Abstract
Background Cardiovascular disease (CVD) affects millions worldwide and is the leading cause of death among non-communicable diseases. Western diets typically comprise of meat and dairy products, both of which are rich in cholesterol (Cho) and methionine (Met), two well-known compounds with atherogenic capabilities. Despite their individual effects, literature on a dietary combination of the two in the context of CVD are limited. An additional interest was to investigate the cardioprotective potential of sitagliptin, an anti-type 2 diabetic drug. Thus, we hypothesized that atherogenic feeding would result in adverse cardiac effects and would attenuate upon sitagliptin administration. Methods Six-week-old adult male Sprague-Dawley rats were fed either a control (Con), high Met (1.5%), high Cho (2.0%), or high Met (1.5%) + high Cho (2.0%) diet for 35 days. They were orally gavaged with vehicle (water) or sitagliptin (100 mg/kg/d) from day 10 through 35. On day 36, rats were euthanized, and tissues were collected for analysis. Results Histopathological evaluation revealed a reduction in myocardial striations and increased collagen deposition in hypercholesterolemia (HChol), responses that became exacerbated upon sitagliptin administration. Cardiac pro-inflammatory and pro-fibrotic responses were adversely impacted in similar fashion. The addition of Met to Cho (MC) attenuated all adverse structural and biochemical responses, with or without sitagliptin. Conclusion Adverse cardiac outcomes in HChol were enhanced with sitagliptin administration and such effects were alleviated by Met. Our findings could be significant for understanding the risk-benefit of sitagliptin in type 2 diabetics who are known to consume atherogenic diets.

Agroindustrial valorization of the pulp and peel, seed, flour, and oil of moriche ( Mauritia flexuosa) from the Bita River, Colombia: a potential source of essential fatty acids. BIOMASS CONVERSION AND BIOREFINERY 2022; 13:1-9. [PMID: 35039789 PMCID: PMC8754474 DOI: 10.1007/s13399-022-02298-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 12/28/2021] [Accepted: 01/02/2022] [Indexed: 06/14/2023]
Abstract
The expansion of the agricultural frontier in the eastern llanos region of Colombia has endangered the moriche palm (Mauritia flexuosa) which has an important ecological function and provides various ecosystem services. In particular, the moriche that grows in this region is wild and has been little studied; therefore, there are no reports of its potential as a source of monounsaturated and polyunsaturated fatty acids, information that could be useful for the conservation of the species. This study performed a physicochemical characterization of the oil extracted from the dried pulp of moriche and identified the fatty acids present in the oil, pulp and peel, seed, and flour of this fruit from the Bita River Basin, Vichada, Colombia. The fatty acid composition was characterized by gas chromatography, including physicochemical tests of interest in the oil according to AOCS protocols. The results showed that the highest fatty acid content was found in the extracted oil, with a distribution of 81.64% unsaturated fat and 18.36% saturated fat. These fats included 79.20% oleic acid (omega-9), 0.26% palmitoleic acid (omega-7), 1.01% linoleic acid (omega-6), 1% linolenic acid (omega-3), 16.91% palmitic acid, and 1.33% stearic acid. We conclude that moriche from Bita Basin is an oleaginous fruit due to its high nutritional value in terms of unsaturated fatty acids and that both the flour and the oil obtained are bioproducts with potential industrial application.

Gutiérrez-Luna K, Ansorena D, Astiasarán I. Flax and hempseed oil functional ingredient stabilized by inulin and chia mucilage as a butter replacer in muffin formulations. J Food Sci 2020; 85:3072-3080. [PMID: 32869333 DOI: 10.1111/1750-3841.15407] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 07/02/2020] [Accepted: 07/20/2020] [Indexed: 12/12/2022]
Abstract
The addition of different amounts of a functional ingredient composed of water, inulin, chia seeds, and hemp or flaxseed oil was examined as butter replacer to improve the nutritional value of muffins. Nutritional, technological, and sensory characteristics of the reformulated products were assessed, as well as the stability under storage at room temperature. One control and six modified formulations with three levels of butter replacement (50%, 75%, and 100%) were analyzed. Modified muffins improved their nutritional profile, reducing up to 78% of fat and increasing fiber (up to 62.5%) and omega-3 fatty acids content (from 0.12 g/100 g of product to 0.62 g and 1.55 g in hemp and flaxseed oil samples, respectively). Sensory analysis revealed that flaxseed oil samples were indistinguishable from the control in all evaluated attributes, even in the highest level of replacement. During storage, texture of modified samples behaved similar to the control and no oxidation problems were observed in any of the formulations. Therefore, the functional ingredient proved to be a feasible alternative for replacing butter in muffins, preserving the quality attributes and making them healthier foods. PRACTICAL APPLICATION: Functional ingredients including fiber and low amounts of good-quality sources of fat have a simple manufacturing process, do not require heating, and perform well once incorporated to the matrix. They are versatile and could be incorporated in other bakery products to substitute butter or even oil, to obtain a reduced calorie product and with an enhanced nutritional profile and good sensory properties.

Dietary Intake, Nutritional Adequacy and Food Sources of Total Fat and Fatty Acids, and Relationships with Personal and Family Factors in Spanish Children Aged One to <10 Years: Results of the EsNuPI Study. Nutrients 2020; 12:E2467. [PMID: 32824377 PMCID: PMC7468841 DOI: 10.3390/nu12082467] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 08/10/2020] [Accepted: 08/14/2020] [Indexed: 12/14/2022] Open
Abstract
We aimed to determine the usual intake of total fat, fatty acids (FAs), and their main food sources in a representative cohort of the Spanish pediatric population aged 1 to <10 years (n = 707) who consumed all types of milk and an age-matched cohort who consumed adapted milk over the last year (including follow-on formula, toddler's milk, growing-up milk, and fortified and enriched milks) (n = 741) who were participants in the EsNuPI study (in English, Nutritional Study in the Spanish Pediatric Population). Dietary intake, measured through two 24 h dietary recalls, was compared to the European Food Safety Authority (EFSA) and the Food and Agriculture Organization of the United Nations (UN-FAO) recommendations. Both cohorts showed a high intake of saturated fatty acids (SFAs), according to FAO recommendations, as there are no numerical recommendations for SFAs at EFSA. Also, low intake of essential fatty acids (EFAs; linoleic acid (LA) and α-linolenic acid (ALA)) and long-chain polyunsaturated fatty acids (LC-PUFA) of the n-3 series, mainly docosahexaenoic acid (DHA) were observed according to EFSA and FAO recommendations. The three main sources of total fat and different FAs were milk and dairy products, oils and fats, and meat and meat products. The consumption of adapted milk was one of the main factors associated with better adherence to the nutritional recommendations of total fat, SFAs, EFAs, PUFAs; and resulted as the main factor associated with better adherence to n-3 fatty acids intake recommendations. Knowledge of the dietary intake and food sources of total fat and FAs in children could help in designing and promoting effective and practical age-targeted guidelines to promote the consumption of EFA- and n-3 PUFA-rich foods in this stage of life.
