Participants' Comments on Changes in the Revised Special Supplemental Nutrition Program for Women, Infants, and Children Food Packages: The Maryland Food Preference Study

The Institute of Medicine recommended changes in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food packages to help families from diverse populations establish more healthful dietary patterns. A cross-sectional study conducted during summer 2007 included interviews and focus groups with 223 WIC participants throughout Maryland. The objectives were to examine participants' responses to food package changes, to identify racial/ethnic differences, and to assess costs. All participants (100%) consumed fruits and vegetables. They preferred fresh for taste, but many endorsed canned and frozen for convenience and cost. Most women (56%) and children (69%) consumed whole milk and did not want reduced-fat milk. Few participants (13%) consumed soy products and most were uninterested in future consumption. Participants endorsed whole-wheat bread as more healthful and reported that they (59%) and their children (51%) would increase consumption if provided by WIC. Non-Hispanic participants preferred peanut butter over beans, Hispanic participants reported that they (44%) and their children (57%) would consume more beans (substituting for peanut butter) if provided by WIC. There were few differences in preferences between African-American and white participants. Hispanics differed from non-Hispanics in preference for beans and dislike of frozen and canned vegetables, suggesting the importance of choices. The proposed food packages were cost-neutral, except when extensive substitutions with soy products were allowed. By providing fruits and vegetables, reduced-fat options, and increased opportunities for nutrition education, the revised food packages may reduce the risk of obesity among low-income women, infants, and children.     

Positive influence of the revised Special Supplemental Nutrition Program for Women, Infants, and Children food packages on access to healthy foods

BackgroundThe Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has important potential for preventing diet-related disease in low-income children. WIC food packages were recently revised to offer foods that better reflect dietary recommendations for Americans.ObjectiveThis article reports on how implementation of the new healthier WIC food packages affected access of low-income populations to healthy foods (eg, whole grains, fruit and vegetables, and lower-fat milk).DesignA pre–post store inventory was completed using a standardized instrument to assess availability, variety, quality and prices of WIC-approved foods (65 food items). Stores were assessed before (spring 2009) and shortly after the new WIC package implementation (spring 2010).Participants/settingAll convenience stores and nonchain grocery stores located in five towns of Connecticut (N=252), including 33 WIC-authorized stores and 219 non-WIC stores.Statistical analyses performedThe healthy food supply score was constructed to summarize postrevision changes in availability, variety, prices of healthy foods, and produce quality. The effect of the WIC food package revisions was measured by differential changes in the scores for stores authorized to accept WIC benefits and stores not participating in WIC, including differences by neighborhood income. Multivariate multilevel regression models were estimated.ResultsThe 2009 introduction of the revised WIC food packages has significantly improved availability and variety of healthy foods in WIC-authorized and (to a smaller degree) non-WIC convenience and grocery stores. The increase in the composite score of healthy food supply varied from 16% in WIC convenience and grocery stores in higher-income neighborhoods to 39% in lower-income areas. Improved availability and variety of whole-grain products were responsible for most of the increase in the composite score of healthy food supply.ConclusionsDesigned as cost-neutral changes, the WIC food package revisions have improved access to healthy foods for WIC participants and society at large.     

Determinants and nutritional implications associated with low-fat food consumption

Objectives: the objective was to study determinants and nutritional implications associated with low-fat food consumption. Methods: a cross-sectional design was used, 5,000 military men were contacted and 1,852 participated. Using mailed questionnaires, the low-fat food consumption frequency was recorded and stratified in number of portions a day. The following low-fat food items were included: mayonnaise, yoghurt, milk, cheese, cottage cheese and meat. Results: the two most daily consumed low-fat foods were meat and yoghurt by, respectively, 21.7% and 17.3% of the participants. Only 3.5% consumed a daily portion of low-fat cheese, and 7.4% consumed one or more daily portions of low-fat milk. After adjustment, Body Mass Index (BMI), physical activity and non-smoking were associated with an increasing consumption of low-fat foods. Consumption of low-fat foods was associated with a decreased daily total and saturated fat intake, from respectively, 37.9 and 14.7 energy-percent for low consumption to 30.5 and 11.6 energy-percent for high consumption. This decrease was compensated by an increased intake in carbohydrates and sugar, respectively, 42.5 and 16.7 energy-percent to 46.5 and 22.6 energy-percent. Conclusions: age, BMI, physical activity and non-smoking were associated with an increasing consumption of low-fat foods. The fact that low-fat foods consumers had a higher intake of carbohydrates and proteins question the efficacy of these items in energy reducing programs.     

