Impact of dietary fats on mental health: Omega-3, saturated, and trans fats in a healthy Israeli population

This study investigates the relationship between dietary fat consumption and mental health in a healthy Israeli population, addressing a gap in research regarding the effects of specific fats—Omega-3, saturated fats, and trans fats—on mental well-being. Despite existing studies on general eating patterns and mental health, limited research focuses on these specific dietary fats within this population. A sample of 98 participants was analysed using a correlational design and measures, including nutrition and psychological self-reported questionnaires. Results revealed that higher consumption of trans fats was significantly associated with increased depressive symptoms, with depressive scores significantly higher in those with a high trans-fat intake (M = 16.67, SD = 5.81) compared to those with lower intake (M = 10.25, SD = 4.95). Additionally, the interaction between trans-fat consumption and PUFA/SFA ratio significantly predicted depressive scores (β = 10.86, p < .001 for high PUFA/SFA ratio; β = 3.77, p < .001 for low PUFA/SFA ratio). Similarly, higher trans-fat consumption was linked to increased anxiety symptoms, as indicated by anxiety scores (β = 12.08, p < .001 for high PUFA/SFA ratio; β = 5.22, p < .05 for low PUFA/SFA ratio). Conversely, consumption of saturated fats did not significantly affect mental health, though interactions with PUFA/SFA ratios were noted (β = .14, p < .05 for high PUFA/SFA ratio). The study highlights the complex relationships between different types of fatty acids and mental health, contributing to a deeper understanding of how specific dietary fats impact mental well-being. These findings suggest potential avenues for nutritional interventions to improve mental health, mainly by reducing trans-fat intake.

Rare variants at KCNJ2 are associated with LDL-cholesterol levels in a cross-population study

Leveraging whole genome sequencing data of 1751 individuals from the UK and 2587 Qatari subjects, we suggest here an association of rare variants mapping to the sour taste-associated gene KCNJ2 with reduced low-density lipoprotein cholesterol (LDL-C, P = 2.10 × 10−12) and with a 22% decreased dietary trans-fat intake. This study identifies a novel candidate rare locus for LDL-C, adding insights into the genetic architecture of a complex trait implicated in cardiovascular disease.

Investigating the complete replacement of conventional fat with oleogel on the structural behavior of five different pastry products

Saturated and trans fat intake have been linked to an increased risk of developing diseases such as cardiovascular and coronary heart disease, obesity, and myocardial infarction. As a result of the actions and regulations proposed to reduce and eliminate the content of saturated and trans fats, it is necessary to develop and implement new structuring technologies, such as oleogelation. Oleogelation is a promising strategy for structuring liquid oil, that allows the incorporation of vegetable oils rich in unsaturated fatty acids into food matrix and which can provide the functionality of solid fats and improved nutritional characteristics. The partial or total replacement of conventional fats with oleogels in pastry products is of great interest due to their larger consumption. In this research paper, the puff (jam-filled puff pastry) and tender pastries (bow tie cookies, cheese crackers, apple pie, and cookies) have been reformulated by totally replacing of conventional fats with oleogel and the structural behavior in the dynamics of the technological process was evaluated. The textural properties of oleogel were comparable to those of some conventional fats, but frequency sweep measurements showed that the oleogel formulated with refined sunflower oil and carnauba wax (10% w/w) had the highest storage modulus G’ and loss modulus G’’ values when compared to conventional fats (commercial margarine, butter, a mixture of 73% margarine and 27% lard, and puff pastry margarine). The textural properties of oleogel (2.34 N and 2.30 mJ) were significantly different from those of puff pastry margarine (9.78 N and 21.73 mJ), but compared to other conventional fats, the values of hardness (1.42–2.70 N) and adhesiveness (4.40–5.17 mJ) were similar. For conventional and oleogel doughs the storage modulus (Gʹ) were higher than loss modulus (G″) and both increased with the applied frequency (Hz). In terms of the products textural profile, the prototypes formed with oleogel exhibited lower hardness values (2.37–15.64 N) than the conventional products (8.83–19.89 N), indicating the tenderizing effect produced by the oleogel. The fat losses determined during 14 days of storage showed a lower physical stability of the doughs and products formulated with oleogel, most probably due to the destabilization kinetics of the lipid system during the operations of the technological process.

