glutathione clinically useful for oral administration of a single dose of 3 g of glutathione. "Johnson and staff (Johnston CJ, Meyer, CG, JC Srilakshmi. Vitamin C increased red blood cell glutathione in healthy adults. Am J Clin Nutr 58:103-5, 1993) noted that the levels of glutathione in the blood of about 50% in healthy people to 500 mg of vitamin C daily. Vitamin C facilitates an increase in blood levels of glutathione by the body with a nutrient that is essential for the production of it.In addition to vitamin C, dietary sources of glutathione and many other nutritional compounds can help to increase levels glutathione, including N-acetyl cysteine (NAC), alpha-lipoic acid, glutamine, methionine, and proteins such as whey (Bounous, G., and Gold, P., The biological activity of these serum proteins milk food [Immunocal]: The role of glutathione, Clin. Invest. med. (1991) 14 (4) :296-309.). N-acetyl cysteine was used in combination with glutamic acid (or glutamine) and glycine (Clark, J., and beyond, NAC was used in combination with diet of protein (Quigo D., Cysteine metabolism and metal toxicity, Alternative Medicine Review (1998) 3 (4) :262-270.). HERBS: The herb milk thistle, an excellent source of antioxidants with silymarin may help prevent the depletion of glutathione in the liver. Silymarin is many times more antioxidant, better known antioxidants like vitamins E and vitamin C. The protective effect of silymarin against liver damage has been demonstrated in a series of scientific studies. Silymarin has been shown to protect against liver damage caused by highly toxic chemicals (This toxicity is determined by their ability to be unstable, dangerous and destructive compounds called free radicals), with Amanita toxin, carbon tetrachloride, Galaktosamin, and praseodymium nitrate. Silymarin enhances detoxification in the liver by preventing the exploitation of the liver glutathione.Glutathione is essential for the liver to detoxify. The higher the liver glutathione content, the greater the ability of the liver to detoxify harmful chemicals. chemicals that can damage the liver, (including alcohol and acetominophen), because the concentration of glutathione in the liver is greatly reduced, so that the hepatocytes (liver cells) susceptible to damage. Silymarin not only prevents the depletion of glutathione from alcohol and other toxins (Chrungoo VJ et al. Indian J Exp Biol 1997 Jun; 35 ( 6) :611-7.), but the level of glutathione in liver cells (hepatocytes) (Valenzuela A et al. Planta Med 1989 Oct; 55 (5) :420-2nd) and possibly up to 35% . Curcumin may also help, as mediators of tissue glutathione levels (Dickinson DA, Iles, KE, Zhang, H., Blank, V., and Forman, HJ, Curcumin altered EpRE and AP-1-binding complex and raises glutamate – cysteine – ligase gene expression, FASEB J. (2003) 17 (3) :473-475.) alpha lipoic acid also has the ability to increase glutathione and a strong antioxidant in numerous scientific studies.VITAMINS and Minerals: Vitamin B6, The riboflavin and selenium is in the production of glutathione, nutrition and adequate intake of foods that are rich (or complement) of these vitamins and minerals can help the body to optimize glutathione production.MILK & BASED PRODUCTS MEAT: Dietary glutathione occurs in highest amounts in fresh (uncooked) of meat in moderate amounts in some fruits and raw vegetables, and is not, or only in small amounts in grains and pasteurized dairy products (DP Jones , COATES RJ, Flagg EW, et al. (1992) Glutathione in foods in National Cancer Institute of health and dietary history questionnaire. Nutr Cancer 17: 57-75). foods rich in sulfur amino acids are usually the best source glutathione. Although these proteins whey is one of the best precursors (building blocks) of glutathione, it contains only moderate levels of glutathione naturally. Freshly prepared (rare or raw) meat, raw (unpasturized) milk and raw eggs are especially rich source of glutathione. Cooking reduces glutathione content, storage, and food Glutathione. In milk put aside for later use by breast-feeding infants, a 73-79% loss of glutathione is done when the milk was either chilled or at room temperature for two hours. (Ankrah NA, Appiah-Opong R, C. Dzokoto storage of human milk and glutathione content. J Trop Pediatr. 2000; 46 (2) :111-3 .) Fruits and Vegetables: fresh fruits and vegetables provide excellent levels of glutathione, but cooked food that is much less or even none, and highly processed foods contain less than minimally processed cooked foods. glutathion test fruit and vegetables can lead to conflicting results because glutathione levels vary both diurnally (Koike S, PATTERSON BD (1988) change the course of daily glutathione tomato seedlings. Hort Sci 23: 713 -714; Schupp R, Rennenberg H (1988) per day during changes glutathione content of spruce needles (Picea abies L.) Plant Sci 57: 113-117) with the stage of development of plants (BA Earnshaw, MA Johnson (1987) Control of wild carrot somatic embryo development by antioxidants. Plant Physiol 85: 273-276;), and various environmental factors (De Kok, LJ, DE KAN PJL, Tnczos OG, KUIPER JI (1981)-sulfate-induced accumulation of glutathione and frost-tolerance of spinach leaf tissue. Plant Physiol 53: 435-438; WISE RR, Naylor AW (1987) chilling enhanced photo-oxidation. Peroxydes The destruction of lipids during chilling injury to photosynthesis and ultrastructure. Plant Physiol 83: 272 – 277). Asparagi glutathione contains more than any other fruit and vegetable tested to date. (Jones, DP and others: Glutathione in food at the National Cancer Institute of health and dietary history frequency questionnaire, nutrition and cancer 17 (1 ), p. 57, 1992.) In a study that compared the antioxidant activity of potatoes, peppers, carrots, onions and broccoli, potatoes, according to the highest broccoli.Per serve asparagus, avocado, asparagus, pumpkin, okra , cauliflower, broccoli, potatoes, spinach, walnuts, garlic, tomato and raw the highest glutathione content compared to other vegetables and are particularly rich dietary sources of glutathione (see Table 1. below).
