Adherence to dietary patterns among cancer survivors in the United States

This study investigates the association between a previous history of cancer and adherence to dietary patterns in the United States. This cross-sectional study included 13,751 adults ages 18 and older from the Third National Health and Nutrition Examination Survey (NHANES III). We used principal component analysis (PCA) to identify major dietary patterns. We used linear regression models to assess the association between previous cancer history and adherence to dietary patterns. A previous history of cancer was not associated with adherence to the prudent dietary pattern. The western dietary pattern was positively related to a previous history of cancer (b = 0.13, CI 0.05 to 0.20, p = 0.001; badj = 0.23, CI 0.15 to 0.31, p = <0.001); and the traditional dietary pattern was negatively related to a previous history of cancer (b = − 0.58, CI −0.65 to –0.51, p = <0.001; badj = −0.22, CI −0.29 to –0.15, p = <0.001). The alcohol dietary pattern was positively associated with a previous history of cancer only before adjusting for possible confounders (b = 0.13, CI 0.06 to 0.20, p = <0.001; badj = 0.03, CI 0.03 to 0.10, p = <0.365). Our findings suggest that cancer survivors do not follow a healthy dietary pattern and need guidance to adopt and maintain a healthy diet. The promotion of healthy dietary behaviors may improve the length and the quality of life of this population.

Effects of dietary acculturation to Malaysian who migrate to the region of Riyadh, Saudi Arabia

Migration is a global phenomenon in modern world. The objective of this study was to evaluate the effects of dietary acculturation to Malaysians who migrate to the region of Riyadh, Saudi Arabia compared to their traditional dietary patterns in Malaysia. About 122 healthy Malaysians immigrating respondents were conveniently recruited for this study and their dietary patterns before and after migration were evaluated using specific self-administered questionnaire. All the data were then analyzed using the Statistical Package for the Social Sciences (SPSS) Windows program version 17.0. The results showed that the frequency of respondents who irregularly take their meals is increased from 9.8% (in Malaysia) to 41.8% (in Saudi Arabia). Before migration, about 95.1% to 98.4% of the respondents took their breakfast, lunch and dinner every day but after migration, only 52.5% to 86.9% of them took breakfast, lunch and dinner every day. All demographic factors which are; gender, marital status, age range, level of education, occupation in Saudi Arabia, length of stay in Saudi Arabia and factor of stay with whom in Saudi Arabia showed significant (P<0.05) effects on regularity of meals intake in Saudi Arabia. The study showed that Malaysian immigrants in Saudi Arabia affected with dietary acculturation.

The association between dietary patterns with severity of coronary artery stenosis, serum leptin-to-adiponectin ratio, and some related risk factors in patients with coronary artery disease.

This research aimed to investigate the association between dietary patterns with severity of coronary artery stenosis, serum leptin-to-adiponectin ratio, and some related risk factors in patients with coronary artery disease referred for coronary angiography. This cross-sectional study was carried out on 191 men patients with known coronary disease aged 40-70years whom were admitted to angiography ward of Ahvaz teaching hospital, Ahvaz, Iran. Dietary patterns were investigated using 161-item semi-quantitative food frequency questionnaire. Anthropometric indices; blood pressure; serum levels of adiponectin and leptin, blood levels of glucose, total cholesterol, HDL-C, LDL-C, and triglycerides were measured. Patients were categorized based on the severity of coronary artery disease [number of vessel involved-single (VD1), double (VD2), triple (VD3)]. Three major dietary patterns were recognized using a factor analysis approach: western, healthy, and traditional patterns. Linear regression analysis demonstrated that there was a negative association between healthy dietary pattern with LDL-C, total cholesterol, and triglycerides. This dietary pattern was positively related to HDL-C. Both traditional and western dietary patterns were related to fasting blood glucose level and lipid profile. General obesity was positively associated with traditional and western dietary patterns. There was a positive relationship between central obesity with traditional and western dietary patterns, but a negative association was reported between the healthy dietary pattern and central obesity. Traditional and western dietary patterns demonstrated a significant positive relationship with serum leptin levels and ratio of L/A, and an inverse relationship with adiponectin. Healthy dietary pattern had a significant negative association with serum leptin levels and ratio of L/A. Healthy dietary pattern was negatively related to the severity of vessel stenosis. Patients in the third quartile of healthy dietary pattern were less likely to have vessel stenosis (OR = 43%, 95% CI: 0.07-0.87). The findings show that adherence to a healthy dietary pattern was negatively associated with coronary artery stenosis and its related risk factors. However, adherence to western and traditional dietary patterns was positively related to coronary artery disease risk factors.

