Stands intake levels

In order to prevent indiscriminate use, regulations have been developed by many countries limiting the types, uses, and amounts of food colors permitted in foods (142,151). Since different countries allow the use of specific food colors, it is possible that foodstuffs may be imported into a country that forbids the coloring agent present in the product. Therefore, methods capable of identifying and quantifying several colors simultaneously are desired in order to verify compliance to regulations. Information on the levels of these compounds in foods is also important to assess where the dietary intake levels stand compared to the ADIs (131,152,153). 

Fluorine is available to humans, plants and animals mainly in the form of fluoride ion (F ). Body fluoride status depends on numerous factors, including the total amount of fluoride ingested daily, its bioavailability and metabolism. The adequate intake (Al) of fluoride from all sources is set by the Standing Committee on the Scientific Evaluation of the Dietary Reference Intakes at 0.05 mg/day/kg body weight this intake is recommended for all ages above 6 months, because it confers a high level of protection against dental caries and is not associated with any known unwanted health effects [8]. 

For food applications, stands are synthetically derived from plant sterols. Although the naturally occurring amounts of phytosterols in 30 g of com oil are sufficient to inhibit cholesterol absorption, """ it is not clear whether natural intakes of phytosterols significantly lower plasma LDL-C concentrations. The relatively greater intake of phytosterols by vegetarians may contribute to the lower LDL-C levels commonly observed in this population. It would, however, be nearly impossible for most individuals to obtain more than 1 g of phytosterols from food without iugesting large quantities of food. Com oil is a rich source of phytosterols, yet one would have to consume about 100 g (900 kcal) of com oil per day in order to obtain 1 g/d of phytosterols.

Patient 20 has been shown to be mosaic for a PEX6 defect (Moser, 1999). Cultured skin fibroblasts and liver biopsy samples have demonstrated a mixture of normal and abnormal cells (Pineda, et al., 1999). The patient is now 16 yr old. Developmental milestones were delayed at 2 yr. Liver biopsy showed micronodular cirrhosis. Neurologic exam at 3.5 yr showed nystagmus, head tremor, and generalized spasticity, and he was unable to walk. At 4 yr of age, he was started on a diet containing medium-chain triglycerides, pure olive oil (20% of daily fat intake), and vitamin A supplementation. This coincided with clinical improvement as evidence by the disappearance of abnormal eye movements and head tremor and reduction of spasticity. This improvement was attributed to a reduction in phytanic acid levels. Visual evoked responses improved between 4 and 6 yr of age. DHA therapy was added to the regimen at age 6.7 yr. Further improvement of the visual evoked responses occurred. At 12 yr, motor and mental improvements have been maintained. He is able to stand with support. His IQ is 60 and he attends a special school.

In the lake behind the dam is a 20 million free-standing, 256ft tall tower with water intake ports at four widely-spaced elevations. It had been predicted that water temperature downstream from the dam could be controlled by drawing water from different levels, and that, by controlling water temperature, growth of the fish would be enhanced. 

If the ADI indicated in this text refers to the ADIs currently established by JECFA for food additives and by JMPR for pesticide residues in food, an explanation is needed of what an ADI really stands for. As to whether an ADI established for food also accounts for drinking water, in most cases it seems to be more a matter of intake rather than of safety assessment. In all instances, however, a clear distinction should be maintained between figures representing "safe" levels of intake and "safe" limits in food or water.
