Background: Prospective studies have shown generally null associations between overall saturated fat consumption and CVD events. Understanding whether food sources of saturated fatty acids (SF) influence these relationships may help explain inconsistencies and provide insights as to underlying mechanisms. Objective and Hypothesis: We investigated associations between SF consumption from different major dietary sources (SF from each of meat, dairy, fats/oils, and plants) and CVD incidence in the Multi-Ethnic Study of Atherosclerosis (MESA). We hypothesized that associations between SF and CVD incidence would be influenced by the food sources delivering SF. Methods: Participants 45–84 years of age at baseline (n = 5,209) were followed between 2000 and 2007. Dietary intake was assessed using a 120-item food frequency questionnaire. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% CIs for incident CVD (275 cases) across categories of energy-adjusted intakes of SF by food source. Energy density substitution models were used to estimate the effect of substituting a percentage of energy intake from a specific SF source for the same amount of SF from another source. All models were adjusted for demographics, behavioral and dietary confounders such as intakes of fruit and vegetables, fiber, trans-fat and PUFA. Results: After multivariable adjustment, each 1-g greater intake of meat SF corresponded to 5% higher risk of CVD (HR [CI] per 1-g: 1.05 [1.01– 1.10]). In contrast, each 1-g greater intake of dairy SF intake corresponded to 4% lower risk of CVD (HR [CI] per 1-g: 0.96 [0.93– 0.99]). Substituting 1% of energy from meat SF with energy from dairy SF was associated with a 14% reduction in CVD risk (HR [CI]: 0.86 [0.78–0.95]). The replacements of energy from meat SF with fats/oils SF or with plant SF did not show statistically significant impacts on relative estimates of CVD risk (HR [CI]: 0.93 [0.83–1.05] and 0.93 [0.59 to 1.46], respectively), and neither intake of fats/oils SF nor intake of plant SF was independently associated with CVD risk. Conclusion: These findings suggest that associations between SF and CVD may depend on known differences in type of saturated fatty acids contained in specific food sources or other non-SF constituents in these sources.

Dietary recommendations to decrease the risk of cardiovascular disease (CVD) have focused on reducing intake of saturated fatty acids (SFA) for more than 50 years. While the 2015-2020 Dietary Guidelines for Americans advise substituting both monounsaturated and polyunsaturated fatty acids for SFA, evidence supports other nutrient substitutions that will also reduce CVD risk. For example, replacing SFA with whole grains, but not refined carbohydrates, reduces CVD risk. Replacing SFA with protein, especially plant protein may also reduce CVD risk. While dairy fat (milk, cheese) is associated with a slightly lower CVD risk compared to meat, dairy fat results in a significantly greater CVD risk relative to unsaturated fatty acids. As research continues, we will refine our understanding of dietary patterns associated with lower CVD risk.

The 2019 revised version of Canada’s Food Guide (CFG) recommends limiting the consumption of processed foods that are high in saturated fatty acids (SFA). Yet, the contributions of each CFG group to the total SFA intake of Canadians are not specifically known. The objectives of this study were to quantify the total SFA intake of Canadians, determine the sources of SFA consumed by Canadian adults, and identify potential differences in these sources. A nation representative sample from the Canadian Community Health Survey (CCHS – Nutrition 2015) was used for these analyses. Dietary intakes were measured using a single 24-h recall. Food sources of SFA were classified according to the revised 2019 CFG categories. We have also examined the contribution of foods not included in these three categories to total SFA intake. Among Canadian adults, total SFA contributed to 10.4 ± 0.1% (SE) of total energy intake (E). The “Protein foods” (47.7 ± 0.5% with 23.2 ± 0.4% from milk and alternatives and 24.5 ± 0.4% from meats and alternatives) and “All other foods” (44.2 ± 0.5%) categories were the main sources of total SFA intake. Few differences in SFA sources were identified between sexes, age groups, education levels, and body mass index (BMI) categories. These data show that the mean SFA consumption is greater than the 10% E cut-off previously proposed in Canada. Future studies should examine which food substitution is most likely to contribute to a greater reduction in SFA intake at the population level.

