RESUMEN

Few studies have examined the role of maternal diet in relation to development of coeliac disease (CD). In Denmark, cancellation of mandatory vitamin D fortification of margarine in June 1985 provided this opportunity. This study examined if season of birth or prenatal exposure to extra vitamin D from food fortification were associated with developing CD later in life. A strength of this study is the distinctly longer follow-up of patients (30 years). This register-based study has a semi-ecological design. Logistic regression analysis was used to estimate odds ratios and to calculate 95% confidence intervals. The odds ratio for developing CD was 0.81 (95% CI 0.66; 1.00 p = 0.054), comparing those with fetal exposure to mandatory vitamin D fortification policy of margarine to those without after adjusting for gender and season of birth. There was a statistically significant season effect particularly for children born in autumn (OR 1.6 95% CI 1.16; 2.21) and born in summer (OR 1.5 95% CI 1.1; 2.1) when compared to children born in winter. Although this study did not find evidence to support the premise that prenatal exposure to small extra amounts of vitamin D from a mandatory food fortification policy lowered risk of developing CD, the small number of CD cases and observed association between season of birth and CD suggest that environmental exposure ought to be further explored.

RESUMEN

The decreasing of content of animal, palmitic milk fat (butter) by means of its substitution with vegetable, oleic, palmy oil in food of adults optimal by its quantity is physically chemically and biologically substantiated. In oleic palmy oil higher content of oleic mono unsaturated fatty acid and oleic triglycerides than in creamy fat is established. The biologic availability of palmitic unsaturated palmitic acid in the form of free fatty acid is decreased at its absorption by enterocytes of small intestines is detected. There are no transforms of mono unsaturated acids in palmy oil in contrast with hydrogenated margarines. In palmy, oleic oil there is not enough of short-chained fatty acids (C4-C6) and it has no taste quality and it has low level of unsaturated fatty acids and factually it is lacking of ω-6 polyunsaturated fatty acids. However, it is compensated in case of availability offish and sea products in food. If adults, especially older ones, will refuse to consume creamy fat and decrease intake of products with high content of palmitic unsaturated fatty acid and palmitic triglycerides (beef, sour cream, fatty cheeses) it'll positively impact their health. The refusal from these products is a real step in prevention of metabolic pandemic (atherosclerosis and atheromatosis, metabolic syndrome, resistance to insulin, obesity). There are still large number of people who at optimal amount of food retain in vivo increased amount of exogenous, endogenously synthesized from glucose palmitic unsaturated fatty acid in the form of unesterified fatty acids (syndrome of resistance to insulin) and increased content of palmitic triglycerides.

RESUMEN

BACKGROUND: Children growing up on small family farms are at much lower risk of developing allergy than other children. We hypothesized that low intake of margarine and polyunsaturated fats among farming families could contribute to this protection. METHODS: Twenty-eight mother-infant pairs living on small dairy farms and 37 nonfarm rural resident pairs were recruited in the FARMFLORA birth cohort. Food items expected to affect dietary fat composition were recorded by food frequency questionnaires during pregnancy and by 24-h recalls followed by 24-h food diaries during lactation. Allergy was diagnosed by doctors, using strict predefined criteria. Maternal diet and breast milk fat composition were compared between farming and nonfarming mothers and related to children's allergy at age 3 y. RESULTS: Farming mothers consumed more butter, whole milk, saturated fat, and total fat than nonfarming mothers, who consumed more margarine, oils, and low-fat milk. Farming mothers' breast milk contained higher proportions of saturated and lower proportions of polyunsaturated fat. Allergy was eight times more common in nonfarm children. Mothers of allergic children consumed more margarine and oils than mothers of nonallergic children. CONCLUSION: Low maternal consumption of margarine and vegetable oils might contribute to the allergy-preventive effect of growing up on small dairy farms.