Food frequency intakes and sociodemographic factors of elderly Mexican Americans and non-Hispanic whites

A food frequency survey of 254 low-income, elderly (aged 60 to 96), free-living Mexican Americans and non-Hispanic whites was conducted as part of a larger study of the adjustment and health of older persons residing in a San Antonio barrio. Weekly intakes of selected foods were determined using the food frequency questionnaire from the Hispanic Health and Nutrition Examination Survey. We used t-tests to determine significance of difference in frequency of food consumption by ethnicity. The variance in consumption of selected foods was estimated with multiple regression analysis for the independent variables marital status, age, sex, education level, income, birthplace, and ethnicity. Ethnicity was the major variable influencing food intake. There were significant differences (p less than or equal to .05) between ethnic groups: Mexican Americans consumed eggs, poultry, legumes, organ meats, avocados/olives, flour tortillas, and sugar more frequently than non-Hispanic whites; they also used saturated fats in cooking more frequently than non-Hispanic whites; and they consumed skim milk, ice cream/ice milk, beef, all fruits or juices, all vegetables, breads, and oil/margarine less frequently than non-Hispanic whites. The results suggest that ethnicity plays a major role in predicting dietary patterns.     

Frequent consumption of milk, yogurt, cold breakfast cereals, peppers, and cruciferous vegetables and intakes of dietary folate and riboflavin but not vitamins B-12 and B-6 are inversely associated with serum total homocysteine concentrations in the US population

BACKGROUND: Elevated circulating total homocysteine (tHcy) is an independent risk factor for vascular diseases. OBJECTIVE: We investigated the relation between dietary intakes and serum tHcy in the US population. DESIGN: Data from the third National Health and Nutrition Examination Survey (1988-1994) were used to investigate the associations between food consumption frequency and dietary B vitamin intakes and serum tHcy in 5996 persons. RESULTS: Multivariate-adjusted tHcy concentrations were approximately 15.2% higher in subjects who never consumed milk than in those who consumed milk >30 times/mo, approximately 6.4% higher in subjects who never consumed yogurt than in those who consumed yogurt >15 times/mo, approximately 7.4% higher in subjects who never consumed cold breakfast cereals than in those who consumed cold breakfast cereals >30 times/mo, approximately 6.3% higher in subjects who never consumed peppers (includes red, yellow, green, and hot chili peppers) than in those who consumed peppers >30 times/mo, and approximately 16.5% higher in subjects who never consumed cruciferous vegetables than in those who consumed cruciferous vegetables >30 times/mo. Consumption of citrus fruit and juices, cheese, meats, coffee, or tea had no significant association with tHcy. Folate (beta=-0.0017, P for trend=0.004) and riboflavin (beta=-0.2851, P for trend=0.027), but not vitamin B-6 (beta=0.0505, P for trend=0.70) and cobalamin (beta=-0.0035, P for trend=0.58), were inversely related to serum tHcy after adjustment for confounders. CONCLUSIONS: In this population-based study, milk, yogurt, cold breakfast cereals, peppers, and cruciferous vegetables were inversely related to serum tHcy. This association may be explained by increased intakes of folate and riboflavin.     