Fish and seafood are excellent sources of nutrients such as omega-3 fatty acids, Vitamin D, and selenium. The aims of this study were to examine the pattern of seafood consumption among Canadians and determine their contribution to intakes of energy and nutrients. Day-1 24-h dietary recalls data collected from a national survey, the Canadian Community Health Survey—Nutrition in 2004 and 2015, were used to estimate food and nutrient intakes among Canadians. Seafood was classified according to the Bureau of Nutritional Sciences food list. Descriptive statistics were used to calculate the consumption rate and the average consumption amount of seafood by different age groups and sociodemographic characteristics. Population ratios were used to assess the contribution of seafood to the total intake of energy and nutrients. The overall consumption rate of seafood was around 17%, and the rate was similar between males and females, and slightly higher in 2015 (17.71%) compared to 2004 (16.38%). The average portion size is approximately 100 g, which translates into a ≈36 kg annual intake among the consumers and ≈6.2 kg per capita consumption. Adults (especially 30 years and above), Asians, individuals who were married, and with post-secondary education were more likely to consume seafood. Salmon, tuna, shrimp, cod, and crab were the most frequently consumed seafood in Canada, the consumption rate of which all increased from 2004 to 2015. Seafood provided up to 75% of n-3 PUFAs, 18% of Vitamin D, 19% Vitamin B12, 6% of niacin, and 4% of Vitamin B6 from all food sources. Seafood consumers had a healthier diet, as seafood consumption was related to a higher intake of key nutrients and a lower intake of total sugar and saturated fatty acids. Therefore, fish consumption should be promoted among Canadians.

Dietary intakes of polyunsaturated, monounsaturated and saturated fatty acids (FAs) have been inconsistently associated with puberty timing. We examined longitudinal associations of prepubertal dietary and plasma phospholipid FAs with several puberty timing traits in boys and girls. In the Avon Longitudinal Study of Parents and Children, prepubertal fat intakes at 3–7.5 years and plasma phospholipid FAs at 7.5 years were measured. Timings of Tanner stage 2 genital or breast development and voice breaking or menarche from repeated reports at 8–17 years, and age at peak height velocity (PHV) from repeated height measurements at 5–20 years were estimated. In linear regression models with adjustment for maternal and infant characteristics, dietary substitution of polyunsaturated FAs for saturated FAs, and higher concentrations of dihomo-γ-linolenic acid (20:3n6) and palmitoleic acid (16:1n7) were associated with earlier timing of puberty traits in girls (n = 3872) but not boys (n = 3654). In Mendelian Randomization models, higher genetically predicted circulating dihomo-γ-linolenic acid was associated with earlier menarche in girls. Based on repeated dietary intake data, objectively measured FAs and genetic causal inference, these findings suggest that dietary and endogenous metabolic pathways that increase plasma dihomo-γ-linolenic acid, an intermediate metabolite of n-6 polyunsaturated FAs, may promote earlier puberty timing in girls.

Meat is highly nutritious and contributes with several essential nutrients which are difficult to obtain in the right amounts from other food sources. Industrially processed meat contains preservatives including salts, possibly exerting negative effects on health. During maturation, some processed meat products develop a specific microbiota, forming probiotic metabolites with physiological and biological effects yet unidentified, while the concentration of nutrients also increases. Meat is a source of saturated fatty acids, and current WHO nutrition recommendations advise limiting saturated fat to less than ten percent of total energy consumption. Recent meta-analyses of both observational and randomized controlled trials do not support any effect of saturated fat on cardiovascular disease or diabetes. The current evidence regarding the effect of meat consumption on health is potentially confounded, and there is a need for sufficiently powered high-quality trials assessing the health effects of meat consumption. Future studies should include biomarkers of meat intake, identify metabolic pathways and include detailed study of fermented and other processed meats and their potential of increasing nutrient availability and metabolic effects of compounds.

