Maximum intake

After an intensive research on maximum intake dose permitted for human beings through different pathways, it has been observed that the most reliable was to consider the total intake since the particular intake pathway data were not clear enough. After comparing these values, the following statements can be made ... 

The major urinary metabolite of di(2-ethylhexyl) adipate, 2-ethylhexanoic acid, has been shown to be an appropriate marker for biological monitoring of dietary di(2-ethylhexyl) adipate intake (Loftus etal., 1993, 1994). A limited population study in the United Kingdom was undertaken to estimate the daily intake of di(2-ethylhexyl) adipate following intake of a mean dose of 5.4 mg di(2-ethylhexyl) adipate presented with food. The study involved the determination of the urinary metabolite, 2-ethyl-hexanoic acid (24-h mine sample) in 112 individuals from five geographical locations. A skewed distribution with a median value for the daily intake of 2.7 mg was determined (Loftus et al., 1994). This value is about one third of the indirectly estimated maximum intake of 8. 2 mg per day. The probability of a daily intake in excess of 8.2 mg in the limited population (112 individuals) was calculated to be 3% (Loftus etal, 1994).

The certification committee allows the farm to purchase conventional feed and forage during a shortage of organic feed. Flowever, the conventional feed and forage cannot exceed 15% for non-ruminants on a dry matter basis. Daily maximum intake of conventional feed intake cannot exceed 25% of the total daily feed intake on a dry matter basis. Exemptions due to severe weather and disasters are permitted. Detailed feed records must be kept and the conventional feed must be OFDC-approved. 

In turn, the Ni intake is 361 fig day-1 (range 45-764 fig day-1). The maximum intake is around 600 fig day-1, the highest acceptable value [1] above which sensitized individuals may show allergic symptoms. The value obtained in this study exceeds the ranges allowed in the UK (140-150 fig day-1) [44, 45], the United States (69-162 fig day-1) [46], Denmark (60-260 fig day-1), [47], and France (74 fig day-1) [35]. The food category that mostly contributes to the Ni total daily intake is cereals and tubers (see Table 10.7 34 percent). 

Toxicity to humans was initially estimated to be 15 pg/person (mean value) based on the toxin content of the mussels from the blooms that originated the first two toxic episodes, 0.6 pg/g of meat (Killary Harbour) and 1.36 pg/g of meat (Arranmore) (equivalent to 0.15 and 0.4 monse nnits/g, respectively) (Ofuji et al. 1999b Satake et al. 1998a, 1998b). However, recent data showed that azaspiracid concentration is not reduced by heat (EU/SANCO 2001 Hess et al. 2005), which had been a parameter for initial calculations. Therefore, the lowest observed adverse effect level (LOEL) has been re-estimated to be within the range of 23 to 86 pg/person, with a mean valne of 51.7 pg/person (EU/SANCO 2001 FAO 2004). The non-observable adverse effect level (NOEL) was conseqnently calculated to be 80 pg/kg of shellfish meat, considering a safety factor of 3, which shonld account for individual variations, a maximum intake of 100 g per person and the lowest valne in the LOEL range. 

A Tolerable Upper Intake Level (UL). The UL is the maximum intake by an individual that is unlikely to pose risks of adverse health effects in almost all (97-98%)individu-als. It includes intake of a nutrient from all sources (food, fortified food, water, and sup-dements). Water can include fluoride and minerals depending on the source of water. "Tolerable" is used to "avoid implying any possible beneficial effect." It is the amount of vitamin that can be "tolerated" without the person s exhibiting or experiencing adverse reactions. The UL should not be considered the upper dose for those who self-dose with megadoses of vitamins. 

Methods for the determination of fonnaldehyde in drinking water are available and they utilize the same detection methods as those utilized for the analysis of formaldehyde in air, with LODs reported to be 20 ppb (Tomkins et al. 1989) and 8.1 ppb (EPA 1992b). The MRL for chronic oral exposure to formaldehyde is 0.2 mg/kg/day. If a 70-kg person is assumed, the maximum intake is 14 mg/day. If a daily intake of 2 L of water or 2 kg/day of food per day is assumed, then any analytical method must have an LOD of less than 7 mg/L for water or 7 mg/kg (ppm) for food. The cited methods for detecting formaldehyde in water have LODs far below the needed value and are sensitive enough to measure background levels in the environment no additional methods for formaldehyde detection in water are required. Other than for milk (Kaminski et al. 1993b, LOD=9 ppb), no methods for formaldehyde detection in food were found. Additional methods for detection of formaldehyde in foods are needed. Methods for the detection of formaldehyde in soil are not adequately described in the available literature. 

No evidence of nail disease was observed in a population living on selenium-rich ranches in the western United States (Longnecker et al. 1991). Doses of selenium were calculated to be between 0.001 and 0.01 mg/kg/day, corresponding to a maximum intake of 0.724 mg/day. Whole blood selenium concentrations were 0.18-0.67 mg/kg. Although these values for the United States are consistent with studies of the Chinese population, only one or a few individuals ingested the highest doses. 

The mean daily sulfur intake varied between 476 mg in women and 619 mg in men. The significantly different S intake is caused by the different high DM intakes, as men consumed on average 17% more food DM than women. The highest daily sulfur consumption of 1492 mg in men was more than two-fold the maximum intake in women (666 mg) (Holland 1996). However, amounts of sulfur taken in by a population of a former sulfur-polluted area were less than the weekly intake of 7.0-... 

The recommended daily intake of iodine is 150pg for adults, whereas the lowest and maximum intakes per day are 70 pg and 1 mg, respectively, in the Nordic countries. The recommended daily intake of iodine is 90 pg for children 2-5 years, 120 pg for children 6-9 years, and 150 pg for children 10 years and older and adults in Norway (NNR, 2004). Pregnant women are recommended a daily intake of 175 pg, and lactating women 200 pg of iodine. These recommendations are in line with the World Health Organization (WHO, 2001). 

In addition, five prospective within-population cohort studies have been carried out, four of them on coronary heart disease and one on strokes. The four coronary heart disease studies were carried out in The Netherlands (Zutphen) [139], the USA (Health Professionals study) [140], the U.K. (the Caerphilly study) [141], and Finland [142]. In the Zutphen study, coronary heart disease was inversely associated with flavonol intake, in which a maximum intake of 42 mg/day and a minimum of 12mg/day were recorded. A clear dose-response correlation was observed. In the Health Professionals study, a modest non-significant inverse association was found (flavonoid intake between 40 mg/day and 7 mg/day). The Finnish study indicated a weak inversely associated correlation, while the Caerphilly study involving Welsh men showed that flavonoid intake increased the mortality.

Some centers allow small amounts of galactose and/or fructose in order to improve nutrient intake and variety in the diet of patients with GSD-1, as long as so doing does not compromise metabolic control. For each meal, a maximum intake of 2.5 g of either galactose or fructose (equivalent to 5 g of lactose or sucrose) is allowed [9]. 

A study of the daily intake of di-(2-ethylhexyl) adipate conducted in 1987 in UK estimated maximum intake at 16 mg/ day. Similar studies conducted five years later gave maximum intake of di-(2-ethyl-hejgrl) adipate at 8.2 mg/day. This was achieved by product reformulation with special attention given to chng film. The intake of acetyl tributyl citrate was found to increase because of usage of vinylidene chloride copolymer films in nticrowave...