Dietary sources of nutrients among rural Native American and white children

OBJECTIVE: To identify important food sources of energy, fiber, and major macro- and micronutrients among rural Native American and white children. DESIGN: In a 1997 cross-sectional study, food frequency questionnaire data were collected during in-person interviews with caregivers of young children. SUBJECTS/SETTING: Participants included a representative sample of 329 rural Native American and non-Hispanic white children aged 1 through 6 years living in northeastern Oklahoma. STATISTICAL ANALYSES: The percentage that each of 85 food items contributed to the population intake of 10 dietary constituents was calculated for the total sample and by age and race/ethnicity. Percentages are presented in descending rank order for foods providing at least 2% of the total sample intake. Z scores were used to assess age and racial/ethnic differences in food sources. RESULTS: Primary energy sources among study children were milk, cheese, white breads, salty snacks, nondiet soft drinks, hot dogs, candy, and sweetened fruit drinks. Diets showed poor food variety. With few exceptions (eg, milk, cheese, 100% orange juice, ready-to-eat cereals, peanuts/peanut butter, and dried beans), top sources of most dietary constituents were low-nutrient-dense high-fat foods and refined carbohydrates. Solid fruits and vegetables contributed minimally to nutrient and fiber intake. There were few differences in food sources by age or race/ethnicity. CONCLUSIONS: Among rural Native American and white children in northeastern Oklahoma, food sources of nutrients appear less healthful than found in national samples. Sugar-sweetened beverages, high-fat foods, and refined carbohydrates are displacing more nutrient-dense alternatives, increasing children's risk for childhood obesity, type 2 diabetes, and adult chronic disease.     

Commercial Baby Food Consumption and Dietary Variety in a Statewide Sample of Infants Receiving Benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children

Dietary variety and exposure to fruits and vegetables in infancy have been associated with nutritional benefits and later acceptance of these foods. The objective of this study was to examine the prevalence of fruit and vegetable commercial baby food consumption and its relation to dietary variety during infancy. A cross-sectional statewide telephone survey of 733 Maryland mothers and infants receiving benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) was conducted between July 2004 and July 2005. A 24-hour dietary recall was examined to assess infant dietary variety. Among infants from birth to age 5 months, 54% had consumed complementary foods in the past 24 hours; 60% received commercial baby foods. Among infants aged 6 to 12 months, 98% had consumed complementary foods in the past 24 hours; 81% received commercial baby foods. In the latter age range, the average daily number of different types of fruits and vegetables consumed was 1.5±1.2, range 0 to 6). In a multivariate model, infants aged 6 to 12 months who received commercial baby foods consumed a greater variety of fruits and vegetables (β=.54, 95% confidence interval 0.26-0.84; P<0.001) than infants who did not, characterized by a diet that was lower in white potatoes (14% vs 22%) and higher in dark-green (6% vs 5%) and deep-yellow (35% vs 10%) vegetables. Commercial baby food is consumed by a majority of WIC infants, although many mothers introduce it before the recommended age of 6 months. Among infants aged 6 to 12 months, commercial baby food is associated with dietary variety in fruits and vegetables. By encouraging consumption of fruits and vegetables after 6 months of age, either through the provision of commercial baby foods and/or education and resources related to the preparation of fruits and vegetables for infants, WIC can increase dietary variety and appropriate introduction of complementary foods among infants.     

Mothers Prefer Fresh Fruits and Vegetables Over Jarred Baby Fruits and Vegetables in the New Special Supplemental Nutrition Program for Women,Infants, and Children Food Package

ObjectiveThis study examined Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participant use and satisfaction with jarred baby foods, assessed preference for cash value vouchers (CVVs) for fruits and vegetables vs jarred baby foods, and examined whether preferences varied among selected ethnic groups.MethodsA survey of California WIC participants and statewide redemption data were used.ResultsParticipants reported high satisfaction with the CVV for fruits and vegetables and jarred baby foods, with statistically significant variation across ethnic groups. About two thirds of all participants reported a preference for CVVs for fruits and vegetables over jarred baby foods. Redemption data indicated declining redemption rates for jarred fruits and vegetables with increasing age of the infant across all ethnic groups.Conclusions and ImplicationsAlthough the addition of jarred fruits and vegetables to the food package for infants ages 6–11 months was well received, many caregivers want the option to choose between jarred foods and fresh fruits and vegetables.     

