Iron fortification: an update.

Iron fortification is the optimal approach to reducing the high prevalence of iron deficiency in developing countries. Selection of the iron source entails a compromise between the use of inert compounds which are poorly absorbed and chemically reactive forms with high bioavailability. Although the vehicle and fortification compound must be chosen in tandem because most iron compounds cause discoloration or rancidity, the emphasis in this review is on the food vehicle. Technology for fortifying wheat flour and bread is well established and the use of these vehicles has probably had a significant impact on iron status in Western countries. Recent studies in India indicate that the fortification of common salt is technically feasible and field trials have shown a good hematological response. Similar success has been achieved by fortifying refined sugar with NaFeEDTA in Guatemala. Rice has advantages as a vehicle in those areas where it is the staple food but the technology requires further development. Fish-based condiments have been successfully fortified with NaFeEDTA and show promise as a vehicle in East Asian countries. The fortification of infant foods poses no technical problems and should be encouraged. Additional work is needed to identify other fortification options and to develop targeted fortification programs that will direct iron to those segments of a population in greatest need.

Diet and stomach cancer incidence. A case-control study in Turkey.

A case-control study of diet and stomach cancer was conducted in Ankara, Turkey, between December 1987 and March 1988. One hundred patients with adenocarcinoma of the stomach were matched with 100 control subjects according to age, sex, and residential area. A dietary questionnaire was administered to all subjects by one of the authors. Gastric cancer patients consumed less fresh fruit and yellow-green vegetables (P less than 0.0001) and meats (P less than 0.001), and more salted food (P less than 0.001), condiments (P less than 0.0001), and salt (P less than 0.001) compared with the control group. Twenty-four percent of the gastric cancer patients and 4% of the groups with regard to the consumption of starches, fried foods, cereals, milk, dairy products, tea, alcohol, and tobacco. Stomach cancer patients brushed their teeth less frequently (P less than 0.0001) and had more deficient teeth (P less than 0.0001) compared with the control group.

A case-control study of diet and gastric cancer in northern Italy.

Dietary factors in the aetiology of stomach cancer were investigated using data from a case-control study conducted in Northern Italy on 206 histologically confirmed carcinomas and 474 control subjects in hospital for acute, non-digestive conditions, unrelated to any of the potential risk factors for gastric cancer. Dietary histories concerned the frequency of consumption per week of 29 selected food items (including the major sources of starches, proteins, fats, fibres, vitamins A and C, nitrates and nitrites in the Italian diet) and subjective scores for condiments and salt intake. Pasta and rice (the major sources of starch), polenta (a porridge made of maize) and ham were positively related with gastric cancer risk, whereas green vegetables and fresh fruit as a whole (and specifically citrus fruit) and selected fibre-rich aliments (such as whole-grain bread or pasta) showed protective effects on gastric cancer risk. Allowance for major identified potential distorting factors (chiefly indicators of socio-economic status) reduced the positive association with pasta or rice consumption, but did not appreciably modify any of the other risk estimates. When a single logistic model was fitted including all food items significant in univariate analysis, the 3 items remaining statistically significant were green vegetables (relative risk, RR = 0.27 for upper vs. lower tertile), polenta (RR = 2.32) and ham (RR = 1.60). Indices of beta-carotene and ascorbate intake were negatively and strongly related with gastric cancer risk, but the association with these micronutrients was no longer evident after simultaneous allowance for various food items. An approximately 7-fold difference in risk was found between extreme quintiles of a scale measuring major positive and negative associations.

Chromium content of foods and diets.