Effects of a Community-Based Behavioral Intervention with a Traditional Atlantic Diet on Cardiometabolic Risk Markers: A Cluster Randomized Controlled Trial ("The GALIAT Study").

The Atlantic diet, the traditional dietary pattern in northern Portugal and northwest Spain, has been related to metabolic health and low ischemic heart disease mortality. The Galiat Study is a randomized controlled trial aimed to assess the effects of the Atlantic diet on anthropometric variables, metabolic profile, and nutritional habits. The dietary intervention was conducted in 250 families (720 adults and children) and performed at a primary care center. Over six months, families randomized to the intervention group received educational sessions, cooking classes, written supporting material, and foods that form part of the Atlantic diet, whereas those randomized to the control group followed their habitual lifestyle. 213 families (92.4%) completed the trial. Adults in the intervention group lost weight as opposed to controls who gained weight (adjusted mean difference −1.1 kg, p < 0.001) and total serum cholesterol (adjusted mean difference −5.2 mg/dL, p = 0.004). Significant differences in favor of the intervention were found in other anthropometric variables and low-density lipoprotein cholesterol, but changes in triglycerides, high-density lipoprotein cholesterol, inflammation markers, blood pressure, and glucose metabolism were not observed. A family-based nutritional intervention based on the Atlantic diet showed beneficial effects on adiposity and the lipid profile.

The association of dietary patterns with dietary inflammatory index, systemic inflammation, and insulin resistance, in apparently healthy individuals with obesity

Inflammation is considered a key mechanism leading to obesity. Dietary patterns and certain food items influence inflammation. Few studies have investigated the contribution of major dietary patterns to biological measures of inflammation. Therefore, the present study aimed to examine the associations of different dietary patterns with dietary inflammatory index (DII), systemic inflammation, and insulin resistance (IR) in the apparently healthy obese. In this cross-sectional study, 151 abdominally obese subjects were recruited from the Northwest of Iran. Dietary intake, demographic data, anthropometric indices, and physical activity (PA) was assessed. DII scores were calculated based on a validated 168-item food frequency questionnaire (FFQ). Three dietary patterns were identified, using principal component analysis. Basal blood samples were collected to determine biochemical parameters. Linear regression test with adjusted beta estimates was applied for data analysis. Three dietary patterns were extracted as Healthy, Western, and Traditional. Body mass index (BMI) (p < 0.01) and fat mass (p < 0.001) were directly associated with the Western dietary pattern. Conversely, serum lipopolysaccharide-binding protein (LBP) (b = − 0.1, p < 0.04) was negatively associated with Healthy dietary pattern, after controlling for confounders. The Traditional pattern was found to be inversely related to DII (b = − 0.3, p < 0.001). The association was also reveresed between Traditional pattern and IR (Odds Ratio: 0.3 (95% Confidence Interval 0.1–0.9)). The results suggested that the Western dietary pattern was related to higher BMI and fat mass. In addition, the Healthy pattern was associated with decreased levels of LBP. Adherence to the Traditional dietary pattern was inversely related to DII as well as IR.