Hronične nezarazne bolesti uzrokovane poremećajima ishrane kod adolescenata

Decreased satisfaction with physical appearance during adolescence is significantly linked to reduced self-esteem and an increased prevalence of obesity and other chronic non-communicable diseases (NCDs). A major issue in today's world is the influence of media, which serves as the primary channel through which ideals of physical appearance and attractiveness are transmitted. According to a 2015 study, adolescents spend an average of 17 hours per week watching television. Scientific evidence indicates that an active lifestyle provides health benefits and prevents the occurrence of numerous chronic non-communicable diseases, while improper diet and physical inactivity among adolescents contribute to the development of these diseases. Improper nutrition during adolescence can be a significant risk factor for the development of NCDs. These diseases, including cardiovascular diseases, diabetes, and certain forms of cancer, often have complex causes, but dietary habits can be identified as a common risk factor. Excessive intake of saturated and trans fats, cholesterol, and a high consumption of processed foods are associated with an increased risk of cardiovascular diseases. Improper dietary habits can also contribute to the development of type 2 diabetes and increase cancer risk. Adopting a balanced and nutritionally rich diet, along with regular physical activity, can help prevent and manage these conditions. This review paper is based on a search of the scientific literature published in the last ten years, with a special focus on original research articles published in the last five years from the scientific databases: PubMed, SCOPUS, MEDLINE, and SCI index.

Higher diet quality relates to better cardiac function in cancer survivors: The multi-ethnic study of atherosclerosis

BackgroundCancer therapies induce cardiac injury and increase cardiovascular disease (CVD) risk. In non-cancer populations, higher diet quality is associated with protection against CVD, but the relationship between diet and cardiac function in cancer survivors is unknown. MethodsThis cross-sectional analysis from the Multi-Ethnic Study of Atherosclerosis (MESA) cohort included 113 cancer survivors (55 breast, 53 prostate, three lung, and three blood) and 4233 non-cancer controls. Dietary intake was reported via validated food frequency questionnaire. Alternate healthy eating index (AHEI) was calculated as a measure of quality. Cardiac function, determined as left ventricular ejection fraction (LVEF), was assessed by cardiac magnetic resonance. ResultsCancer survivors had a lower LVEF compared to controls (61.3 ± 6.5% v 62.4 ± 6.1%, p = 0.04). In all participants, total fat (β ± SE: −0.04 ± 0.01, p = 0.004), saturated fat (−0.11 ± 0.03, p < 0.001), and trans-fat (−0.36 ± 0.12, p = 0.002) intake were inversely associated with LVEF while AHEI (0.03 ± 0.01, p < 0.001) was positively associated with LVEF. Among cancer survivors only, sucrose intake was negatively related to LVEF (−0.15 ± 0.06, p = 0.02), and the ratio of unsaturated fat to saturated fat (2.7 ± 1.1, p = 0.01) and fiber intake (0.42 ± 0.14, p = 0.003) were positively related to LVEF. DiscussionIn cancer survivors, improved dietary fat and carbohydrate quality (i.e., greater consumption of unsaturated fatty acids and fiber) was associated with favorable cardiac function, while higher sucrose was associated with worse cardiac function. Further research is needed to confirm these findings and test whether changes in the identified dietary factors will modulate cardiac function in cancer survivors.

Self-reported engagement in healthy eating behaviors is associated with favorable dietary intake among adults in Puerto Rico

A diet high in quality is essential for prevention of chronic diseases. Specific healthy eating behaviors may modulate dietary intake. However, these behaviors have been seldomly studied, particularly in Puerto Rico (PR), a population with documented poor dietary quality and high burden of chronic diseases. This study aimed to document self-reported engagement in eating behaviors and examine their associations with intake of nutrients and diet quality. We hypothesized that greater engagement in healthy eating behavior would be associated with greater diet quality. This cross-sectional analysis used data from the PRADLAD study (adults aged 30-75 years residing in the San Juan, PR, area [n = 234]). Frequency (never, sometimes, often, always) of habitual eating behaviors was measured. Dietary intake was assessed with a food frequency questionnaire. Diet quality was measured with the Alternate Healthy Eating Index-2010. Statistical analyses included adjusted linear models. The most common behavior was “controlling intake of salt” (51.7%). Engaging “always” (vs. less frequently) in making healthier meals, reading nutrition facts labels, searching media for healthy eating information, counting calories, buying organic foods, eating a vegetarian diet, and controlling intake of salt, fat, carbohydrates/sugar, and portions were associated with higher Alternate Healthy Eating Index-2010 scores (P < .05). Controlling intakes of fats, carbohydrates/sugars, and portions “always” was associated with lower intakes of trans fats, added sugars, and total food (g), respectively (P < .05). Engagement in eating a vegetarian diet “always” was associated with higher intake of plant-based protein (P < .05). In conclusion, adults following several habitual eating behaviors had greater diet quality and a lower amount of unfavorable nutrients. Encouraging adherence to these behaviors may contribute to healthier dietary intake.