Comparatively few valid data are available on the chromium content of foods and on the dietary chromium (Cr) intake of various populations. This is chiefly because of the difficulties encountered in contamination control during sampling, sample pretreatment, and analysis. Moreover, there are several analytical problems involved that are mostly owing to the low concentration level of Cr in foods. However, with the recent establishment of food reference materials with certified low concentrations of Cr, the analytical validity of studies on Cr content of foods and on its dietary intake by various populations can be ascertained. With the exception of herbs and condiments, and certain other special food items with a relatively low average consumption rate, such as tea, coffee, and some candies, most foods contain Cr below 100 micrograms/kg. Staple foods, particularly cereals and milk, are very low (less than or equal to 10 micrograms/kg) in Cr, showing little or no geographic variation. Food processing may increase food Cr content depending on the process. Processes, such as meat grinding and homogenization using stainless-steel equipment, very strongly increase the Cr content of foods. Also, acidic fruit juices in contact with steel cans are high in Cr, whereas cooking in aluminium vessels reduces the Cr content of foods. Average dietary Cr intake seems to fluctuate considerably among countries. In many developing countries, such as Brazil, the Sudan, and Iran, the dietary intake is high, from 50-100 micrograms/d, whereas in certain developed countries, such as Finland, Sweden, Switzerland, and the US, the intake is 50 micrograms/d or lower and, consequently, at or below the estimated safe and adequate daily dietary intake range of 50-200 micrograms/d established by the US National Academy of Sciences. The average Cr content of human milk is below 0.5 micrograms/L, thus resulting in a very low average intake of 0.3 microgram Cr/d by exclusively breast-fed infants in the US and Finland.

Comprehensive transcriptomic analysis of BjGL1-knockout Brassica juncea: novel insights into leaf trichome formation.

Brassica juncea is a common cruciferous crop, which can be used not only for oil extraction but also as condiments and medicinal materials. It is regarded by both traditional medicine and modern nutrition science as a food with combined dietary and health promoting value. Leaf trichomes are hair-like structures differentiated from epidermal cells and constitute an important barrier against biotic and abiotic stresses, playing a crucial role in enhancing plant resistance and thus possessing significant scientific relevance. In this study, the phenotype and gene editing site of BjA06.GL1 and BjB02.GL1 knockout mustard T1 generation plants were identified. Then, RNA sequencing was performed to compare the leaf transcriptome profiles between gene-edited lines and wild-type plants, with the aim of elucidating the molecular regulatory mechanisms by which BjGL1 controls leaf trichome development and associated biological processes in mustard. The sequencing data showed that, on average, 90.64% of the reads uniquely aligned to the Brassica juncea (Xuecai) reference genome. A total of 4,604 differentially expressed genes were identified in this study. Compared with the gene knockout mutant, 1,831 genes were significantly upregulated and 2,773 genes were downregulated in mustard leaves with trichomes. The differentially expressed genes were mainly enriched in pathways related to cytochrome P450 (CYP), transporters, environmental adaptation, and plant-pathogen interactions. These pathways are closely associated with secondary metabolite biosynthesis, transmembrane transport, and responses to abiotic stress and pathogen defense. qRT-PCR validation confirmed consistent expression trends of trichome regulatory genes screened from transcriptome data. This study provides an important theoretical basis for elucidating molecular mechanisms potentially contributing to trichome formation in mustard.

High sodium-low potassium environment and hypertension.

