Tin. The widespread use of caimed foods results in a daily intake of tin that is ca 1—17 mg for an adult male (154). At this level it has not been shown to be toxic. Some grains also contain tin. Too much tin can adversely affect 2inc balance and iron metaboHsm. EssentiaUty has not been confirmed for humans. It has been shown for the rat. An enhanced growth rate results from tin supplementation of low tin diets (85). Animals on deficient diets exhibit poor growth and decreased feed efficiency (155). [Pg.388]

Aspartame (L-aspartyl-L-phenylalanine methyl ester [22839-47-0]) is about 200 times sweeter than sucrose. The Acceptable Daily Intake (ADI) has been estabUshed by JECFA as 40 mg/kg/day. Stmcture-taste relationship of peptides has been reviewed (223). Demand for L-phenylalanine and L-aspartic acid as the raw materials for the synthesis of aspartame has been increasing, d-Alanine is one component of a sweetener "Ahtame" (224). [Pg.296]

JECEA reviewed the safety studies of glutamate and endorsed its safety by allocating an Acceptable Daily Intake (ADI) for L-glutamic acid and its monosodium, potassium, ammonium, calcium, and magnesium salts as being "not specified." The scientific committee for food of EC concurred (40). [Pg.305]

Sodium Intake. Where salt is readily available, most of the world s population chooses to consume about 6,000—11,000 mg of salt or sodium chloride a day so that average daily sodium intake from all sources is 3,450 mg (8,770 mg NaCl) (13). The U.S. EDA s GRAS review puts the amount of naturally occurring sodium in the American diet at 1000—1500 mg/d, equivalent to the amount of sodium in approximately 2500—3800 mg NaCl. Thus the average daily intake of NaCl from food-grade salt used in food processing (qv) and from salt added in cooking or at the table is from 4960—6230 mg NaCl. The requirement for salt in the diet has not been precisely estabUshed, but the safe and adequate intake for adults is reported as 1875—5625 mg (14). The National Academy of Sciences recommends that Americans consume a minimum of 500 mg/d of sodium (1250 mg/d salt) (6,15). [Pg.185]

Iodized Salt. Iodized table salt has been used to provide supplemental iodine to the U.S. population since 1924, when producers, in cooperation with the Michigan State Medical Society (24), began a voluntary program of salt iodization in Michigan that ultimately led to the elimination of iodine deficiency in the United States. More than 50% of the table salt sold in the United States is iodized. Potassium iodide in table salt at levels of 0.006% to 0.01% KI is one of two sources of iodine for food-grade salt approved by the U.S. Food and Dmg Administration. The other, cuprous iodide, is not used by U.S. salt producers. Iodine may be added to a food so that the daily intake does not exceed 225 p.g for adults and children over four years of age. Potassium iodide is unstable under conditions of extreme moisture and temperature, particularly in an acid environment. Sodium carbonate or sodium bicarbonate is added to increase alkalinity, and sodium thiosulfate or dextrose is added to stabilize potassium iodide. Without a stabilizer, potassium iodide is oxidized to iodine and lost by volatilization from the product. Potassium iodate, far more stable than potassium iodide, is widely used in other parts of the world, but is not approved for use in the United States. [Pg.186]

The Sugars Task Force s Select Committee on Nutrition and Human Needs recommended a daily consumption of sugars at 10% of total calories, which approximates current (11%) daily intake levels in the United States. At this level, sucrose does contribute to the development of dental caries however, no firm evidence exists that it causes dietary imbalances or deficiencies of vitamins (qv), minerals, or trace nutrients (62). [Pg.6]

Toxicology. Inorganic tin and its compounds are generally of a low order of toxicity, largely because of the poor absorption and rapid excretion from the tissues of the metal (42—49). The acidity and alkalinity of their solutions make assessment of their parenteral toxicity difficult. The oral LD q values for selected inorganic tin compounds are Hsted in Table 2. It is estimated that the average U.S. daily intake of tin, which is mostly from processed foods, is 4 mg (see Food processing). [Pg.66]

