A high prevalence of obesity in a diabetic population: results of a survey of food patterns in 252 patients in a 2 year period.

Dietary patterns were reviewed and correlated with the patients' clinical details in 252 patients seen at the initial visit to a diabetic clinic of a major metropolitan teaching hospital. Except in the subgroup of male patients with insulin-dependent diabetes, there was an extremely high prevalence of obesity, especially in females (70% greater 120% of standard weight; 28% greater than 150%). Traditional 'low-carbohydrate' diets were commonly found irrespective of ethnic origin, particularly in those individuals who had received previous dietary education. This study highlights the urgent need for public health education programmes in order to try to prevent the development of obesity since therapy remains unsatisfactory once it is established.

Historical assessment of nutrition studies using only African-American study subjects: gender, socioeconomic status, and geographic location.

While the African-American community has disproportionate rates of morbidity and mortality from chronic diet-related diseases, few studies have examined demographically the spectrum of these outcomes in the population. The purpose of this study is to determine the extent to which published scientific literature has examined African-American samples with sufficient specificity to identify nutrition problems in subsets of the population. Age, gender, socioeconomic status, geographic location, and sample size are used to examine study questions. In addition, the United States Department of Agriculture (USDA) Continuing Survey of Food Intakes for Individuals (CSFII) 1994-1996 is used to illustrate how evaluating nutrient variables by demographic indicators provides insights into the heterogeneity of nutrient intake patterns among African Americans. Relative to the adequacy of scientific investigation into these issues, a review of twenty-nine studies conducted from 1970 to the present demonstrates bias in gender, income, and sample size for African-Americans-only dietary research samples. Relative to identifying dietary patterns that do not meet US dietary guidelines, pervasive patterns that persist across income groups were found, indicating the need for nutrition education programs at all levels. Although there are science based diet information available, it does not seem to have reached the African-American community in numbers sufficient to be reflected in dietary changes as reported by surveys. This research demonstrates the need for detailed studies highlighting these issues, as well as the production of culturally appropriate nutrition education materials and methods that will be effective in reaching this population.

The burden of disease attributable to nutrition in Europe.

OBJECTIVE: This review examines the extent to which differences in nutrition could explain the diversity of health in Europe and how dietary patterns might contribute to the overall burden of disease in the region. SETTING: Europe. DESIGN: Between-country variations and time trends in dietary and health patterns in Europe are described, taking into account recent evidence on east-west mortality differentials. Existing information on the contribution of dietary factors to the overall burden of disease in Europe and to the burden of cardiovascular diseases and cancer is then reviewed, including a discussion of the methodological challenges that face those seeking to quantify this burden accurately. RESULTS: While evidence from ecological data have long suggested that variations in health patterns in Europe may be at least partly attributed to differences in dietary intake, recent research into the major risks to disease, disability and death is confirming the importance of poor nutrition to major health problems and overall disease burden in Europe. Findings from the Global Burden of Disease 2000 study suggest that 4.4% of the overall burden of disease in the region could be attributed to low fruit and vegetable intake, and 7.8% to overweight and obesity. CONCLUSIONS: The burden of disease attributed to poor nutrition in Europe appears to be substantial and probably underestimated. However, better quantification of the contribution of nutrition to the region's burden of disease awaits further research to assess the dietary intake of Europeans and to explore the relationship between nutritional factors and health outcomes in diverse parts of Europe.

Predictors of weight gain in a Mediterranean cohort: the Seguimiento Universidad de Navarra Study 1.

BACKGROUND: High consumption of sugar-sweetened drinks has been associated with weight gain and obesity in the United States. This trend may also be affecting populations with different eating patterns who increasingly are adopting typical US dietary patterns. OBJECTIVE: We assessed whether the consumption of sweetened drinks and other food items increased the likelihood of weight gain in a Mediterranean population. DESIGN: This was a prospective cohort analysis of 7194 men and women with a mean age of 41 y who were followed-up for a median of 28.5 mo with mailed questionnaires. Dietary exposure was assessed with a previously validated semiquantitative food-frequency questionnaire. RESULTS: During follow-up, we observed that 49.5% of the participants increased their weight (x weight gain: 0.64 kg; 95% CI: 0.55, 0.73 kg). In the participants who had gained > or =3 kg in the 5 y before baseline, the adjusted odds ratio of subsequent weight gain for the fifth quintile compared with the first quintile of sugar-sweetened soft drink consumption was 1.6 (95% CI: 1.2, 2.1; P for trend = 0.02). This association was absent in the participants who had not gained weight in the 5-y period before baseline. The consumption of hamburgers, pizza, and sausages (as a proxy for fast-food consumption) was also independently associated with weight gain (adjusted odds ratio for the fifth compared with the first quintile = 1.2; 95% CI: 1.0, 1.4; P for trend = 0.05). We also found a significant, but weaker, association between weight gain and both red meat and sweetened fruit juice consumption. CONCLUSION: In a Mediterranean cohort, particularly in the participants who had already gained weight, an increased consumption of sugar-sweetened soft drinks and of hamburgers, pizza, and sausages was associated with a higher risk of additional subsequent weight gain.