The high sodium-low potassium environment of civilized people, operating on a genetic substrate of susceptibility, is the cardinal factor in the genesis and perpetuation of "essential" hypertension. The noxious effects begin in childhood, when habits of excess salt consumption are acquired at the family table, and are perpetuated by continuing habit and by increasing use of convenience and snack foods with artificially high concentrations of sodium and low levels of potassium. Present methods of food preparation leach out the protective potassium. Extradietary sodium chloride is a condiment not a requirement. Some primitive populations clearly preferred potassium chloride to sodium chloride. Chronic expansion of extracellular fluid volume induced by excess salt consumption causes the central and peripheral circulatory regulatory mechanisms to work at cross purposes, resulting in increased arterial pressure. The protective effect of potassium is dramatic and easily demonstrable in animals and man but its mechanism is not known. It cannot be entirely a direct effect on blood pressure because rats protected with extra potassium against a moderately high salt intake live much longer than control rats but have the same elevated blood pressures. In hypertension with a demonstrable "cause," the high sodium-low potassium environment makes a bad matter worse. In nature, feral man and his forebears were not confronted with excessive sodium and deficient potassium; indeed, the reverse was the case. Evolution has provided powerful mechanisms for conserving sodium and eliminating potassium, but no efficient physiologic mechanisms for conserving potassium and eliminating excess sodium. Most laboratory animal "control" diets contain an amount of sodium that fully suppresses aldosterone secretion, and the same is true of the "average" diet of the American people. Inadequate attention to dietary sodium and potassium makes many studies in both animals and man of uncertain validity. Internally, essential hypertension is an exceedingly complex mosaic of physiologic interactions. Viewed from outside, it is a disorder for which genetic material sets the stage; excessive sodium precipitates it and perpetuates it. Extra salt makes all forms more rapidly progressive and accelerates the onset of terminal events; extra potassium is everywhere protective. When an entire population eats excessively of salt, hypertension will develop among those genetically susceptible, but epidemiologic studies of salt versus blood pressure will not show a relation of salt to hypertension. This is the saturation effect. Low sodium diets are therapeutically effective but generally regarded as an impossible or an unnecessary nuisance. Effective prevention programs must be instituted at as early an age as possible. The efficacy of a prophylactic/therapeutic low sodium-high potassium diet should be weighed against the uncertain hazards of a lifetime of pill taking.

Studies on the traditional herbal anthelmintic Chenopodium ambrosioides L.: ethnopharmacological evaluation and clinical field trials.

Infusions and decoctions of the leaves, roots and inflorescences of the herbaceous shrub Chenopodium ambrosioides (American wormseed, goosefoot, epazote, paico) and related species indigenous to the New World have been used for centuries as dietary condiments and as traditional anthelmintics by native peoples for the treatment of intestinal worms. Commercial preparations of oil of chenopodium and its active constituent, ascaridol, obtained by steam distillation, have been and continue to be, used with considerable success in mass treatment campaigns. Ethnopharmacological studies in a community of Mayan subsistence farmers in Chiapas, Mexico, confirmed that decoctions containing up to 300 mg of dry plant material per kg body weight (MGKGW) were widely used and traditionally highly regarded in the treatment of ascariasis. However, therapeutic doses of up to 6000 MGKGW of powdered, dried plant had no significant anthelmintic effect on the adults of Necator, Trichuris of Ascaris. Gas-liquid chromatographic analyses of plant samples used consistently demonstrated the presence of ascaridol in the expected amounts. Possible origins of subjective belief in the efficacy of C. ambrosioides as used, may be related to the positive association of spontaneous, or peristalsis-induced passage of senescent worms immediately following a therapeutic episode. It is also possible that in the past varieties of the plant containing much more ascaridol were used. The results of these controlled field studies did not sustain widely held traditional beliefs, nor the value of therapeutic practices regarding this plant. It is, therefore, essential that all indigenous ethnomedical practices be objectively evaluated for efficacy and safety using appropriate protocols before being considered for adoptation or promotion in health care programs.(ABSTRACT TRUNCATED AT 250 WORDS)

Cutaneous allergy to mustard in a salad maker.

A case of allergic contact dermatitis to mustard (Brassica nigra) in a salad maker is reported. The sources of skin contact included a commercial salad cream, a vinegrette, and various members of the mustard family, Cruciferae. The Cruciferae family includes many salad vegetables and condiments which contain allergenic isothiocyanates. The extent of skin contact among salad makers and other food handlers may be significant, and sensitization to isothiocyanates from this large family of vegetables may be an important cause of food contact allergy in these individuals.

Food choices for lowering sodium intake.

