[The problem of food allergies at the present stage].

The increase in the number of patients with allergic diseases, which are caused by food allergy, has become one of the leading problems of the XXI century. Expanding the spectrum of food allergens responsible for the development of food allergies raises the question of increasing knowledge in this area for practitioners. The article presents data on causally significant food allergens and food additives that cause the development of food allergies, as well as information on the main food proteins and their components involved in the formation of cross-reactivity. Modern methods of molecular diagnostics and an algorithm for diagnosing food allergies and food intolerances are presented.

Sweeteners as food additives in the XXI century: A review of what is known, and what is to come.

Sweet has always been a very important basic taste for mankind, although sweetness is always related to either weight gain or teeth decay. Sweeteners entered the food industry back in the 1800's and are now staple in foodstuffs. Despite their long relationship with food, sweeteners have been in the spotlights for many reasons. Since being the perfect choice for diabetics, to the dangers concerning toxicity, cancer and other health issues associated with their consumption, sweeteners have come a long way. The conflicting results for the same sweeteners and the divergent regulations are fuel for a wide debate on the impact of sweeteners in the industry, health and lifestyle of mankind. In this review, the history, main concerns, benefits, disadvantages, classification and future trends are revisited for nutritive, intense and natural food additives, while future perspectives are hypothesized.

GRAS from the ground up: Review of the Interim Pilot Program for GRAS notification.

After publication of the draft Generally Regarded As Safe (GRAS) rule in 1997, the United States (US) Food and Drug Administration (FDA) initiated an Interim Pilot Program encouraging the notification to FDA of GRAS determinations. This paper analyzes GRAS notifications submitted during the Interim Pilot Program along with warning letters issued during the same time period to better understand the evolution of the program and anticipate the future GRAS landscape. The success of the GRAS Notification program is demonstrated by the increasing rate of GRAS Notifications submitted to the FDA during the Interim Pilot Program, as well as the shift from a primarily domestic process to a process featuring an equal to greater contribution of GRAS Notifications from companies outside the US. Analysis of the first 600 GRAS Notifications revealed a number of interesting trends regarding the inclusion and composition of GRAS Expert Panels; differences in notifications for substances with nutritive, processing aid, or effect; and the duration of GRAS Notifications. The review of FDA warning letters associated with GRAS issues provides additional insight into GRAS notices, from the perspective of ongoing post-market emphasis on food safety with the implementation of the GRAS Final Rule.

"Our sickness record is a national disgrace": Adelle Davis, nutritional determinism, and the anxious 1970s.

America's most widely read nutritionist of the postwar decades, Adelle Davis, helped to shape Americans' eating habits, their child-feeding practices, their views about the quality of their food supply, and their beliefs about the impact of nutrition on their emotional and physical health. This paper closely examines Davis's writings and argues that even though she is often associated with countercultural food reformers like Alice Waters and Frances Moore Lappé, she had as much in common with the writings of interwar nutritionists and home economists. While she was alarmed about the impact of pesticides and food additives on the quality of the food supply, and concerned about the declining fertility of American soil, she commanded American women to feed their families better and promised that improved nutrition would produce stronger, healthier, more beautiful children who would ensure America's future strength. She believed that nearly every health problem could be solved through nutrition, and urged her readers to manage their diets carefully and to take extensive supplementation to ensure optimum health. As such, she played an important role in creating the ideology of "nutritionism" - the idea that food should be valued more for its constituent parts than for its pleasures or cultural significance.

New thoughts concerning the epidemic of rickets: was the role of alum overlooked?

Recent emphasis on the re-emergence of nutritional rickets has renewed interest in the etiology and therapy of this devastating disorder. At its peak in the 19th and 20th century, rickets was a major area of study for countless experts in childhood disorders and numerous theories abounded as to its cause. These included, among others, infections, confinement or intestinal disturbances, and were largely discarded after the discovery of the role of vitamin D and the importance of ultraviolet irradiation. Once a good explanation had been found for the cause of the disorder and the curative power of vitamin D proven, whether it was obtained from the diet or through exposure to sunlight, there was no apparent need to look any further into the etiology of rickets. But in fact there may have been other contributory factors, recognition of which might have lessened the severity of the disease or hastened recovery. One of these theories might be of particular interest to pediatric nephrologists because it relates to insoluble aluminum-based phosphate binders. Namely, alum used as an adulterant in bread in certain locations may have contributed to metabolic bone disease during the great epidemic of rickets.

[Hexa-sabbath. Foreign matter and vital substances, experts and the critical consumer in the FRG during the 1950s and 1960s]. / Hexa-Sabbat. Fremdstoffe und Vitalstoffe, Experten und der kritische Verbraucher in der BRD der 1950er und 1960er Jahre.

In the late Fifties and early Sixties the regulation of food additives represented a remarkable turning point in German consumer politics, establishing a debate about decision making and policy advice, altering the discourse of purity and contamination, and inaugurating a new political actor, the organized critical consumer. The amendment of the Food Law in December 1958 functioned as a negotiation process between representatives of science, industry and the state, which was institutionalized in the Senate Commissions of the German Research Foundation. While these Commissions for preservatives, foreign matter and colorants worked behind closed doors, a public discourse about the "toxic condition" of modern life and the negative role of the pharmaceutical and chemical industry gained strength. The debate about the admission of hexamethylenetetramine (hexa) took part at a crucial moment. Hexa was used as a preservative in the fish industry. But its anti microbial effectiveness was caused by the decomposition of hexa to formaldehyde. Despite the commission's verdict against hexa, the lobbying activities of the industry granted it a reprieve. In the media, the case of hexa was seen as a touchstone for the capacity of negotiated decision making and the ability of rational scientists to resist the demands of industry. Finally, in 1963 it was the new political actor of the organized critical consumer, heir and successor to the housewife federations as well as to "purists" advocating life reform, who, supported by the media, enforced the prohibition of hexa as a preservative.