Diet, genes and disease: implications for nutrition policy.

There is extensive evidence to show that there is considerable variation in diet and disease patterns in Europe and that many of the dietary patterns are predictive of chronic disease. Increasingly, there is evidence that this dietary effect is mediated by genetic background. The present paper examines the role of polymorphisms within three genes, those responsible for the synthesis of apoE, 5,10-methylenetetrahydrofolate reductase (MTHFR) and PPARgamma. There is clear evidence to support the concept that the diet-disease link is moderated by genetic variation. The paper then considers whether this moderating effect will have implications for dietary recommendations. In the formulation of dietary reference values it has long been recognized that these values cannot cover the needs of all individuals. By setting the upper level at the mean value +2 sd, the needs of 97.5% of the population are covered. Setting a hypothetical scenario of a nutrient requirement of 200 mg/d and a polymorphism with an allelic frequency in the general population in the range of 0, 10, 20 and 30% that causes an increased nutrient requirement of 25%, there was no evidence that the traditional approach requires revision. Whilst it is recognized that genetic variability may not influence population goals, genetic variability will have to be taken into account in the clinical nutrition management of disease. To knowingly assign a patient to life-long treatment with a diet that for genetic reasons will have no success is both unethical and uneconomical. Once accepted in clinical nutrition, the diet-gene interaction will filter into the prevention of disease in public health nutrition.

The nutritional status of subjects with anorexia nervosa.

This study characterized the dietary pattern of 25 subjects with anorexia nervosa from a diet history. The patients mean age was 18 +/- 5 years and mean weight loss from preillness weight was 26%. Diets of anorectics were found to be significantly lower in total energy, reflecting a disturbance in nutrient intake when data were compared to a normal population. The percentage of energy derived from macronutrients was higher for protein and lower for concentrated carbohydrates, but total carbohydrates and lipids were found similar to the ones observed in normal subjects. Dietary intake of calcium, iron, thiamin, riboflavin, niacin and ascorbic acid of anorectics were significantly lower than in normal subjects. Such a particular pattern was paralleled by high serum cortisol levels and circadian cortisol cycle, low morning glycemia, high carotenemia, hypokaliemia and hyperalbuminemia. Results are discussed on the basis of the nutritional adequacy of the anorexia nervosa dietary pattern and its relationship with some aspects of the symptomatology of the disease.

How well do Australian women comply with dietary guidelines?

OBJECTIVE: To investigate the proportion of middle-aged Australian women meeting national dietary recommendations and its variation according to selected sociodemographic and behavioural characteristics. DESIGN: This cross-sectional population-based study used a food-frequency questionnaire to investigate dietary patterns and compliance with 13 commonly promoted dietary guidelines among a cohort of middle-aged women participating in the Australian Longitudinal Study on Women's Health. SETTING: Nation-wide community-based survey. SUBJECTS: A total of 10,561 women aged 50-55 years at the time of the survey in 2001. RESULTS: Only about one-third of women complied with more than half of the guidelines, and only two women in the entire sample met all 13 guidelines examined. While guidelines for meat/fish/poultry/eggs/nuts/legumes and 'extra' foods (e.g. ice cream, chocolate, cakes, potatoes, pizza, hamburgers and wine) were met well, large percentages of women (68-88%) did not meet guidelines relating to the consumption of breads, cereal-based foods and dairy products, and intakes of total and saturated fat and iron. Women working in lower socio-economic status occupations, and women living alone or with people other than a partner and/or children, were at significantly increased risk of not meeting guidelines. CONCLUSIONS: The present results indicate that a large proportion of middle-aged Australian women are not meeting dietary guidelines. Without substantial changes in their diets, and help in making these changes, current national guidelines appear unachievable for many women.

Nutrition and the incidence of stress fractures in ballet dancers.