The effect of dietary conjugated linoleic acid (CLA) in association with two vegetable oil sources on the fatty acids of meat and giblets of broiler chickens was evaluated. Two hundred 21-day-old broiler chickens were distributed in a completely randomized factorial design 2 x 5 (two oil sources, soybean or canola oil; and five levels of CLA, 0.0, 2.5, 5.0, 7.5, and 10.0g/kg). The addition of CLA to the diet resulted in an increase (P<0.05) in CLA deposition in the analyzed tissues. CLA supplementation also reduced (P<0.05) the rate of polyunsaturated to saturated fatty acids in thigh, breast, heart, and gizzard. There was interaction of CLA x oil source (P<0.05). The intake of soybean oil, associated with increasing CLA, resulted in an increase in lipid deposition in edible portions as observed by an increase in the overall content of fatty acids, including CLA, while the use of canola oil, associated with increasing CLA in the diet, resulted in a decrease in lipid content in edible portions, specifically regarding that of saturated fat (P<0.05) in breast meat and liver and in the content of monounsaturated fatty acids (P<0.05) in thigh, breast, liver, and gizzard.

Lifestyle is a key modifiable risk factor involved in the manifestation of metabolic syndrome and, in particular, diet plays a pivotal role in its prevention and development. Current dietary guidelines discourage the consumption of saturated fat and dietary sources rich in saturated fat, such as dairy products, despite data suggesting that full-fat dairy consumption is protective against metabolic syndrome. This narrative review assessed the recent epidemiological and clinical research that examined the consumption of dairy-derived saturated fatty acids (SFA) on metabolic syndrome risk. In addition, this review evaluated studies of individual SFA to gain insight into the potential mechanisms at play with intake of a diet enriched with these dairy-derived fatty acids. This work underscores that SFA are a heterogenous class of fatty acids that can differ considerably in their biological activity within the body depending on their length and specific chemical structure. In summary, previous work on the impact of dairy-derived SFA consumption on disease risk suggests that there is currently insufficient evidence to support current dietary guidelines which consolidate all dietary SFA into a single group of nutrients whose consumption should be reduced, regardless of dietary source, food matrix, and composition.

The objective of the present study was to describe the intake of dietary fatty acids among healthy 15-year-old boys and girls and to relate the intake of specific fatty acids and the fatty acid composition of the serum cholesterol esters to serum lipid, apolipoprotein (Apo) and insulin concentrations respectively. Fifty-two girls and forty-two boys were randomly selected from the official population register. Unexpectedly, significant inverse associations were found between the dietary content of saturated fatty acids with a chain length of four to fifteen C atoms, mainly derived from milk fat, as well as the corresponding fatty acids in the serum cholesterol esters, on the one hand and the serum concentrations of cholesterol and ApoB on the other. The estimated dietary intake of 4:0–10:0, 12:0 and 14:0 respectively, were all significantly inversely related to the serum cholesterol (r-0.32,r-0.31,r-0.30, all P<0.05) and ApoB (r-0.42,r-0.42, andr-0.40, all P<0.05) concentrations in girls and 12:0 to the ApoB concentration (r-0.55, P<0.01) in boys. The proportions of 12:0 and 15:0 in the serum cholesterol esters were negatively correlated with the serum cholesterol concentrations in both girls (r-0.34,r-0.32, P<0.05) and boys (r-0.53, P<0.01;r-0.32, P<0.05) and with the ApoB concentrations among boys (r-0.61, P<0.01;r-0.43, P<0.05). It is conceivable that milk fat contains or is associated with some component in the diet, or some other characteristics of the food intake, which counterbalances the expected positive relationships between saturated fat intake and lipid levels.