Associations of Dietary Intake With Self-Reported Hearing Loss: Findings From the Survey of the Health of Wisconsin.

The purpose of this study was to evaluate associations of dietary intake components with hearing loss. Participants were from the population-based Survey of the Health of Wisconsin. The Block food frequency questionnaire measured dietary intake of carbohydrates, fiber, protein, free (added) sugars, fruits, vegetables, saturated and trans fats, and glycemic index. Intake was categorized into quintiles (Q). Hearing loss was self-reported. Logistic regression models were used to evaluate associations of dietary determinants with hearing loss. Results are presented as odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs). Final models were adjusted for age, sex, total energy intake, race/ethnicity, education, smoking, and regular physical activity. There were 2,839 participants (56% women; Mage = 48.2 [SD = 14.5] years) included. Higher consumption of trans fat (Q5: OR = 1.83, 95% CI [1.27, 2.64]) and higher glycemic index (Q5: OR = 1.34, 95% CI [1.00, 1.80]) were associated with increased odds of hearing loss. Hearing loss was associated with fruit, saturated- and trans-fat intake in women, and trans-fat intake and glycemic index in men. Dietary intake was associated with self-reported hearing loss. Research on mechanistic pathways of associations and public health interventions to prevent hearing loss is needed.

Relationship Between Sleep and Hypertension: A Narrative Review

The risk of cardiovascular disease increases at an alarming rate with the increase in an individual’s blood pressure. Rise in systemic arterial blood pressure can be caused by factors such as unhealthy diet (excessive intake of salts, trans-fats and saturated fats), alcohol intake, inadequate sleep, smoking and decreased levels of physical activity. This narrative review aims at providing an overview of the existing studies on the relationship between duration of sleep as well as its quality and hypertension. The studies reported in this review were collected from the databases that include PubMed, Sciencedirect, Hindawi, ResearchGate and AHA journals in the period of 2006-2022. The keywords used for searching in the databases included sleep, insomnia, hypertension and cardiovascular diseases. The two sociodemographic variables considered was age and gender. Literature review showed that individuals reporting shorter durations of sleep, disrupted sleep patterns and insomnia were shown to be suffering from hypertension as compared to individuals receiving adequate and quality sleep at night. Data from this review article can prove beneficial to the common population in the understanding of sleep being a modifiable risk factor of hypertension and encourage healthcare workers and patients to make the necessary changes in their sleeping patterns to prevent hypertension and associated cardiovascular events.

The Influence of Dietary Interventions on Arterial Stiffness in Overweight and Obese Subjects.

Arterial stiffness is often increased in overweight/obese subjects before the development of hypertension. It is also one of the earliest indicators of increased cardiovascular disease risk and can be considered a good predictor of the development of subclinical cardiovascular dysfunction. Arterial stiffness is a significant prognostic factor influencing cardiovascular risk, which dietary habits can modify. Obese patients should use the caloric-restricted diet because it augments aortic distensibility, diminishes pulse wave velocity (PWV), and increases the activity of endothelial nitric oxide synthases. High intake of saturated fatty acids (SFA), trans fats, and cholesterol, typical for the Western diet, impairs endothelial function and raises brachial-ankle PWV. The replacement of SFA with monounsaturated (MUFA) or polyunsaturated fatty acids (PUFA) derived from seafood and plants diminishes the risk of arterial stiffness. The dairy product intake (excluding butter) decreases PWV in the general population. The high-sucrose diet causes toxic hyperglycemia and increases arterial stiffness. Complex carbohydrates with a low glycemic index (including isomaltose) should be recommended to keep vascular health. The high sodium intake (>10 g/day), particularly associated with low potassium consumption, has a deleterious effect on arterial stiffness (↑ baPWV). Since vegetables and fruits are good sources of vitamins and phytochemicals, they should be recommended in patients with high PWV. Thus, the dietary recommendation to prevent arterial stiffness should be similar to the Mediterranean diet, which is rich in dairy products, plant oils, and fish, with a minimal red meat intake and five servings of fruits and vegetables daily.