RESUMEN

BACKGROUND: Olive oil has been shown to improve various cardiometabolic risk factors. However, to our knowledge, the association between olive oil intake and type 2 diabetes (T2D) has never been evaluated in the US population. OBJECTIVE: We aimed to examine the association between olive oil intake and incident T2D. DESIGN: We followed 59,930 women aged 37-65 y from the Nurses' Health Study (NHS) and 85,157 women aged 26-45 y from the NHS II who were free of diabetes, cardiovascular disease, and cancer at baseline. Diet was assessed by validated food-frequency questionnaires, and data were updated every 4 y. Incident cases of T2D were identified through self-report and confirmed by supplementary questionnaires. RESULTS: After 22 y of follow-up, we documented 5738 and 3914 incident cases of T2D in the NHS and NHS II, respectively. With the use of Cox regression models with repeated measurements of diet and multivariate adjustment for major lifestyle and dietary factors, the pooled HR (95% CI) of T2D in those who consumed >1 tablespoon (>8 g) of total olive oil per day compared with those who never consumed olive oil was 0.90 (0.82, 0.99). The corresponding HRs (95% CIs) were 0.95 (0.87, 1.04) for salad dressing olive oil and 0.85 (0.74, 0.98) for olive oil added to food or bread. We estimated that substituting olive oil (8 g/d) for stick margarine, butter, or mayonnaise was associated with 5%, 8%, and 15% lower risk of T2D, respectively, in the pooled analysis of both cohorts. CONCLUSIONS: Our results suggest that higher olive oil intake is associated with modestly lower risk of T2D in women and that hypothetically substituting other types of fats and salad dressings (stick margarine, butter, and mayonnaise) with olive oil is inversely associated with T2D.

RESUMEN

To assess whether the type of fat ingested at breakfast can modify the plasma lipid profile and other cardiovascular risk variables in postmenopausal women at risk of cardiovascular disease, a longitudinal, randomized, and crossover study was carried out with postmenopausal women at risk of CVD. They were randomly assigned to eat each type of breakfast during one month: 6 study periods (breakfast with the same composition plus butter/margarine/virgin olive oil) separated by two washout periods. On the first and last days of each study period, weight, arterial blood pressure, heart rate, and body mass index were recorded in fasting conditions and a blood sample was collected to measure plasma lipid profile. When comparing final values to baseline values, we only found out statistically significant differences on plasma lipid profiles. Butter-based breakfast increased total cholesterol and HDL, while margarine-based breakfast decreased total cholesterol and LDL and increased HDL. After the olive oil-based breakfast intake, a tendency towards a decrease of total cholesterol and LDL levels and an increase of HDL levels was observed. No statistically significant differences were observed in triglycerides levels, BMI, and arterial pressure in any breakfast type. The margarine-based breakfast was the only one which significantly increased the percentage of volunteers with optimal lipid profiles. The polyunsaturated fat at breakfast has improved the plasma lipid profile in the analyzed sample population, suggesting that PUFA-based breakfast can be advisable in women at risk of CVD.

RESUMEN

BACKGROUND AND PURPOSE: Binge eating disorder (BED) is characterized by excessive food intake during short periods of time. Recent evidence suggests that alterations in the endocannabinoid signalling could be involved in the pathophysiology of BED. In this study, we investigated whether pharmacological manipulation of endocannabinoid transmission may be effective in modulating the aberrant eating behaviour present in a validated rat model of BED. EXPERIMENTAL APPROACH: Binge-type eating was induced in female rats by providing limited access to an optional source of dietary fat (margarine). Rats were divided into three groups, all with ad libitum access to chow and water: control (C), with no access to margarine; low restriction (LR), with 2 h margarine access 7 days a week; high restriction (HR), with 2 h margarine access 3 days a week. KEY RESULTS: Compared with the LR group, the HR group consumed more margarine and this was accompanied by an increase in body weight. The cannabinoid CB1/CB2 receptor agonist Δ9-tetrahydrocannabinol significantly increased margarine intake selectively in LR rats, while the fatty acid amide hydrolase inhibitor URB597 showed no effect. The CB1 receptor inverse agonist/antagonist rimonabant dose-dependently reduced margarine intake in HR rats. Notably, in HR rats, chronic treatment with a low dose of rimonabant induced a selective long-lasting reduction in margarine intake that did not develop tolerance, and a significant and persistent reduction in body weight. CONCLUSIONS AND IMPLICATIONS: Chronic pharmacological blockade of CB1 receptors reduces binge eating behaviour in female rats and may prove effective in treating BED, with an associated significant reduction in body weight.