Dietary patterns and risk of non-alcoholic fatty liver disease

BackgroundNutrition is a modifiable risk factor that plays an important role in the prevention or delaying of the onset of non-alcoholic fatty liver disease (NAFLD). Previous studies have focused on NAFLD and individual nutrients, which does not take into account combinations of food that are consumed. Therefore, we aimed to investigate the relationship between major dietary patterns and NAFLD.MethodsThis case–control study was conducted on 225 newly diagnosed NAFLD patients and 450 healthy controls. Usual dietary intake over the preceding year was assessed using a validated 168-item semi-quantitative food frequency questionnaire. Major dietary patterns were determined by exploratory factor analysis.ResultsThree dietary patterns, including "western dietary pattern", "healthy dietary pattern", and "traditional dietary pattern" were identified. Subjects in the highest tertile of healthy dietary pattern scores had a lower odds ratio for NAFLD than those in the lowest tertile. Compared with those in the lowest tertile, people in the highest tertile of “western dietary pattern” scores had greater odds for NAFLD. After adjusting for potential confounding factors, “western dietary pattern” had a positive significant effect on NAFLD occurrence. In contrast, “healthy dietary pattern” was associated with a decreased risk of NAFLD. Furthermore, Higher consumption of the “traditional dietary pattern” was significantly associated with NAFLD, albeit in the crude model only.ConclusionThis study indicated that healthy and western dietary patterns may be associated with the risk of NAFLD. The results can be used for developing interventions in order to promote healthy eating for the prevention of NAFLD.

Role of plant-based diet in late-life cognitive decline: results from the Salus in Apulia Study

ABSTRACT Objectives Consistency among population-based studies investigating the relationship between diet and cognition in older inhabitants in the Mediterranean area is poor. The present study investigated whether diet changes over 12 years were associated with cognitive function in older people in Southern-Italy. Methods From the ‘Salus in Apulia Study’, that includes the MICOL and GreatAGE Studies, 584 participants were selected, firstly enrolled in MICOL3 (M3) and later in the GreatAGE Study (MICOL4, M4). Foods and micronutrients intake were recorded in both studies, and global cognitive function in M4, assessed with the Mini Mental State Examination. Results Plant-based foods, particularly coffee and vegetables, as well as vitamin A sources, were inversely associated to age-related cognitive impairment. Alcohol consumption showed a detrimental role on cognition, while red meat appeared to be beneficial in the present study, although its role is traditionally considered harmful for cognitive function. Discussion Our study confirmed that a traditional Mediterranean dietary pattern based on agricultural products and low alcohol consumption may help to prevent/delay age-related cognitive impairment.

Association between Dietary Patterns and Major Depression in Adult Females: A Case-Control Study.

Background: Depression is one of the most common mental disorders. This study aimed to determine the association between dietary patterns and major depression in adult females. Study design: A case-control study. Methods: This study was conducted on adult females suffering from major depression within the age range from 19 to 65 years. The total participants of this study included 170 cases and 340 controls. Dietary intakes were collected using a 168-item validated semi-quantitative food-frequency questionnaire. Household food security was measured using a locally adapted Household Food Insecurity Access Scale. Moreover, the depression status of the adult females was assessed through a validated "Beck" questionnaire. Logistic regression was utilized to assess the association between dietary pattern scores and depression. Results: The mean ±SD ages of the participants were 36.97 ±11.28 and 36.07 ±10.58 years in the case and control groups, respectively (P=0.374), and five major dietary patterns were extracted in this study. The odds ratio (OR) in the last adjusted model was (OR: 0.61; 95% CI: 0.46, 0.81); therefore, the "Healthy pattern" was significantly inversely associated with the odds of depression. Adherence to the "Western pattern" significantly increased depression by 29% (OR: 1.29; 95% CI: 1.06, 1.59). Furthermore, the "Traditional pattern" was positively associated with depression (OR: 1.16; 95% CI: 0.94, 1.43). There was no significant association between "Sugar and fast food" and "red meat and oils" dietary pattern and depression. Conclusions: Healthy dietary pattern reduces the risk of depression in adult females; however, the western and traditional dietary patterns increases this risk.

Diet quality and a traditional dietary pattern predict lean mass in Australian women: Longitudinal data from the Geelong Osteoporosis Study.