Introduction: The associations of dietary total fatty acids and the classes saturated, monounsaturated, and polyunsaturated fatty acids (SFAs, MUFAs, and PUFAs) with coronary heart disease (CHD) remain contentious. Moreover, the role of isocaloric macronutrient substitutions and specific food sources of SFAs, particularly in European context, is unclear. Hypothesis: We evaluated the hypothesis that associations of dietary fatty acids vary depending on specific macronutrient substitutions and food sources of SFAs. Methods: We conducted case-cohort analyses including 10,529 incident CHD cases and a random subcohort of 16,730 men and women selected from 385,747 eligible participants in nine countries of the European Prospective Investigation into Cancer and Nutrition Study. Habitual diet was assessed using country-specific dietary questionnaires, and macronutrient intakes were estimated using standardised nutrient databases. Country-specific HRs (95% CIs) per 5% energy intake from dietary total fatty acids, SFAs, MUFAs, and PUFAs were estimated using Prentice-weighted Cox regression models and pooled using random-effects meta-analyses, with and without considering isocaloric macronutrient substitutions. The associations of dietary SFAs from different food sources, including specific macronutrient substitutions, with CHD were also investigated. Results: There was no evidence of associations of dietary total fatty acids, SFAs, MUFAs, or PUFAs with incident CHD, regardless of the substitution macronutrient. Each 1% higher energy intake of SFAs from yoghurt, cheese, and fish were associated with a 7% (95% CI 1-12%), 2% (0-4%) and 13% (0-25%) lower CHD incidence, while SFAs from red meat and butter were associated with a 7% (2-12%) and 2% (0-4%) higher CHD incidence, respectively. Conclusions: There was no evidence of associations of dietary total fatty acids, SFAs, MUFAs, and PUFAs, with CHD incidence, regardless of the substitution nutrients, within the range of intakes in this European population. The opposite direction of associations of SFAs from different food sources such as red meat versus fermented dairy products suggests that public health recommendations should consider foods and overall diets, alongside the macronutrients they contain.

ABSTRACT Background Pinto beans contain multiple active agents such as polyphenols, flavonoids, and saponins, and have been shown to lower cholesterol, but the mechanisms involved in this effect have not been explored. Objective This study was to investigate the changes in cholesterol metabolism in response to whole pinto beans (wPB) and their hulls (hPB) supplemented into a diet rich in saturated fat and the molecular mechanisms potentially responsible for these effects in hamsters. Methods Forty-four 9-wk-old male Golden Syrian hamsters were randomly assigned to 4 diet groups (n = 11), including a 5% (wt:wt) fat diet [normal-fat diet (NF)], a 15% (wt:wt) fat diet [diet rich in saturated fat (HSF), saturated fatty acids accounted for 70% of total fatty acids], or HSF supplemented with 5% (wt:wt) wPB or 0.5% (wt:wt) hPB for 4 wk. Plasma, liver, intestinal, and fecal samples were collected to evaluate multiple cholesterol markers and gene targets. Results The plasma non-high-density lipoprotein (non-HDL) concentration was significantly reduced in the wPB- and hPB-supplemented groups by 31.9 ± 3.5% and 53.6 ± 3.2%, respectively, compared with the HSF group (P < 0.01), to concentrations comparable with the NF group. The wPB-supplemented hamsters had significantly lower liver cholesterol (45.1%, P < 0.001) and higher fecal cholesterol concentrations (94.8%, P = 0.001) than those fed the HSF. The expressions of hepatic 3-hydroxy-3-methylglutaryl CoA reductase (Hmgcr) and small intestinal acyl-coenzyme A: cholesterol acyltransferase 2 (Acat2) were significantly decreased in animals administered wPB (by 89.1% and 63.8%, respectively) and hPB (by 72.9% and 47.7%, respectively) compared with their HSF-fed counterparts (P < 0.05). The wPB normalized the expression of Acat2 to the level of the NF group. Conclusion Pinto beans remediated high cholesterol induced by HSF in male hamsters by decreasing hepatic cholesterol synthesis and intestinal cholesterol absorption, effects which were partially exerted by the hulls.