Food chemistry and U.S. food regulations.

The Agriculture and Food Chemistry Division (AGFD) was founded in 1908 shortly after passage of the first U.S. food regulations in 1906. Modern food regulations started with the passage of the Food Drug and Cosmetic Act in 1938. This Act has been amended several times to keep pace with developments in food chemistry. In 1958 the Food Additives Amendment was enacted to control substances added to food. Since 1958 scientific techniques have been developed to evaluate the safety and carcinogenicity of substances in the food supply. In the 1970s and 1980s AGFD symposia and books addressed compounds of concern in foods. In the 1990s food safety and nutrition regulations followed new developments in food and nutrition chemistry. Recently, the well-studied toxin acrylamide was discovered in food and presented regulators with new questions on safety and control in the food supply. Discoveries and developments in chemistry such as those in nanotechnology will continue to present challenges to food regulators.

One hundred years of commercial food carbohydrates in the United States.

Initiation and development of the industries producing specialty starches, modified food starches, high-fructose sweeteners, and food gums (hydrocolloids) over the past century provided major ingredients for the rapid and extensive growth of the processed food and beverage industries. Introduction of waxy maize starch and high-amylose corn starch occurred in the 1940s and 1950s, respectively. Development and growth of the modified food starch industry to provide ingredients with the functionalities required for the fast-growing processed food industry were rapid during the 1940s and 1950s. The various reagents used today for making cross-linked and stabilized starch products were introduced between 1942 and 1961. The initial report of enzyme-catalyzed isomerization of glucose to fructose was made in 1957. Explosive growth of high-fructose syrup manufacture and use occurred between 1966 and 1984. Maltodextrins were introduced between 1967 and 1973. Production of methylcelluloses and carboxymethylcelluloses began in the 1940s. The carrageenan industry began in the 1930s and grew rapidly in the 1940s and 1950s; the same is true of the development and production of alginate products. The guar gum industry developed in the 1940s and 1950s. The xanthan industry came into being during the 1950s and 1960s. Microcrystalline cellulose was introduced in the 1960s. Therefore, most carbohydrate food ingredients were introduced in about a 25 year period between 1940 and 1965. Exceptions are the introduction of maltodextrins and major developments in the high-fructose syrup industry, which occurred in the 1970s.

Controversial medical and agri-food biotechnology: a cultivation analysis.

Whether biotechnology is one or several developments is not clear. Once distinctions are required, the question is: Which one prevails? When the good, the bad, and the ugly settle, where do they fall? Evaluation implies distinction, and representation drives attitude. The controversies over biotechnology are fertile ground on which to study these issues. The imports of genetically modified (GM) soya into Europe in 1996-97 and the cloning of Dolly the sheep from adult cells in 1997 changed the symbolic environment for genetic engineering. The ensuing public controversies came to focus mainly on field trials of GM crops and food labeling. This paper will explore the relationship between quality press coverage and public perception, in particular the cultivation of the contrast between "desirable" biomedical (RED) and "undesirable" agri-food (GREEN) biotechnology in Britain. The argument draws on a systematic analysis of the British press coverage of biotechnology from 1973 to 1999 and analysis of public perceptions in 1996 and 1999. The paper concludes that the debate over GM crops and food ingredients fostered the RED-GREEN contrast among the newspaper-reading public, thereby shielding RED biotechnology from public controversy, and ushered in a realignment of the regulatory framework in 2000.

Umami and food palatability.

Umami is the term that identifies the taste of substances such as L-glutamate salts, which were discovered by Ikeda in 1908. Umami is an important taste element in natural foods; it is the main taste in the Japanese stock "dashi," and in bouillon and other stocks in the West. The umami taste has characteristic qualities that differentiate it from other tastes, including a taste-enhancing synergism between two umami compounds, L-glutamate and 5'-ribonucleotides, and a prolonged aftertaste. The key qualitative and quantitative features of umami are reviewed in this paper. The continued study of the umami taste will help to further our general understanding of the taste process and improve our knowledge of how the taste properties of foods contribute to appropriate food selection and good nutrition.

Panis populi--bread and public health in Australia.

The 'standard loaf, 680 gm, white, supermarket-purchased' as expressed in the Consumer Price Index, is but the basic form of bread sold to the Australian public. In the public health context, three themes have been intimately associated with bread--quality control, price control and bread used as a vehicle for supplementary nutritive agents important in preventive medicine. Price control, through assizing, has been a feature of bread marketing in western communities for seven centuries; and bread remains the last item on which price control (although seldom enforced) exists in Australia. Quality control, for public health, is determined both by regulation and by the force of increasingly literate consumers, of whom women occupy the most important determinant. From the preventive medicine point of view, important themes in bread quality, such as its use to reduce laxative sales on the one hand and to reduce the demographic incidence of colonic cancer on the other, remains outside formal regulation. Australia is a relatively conservative nation in the context of nutritional additives. It was not until 1953 that the National Health and Medical Research Council approved the addition of extra B vitamins to bread. Currently, folic acid is added as a discretion to selected high-premium breakfast cereals in Australia in one attempt to reduce the incidence to neural tube defects. The addition of such ingredients to bread remains an unrealised, but potentially important aspect of preventive medicine in Australia.