Low muscle mass is associated with reduced independence and increased risk for falls and fractures. Identification of modifiable risk factors for low muscle mass is thus imperative. This study aimed to examine the longitudinal relationship between both diet quality and patterns and lean mass in Australian women. Data from n=494 participants of the Geelong Osteoporosis Study's 10- and 15-year women's follow-ups were used (conducted in 2004-08 and 2011-14, respectively), and participants were aged 21-89years. Self-reported lifestyle and demographics were collected, and food frequency questionnaire data informed the dietary exposure variables: the Australian Recommended Food Score (ARFS); the Dietary Inflammatory Index (DII); and a posteriori dietary patterns. The outcome, Skeletal Muscle Index (SMI), was calculated from DXA-derived appendicular lean mass (ALM) relative to height (ALM kg/m2). Analyses employed Generalised Estimating Equations. A higher ARFS score positively predicted SMI over 5-years, and adjustments for age and physical activity did not attenuate this relationship (B:0.044, (95%CI 0.004, 0.084)kg/m2). Following adjustment, both an anti-inflammatory diet (B:-0.034, (95%CI -0.070, -0.002) kg/m2) and a 'traditional' dietary pattern predicted higher SMI (B:0.081, (95%CI 0.004, 0.158)kg/m2). No other associations were observed. Our study reinforces the importance of diet quality for healthy, aging muscle mass. Furthermore, a less inflammatory diet and a diet comprising a wide variety of plant and animal foods may be conducive to maintenance of muscle mass in women. Further studies investigating diet quality's impact on various muscle health measures over longer time periods are warranted.

Urinary sodium-to-potassium ratio: a simple and useful indicator of diet quality in population-based studies

BackgroundCurrent evidence regarding the prognostic relevance of urinary sodium-to-potassium ratio (Na-to-K ratio), as an indicator of diet quality is limited. This study was conducted to investigate whether urinary Na-to-K ratio could be related to habitual dietary patterns, in a general population.MethodsThis study was conducted in the framework of the Tehran Lipid and Glucose Study (2014–2017) on 1864 adult men and women. Urinary Na and K concentrations were measured in the morning spot urine samples. Dietary intakes of the participants were assessed using a validated 147-item Food Frequency Questionnaire (FFQ) and major dietary patterns were obtained using principal component analysis. Mediterranean dietary pattern and Dietary Approaches to Stop Hypertension (DASH) score, were also calculated. Multivariable-adjusted linear regression was used to indicate association of dietary patterns and urinary Na-to-K ratio.ResultsMean (± SD) age of participants was 43.7 ± 13.9 years and 47% were men. Mean (± SD) urinary Na, K and the ratio was 139 ± 41.0 and 57.9 ± 18.6 mmol/L, 2.40 ± 0.07, respectively. Higher urinary Na-to-K ratio (> 2.37 vs. < 1.49) was related to lower intakes of vegetables (282 vs. 321 g/day), low-fat dairy (228 vs. 260 g/day) and fruits (440 vs. 370 g/day). Western dietary pattern was related to higher urinary Na-to-K ratio (β = 0.06; 95% CI 0.01, 0.16). Traditional dietary pattern, Mediterranean and DASH diet scores were inversely associated with urinary Na-to-K ratio (β = − 0.14; 95% CI − 0.24, − 0.11, β = − 0.07; 95% CI − 0.09, − 0.01, β = − 0.12; 95% CI − 0.05, − 0.02, respectively).ConclusionsSpot urinary Na-to-K ratio may be used as a simple and inexpensive method to monitor diet quality in population-based epidemiological studies.

Nutrition Transition Between Hunger and Obesity

In the course of global nutritional change, traditional dietary patterns are increasingly being replaced by an urban-industrial dietary style. The proportion of animal-based and, above all, ultra-processed foods is increasing sharply, with dramatic consequences for climate and public health. The epidemics of obesity, malnutrition and climate change are combining to form a ›Global Syndemic‹ that particularly affect low-income countries, where women are especially affected by a double burden of underweight and obesity over their lifetime. The COVID-19 pandemic has further exacerbated the situation and shown how fragile food security is.