Food Sources of Energy and Nutrients among Children in the United States: National Health and Nutrition Examination Survey 2003–2006

Background: Recent detailed analyses of data on dietary sources of energy and nutrients in US children are lacking. The objective of this study was to identify food sources of energy and 28 nutrients for children in the United States. Methods: Analyses of food sources were conducted using a single 24-h recall collected from children 2 to 18 years old (n = 7332) in the 2003–2006 National Health and Nutrition Examination Survey. Sources of nutrients contained in foods were determined using nutrient composition databases. Food grouping included ingredients from disaggregated mixtures. Mean energy and nutrient intakes from the total diet and from each food group were adjusted for the sample design using appropriate weights. Percentages of the total dietary intake that food sources contributed were tabulated by rank order. Results: The two top ranked food/food group sources of energy and nutrients were: energy—milk (7% of energy) and cake/cookies/quick bread/pastry/pie (7%); protein—milk (13.2%) and poultry (12.8%); total carbohydrate—soft drinks/soda (10.5%) and yeast bread/rolls (9.1%); total sugars—soft drinks/soda (19.2%) and yeast breads and rolls (12.7%); added sugars—soft drinks/soda (29.7%) and candy/sugar/sugary foods (18.6%); dietary fiber—fruit (10.4%) and yeast bread/rolls (10.3%); total fat—cheese (9.3%) and crackers/popcorn/pretzels/chips (8.4%); saturated fatty acids—cheese (16.3%) and milk (13.3%); cholesterol—eggs (24.2%) and poultry (13.2%); vitamin D—milk (60.4%) and milk drinks (8.3%); calcium—milk (33.2%) and cheese (19.4%); potassium—milk (18.8%) and fruit juice (8.0%); and sodium—salt (18.5%) and yeast bread and rolls (8.4%). Conclusions: Results suggest that many foods/food groupings consumed by children were energy dense, nutrient poor. Awareness of dietary sources of energy and nutrients can help health professionals design effective strategies to reduce energy consumption and increase the nutrient density of children’s diets.     

Food habits of young and middle–aged women living outside the capital cities of Australia

Abstract: Young (18–22 years) and middle–aged (45–49 years) women living in urban and rural areas of New South Wales completed a brief food frequency questionnaire as part of a wider health survey. Urban women in both age groups consumed meat less frequently than women in rural areas, and women in the less populated rural areas were more likely to eat green and yellow vegetables and least likely to eat dried beans. There were few other geographic differences in food habits. Middle–aged women consumed reduced–fat milk, fruit, vegetables, fish, biscuits and cakes significandy more frequently, and rice, pasta, full–cream milk, fried food and take–away food less frequently than younger women. Smokers in both age groups consumed fresh fruit, vegetables and breakfast cereals significantly less frequendy than non–smokers, and women with low levels of habitual physical activity consumed fresh fruit and cereals less frequendy than more active women. The findings suggest that strategies aimed at changing eating behaviours should be age–group–specific and targeted specifically to smokers and less active women.     

Piecing together the crazy quilt of prenatal care

The failure to provide adequate prenatal care for low-income pregnant women in the United States and the effects of this failure on infant mortality are well known. Many studies have identified institutional barriers against access to care as a major cause. To overcome these barriers, Public Health District V, South Central Idaho, has created a comprehensive prenatal health care model that has almost tripled participation in its program during the first year of implementation and increased it again significantly during the second year. This decentralized pregnancy program has succeeded in getting all of the physicians offering obstetrical care in the district to serve low-income pregnant clients on a rotating basis. The new program provides pregnancy testing as well as financial screening services. Also, it has combined support services into one-stop-shopping clinics that include an innovative expansion of the Women, Infants and Children (WIC) Program of the U. S. Department of Agriculture. WIC food vouchers help attract clients into the prenatal care system and keep them coming. Enrichment of the duties of the public health nurse provides case coordination that pulls together the patchwork of medical and support services for the pregnant client.     