Excessive intake of dietary sodium is one form of affluent or industrial society malnutrition. When combined with a genetic-based sodium sensitivity, this high sodium intake becomes a factor in the etiology of hypertension. Most dietary sodium comes from food, natural of processed. Indirect measures of discretionary sodium intake, that from the salt shaker in the kitchen or at the table, put it at a level of 25% to 50% in the United States. Direct measures on a small sample of subjects indicate that less than 10% of sodium intake is discretionary. Anyone who needs to reduce sodium intake must, therefore, make major changes in diet. This requires information on the sodium content of common foods, the availability of low sodium analogs of popular foods, and a variety of low sodium condiments to provide more choice for the individual.

Amyotrophic lateral sclerosis and parkinsonian syndromes in high incidence among the Auyu and Jakai people of West New Guinea.

Amyotrophic lateral sclerosis (ALS) and parkinsonism-dementia (PD) occur in the highest recorded incidence among primitive Auyu and Jakai people on the southern coastal plain of West New Guinea, in association with a heretofore unrecognized subacute, often recurrent, paralytic "poliomyeloradiculitis" (PMR). Ninety-seven cases of ALS, 19 cases of PD and 18 cases of PMR were recorded, with mean ages of onset of 33, 43, and 26, respectively, in a small affected population of only about 7000. The ecology, culture, and diet of the remote, primitive ALS- and PD-affected people are indistinguishable from that of their unaffected neighbors, except for a remarkable deficiency of calcium and magnesium in their soil and drinking water. The distribution of affected and nonaffected villages indicates that communicable infectious or genetic etiology is unlikely. As a result of the isolation and primitive technology, domestic animals (except dogs and pigs) were not found among the Auyu and Jakai, and no manufactured products (including metals, ceramics, textiles, petrochemicals, medicines, food additives, condiments, paints, dyes, or solvents) were available to them.

Anti-ulcer effect in rats of bitter cardamon constituents.

The effects of bitter cardamon (the fruit of Alpinia oxphylla), used as a medicine and a condiment, on HCl/ethanol-induced gastric lesions in rats were examined. The acetone extract at 50 mg/kg, p.o. significantly inhibited gastric lesions by 57.0%. An analysis of the active constituents in the acetone extract was performed using column chromatography. Nootkatone at 20 mg/kg, p.o. significantly inhibited gastric lesion. These results suggest that nootkatone, the sesquiterpenoid is an important constituent in stomach medications containing bitter cardamon.

Role of life-style and dietary habits in risk of cancer among seventh-day adventists.

The Seventh-Day Adventist population abstains from smoking and drinking; about 50% follow a lacto-ovo-vegetarian diet; and most avoid the use of coffee, tea, hot condiments, and spices. Existing data on cancer mortality in Seventh-Day Adventists clearly document mortality rates that are 50 to 70% of general population rates for most cancer sites that are unrelated to smoking and drinking. Several approaches to determining whether this reduced risk is due to the unique Seventh-Day Adventist life-style or selective factors related to who choses to become and remain a Seventh-Day Adventist are described. A comparison of the mortality experience of Seventh-Day Adventist and non-Seventh-Day Adventist physicians shows equal cancer mortality, which is consistent with the hypothesis that the apparent reduced risk of cancer death in all Adventists may be due to selective factors. However, the results of a small case-control study of colon and breast cancer among Adventists show statistically significant relative risks for colon cancer of 2.8 for past use of meat. For current food use, the significant relative risks are 2.3 for beef, 2.7 for lamb, and 2.1 for a combined group og highly saturated fat foods. This strongly suggests that the lacto-ovo-vegetarian diet may protect against colon cancer. However, the evidence linking diet to breast cancer is less clear. Because of the marked variability in dietary habits within the Seventh-Day Adventist population, they will be a productive group for further study of diet and cancer.

[Analysis of disorders of adolescent behavior at the Diagnostic- Referral Family Center in Szczecin].