The effects of nutrition on the incidence of stress fractures among classical ballet dancers were studied. Ten dancers with stress fractures were compared with a group of dancers without stress fractures and a group of nondancing control subjects. Subject pairs were matched for age, weight, and height. Specific nutrient intake and eating patterns were thus isolated to determine if dietary patterns could account for the incidence of stress fractures among these dancers. The majority (80%) of the 10 dancers with recent stress fractures had weights less than 75% of ideal (p less than 0.05) and showed a greater incidence of eating disorders (p less than 0.05). This group also showed a lower fat intake and a higher intake of low-calorie food (p less than 0.05). Menstrual patterns and bone density studies of the wrist, foot, and spine did not differ among the three groups, showing that stress fractures were significantly associated with a more-restrictive diet.

Evaluation of the population distribution of dietary contaminant exposure in an Arctic population using Monte Carlo statistics.

Organochlorines and heavy metals have bioaccumulated in Arctic wildlife, which is an important food source for the Inuit. In this study, we have developed a statistical model to describe the population distribution of contaminant exposure and the usual intake of the high-end contaminant consumers. Monte Carlo methods are used to account for variations due to seasonal dietary pattern and contaminant concentrations. Distribution of the dietary intake of the contaminants of most concern-mercury, polychlorinated biphenyls (PCBs), chlordane, and toxaphenes-are described. Over 50% of the residents had dietary exposure levels exceeding the tolerable daily intake or provisional tolerable daily intake for Hg, toxaphene, and chlordane (83, 91, and 71% for men and 73, 85, and 56% for women, respectively). The high-end consumers (i.e. the 95th centile) have intake levels 6 times higher than the provisional tolerable weekly intake of Hg, and over 20 times the tolerable daily intake of chlordane and toxaphene. Assessment of health risks of the relative high contaminant exposure in this community must also consider the nutritional, economical, cultural, and social importance of these traditional foods. A comprehensive risk management scheme has yet to be developed.

Nutrient intakes of middle-aged men and women in China, Japan, United Kingdom, and United States in the late 1990s: the INTERMAP study.

The purpose of the study was to compare nutrient intakes among Chinese, Japanese, UK, and US INTERMAP samples, and assess possible relationships of dietary patterns to differential patterns of cardiovascular diseases between East Asian and Western countries. Based on a common Protocol and Manuals of Operations, high-quality dietary data were collected by four standardized 24-h dietary recalls and two 24-h urine collections from 17 population samples in China (three samples), Japan (four samples), UK (two samples), and USA (eight samples). There were about 260 men and women aged 40-59 years per sample--total N=4680. Quality of dietary interview and data entry were monitored and enhanced by extensive systematic ongoing quality control procedures at local, country, and international level. Four databases on nutrient composition of foods from the four countries were updated and enhanced (76 nutrients for all four countries) by the Nutrition Coordinating Center, University of Minnesota, in cooperation with Country Nutritionists. The mean body mass index was much higher for Western than East Asian samples. Macronutrient intakes differed markedly across these samples, with Western diet higher in total fat, saturated and trans fatty acids, and Keys dietary lipid score, lower in total carbohydrate and starch, higher in sugars. Based on extensive published data, it is a reasonable inference that this pattern relates to higher average levels of serum total cholesterol and higher mortality from coronary heart disease in Western than East Asian populations. The rural Chinese diet was lower in protein, especially animal protein, in calcium, phosphorus, selenium, and vitamin A. Dietary sodium was higher, potassium lower, hence Na/K ratio was higher in the Asian diet, especially for Chinese samples. This pattern is known to relate to risks of adverse blood pressure level and stroke. At the end of the 20th century, East Asian and Western diets remain significantly different in macro- and micronutrient composition. Both dietary patterns have aspects that can be regarded, respectively, as adverse and protective in relation to the major adult cardiovascular diseases. In both Asian and Western countries, public efforts should be targeted at overcoming adverse aspects and maintaining protective patterns for prevention and control of cardiovascular diseases.

The food of Near East, North West and Western African regions.

Among the countries that can be classified as Near East Africa, North West Africa, and Western Africa, there is a great diversity of foods and dietary patterns. Prevalence of undernourishment as defined by FAO using dietary energy supply data, varies dramatically among these countries, with Tunisia in the lowest prevalence category (<2.5%), and Sierra Leone in the highest prevalence category (>35%). Throughout the 1960's, the dietary energy supply of North West African and Western African countries was similar. However, since the 1970s a great and consistent improvement has been seen in North and North West African countries. Both the proportion and number of undernourished in North Africa is now very similar to that of North America. Oil use, energy from fat, and protein from plant versus animal sources account for a large part of the food pattern differences between countries in these regions. Using Tunisia and Sierra Leone as examples again, dietary diversity as measured by the percentage of energy from foods other than starchy staples, is about 50% in the former, while in the latter, it is only 36%. Fatty fruits such as olives, cocoa and palm fruit have a special role in both the diet and the economies of the region.