East-Greenland traditional nutrition: a reanalysis of the Inuit energy balance and the macronutrient consumption from the Høygaard nutritional data (1936-1937)

ABSTRACT Greenlandic traditional nutrition was unique in the arctic environment because it was an almost exclusive meat dietary pattern. Høygaard et al. left Copenhagen in August 1936, and stayed in East Greenland until August 1937. The four members of the expedition resided in Tasisaq and visited eight settlements around where nutritional intake was recorded by residing in families. However, the nutritional intake was analysed on a household level. The aim of the present study is to reanalyse the Høygaard et al. data according to modern scientific standards. In total, 21 males and 14 females participated. Median (IQR) energy consumption was 3881 (1568) kcal.day−1 for males and 2910 (882) kcal.day−1 for females. Without the five participants living near trading centres, this was 3268 (219) kcal.day−1 and 2634 (723) kcal.day−1, respectively. Expressed in energy-percent, the macronutrient consumptions were 34% for protein, 37% for fat and 29% for carbohydrates. Without imported food, this was 41%, 49% and 10%, respectively. The main findings of the present study are, as expected, that the food consumed came mainly from traditional hunting, was low in plant foods and extremely low in carbohydrates. The Inuit succeeded to stay in apparently healthy conditions with a traditional meat-based dietary pattern.

Vitamin C in East-Greenland traditional nutrition: a reanalysis of the Høygaard nutritional data (1936-1937)

ABSTRACT Greenlandic traditional nutrition was an almost exclusive meat dietary pattern. Høygaard et al. stayed in East-Greenland between August 1936 and August 1937. The four members of the expedition resided in Tasisaq and recorded nutritional intake by residing in families. However, data were analysed on a household level. The aim of the present study is to reanalyse the Høygaard et al. data according to modern scientific standards. In total 21 males and 14 females participated. Median (IQR) vitamin C intake was 79 (77) mg.day−1 for males and 59 (56) mg.day−1 for females. Consumption of meat and organs from seals gave 21 mg.d−1 vitamin C, comparable to vitamin C from algae. Narwhal skin and eyes had a marginal contribution to the vitamin C consumption. The number of adults consuming algae during the research days was 67% for males and 71% for females, this was 24% and 21% for narwhal skin. The main conclusions of the present study are the important role of algae consumption in Greenlandic traditional dietary pattern to avoid scurvy, and that foods traditionally seen as important sources of vitamin C like eyes from seals and narwhal skin, played a minor role in meeting the vitamin C requirements.

Exploration of the Principal Component Analysis (PCA) Approach in Synthesizing the Diet Quality of the Malaysian Population.

(1) Background: One of the most main dietary assessments is through a posteriori application. Although extensive research has incorporated dietary assessment of a population through a posteriori application, this study is the first to examine the Malaysian population and use an a posteriori method and principal component analysis (PCA) to assess the dietary patterns of the Malaysian population. The correlation between all dietary patterns derived via PCA and selected nutrient intake were determined in this sample of study; (2) Methods: A total of 3063 respondents (18 to 59 years old) covering Peninsular Malaysia, Sabah, and Sarawak, participated in this study. PCA was applied on the food frequency questionnaire collected from the respondents, and descriptive statistics and PCA were performed using SPSS version 21; (3) Results: Six patterns were identified: “traditional”, “ prudent”, “ modern”, “western”, “Chinese”, and “combination” diets. All together, these six patterns were able to explain 45.9% of the total variability. Few components derived from the factor loadings showed positive association with several nutrient markers. The traditional dietary pattern showed a moderate, positive correlation with total protein and total sugar intake, there was a significant moderate correlation between the prudent dietary pattern and dietary fibre, and there was a moderate positive association between the Chinese dietary pattern and total energy; and (4) Conclusions: The exploration of the PCA approach above may provide justification for assessment of dietary patterns rather than reliance on single nutrients or foods to identify potential connections to overall nutritional wellbeing as well as to explore the diet–disease relationship. However, study of pattern analysis must be conducted among the Malaysian population to produce validity and reproducibility for this dietary approach in light of the numerous methodological issues that arise when performing PCA.