High-fat dairy food and conjugated linoleic acid intakes in relation to colorectal cancer incidence in the Swedish Mammography Cohort

BACKGROUND: High-fat dairy foods contain many potentially anticarcinogenic factors, including conjugated linoleic acid (CLA). However, few epidemiologic studies have specifically evaluated high-fat dairy food consumption, and none have evaluated CLA intake, in relation to colorectal cancer risk. OBJECTIVE: The aim of this study was to prospectively examine the associations of long-term high-fat dairy food consumption and CLA intake and the incidence of colorectal cancer. DESIGN: Our study population consisted of 60 708 women aged 40-76 y who participated in the Swedish Mammography Cohort. The women's consumption of high-fat dairy foods was assessed at baseline, which was from 1987 to 1990, and again in 1997. RESULTS: We ascertained 798 incident cases of colorectal cancer during an average 14.8 y of follow-up. After adjustment for age and other potential confounders, the women who consumed > or =4 servings of high-fat dairy foods/d (including whole milk, full-fat cultured milk, cheese, cream, sour cream, and butter) had a multivariate rate ratio of colorectal cancer of 0.59 (95% CI: 0.44, 0.79; P for trend = 0.002) when compared with the women who consumed <1 serving/d. Each increment of 2 servings of high-fat dairy foods/d corresponded to a 13% reduction in the risk of colorectal cancer (multivariate rate ratio: 0.87; 95% CI: 0.78, 0.96). For CLA, the multivariate rate ratio of colorectal cancer in a comparison of the 2 extreme quartiles of intake was 0.71 (95% CI: 0.55, 0.91; P for trend = 0.004). CONCLUSION: These prospective data suggest that high intakes of high-fat dairy foods and CLA may reduce the risk of colorectal cancer.     

Dairy food intake is positively associated with cardiovascular health: findings from Observation of Cardiovascular Risk Factors in Luxembourg study

Conflicting findings have been reported about dairy food consumption and risk for cardiovascular disease. Furthermore, few studies have examined dairy food intake in relation to cardiovascular health and the incorporation of lifestyle factors such as diet and physical activity. This study examined whether dairy food consumption was associated with cardiovascular health, recently defined by the American Heart Association. Data were analyzed from 1352 participants from the Observation of Cardiovascular Risk Factors in Luxembourg survey. A validated food frequency questionnaire was used to measure intakes of milk, yogurt, cheese, dairy desserts, ice cream, and butter. Seven cardiovascular health metrics were assessed: smoking, body mass index, physical activity, diet, total cholesterol, blood pressure, and fasting plasma glucose. A total cardiovascular health score (CHS) was determined by summing the total number of health metrics at ideal levels. It was hypothesized that greater dairy food consumption (both low fat and whole fat) would be associated with better global cardiovascular health, as indicated by a higher CHS. Total dairy food intake was positively associated with the CHS. Higher intakes of whole fat milk, yogurt, and cheese were associated with better cardiovascular health. Even when controlling for demographic and dietary variables, those who consumed at least 5 servings per week of these dairy products had a significantly higher CHS than those who consumed these products less frequently. Higher total whole fat dairy food intake was also associated with other positive health behaviors, including being a nonsmoker, consuming the suggested dietary intakes of recommended foods, and having a normal body mass index. Increased dairy food consumption was associated with better cardiovascular health.     