Plasma brain derived neurotrophic factor level as a modifying factor for trans fat intake and hypertension

Long-term consumption of trans-fat has been linked with its incorporation in brain neural membrane that could lead into alteration of signalling pathways, including Brain Derived Neurotrophic Factor (BDNF). As an ubiquitous neurotrophin, BDNF is believed to play a role in the regulation of blood pressure yet prior studies shown conflicting results to its effect. Moreover, direct effect of trans fat intake to hypertension has not yet been elucidated. This study aimed to investigate the role of BDNF and its association between trans-fat intake and hypertension. We conducted a population study in Natuna Regency which once reportedly has the highest prevalence of hypertension from Indonesian National Health Survey. Subjects with hypertension and those without hypertension were recruited for the study. Demographic data, physical examination, and food recall were collected. The level of BDNF from all subjects were obtained through analysis of blood samples. A total of 181 participants were included in this study, comprising 134 (74%) hypertensive subjects and 47 (26%) normotensive subjects. Median of daily trans-fat intake of hypertensive subjects was higher compared to normotensive subjects (0,013 [0,0003-0,07] vs 0,010 [0,0006-0,06] % of total energy/day, p=0,021). Interaction analysis showed significant results for plasma BDNF level in relationship of trans-fat intake and hypertension (p=0,011). Trans-fat intake association to hypertension in overall subjects showed odds ratio (OR) of 1,85 95%CI 1,05-3,26 (p=0,034), while in those with low-middle tercile BDNF level the OR was 3,35 95%CI 1,46-7,68 (p=0,004). Plasma BDNF level has a modifying effect in the association between trans-fat intake and hypertension. Subjects with high trans-fat intake, while having low BDNF level, have the highest probability for hypertension.

A high Diabetes Risk Reduction Score (DRRS) is associated with a better cardio-metabolic profile among obese individuals

BackgroundDietary indices and scores are valuable predictive markers against chronic diseases. Several previous studies have revealed the beneficial effects of diabetes risk reduction score (DRRS) against diabetes and cancer incidence. However, its association with metabolic abnormalities among obese individuals have not been revealed before. In the current study, we aimed to investigate the association between DRRS and metabolic risk factors among obese individuals.MethodsIn the current cross-sectional study, 342 obese individuals [Body mass index (BMI) ≥ 30 kg/m2] aged 20–50 years were included. Dietary intake was assessed by a validated semi-quantitative food frequency questionnaire (FFQ) of 168 food items and DRRS was calculated. Metabolic syndrome (MetS) was defined based on the guidelines of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III). Enzymatic methods were used to assess serum lipids, glucose, and insulin concentrations. Blood pressure was measured by a sphygmomanometer and body composition with bioelectrical impedance analysis (BIA).ResultsThose with a higher adherence to DRRS had a significantly higher intake of energy, fiber, and lower protein compared with those in the lower quartiles. Moreover, lower intakes of trans fats, meat, sugar sweetened beverages (SSB), and glycemic index (GI) with higher intakes of fruits, cereal fiber, polyunsaturated fatty acids/ saturated fatty acids (PUFA/ SFA) ratio, coffee, and nuts were observed in the highest versus lowest DRRS categories. Lower systolic blood pressure, diastolic blood pressure, triglyceride and, higher high-density lipoprotein values were observed in higher DRRS categories. Logistic regression analysis showed that hypertension was significantly associated with adherence to DRRS among obese individuals, the odds ratio (OR) was 0.686 (95% confidence interval [CI], 0.26–0.84) after adjustment for potential confounders. But the risk of other components of MetS was not significantly associated with higher quartiles of adherence to DRRS. Also, a non-significantly lower prevalence of MetS was observed in the higher quartile of DRRS.ConclusionsAccording to the results of the current study, higher DRRS was associated with lower blood pressure, modified serum lipids, and lower Mets prevalence. Further studies in different populations are warranted for better generalization of the obtained findings.

