Subscribe to the JOM Introduction A food additive is any substance not commonly regarded or used as food, which is added to, or used in or on, food at any stage to affect its keeping quality, texture, consistency, taste, colour, alkalinity or acidity, or to serve any other technological function in relation to food, and includes processing aids in so far as they are added to or used in or on food.

By following the Conners' Scale criteria, especially tranquil children may score as low as O, whereas the most severely hyperactive children can attain scores as high as Different commentators seem to have set their criteria of hyperactivity at different levels; however 15 seems to be the most frequent figure.

Obviously therefore the higher the cut-off point for the diagnosis is set, the more strict also would be the criteria. The final results indicated that In fact follow-up studies of young adolescents diagnosed as hyperactives when children have shown, when compared to controls, a significantly higher drop-out and expulsion rate from schools, a greater involvement in both drug and alcohol abuse, a higher rate of motor vehicle accidents,48 a greater risk of developing criminal tendencies, as well as appearing before courts.

Despite an apparent decrease in the ratings of hyperactivity over the years, as adolescents and adults they still seem to continue to use impulsive rather than reflective approaches to cognitive tasks, are still distractable, generally emotionally immature, have a poor self-image and are frequently unable to maintain goals.

He arrived at this conclusion by observing that certain children, who seem to react neurophysiologically to aspirin, reacted also in a similar manner to natural foods containing salicylates. This led him to study further the effect of other low molecular compounds, such as artificial food additives, on childrens' health and behaviour, finding similar results.

He observed further that the children, whose hyperactive behaviour was a direct manifestation of this elevated sensitivity, can be treated effectively by simply removing from their diet all foods containing artificial food additives as well as foods containing natural salicylates.

For example, both Conners90 and Harley92 employed in their challenge procedure 26mg artificial food colours daily, Weiss used 35mg,20 and a study by Swanson, which incidentally found a clear supportive evidence to Feingold's hypothesis, used a daily challenge dose of mg.

This became apparent when the Food and Drug Administration studied 5, randomly selected children between agesdetermined that the 90th percentile for daily consumption of artificial food dyes within this age group was mg. For the population as a whole the FDA found an average daily mean to be Even though 50mg could be considered as a substantial dose, such a quantity of tartrazine could easily be consumed by an individual drinking only a few bottles of soft drinks per day.

This phenomena was not found among the controls.

It was suggested therefore that tartrazine seems to act as a zinc chelating agent in susceptible individuals. Furthermore, that zinc depletion may also be one of the potential causes of childhood hyperactivity.

Subsequent work has also found that amaranth can cause female rodents to reabsorb some of their own foetuses. It is also used as a colouring agent in crisps, bread, sauces, gravy browning etc. The main recurring problem about the safety of caramels concerns the presence of an impurity called 4-Methylimidazole, produced by processes using ammonia, which leads to convulsions when fed to rats, mice and chicks.

It has been also found that ammoniated caramels can affect adversely the levels of white blood cells and lymphocites in laboratory animals.

Furthermore, a study on rabbits provided evidence that even small doses of ammoniated caramels seem to inhibit the absorption of vitamin B6. Two of the primary metabolites of this colouring have been found to act as a cardiotoxin.Dear Apple and Mia, to develop your conceptual framework, as this article suggests, you will need to read relevant literature about your topic.

TEACHER EVALUATION - a review of the literature. This page summarises and quotes from the surprisingly sparse literature on the evaluation and appraisal of teachers. Performance Evaluations: Performance Evaluation - Performance management is tool purposely used to motivate employees to examine themselves and determine if they have selected the profession that is best for them; consequently the feedback an employee receives from their superior supports them with increase their knowledge and skills.