Alignment of California WIC Participant Preferences With Proposed WIC Food Package Recommendations

ObjectiveAssess alignment of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participant preferences with the National Academies of Sciences, Engineering, and Medicine WIC child food package recommendations and compare differences by race/ethnicity.MethodsCross-sectional examination of survey responses collected between January and May 2019 from 2,993 California WIC families with children aged 1–4 years.ResultsOver half of WIC participants (56.1%) wanted an increase in the amount allocated for fruits and vegetables. Many WIC participants (69.6%) thought the amount of juice offered by WIC was just right. Overall, the majority (91.0%) wanted to substitute more fruits and vegetables for juice. Most were satisfied with the amount of beans (78.4%), peanut butter (78.7%), and milk (88.3%). Preferences differed by race/ethnicity.Conclusions and ImplicationsPreferences of California WIC participants are highly aligned with the proposed National Academies of Sciences, Engineering, and Medicine changes for increasing fruits and vegetables. Notable differences by race/ethnicity suggest the need for more flexibility.     

Whole grains and risk of pancreatic cancer in a large population-based case-control study in the San Francisco Bay Area, California

Epidemiologic data suggest that consumption of whole-grain products may be inversely associated with risk of pancreatic cancer. Grain intake was examined in a population-based case-control study of pancreatic cancer in the San Francisco Bay Area (1995-1999). A 131-item semiquantitative food frequency questionnaire was administered to 532 cases and 1,701 controls. Odds ratios and 95% confidence intervals were computed as estimates of relative risk. Persons who consumed > or =2 servings of whole grains daily had a lower risk of pancreatic cancer than persons who consumed <1 serving/day (odds ratio (OR) = 0.60, 95% confidence interval (CI): 0.31, 1.2; trend-p = 0.04). Similar results were observed for brown rice (OR = 0.72, 95% CI: 0.44, 1.2; trend-p = 0.01) and tortillas (OR = 0.56, 95% CI: 0.35, 0.89; trend-p = 0.02). Consumption of doughnuts (> or =2 servings/week vs. <1 serving/month) conferred increased risk (OR = 1.8, 95% CI: 1.2, 2.7; trend-p = 0.003). Consumption of cooked breakfast cereals (> or =2 servings/week vs. <1 serving/month) was positively associated with risk (for oatmeal/oat bran, OR = 1.3, 95% CI: 1.0, 1.7; for other cooked breakfast cereals, OR = 2.1, 95% CI: 1.4, 3.3). Dietary fiber was inversely associated with risk (for highest quartile vs. lowest, OR = 0.65, 95% CI: 0.47, 0.89; trend-p = 0.02). These data provide some support for the hypothesis that consuming more whole-grain or high-fiber foods may reduce the risk of pancreatic cancer. Refined grains were not associated with risk.     

The time course of sensory-specific satiety

The time course of the changes in hedonic response following ingestion of three different foods was investigated. Normal weight, non-dieting female subjects rated the pleasantness of the appearance, smell, texture and taste of nine foods and then consumed as much as they wanted of cheese on cracker, tomato soup or orange jello. After this first course, subjects re-rated the pleasantness of the foods at 2, 20, 40 and 60 min. Following the 60 min rating, subjects were offered a second course of cheese on cracker or chocolate bar. For all sensory variables measured and for all foods consumed, the greatest decline in pleasantness occurred for the eaten food 2 min after consumption. For the food rate as most palatable (cheese on cracker) there was some recovery of pleasantness of the texture and taste over the hour. Intake in the second course was similar regardless of whether the food offered was different or the same as the food consumed in the first course. Since changes in the pleasantness of the foods occurred rapidly for all sensory variables studied and since the magnitude of these changes did not increase over time, it is concluded that the development of sensory-specific satiety is related primarily to the sensory stimulation accompanying ingestion as opposed to the postabsorptive effects of consuming these foods.     