Nutrition and longevity - diet in centenarians.

BACKGROUND: Nutrition plays a central role in the biological mechanisms that shape aging, health span, and longevity. Micronutrients—including vitamins, trace elements, and polyphenols—support genomic stability, mitochondrial integrity, and antioxidant defense, while dietary patterns rich in plant-based foods modulate inflammation, metabolic regulation, and epigenetic processes. Centenarian populations consuming Mediterranean, Okinawan, Nordic, and Nicoyan diets offer a natural model for understanding how nutrient-rich, minimally processed foods, moderate caloric intake, and balanced lifestyles interact with molecular pathways to extend functional life. MAIN BODY: This review synthesizes current evidence on how micronutrients influence DNA repair, oxidative stress reduction, and mitochondrial protection, particularly through the actions of vitamins C and E, niacin-dependent PARP activity, folate-mediated methylation, and metal cofactors involved in antioxidant enzymes. Plant-based diets rich in fiber and polyphenols enhance microbial diversity and promote beneficial taxa such as Akkermansia and Bifidobacterium, supporting gut barrier integrity and immune balance. Caloric restriction and intermittent fasting activate nutrient-sensing pathways, including AMPK and sirtuins, reduce mTOR activity, and stimulate autophagy, collectively improving cellular resilience. Findings from centenarian regions highlight the convergence of lifestyle, nutrition, and cultural practices that reduce systemic inflammation, maintain metabolic flexibility, and support healthy aging trajectories. CONCLUSIONS: Diet emerges as a decisive modifiable determinant of lifespan and health span. The convergence of molecular nutrition, microbiome composition, and traditional dietary habits underlies the exceptional longevity observed in centenarian populations. Future research should integrate nutrigenomics, metabolomics, and microbiome profiling to clarify causal mechanisms and guide precision nutrition strategies for aging societies.

Are child eating patterns being transformed globally?

OBJECTIVE: To examine the extent to which child dietary patterns and trends are changing globally. RESEARCH METHODS AND PROCEDURES: Diets of children 2 to 19 years of age were studied with nationally representative data from Russia and the United States, nationwide data from China, and regional data from metropolitan Cebu, Philippines. Twenty-four-hour dietary recalls were examined at several points in time to examine trends in calories consumed away from home, snacking behavior, and soft drink and modern fast food consumption. Urban-rural trends were compared. RESULTS: U.S. and Cebu youth consume more than one-third of their daily calories and a higher proportion of snack calories from foods prepared away from home. In contrast, away from home food consumption is minimal in Chinese and Russian children. U.S. and Cebu youth consume about one-fifth of their total daily energy from snacks, but snacks provide a much lower proportion of energy in Russia ( approximately 16%) and China (where snacks provide only approximately 1% of energy). Fast food plays a much more dominant role in the American diet ( approximately 20% of energy vs. 2% to 7% in the other countries), but as yet does not contribute substantially to children's diets in the other countries. Urban-rural differences were found to be important, but narrowing over time, for China and Cebu, whereas they are widening for Russia. DISCUSSION: This research suggests that globalization of the fast food and other modern food sectors is beginning to affect child eating patterns in several countries undergoing nutrition transition. However, the contribution of fast food and soft drinks to the diet of children remains relatively small in China, Russia, and Cebu, Philippines, relative to the United States.

Seasonal variation in the dietary adequacy of highland Pwo and Sgaw Karen (Thailand).

The present report describes seasonal variability (postharvest, preharvest, harvest) in the dietary adequacy of highland Karen farmers (38 Pwo and 51 Sgaw mother-weaned child pairs) in Thailand. Both the Pwo and Sgaw exhibit little functionally significant seasonal variation in either energy or protein intakes, although there is significant seasonal variation in other nutrients. Sgaw Karen mothers and their weaned children had significantly higher intakes of energy, protein, and seven nutrients than their Pwo counterparts during all three study seasons. The cause of this difference appears to be related to the better socioeconomic status of the Sgaw, as well as to differences in belief systems that result in a greater utilization of wild resources by the Sgaw. There were no significant differences in energy intakes between mothers and their children in either ethnic group, while children tended to have significantly greater intakes of protein but significantly lower intakes of other nutrients. These differences in dietary patterns appear to be due to differences in dietary density and dietary preferences, rather than to foods being differentially directed towards adults.

Dietary fats and cancer.