Diet and Gestational Diabetes Mellitus: A Systematic Review Study

Objective: Diet may have an impact on gestational diabetes mellitus (GDM) development; nevertheless, controvertible studies have been published. The aim of this study was to provide evidence from analytical studies on the relationship between diet and GDM development. Methods: Following the PRISMA guidelines, ISI Web of Knowledge, PubMed, Google Scholar, Scopus, Embase, and the Cochrane library were searched for articles published in the English language from Jan 2005 to Dec 2020. We included observational studies, assessed their risk of bias, and extracted data on association between diet status and GDM development. Keywords were selected based on the Mesh terms, which included gestational diabetes mellitus“, “GDM”, “diet,” “nutrition,” “food,” “dietary pattern which was combined by "OR" and "AND" Boolean operators. Two reviewers (SHA and PM) independently reviewed abstracts and full-text articles and extracted data. Results: Among the 5 articles included, 4 were case-control and one was a cross-sectional study. Studies have shown that diets with a high intake of saturated fatty acids (more than 10% of total daily fat intake) and trans fatty acids (more than 1% of total daily fat intake) before and during pregnancy significantly increase the risk of gestational diabetes mellitus. Conclusion: High intake of saturated fat and trans fat before and during pregnancy can disturb glucose metabolism and increase the risk of GDM, although all of the studies recommend more widespread observational and clinical trials studies to identify the exact relationship between high saturated and trans fatty acids intake and GDM.

Impact of Ultra-Processed Food Consumption on Quality of Diet among Brazilian Pregnant Women Assisted in Primary Health Care.

The quality of diet and nutritional status during pregnancy are crucial to optimize maternal and fetal health. Ultra-processed foods (UPFs) are increasingly prevalent in pregnancy groups despite being nutritionally unbalanced and associated with adverse perinatal outcomes. This cross-sectional study, conducted with data from 229 pregnant women, aimed to investigate the association between UPFs consumption and dietary nutrient intake of pregnant women assisted by Primary Health Care (PHC) in Federal District (DF), Brazil. Food consumption was assessed through two non-consecutive 24-h food records and categorized by the extent of processing using the NOVA classification. Multivariate linear regression models were used to analyze the association between the quintiles of UPF consumption and the total energy and nutrients intake. Mean daily energy intake was 1741 kcal, with 22.6% derived from UPFs. Greater UPF consumption was associated with reduced intake of unprocessed and minimally processed food. The highest quintile of UPFs was positively associated with higher total energy, trans fat, and sodium intake; and inversely associated with the diet content of protein, fiber, iron, magnesium, potassium, copper, zinc, selenium, and folate. Greater UPFs intake negatively impacts the nutritional quality of the diet and impoverishes the nutrient intake of pregnant women. Reducing UPF consumption may broadly improve dietary guidelines adherence in pregnant women and promote maternal and neonatal health.

Ultra-processed foods and the nutritional quality of the diet of Brazilian pregnant women

The aim of this study was to evaluate the consumption of ultra-processed foods by Brazilian pregnant women and its association with the nutritional quality of the diet. This is a prospective and cross-sectional study with food consumption data of Brazilian pregnant women from the 2017 to 2018 Family Budgets Survey (Pesquisa de Orçamentos Familiares). Food consumption was measured using two 24-h food recalls, and the foods were categorized according to the NOVA classification. The averages of absolute and relative energy consumption for each of the NOVA groups and subgroups were estimated. The sociodemographic characteristics described the diet's caloric contribution of ultra-processed and non-ultra-processed food fractions. Linear regression models were used to describe the association between quintiles of the caloric contribution of ultra-processed foods and the average content of nutrients in the diet. Consumption of ultra-processed foods represented 20.9% of the total calories in the diet of Brazilian pregnant women. There was a higher energy contribution of ultra-processed foods in the diet of pregnant women living in urban areas (22%), with higher per capita income (23.7%), and in the south region of the country (26.9%). In addition, the data showed an association between higher consumption of ultra-processed foods with reduced intake of protein, carbohydrate, fiber, potassium, iron, zinc, and folate and increased intake of total fat, saturated fat, trans fat, and free sugar. Results show that higher consumption of ultra-processed foods is associated with a reduction in the nutritional quality of the diet of Brazilian pregnant women.