RESUMEN

AIM: To explore the association between maternal dietary fat and fatty acid (FA) intake during lactation, and the risk of asthma in the offspring by the age of 5 years. METHODS: The subjects comprised 1798 mother-child pairs from the Type 1 Diabetes Prediction and Prevention (DIPP) Nutrition Study. Dietary intake was assessed by a validated 181-item food frequency questionnaire, which covered the third month of lactation. The cumulative incidence of asthma was assessed at the age of 5 years with a questionnaire modified from the International Study of Asthma and Allergies in Childhood (ISAAC). Cox proportional hazards regression was used for statistical analysis. RESULTS: The maternal use of margarines during lactation was associated with a marginally increased risk of asthma [hazard ratio (HR) for user vs. nonuser 1.96, 95% confidence interval (CI) 1.01-3.82, p = 0.047] after adjusting for putative confounders. The maternal intakes of n-3 polyunsaturated FA (PUFA) and fish during lactation were not associated with the risk of asthma. CONCLUSION: Maternal use of margarines during lactation was weakly associated with an increased risk of asthma in the offspring at the age of 5 years. Other fats or FAs during lactation were not associated with the risk of asthma. However, the nonadherence to dietary recommendations regarding especially fats of our study population may restrict the generalizability of our results.

RESUMEN

OBJECTIVES: The objective of this study was to evaluate functional effects of margarine supplemented with individual CLA isomers trans-10, cis-12 and cis-9, trans-11 in apoE/LDLR -/- mice. DESIGN: In LONG experiment (LONG), two-month old mice with no atherosclerosis were assigned to experimental groups and fed for the next 4 months. In SHORT experiment (SHORT), four-month old mice, with pre-established atherosclerosis, were assigned to experimental groups and fed for the next 2 months. The experimental diets were: AIN-93G (margarine), AIN-93G + 0.5% trans-10, cis-12 CLA (t10c12), and AIN-93G + 0.5% cis-9, trans-11 CLA (c9t11). RESULTS: In both experiments (LONG and SHORT), liver weight was significantly (P<0.05) increased in mice fed t10c12 CLA. Hepatic steatosis was found in animals fed t10c12 diet and no signs of the steatosis was observed in mice fed c9t11 CLA. Dietary treatments with t10c12 CLA significantly increased total plasma cholesterol and plasma triacylglycerols. There were no isomer-specific effects of CLA isomers on area of atherosclerotic plaque in aortic root. CONCLUSION: In conclusion, t10c12 CLA significantly increased liver weight in mice in LONG and SHORT experiments. Our results do not support the notion that CLA isomer supplementation to the margarine possess anti-atheroclerotic effect. Therefore, no isomer-specific effects of CLA on development of atherosclerosis were observed.

RESUMEN

It is known that Cinnamomum camphora seed oil (CCSO) is rich in medium-chain fatty acids (MCFAs) or medium-chain triacylglycerols (MCTs). The purpose of the present study was to produce zero-trans MCTs-enriched plastic fat from a lipid mixture (500 g) of palm stearin (PS) and CCSO at 3 weight ratios (PS:CCSO 60:40, 70:30, 80:20, wt/wt) by using lipase (Lipozyme TL IM, 10% of total substrate) as a catalyst at 65 °C for 8 h. The major fatty acids of the products were palmitic acid (C16:0, 42.68% to 53.42%), oleic acid (C18:1, 22.41% to 23.46%), and MCFAs (8.67% to 18.73%). Alpha-tocopherol (0.48 to 2.51 mg/100 g), γ-tocopherol (1.70 to 3.88 mg/100 g), and δ-tocopherol (2.08 to 3.95 mg/100 g) were detected in the interesterified products. The physical properties including solid fat content (SFC), slip melting point (SMP), and crystal polymorphism of the products were evaluated for possible application in shortening or margarine. Results showed that the SFCs of interesterified products at 25 °C were 9% (60:40, PS:CCSO), 18.50% (70:30, PS:CCSO), and 29.2% (80:20, PS:CCSO), respectively. The ß' crystal form was found in most of the interesterified products. Furthermore, no trans fatty acids were detected in the products. Such zero-trans MCT-enriched fats may have a potential functionality for shortenings and margarines which may become a new type of nutritional plastic fat for daily diet.