Combating Malnutrition Among Pregnant Women, Mothers and Babies in the Rural Amazonian Forest: What can Telehealth Do?

Purpose: Malnutrition is a current public health problem and a leading cause of childhood morbidity and mortality among the indigenous population in the Amazon forest. This may be related to the nutritional transition observed among indigenous women in Brazil. This research aims to empower health professionals to promote food and nutritional education for mothers and babies living in the forest of the Brazilian state of Amazonas and its Colombian border. We describe our experience using telehealth to combat malnutrition among pregnant women, mothers and babies in the rural Amazonian forest. Methods: This is a qualitative study that included three interventions: field visits, a scoping review, and online meetings. Data collect from field visits and the scoping review were used to identify demands and incorporate themes discussed in the virtual meetings held at telehealth units. Sessions used the web conferencing platform of the state of Amazonas and were facilitated by Brazilian specialists. Locations were selected according to existence of telehealth site. Results and Conclusions: Seven telehealth sessions were held between April and December in 2018 and three in 2019, including 14 different locations equipped with telehealth points, and lasted 120 minutes each. The main findings were that telehealth services can be an instrument to establish a knowledge exchange between health professionals and indigenous people. The participation of indigenous people in social media could be an instrument to maintain their culture and to promote their healthcare, especially traditional and healthy dietary patterns.

Dietary patterns and trajectories of global- and domain-specific cognitive decline in the Lothian Birth Cohort 1936.

Healthy dietary patterns may protect against age-related cognitive decline, but results of studies have been inconsistent and few have had extensive longitudinal follow-up with comprehensive cognitive testing. The aim of the present study was to determine associations of dietary patterns with trajectories of global- and domain-specific cognitive change over a 12-year period. Data from 863 community-dwelling, dementia-free participants from the Lothian Birth Cohort 1936 study of ageing completed a FFQ at baseline (aged 70 years) and underwent cognitive testing at baseline, and at the ages of 73, 76, 79 and 82 years. Composite cognitive scores were constructed for four cognitive domains (visuospatial ability, processing speed, memory and verbal ability) and global cognitive function. A Mediterranean-style pattern and a traditional pattern were derived using principal component analysis of self-reported dietary intakes. In fully adjusted latent growth curve models, higher baseline adherence to the Mediterranean-style dietary pattern (β = 0·056, P = 0·009) and lower baseline adherence to the traditional dietary pattern (β = -0·087, P < 0·001) were cross-sectionally associated with better verbal ability. A slightly steeper decline in verbal ability over 12 years was observed in those with higher Mediterranean-style diet scores at baseline (β=-0·003, P = 0·008). All other associations were non-significant. Our findings in this well-characterised Scottish cohort indicate that adherence to a healthy Mediterranean-style diet is associated cross-sectionally with better verbal (crystallised) ability, with the converse being true for the traditional diet. A healthier baseline diet did not predict a reduced risk of global- or domain-specific cognitive decline.

Adherence to the Mediterranean Diet in Maltese Adults.