The mono-unsaturated non-essential fatty acid oleic acid (OA) has been shown to stimulate malignant cell proliferation in culture significantly. In contrast, the essential fatty acids (EFAs) linoleic acid (LA) and alpha-linolenic acid (ALA) and their longer chain metabolic derivatives have been shown to have potent proliferation suppressive effects on malignant cells in culture. OA is normally synthesized in the body and present in most vegetable oils and therefore also in most experimental polyunsaturated fatty acid diets used for assessing the effects of dietary fatty acids on tumorigenesis in rats. Dietary OA could therefore specifically account for the general observation that diets containing polyunsaturated fatty acids (PUFAs) are tumorigenic (1). It has been repeatedly demonstrated that many EFAs and EFA metabolites suppress proliferation of a wide range of malignant cells in culture. These cytotoxic effects of EFAs do not inhibit the proliferation of nonmalignant cultured cells. The EFAs which have proliferation-suppression activities are components of cell membranes and many are also eicosanoid precursors. It is proposed that the membranes of malignant cells are inherently unstable. Thus the EFAs may have effects which either fluidise or stabilise these membranes. This results in either cytolysis or inhibition of proliferation. The relative quantities of the different EFAs may be critical for these effects. Eicosanoid metabolites may further compound these actions. It is suggested that one pathway for these actions could be a metabolic imbalance of EFA metabolites and their eicosanoid products. This would arise due to a combination of inhibited desaturase enzymes and a concomitant free cellular supply of dietary arachidonic acid (AA). This imbalance also could be causally involved in the promotion of malignancy. A simple procedure, which only involves dietary supplementation with gamma-linolenic acid (GLA) and eicosapentaenoic acid (EPA), is proposed as prophylaxis against the possible tumorigenic effect of dietary fats. "By some estimates, as much as 90% of all cancer in humans has been attributed to various environmental factors, including diet. The evidence reviewed by the committee suggests that cancers of most of the major sites are influenced by dietary patterns. The committee concluded that of all the dietary components it studied, the combined epidemiological and experimental evidence is most suggestive for a causal relationship between fat intake and the occurrence of cancer" - (1).

Lean and weight stable: behavioral predictors and psychological correlates.

OBJECTIVE: To examine behavioral characteristics associated with being lean and weight stable during adulthood. RESEARCH METHODS AND PROCEDURES: Participants included 165 white married couples who were part of a larger longitudinal study. Participants' height and weight were measured on three occasions at 2-year intervals. Men and women were classified as being lean and weight stable (the target group) if they had a BMI < 25 at baseline and maintained their weight within 5% of baseline at 2nd and 4th year follow-up. Individuals not fulfilling these criteria were included in the comparison group. Group differences in background characteristics including childhood weight status, BMI at each occasion, dieting history, and mental and physical health history were examined. In addition, multiple measures of dietary intake and physical activity were obtained and used to predict the likelihood of being in the target group. RESULTS: Men (N = 22) and women (N = 36) in the target group had lower mean BMI scores at each occasion, were less overweight during childhood, were less likely to have dieted in the past year, and rated themselves as being more healthy than men and women in the comparison group. No differences were identified in mental health. Relative to the comparison group, women in the target group reported higher levels of physical activity and higher levels of physical activity among their spouses, and men in the target group reported healthier dietary patterns. DISCUSSION: Results from this study suggest that being lean and weight stable in adulthood is linked to childhood weight status in combination with dietary and activity patterns during adulthood.

Cross-cultural variations and changes in food-group intake among elderly women in Europe: results from the Survey in Europe on Nutrition and the Elderly a Concerted Action (SENECA).

To study cross-cultural variations and changes in intake of food groups in elderly Europeans, longitudinal data on food-group intake from Danish (n = 55), Dutch (n = 65), Swiss (n = 79), and Spanish (n = 46) female participants in the Survey in Europe on Nutrition and the Elderly a Concerted Action (SENECA) were compared. Participants were born between 1913 and 1918. Information on food intake was obtained with use of the same diet-history method at all sites and in both 1988-1989 and 1993. Actual food intake was coded according to the Eurocode system, the applicability of which for European multicenter studies was evaluated in this study. All participants, regardless of site, reported consumption of milk, grain products, and vegetables, and almost all ate meat, fats, and fruit. Fewer women ate eggs, fish, and sugar. The variations between the sites were in the food groups consumed and the types of foods within the groups. Spanish women appeared to have the most healthy food-intake pattern. They also had more changes in their dietary pattern than did women in the other countries. The Eurocode was adequate for describing the actual food intake of elderly women in four European towns. The coding for meat, however, was ambiguous and should be revised.