RESUMEN

BACKGROUND: Results from prospective cohort studies and randomized, controlled trials have provided evidence of a protective effect of n-3 fatty acids against cardiovascular diseases. We examined the effect of the marine n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and of the plant-derived alpha-linolenic acid (ALA) on the rate of cardiovascular events among patients who have had a myocardial infarction. METHODS: In a multicenter, double-blind, placebo-controlled trial, we randomly assigned 4837 patients, 60 through 80 years of age (78% men), who had had a myocardial infarction and were receiving state-of-the-art antihypertensive, antithrombotic, and lipid-modifying therapy to receive for 40 months one of four trial margarines: a margarine supplemented with a combination of EPA and DHA (with a targeted additional daily intake of 400 mg of EPA-DHA), a margarine supplemented with ALA (with a targeted additional daily intake of 2 g of ALA), a margarine supplemented with EPA-DHA and ALA, or a placebo margarine. The primary end point was the rate of major cardiovascular events, which comprised fatal and nonfatal cardiovascular events and cardiac interventions. Data were analyzed according to the intention-to-treat principle, with the use of Cox proportional-hazards models. RESULTS: The patients consumed, on average, 18.8 g of margarine per day, which resulted in additional intakes of 226 mg of EPA combined with 150 mg of DHA, 1.9 g of ALA, or both, in the active-treatment groups. During the follow-up period, a major cardiovascular event occurred in 671 patients (13.9%). Neither EPA-DHA nor ALA reduced this primary end point (hazard ratio with EPA-DHA, 1.01; 95% confidence interval [CI], 0.87 to 1.17; P=0.93; hazard ratio with ALA, 0.91; 95% CI, 0.78 to 1.05; P=0.20). In the prespecified subgroup of women, ALA, as compared with placebo and EPA-DHA alone, was associated with a reduction in the rate of major cardiovascular events that approached significance (hazard ratio, 0.73; 95% CI, 0.51 to 1.03; P=0.07). The rate of adverse events did not differ significantly among the study groups. CONCLUSIONS: Low-dose supplementation with EPA-DHA or ALA did not significantly reduce the rate of major cardiovascular events among patients who had had a myocardial infarction and who were receiving state-of-the-art antihypertensive, antithrombotic, and lipid-modifying therapy.

RESUMEN

OBJECTIVE: Our purpose was to examine the effects of daily servings of butter, no-trans-fat margarine and plant sterol margarine, within recommended amounts, on plasma lipids, apolipoproteins (Apos), biomarkers of inflammation and endothelial dysfunction, and on the transfer of lipids to HDL particles in free-living subjects with the metabolic syndrome. METHODS: This was a randomized, single-blind study where 53 metabolic syndrome subjects (62% women, mean age 54 years) received isocaloric servings of butter, no-trans-fat margarine or plant sterol margarine in addition to their usual diets for 5 weeks. The main outcome measures were plasma lipids, Apo, inflammatory and endothelial dysfunction markers (CRP, IL-6, CD40L or E-selectin), small dense LDL cholesterol concentrations and in vitro radioactive lipid transfer from cholesterol-rich emulsions to HDL. Difference among groups was evaluated by analysis of variance. RESULTS: There was a significant reduction in Apo-B (-10.4 %, P=0.043) and in the Apo-B/Apo-A-1 ratio (-11.1%, P=0.034) with plant sterol margarine. No changes in plasma lipids were noticed with butter and no-trans-fat margarine. Transfer rates of lipids to HDL were reduced in the no-trans-fat margarine group: triglycerides -42.0%, (P<0.001 vs butter and sterol margarine) and free cholesterol -16.2% (P=0.006 vs sterol margarine). No significant effects were noted on the concentrations of inflammatory and endothelial dysfunction markers among the groups. CONCLUSIONS: In free-living subjects with the metabolic syndrome consumption of plant sterol and no-trans-fat margarines within recommended amounts reduced, respectively, Apo-B concentrations and the ability of HDL to accept lipids.