RSSDI Guidelines for the management of hypertension in patients with diabetes mellitus.

Hypertension and diabetes mellitus (DM) are two of the leading lifestyle diseases in the Indian and South Asian populations that often co-exist due to overlapping pathophysiological factors. Obesity, insulin resistance, inflammation, and oxidative stress are thought to be some common pathways. Up to 50% of hypertensive cases in India are diagnosed with type 2 diabetes mellitus (T2DM), which defines the need for a comprehensive guideline for managing hypertension in diabetic patients. These RSSDI guidelines have been formulated based on consultation with expert endocrinologists in India and Southeast Asia, acknowledging the needs of the Indian population. Ambulatory blood pressure monitoring and office and home-based blood pressure (BP) monitoring are recommended for the early analysis of risks. Cardiovascular risks, end-organ damage, and renal disorders are the primary complications associated with diabetic hypertension that needs to be managed with the help of non-pharmacological and pharmacological interventions. The non-pharmacological interventions include the nutrition education of the patient to reduce the intake of salt, sodium, and trans fats and increase the consumption of nuts, fresh fruits, vegetables, and potassium-rich foods. It is also recommended to initiate 50 to 60min of exercise three to four times a week since physical activity has shown to be more beneficial for hypertension control in Indian patients than dietary modulation. For the pharmacological management of hypertension in patients with T2DM, angiotensin II receptor blockers (ARBs) are recommended as the first line of therapy, demonstrating their superiority over other antihypertensive agents such as ACEi. However, most of the global hypertension guidelines recommend initiation with combination therapy to achieve better BP control in most patients and to reduce the risk of adverse events. For combination therapy, calcium channel blockers (CCBs) are recommended to be administered along with ARBs instead of beta-blockers or diuretics to avoid the risk of cardiovascular events and hyperglycaemia. Among the CCBs, novel molecules (e.g. cilnidipine) are recommended in combination with ARBs for better cardiovascular and reno-protection in diabetic hypertensive patients.

Machine learning integration of multimodal data identifies key features of blood pressure regulation.

SummaryBackgroundAssociation studies have identified several biomarkers for blood pressure and hypertension, but a thorough understanding of their mutual dependencies is lacking. By integrating two different high-throughput datasets, biochemical and dietary data, we aim to understand the multifactorial contributors of blood pressure (BP).MethodsWe included 4,863 participants from TwinsUK with concurrent BP, metabolomics, genomics, biochemical measures, and dietary data. We used 5-fold cross-validation with the machine learning XGBoost algorithm to identify features of importance in context of one another in TwinsUK (80% training, 20% test). The features tested in TwinsUK were then probed using the same algorithm in an independent dataset of 2,807 individuals from the Qatari Biobank (QBB).FindingsOur model explained 39·2% [4·5%, MAE:11·32 mmHg (95%CI, +/- 0·65)] of the variance in systolic BP (SBP) in TwinsUK. Of the top 50 features, the most influential non-demographic variables were dihomo-linolenate, cis-4-decenoyl carnitine, lactate, chloride, urate, and creatinine along with dietary intakes of total, trans and saturated fat. We also highlight the incremental value of each included dimension. Furthermore, we replicated our model in the QBB [SBP variance explained = 45·2% (13·39%)] cohort and 30 of the top 50 features overlapped between cohorts.InterpretationWe show that an integrated analysis of omics, biochemical and dietary data improves our understanding of their in-between relationships and expands the range of potential biomarkers for blood pressure. Our results point to potentially key biological pathways to be prioritised for mechanistic studies.FundingChronic Disease Research Foundation, Medical Research Council, Wellcome Trust, Qatar Foundation.