Vanillin is Hsted in the Code of Federal Regulations by the FDA as a Generally Recogni2ed As Safe (GRAS) substance. The Council of Europe and the FAO/WHO Joint Expert Committee on Eood Additives have both given vanillin an unconditional Acceptable Daily Intake (ADI) of 10 mg/kg. [Pg.401]

Mobilization and Metabolism. The total ascorbic acid body pool in healthy adults has been estimated to be approximately 1.5 g, which increases to 2.3—2.8 g with intakes of 200 mg/d (151—158). Depletion of the body pool to 600 mg initiates physiological changes, and signs of clinical scurvy are reported when the body pool falls below 300 mg (149). Approximately 3—4% of the body pool turns over daily, representing 40—60 mg/d of metabolized, or consumed, vitamin C. Smokers have a higher metaboHc turnover rate of vitamin C (approximately 100 mg/d) and a lower body pool than nonsmokers, unless compensated through increased daily intakes of vitamin C (159). The metaboHsm of ascorbic acid varies among different species. [Pg.22]

The half-life of ascorbic acid is inversely related to the daily intake and is 13—40 d in humans and 3 d in guinea pigs, which is consistent with the longer time for humans to develop scurvy. [Pg.22]

Requirement. A daily intake of 1 pg should cover the daily loss of vitamin and maintain an adequate body pool. The RDA (34), however, has been estabHshed at 2 pg/day to cover metaboHc variation among individuals and to ensure normal semm concentrations and adequate pool sizes (Table 2). [Pg.112]

Calcium is readily abundant in the mammalian diet. A 70 kg human contains approximately 1200 g of calcium and has a daily intake of 1100 mg/day. There are no pubHshed exposure limits (38). Low levels of calcium in the blood, hypocalcemia, can lead to tetany high levels, hypercalcemia, can lead to coma and death. Calcium toxicity, above 160 mg/L in the blood, is not related to an excessive intake of calcium. [Pg.416]

Toxicologists tend to focus their attention primarily on c.xtrapolations from cancer bioassays. However, tlicrc is also a need to evaluate the risks of lower doses to see how they affect the various organs and systems in the body. Many scientific papers focused on tlic use of a safety factor or uncertainty factor approach, since all adverse effects other than cancer and mutation-based dcvclopmcnUil effects are believed to have a tlu cshold i.e., a dose below which no adverse effect should occur. Several researchers have discussed various approaches to setting acceptable daily intakes or exposure limits for developmental and reproductive toxicants. It is Uiought Uiat an acceptable limit of exposure could be determined using cancer models, but today tliey arc considered inappropriate because of tlircsholds. ... [Pg.292]

Acceptable Daily Intake (ADI) An estimate similar in concept to the RfD, but derived using a less strictly defined methodology. RfDs have replaced ADIs as the USEPA s (Agency) preferred values for use in evaluating potential noiicarcinogenic health effects resulting from exposure to a chemical. [Pg.316]

For each clironic exposure padiway (i.e., seven years to lifetime exposure), calculate a sepmate clironic hazard index from die rados of the clironic daily intake (GDI) to die clironic reference dose (RfD) for individual chemicals as described below ... [Pg.399]

For carcinogens, risks are estimated as the incremental probability of an indii idual developing ameer o er a lifetime as a result of exposure to the potential carcinogen. The slope factor (SF) converts estimated daily intakes averaged over a lifetime of exposure directly to incremental risk of an individual developing cancer. [Pg.419]

There have been numerous reports of possible allergic reactions to mercury and mercury salts and to the mercury, silver and copper in dental amalgam as well as to amalgam corrosion products Studies of the release of mercury by amalgams into distilled water, saline and artificial saliva tend to be conflicting and contradictory but, overall, the data indicate that mercury release drops with time due to film formation and is less than the acceptable daily intake for mercury in food . Further, while metallic mercury can sensitise, sensitisation of patients to mercury by dental amalgam appears to be a rare occurrence. Nevertheless, there is a growing trend to develop polymer-based posterior restorative materials in order to eliminate the use of mercury in dentistry. [Pg.461]