RESUMEN

La margarina es fuente de ácidos grasos saturados (AGS), insaturados y trans (AGT) en la dieta diaria, estos son incorporados en los fosfolípidos de las membranas celulares. Nos planteamos un estudio experimental de los efectos de los AGS y AGT de la margarina en la cinética de potenciación posreposo ventricular derecha y el cronotropismo auricular en corazón de rata. Tres grupos de ratas Sprague-Dawley recibieron alimento estándar enriquecido con aceite de soya o margarina, respectivamente, por 4 semanas. Se estudió el cronotropismo auricular utilizando dosis crecientes de Epinefrina y en ventrículo derecho, la fuerza de estado estable y la potenciación post-reposo en presencia y ausencia de Verapamil. Las dietas enriquecidas con margarina disminuyeron significativamente (P<0,05) la fuerza contráctil del estado estable y la cinética de potenciación post-reposo en comparación a las otras dietas mientras que no se encontró diferencias en el cronotropismo auricular


Margarine is a source of saturated fatty acids (SFA), unsaturated and trans (TFA) in daily diet, these are incorporated into the cell membranes phospholipids. We considered an experimental study about the effects of margarine’s SFA and TFA on the right ventricle post-rest potentiation kinetics and atrial chronotropism in rat heart. Three groups of Sprague- Dawley rats received standard food enriched with soybean oil or margarine, respectively, for 4 weeks. We studied the atrial chronotropism using increasing doses of epinephrine and in right ventricle, steady-state force and post-rest potentiation in presence and absence of Verapamil. Margarine-enriched diets significantly reduced (p<0,05) contractile force in steady-state and post-rest potentiation kinetics in comparison to other diets, while no differences were found in atrial chronotropism

RESUMEN

Clinical safety of consuming plant stanol ester spreads during pregnancy and lactation, the impact on maternal and infant serum and breast-milk cholesterol and the ratios (micromol/mmol of cholesterol) of synthesis and absorption markers were evaluated. Pregnant women (n 21) were randomised to control and dietary intervention groups, the intervention including advice to follow a balanced diet and to consume spreads enriched with plant stanol esters. Participants were followed during and after pregnancy and their infants up to 1 year of age. A mean 1.1 (sd 0.4) g consumption of plant stanols during pregnancy and 1.4 (sd 0.9) g 1 month post-partum increased sitostanol and the markers for cholesterol synthesis, lathosterol, lathosterol/campesterol and lathosterol/sitosterol, and reduced a marker for cholesterol absorption, campesterol, in maternal serum. In breast milk, desmosterol was lower in the intervention group, while no differences were detected between the groups in infants' serum. Plant stanol ester spread consumption had no impact on the length of gestation, infants' growth or serum beta-carotene concentration at 1 and 6 months of age, but the cholesterol-adjusted serum beta-carotene concentration was lowered at 1 month in the intervention group. Plant stanol ester spread consumption appeared safe in the clinical setting, except for potential lowering of infants' serum beta-carotene concentration, and was reflected in the markers of cholesterol synthesis and absorption in mothers' serum, encouraging further studies in larger settings.