Macronutrients Not Micronutrients Are Associated With the Risk of Pancreatic Cancer

Pancreatic cancer (PC) has been related directly to many risk factors; however, diet is considered one of the most modifiable risk factors. This study is designed to observe the associations between the intake of macromicronutrients and the risk of pancreatic cancer in a Jordanian population. A case-control study included 100 patients with the incident and histologically confirmed PC and 309 control subjects frequency-matched on age, educational level, occupation, and marital status. Face-to-face interview was used to collect the study's sociodemographic, physical activity, and dietary information. Intakes of macronutrients and micronutrients were assessed by a validated food-frequency questionnaire. Multinomial logistic regression was used to calculate odds ratios and confidence intervals. The patients reported higher consumption of almost all the macromicronutrients and micronutrients as compared with control subjects. The highest tertile of dietary intake of carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, cholesterol, and vitamin B3 was positively associated with PC risk (Ptrend < 0.05). However, dietary intakes of polyunsaturated fats, omega-3, and some vitamins and minerals were not associated (Ptrend > 0.05) with the risk of PC. Our findings support the positive role of proteins, carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, and cholesterol on pancreatic carcinogenesis.

Association between APOE Genotype with Body Composition and Cardiovascular Disease Risk Markers Is Modulated by BMI in Healthy Adults: Findings from the BODYCON Study.

Body mass index (BMI) has been suggested to play an important role in the relationship between the APOLIPOPROTEIN (APO)E genotype and cardiovascular disease (CVD) risk. Using data from the BODYCON cross-sectional study (n = 360 adults) we assessed the association between body composition and CVD risk markers according to APOE genotype, with examination of the role of BMI. In this study cohort, the APOE2/E3 group had lower fasting blood lipids than APOE4 carriers and APOE3/E3 group (p ≤ 0.01). After stratifying the group according to BMI, APOE4 carriers in the normal BMI subgroup had a higher lean mass compared with the APOE3/E3 group (p = 0.02) whereas in the overweight/obese subgroup, the android to gynoid percentage fat ratio was lower in APOE4 carriers than APOE3/E3 group (p = 0.04). Fasting lipid concentrations were only different between the APOE2/E3 and other genotype groups within the normal weight BMI subgroup (p ≤ 0.04). This finding was associated with a lower dietary fibre and a higher trans-fat intake compared with APOE4 carriers, and a lower carbohydrate intake relative to the APOE3/E3 group. Our results confirm previous reports that BMI modulates the effect of APOE on CVD risk markers and suggest novel interactions on body composition, with diet a potential modulator of this relationship.

Effects of Single Nucleotide Polymorphisms and Mediterranean Diet in Overweight or Obese Postmenopausal Women With Breast Cancer Receiving Adjuvant Hormone Therapy: A Pilot Randomized Controlled Trial.

Background and AimsWeight management is recommended in overweight or obese breast cancer patients, as they have an increased risk of cancer recurrence and poor prognosis. Furthermore, identifying the relationships between genetic factors and nutrition could help suggest possible individualized nutritional solutions in weight management. The objective of this pilot randomized controlled trial was to investigate the influence of two obesity-associated single nucleotide polymorphisms and the Mediterranean diet intervention on weight loss and modification of nutrient intake and metabolic parameters in overweight or obese, postmenopausal, breast cancer patients receiving adjuvant hormone therapy.MethodsSeventy-eight breast cancer patients were randomly assigned to the Mediterranean diet (MeDiet) group or control group, and seventy-one were finally analyzed. Body composition, nutrient intake, and metabolic parameters were assessed at baseline and after the 8-week intervention. Fat mass and obesity-associated (FTO) rs7185735 and melanocortin-4 receptor (MC4R) rs476828 variants were genotyped.ResultsWe found that both variants did not influence weight loss or improvement of metabolic parameters within the Mediterranean diet intervention. Intake of saturated fatty acid (SFA) and trans fat was significantly increased in C carriers compared with the TT genotype of MC4R rs476828 only in the control group (p = 0.002 for SFA; p = 0.016 for trans fat), whereas no significant difference was observed between genotypes in the MeDiet group. There were statistically significant interactions between MC4R rs476828 and dietary intervention for changes in SFA intake (p = 0.009) and trans fat intake (p = 0.049).ConclusionOur data suggest that considering the effects of genotype may be more necessary when the Mediterranean diet is not followed and that this diet may have a protective role against the effects of certain genotypes. Further studies are required to determine the potential mechanism of the observed gene-diet interaction.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT04045392].