Background: Populations living in Mediterranean islands are experiencing a nutrition transition process from traditional to Westernized dietary patterns. No information on this matter regarding individuals living in Malta have been published to date. The aim of this study was to assess the level of adherence of the Maltese people to the Mediterranean diet and which factors were associated with it. Methods: A nationwide cross-sectional study was conducted in the island of Malta between 2014 and 2016. A literature-based Mediterranean diet adherence score was used to assess the level of adherence to the dietary pattern. Results: Out of 3947 adults, the overall Mediterranean diet adherence score mean was 7.19 (SD 1.91): being female, non-smoker, and having older age was associated with higher adherence to the Mediterranean diet. Less clear pattern of association was found for educational and occupational status, for which medium educational level and a high occupational level were associated with lower adherence to Mediterranean diet. Higher adherence was finally associated with consumption of healthier food groups (more rice and dark bread and less pasta and white bread; more all plant-food groups and fish, less animal-food sources, including fast foods; more light cheeses and yogurt were more frequently consumed among higher adherent individuals in spite of regular ones). Conclusions: Adherence to the Mediterranean diet in Malta is lower than in those of populations living in companion Mediterranean islands. Given the lack of data on this topic, further studies should be conducted among the Maltese people and public health nutrition interventions should be planned to improve current eating habits toward more traditional dietary patterns.

Reduction of traditional food consumption in Brazilian diet: trends and forecasting of bean consumption (2007-2030).

To identify changes in traditional dietary behaviour through the evaluation of trends in bean consumption among adults in Brazil between 2007 and 2017 and to estimate its projections up to 2030. Time-series analysis conducted with data from the Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey (Vigitel) between 2007 and 2017. Weekly consumption of beans was analysed. Prais-Winsten regression evaluated trends for the entire period of study (2007-2017) and in two periods of analyses (2007-2011 and 2012-2017) for the complete set of the population and stratified by socio-demographic characteristics. Estimated prevalence projections were calculated up to the year 2030 using its tendency from 2012 to 2017. Brazil. A probabilistic sample of 572 675 Brazilian adults aged ≥ 18 years. Changes in traditional dietary pattern were identified. Regular consumption of beans (≥ 5 d/week) presented a stable prevalence trend for the total population in the complete and the first analysed period, but a significant decrease in the second half (67·5 % to 59·5 %) among both genders, all age groups and educational levels (except for ≥12 years). The higher magnitude of regular consumption of beans will occur up to the year of 2025 for the total population (46·9 %), when it will be less frequent in the week. Reductions in the weekly consumption of beans may represent the weakness of a traditional food culture in a globalised food system. By 2025, regular consumption of beans will cease to be the predominant habit in the country.

Adherence to Prudent and Mediterranean Dietary Patterns Is Inversely Associated with Lung Cancer in Moderate But Not Heavy Male Polish Smokers: A Case-Control Study.

Lung cancer is the most commonly diagnosed cancer in men worldwide. Studies regarding dietary patterns (DPs) and lung cancer are limited, with results remaining inconclusive, and the association of DPs with lung cancer in smokers is unclear. This study analyzed the associations between DPs, including the Polish-adapted Mediterranean diet (Polish-aMED) score, and lung cancer risk in Polish adult male smokers. This case-control study involved 439 men aged 45–80 years from northeastern Poland, including 187 newly diagnosed lung cancer cases. Dietary data was collected with a 62-item food frequency questionnaire (FFQ-6). Two approaches were applied to identify dietary patterns. The Polish-aMED score was calculated (hypothesis-driven approach) and a principal component analysis (PCA) was used to identify PCA-driven DPs (data-driven approach). A logistic regression analysis was performed to estimate the odds ratio (OR) and 95% confidence interval (95% CI) of the lung cancer risk associated with the adherence to DPs overall as well as for moderate (2.5–11 pack-years) and heavy (>11 pack-years) smokers. Among moderate smokers, the risk of lung cancer was lower by 41% (OR: 0.59; 95% CI: 0.39–0.90; p < 0.05; adjusted model) in the higher adherence to the prudent DP when compared to the lower adherence, and by 66% (OR: 0.34; 95% CI: 0.15–0.76; p < 0.05; adjusted model) in the high adherence (7–9 points) to the Polish-aMED score when compared to the low adherence (0–3 points). No significant association between the westernized traditional DP or the sweet dairy DP and lung cancer was revealed. In conclusion, the current study suggests that pro-healthy dietary patterns, including the Mediterranean pattern, may favour lower risk of lung cancer in moderate smokers, although it was not confirmed in heavy smokers.
