“…The first, a pattern characterized by high intakes of vegetables and fruit, and also of whole grains and white meat or fish, was frequently named as a 'prudent', 'health' or 'health conscious' pattern (16) . The other is a culturally dependent 'traditional' pattern, reflecting ethnic differences in food preferences, as reported in North America (17)(18)(19) , Europe (20)(21)(22) , Asia (23)(24)(25)(26) and Latin America (27)(28)(29)(30) . Our study has also identified one traditional pattern composed of foods that are Brazilian staple foods, such as rice and beans.…”

“…8,[27][28][29][30][31] Most of the prospective and case-control studies reported significant increases in risk of colorectal cancer associated with the Western pattern. 8,27,[29][30][31] Although the precise definition of the Western pattern is difficult to establish, red meat, processed meat and eggs are consistently present in this pattern. According to Kesse et al 31 the drinker pattern was directly associated with colorectal cancer, replicating current evidence which strongly suggests that alcohol drinking is a risk factor for colon cancer, mainly among men.…”

A multisite case-control study on factor analysis and several cancer sites (mouth and pharynx, esophagus, stomach, colon, rectum, larynx, lung, breast, prostate, bladder, kidney) was conducted in Uruguay. The study included 3,528 cases and 2,532 controls. Factor analysis (principal components) was modeled among controls. This patterning method retained 4 factors per sex, labeled as prudent, drinker, traditional and Western. Odds ratios for these cancer sites, stratified by sex, were estimated using polytomous regression. Whereas the prudent pattern was mainly negatively associated with cancers of the upper aerodigestive tract, the Western pattern showed a strong increase in breast, lung and colon cancers. The study allowed for the reproducibility of the prudent, drinker and Western patterns, whereas the traditional pattern appears to be country specific. ' 2008 Wiley-Liss, Inc.Key words: dietary patterns; factor analysis; principal components; polytomous regression Uruguay is a developing country with high rates of cancer, showing age-adjusted incidence rates of 386.0 per 100,000 men and 303.2 per 100,000 women for all sites. 1 The most frequent sites are female breast (age standardized rate 114.9 per 100,000 women) and lung (Age standardized rate 76.5 per 100,000 men). Smoking and alcohol drinking are the major risk factors for frequent cancers like lung cancer and cancers of the upper aerodigestive tract in the Uruguayan population. Also, a diet low in vegetables and fruits and high in beef consumption are risk factors for digestive tract cancers. 2 Since foods are consumed together it could be suggested that the true effect of the diet may only be observed when all components are analyzed simultaneously. In fact, foods could act in synergism or be metabolized jointly. [3][4][5] Patterning methodologies, including factor analysis, may turn the analytical difficulties into an advantage. Factor analysis is used to reduce a large number of foods or nutrients to smaller number of factors for modeling purposes. 6 This analytic method was originated in the pioneer paper of Spearman in 1904. 7 Since then it has grown explosively mainly in psychology and social sciences. In 1992, Randall et al. 8 firstly applied this method in the study of food patterns and colon cancer. Since then, numerous studies on dietary patterns and diverse cancers have been published all over the World.On the basis of a large dataset of cases and controls, we decided to conduct a multisite study using factor analysis in a high-risk country such as Uruguay. The main objective was to estimate odds ratios (ORs) of several cancer sites by means of the application of the principal components method and multinomial regression.

“…Studies examining derived dietary patterns and cancer end points have, until recently, been rarer, but a number of recent studies have shown associations between dietary patterns and oral and pharyngeal (de Stefani et al 2005), prostate (Walker et al 2005), colorectal (Kim et al 2005) and lung cancers (Balder et al 2005), but no association between dietary patterns and breast (Fung et al 2005) and pancreatic cancers (Michaud et al 2005).…”

Whilst clinical deficiency of micronutrients is uncommon in the developed world, a suboptimal intake of certain micronutrients has been linked with an increased risk of chronic diseases such as CVD and cancer. Attention has therefore focused on increasing micronutrient status in order to theoretically reduce chronic disease risk. Increasing micronutrient status can involve a number of approaches: increasing dietary intake of micronutrient-rich foods; food fortification; use of supplements. Observational cohort studies have demonstrated an association between high intakes of micronutrients such as vitamin E, vitamin C, folic acid and β-carotene, and lower risk of CHD, stroke and cancer at various sites. However, randomised intervention trials of micronutrient supplements have, to date, largely failed to show an improvement in clinical end points. The discordance between data from cohort studies and the results so far available from clinical trials remains to be explained. One reason may be that the complex mixture of micronutrients found, for example, in a diet high in fruit and vegetables may be more effective than large doses of a small number of micronutrients, and therefore that intervention studies that use single micronutrient supplements are unlikely to produce a lowering of disease risk. Studies concentrating on whole foods (e.g. fruit and vegetables) or diet pattern (e.g. Mediterranean diet pattern) may be more effective in demonstrating an effect on clinical end points. The present review will consider the clinical trial evidence for a beneficial effect of micronutrient supplements on health, and review the alternative approaches to the study of dietary intake of micronutrients.