RESUMEN

BACKGROUND: Masked allergens in processed food products can lead to severe allergic reactions following unintentional ingestion. We sought to develop a murine model for the detection of hidden cow's milk proteins (CMP). This study aimed to induce cow's milk allergy in mice, to characterize the anaphylaxis induced by CMP in this model, and to validate its reliability using three margarines manufactured with (A) or without (B, C) milk, sharing the same production line. MATERIALS AND METHODS: Three-week-old BALB/c mice were sensitized intragastrically with CMP plus cholera toxin and boosted 6 times at weekly intervals. CMP-sensitization status was monitored by skin tests, and measurement of CMP-specific IgE and IgG1 levels. On day 44, the minimal threshold of clinical reactivity to CMP in terms of anaphylaxis was determined by performing a dose response of intraperitoneal CMP challenge. Under the same conditions, anaphylaxis was evaluated in CMP-sensitized mice after challenge with protein extracts of margarines A, B or C. RESULTS: Sensitization to CMP was demonstrated by positive skin tests and increased CMP-specific IgE and IgG1. The minimal clinical reactivity threshold corresponding to 0.1 mg CMP elicited detectable anaphylaxis evidenced by clinical symptoms, a decrease in breathing frequency, and increased plasma histamine upon challenge. Similarly, challenges with margarine A containing CMP demonstrated anaphylaxis, whereas those with B or C did not elicit any detectable allergic reaction. CONCLUSION: This study shows that our murine model of CMP-induced anaphylaxis is useful for investigating the allergenic activity and the assessment of margarines with respect to milk.

RESUMEN

At the start of the 20th century, the production of trans fatty acids was originally largely driven by the increasing demand for margarine. The two Dutch margarine firms Van den Bergh and Jurgens played an important role in this early development. In the early 1990s it was shown that trans fatty acids increase the risk of heart disease. Unilever, the successor to Van den Bergh and Jurgens, then took the lead in eliminating trans fatty acids from retail foods worldwide. As a result, intake in The Netherlands fell from 15 g per day in 1980 to 3 g per day in 2003. Dairy products and meat are now the major source of trans fatty acids. The effects on health of these ruminant trans fatty acids are unclear. There are three lessons to be learned from the rise and fall of trans fatty acids. First, a history of safe use does not guarantee safety of food components, because routine surveillance will fail to detect adverse effects on common illnesses with long incubation periods. Second, it shows that it is more effective and easier to change the composition of foods than to change consumer behaviour. And third, governments can have a major impact on consumers' health by mandating the use of healthier food ingredients.

RESUMEN

UNLABELLED: The aim of the present study performed in a Romanian population was to identify the food which can be either associated with or protect against colorectal carcinoma. MATERIAL AND METHOD: Correlation and regression analysis were used to examine the association between dietary intake and the rate of incidence for colon, rectum and anus cancers, in study groups from 7 regions of Romania. RESULTS: A strong and positive association was observed for colonic cancer and the intake of coffee, tea and cocoa (r = 0.77, p = 0.042) whereas statistical significance of borderline value was found for margarine (r = 0.73, p = 0.06) and sweets (r = 0.74, p = 0.066) intake. A potential protective effect can be attributed to wine consumption ( r = -0.75, p = 0.03). The malignancies of the rectum and anus showed both a strong positive correlation with the intake of red meat ( r = 0.76, p = 0.048), sausages ( r = 0.87, p = 0.012), margarine (r = 0.97, p = 0.0004), butter ( r = 0.76, p = 0.049), sweets ( r = 0.93, p = 0.003), beverages (r = 0.97, p = 0.0003), coffee, tea, cocoa ( r = 0.94, p = 0.002). Negative correlations were reported for the recto-anal cancer and the consumption of: fish (r = -0.8, p = 0.032), cheese (r = -0.9, p = 0.006), wine (r = -0.85, p = 0.015). CONCLUSION: The need for reducing the dietary intake of margarine, red meat, sausages and sweets while the beneficial effects of wine consumption have been also confirmed.

RESUMEN

Mensink and Katan showed in 1990 that trans fats reduce high- and increase low-density lipoprotein cholesterol. Unilever aided this study because the company considered knowledge on trans fats incomplete in spite of their long history of safe use. The decision in 1994 to remove trans fats from Unilever's retail spreads was triggered by media events, but it was built on a solid understanding of the nutritional and technological aspects of trans fats. Over the next 14 years, manufacturers worldwide followed suit. This experience illustrates that food companies need to know about the health effects of their products and how to apply that knowledge.