Does Food Intake of Australian Toddlers 12–24 Months Align with Recommendations: Findings from the Australian Feeding Infants and Toddlers Study (OzFITS) 2021

(1) Background: Food-based dietary guidelines promote population health and well-being through dietary patterns that reduce chronic disease risk while providing adequate energy and nutrients. In Australia, recommended dietary patterns based on servings per day from the five food groups—fruits, vegetables, cereals and grains, meats and alternatives, and dairy—have been developed for toddlers 1–2 years of age. However, no study has assessed the intake of the five food groups in this age group nationally. (2) Aim: To compare daily servings and the percentage of energy from the five food groups and discretionary foods in toddlers 1–2 years old to the Australian Dietary Guidelines. (3) Methods: Dietary intake was assessed using a one-day food record for 475 toddlers. (4) Results: Apart from fruit and dairy, servings of the five food groups were below the recommendations. Two-thirds of toddlers did not consume enough vegetables, and only 10% consumed the recommended number of servings for cereals and grains. On average, toddlers consumed only half the recommended servings of meat and alternatives. Nearly all toddlers (89%) consumed discretionary foods, which accounted for ~12% of total energy. Forty-five percent of toddlers received breastmilk. On average, breastfed toddlers consumed fewer servings from the five food groups than non-breastfed toddlers. Dairy contributed 20% of daily energy in all toddlers; however, this food group accounted for 13% in breastfed and 32% in non-breastfed toddlers on the day of the food record. (4) Conclusions: Compared to the recommendations, alignment with the servings of the five food group foods was not achieved by most toddlers, except for fruit and dairy. Discretionary foods may have displaced nutritious family foods. Consistent with Australian Infant Feeding Guidelines, many toddlers in this study continued to receive breastmilk but the recommended dietary patterns do not include breastmilk. Dietary modeling, including breastmilk as the primary milk source, is urgently needed, along with practical advice on incorporating breastmilk in a toddler’s diet while optimizing food consumption.     

Development of a food frequency questionnaire in a probabilistic sample of adults from Niterói, Rio de Janeiro, Brazil

With the purpose of generating a list of foods for a food-frequency questionnaire, data from 24h dietary recalls on a typical day from a probabilistic sample of 1,724 adults of Niterói, Rio de Janeiro, Brazil, were analyzed. The frequency of food intake, the total intake of energy and macronutrients and the relative contribution of each food item to total energy and macronutrient intake were calculated. The most frequently reported food items (> 50% of adults) were rice, coffee, beans, refined canesugar, and bread. Whole milk was consumed more frequently then skimmed milk or semi-skimmed milk. Beef was consumed by more adults than chicken, pork or fish. Approximately 90% of energy and macronutrients intake was explained by 65 food items. The list of food items generated in the present analysis is similar to those found in other samples of adults from urban areas in Brazil. It may be possible to generate a core list of common foods with addition of regional foods to be used nationally in urban areas of the country.     

Aflatoxin M1 Levels in Commonly Consumed Cheese and Yogurt Samples in Ankara, Turkey

The potential hazardous human exposure to aflatoxin M₁ via consumption of milk and milk products has been demonstrated by several workers. Considering its risk to human health, determination of aflatoxin M₁ levels in dairy products is important. Since there are limited data available on the occurrence of aflatoxin M₁ levels in dairy products in Turkey, the aim of the present study was to investigate the presence of this toxin in various types of commonly consumed cheese and yogurt samples in the capital city of Turkey—Ankara. For this purpose, 39 samples of cheese and 40 samples of yogurt were randomly collected from supermarkets in Ankara. Aflatoxin M₁ levels were determined by a competitive enzyme-linked immunosorbent assay (ELISA) kit. Aflatoxin M₁ was detected in 11 cheese samples ranging from 78.20 to 188.44 ng/kg. Thirty-two of the 40 yogurt samples had aflatoxin M₁ levels between 61.61 and 365.64 ng/kg. The results of this study indicated the importance of continuous surveillance of commonly consumed cheese and yogurt samples for aflatoxin M₁ contamination in Turkey.