As many as 120 subjects, directed in 1984-1988 to the Diagnostic-Consultative Family Centre in Szczecin, were studied due to behaviour disorders or penal acts. Thirteen (10.8%) juveniles were exempted from further studies, since they were diagnosed to have mental deficiency or encephalopathy. The rest was studied by means of diagnostic criteria for behaviour disorders according to DSM-III-R. Those complying with the criteria made up a group with Behaviour Distemper Syndrome (BDS)--74 persons (55 boys and 19 girls), while the others formed a group holding Single Behaviour Distemper (SBD)--33 persons (21 boys and 12 girls). Two age subgroups, 7-14 and 15-17 years, were isolated from each of the groups. Use was made of own questionnaire to collect data concerning factors that might induce the revealed behaviour disorders. Groups BDS and SBD were compared with regard to the type and incidence rate of respective signs of behaviour disorders, according to criteria DSM-III-R, and also the age, sex as well as social background, living environment, and hereditary encumberance, course of pregnancy and delivery, former psychophysical development, use of condiments, somatic disorders actually evidenced, parental and school environmental atmosphere and that of peers of the studied group.

Nutrition situation in metro Manila.

Summarizing the general characteristics of food consumption pattern and dietary status of the country's central urban region, the following are brought to focus: Metro Manila as compared to all urban and rural areas consumes less cereal grains but more sugars and fats and oils; consumes more of the high quality protein foods such as meat, poultry, eggs, milk and dried beans; and consumes less of fruits and vegetables. Availability and affordability of foods in the respective sectors could have affected to a large extent the magnitude of consumption differences. Although urban households had the advantage of a more varied and quantitatively higher food consumption, their nutrient intake was not really very different from rural households. Metro Manila still had a 13.7 percent calorie gap in its intake in 1987, and intake of ascorbic acid was notably lower than the rural sector. However, intake of thiamin and riboflavin as well as fat was appreciably higher in the metropolis. Briefly identifying the trends in food consumption with reference to six survey year periods from 1974 to 1987 (excluding 1984 and 1985), Metro Manila diet disclosed the following: increasing trend for sugars and syrups as well as dried beans, nuts and seeds and decreasing trend for cereal products, fruits and vegetables and condiments and others. There was a decrease in overall food consumption among Metro Manila households during the economic crisis that transpired in 1984 and 1985. However, there was a steady consumption of rice which was under price control, and a significant increase in the intake of some food items particularly green leafy and yellow vegetables which were among the cheapest food items available in Metro Manila markets. Some food adjustments were evidently resorted to during the period of economic dislocation showing the resiliency of the urban population. Metro Manila has been apparently drawing inordinately large amounts of the food supply from the rest of the country. There is therefore an "urban bias" of food supply to Metro Manila, that is, there is a much higher demand capacity for Metro Manila to draw food supply because of its higher income level and bigger population. The impact of this situation in terms of nutrition and food supply in the rural areas should be carefully examined so as not to put the rural areas in extreme disadvantage. FNRI nutrition surveys have shown that dietary energy inadequacy remains rampant in Metro Manila, while protein continues to be a marginal problem.(ABSTRACT TRUNCATED AT 400 WORDS)

Concentration of boron and other elements in human foods and personal-care products.

The element boron is ubiquitous in the environment. Comparatively low concentrations of dietary boron affect several aspects of mineral metabolism in animals and human beings. Therefore, it is appropriate to determine precisely the concentration of boron in human foodstuffs and absorbed, inhaled, or ingested nonfood substances. In this article, we report the analyzed concentrations of boron and other elements in selected foods (animal products, water, condiments, confections, fruits, tuberized roots, vegetables, cereal grains, and spices) and personal-care products (analgesics, antibiotics, decongestants, antihistamines, dental hygiene products, gastric antacids, and laxatives). We conclude that daily intake of boron usually differs considerably between any two individuals for three main reasons. First, concentration of boron in water varies considerably according to geographic source. At some locations, boron in drinking water and water-based beverages may account for most of the total dietary boron intake. Second, individual food preference greatly influences daily intake of boron. Fruits, vegetables, tubers, and legumes have relatively much higher concentrations of boron than do cereal grains or animal tissues and fluids. Third, boron was determined to be a notable contaminant or major ingredient of many personal-care products.
