Conjugated linoleic acid (CLA) as a functional food: Is it beneficial or not? Food Res Int 2023; 172:113158. [PMID: 37689911 DOI: 10.1016/j.foodres.2023.113158] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 06/15/2023] [Accepted: 06/16/2023] [Indexed: 09/11/2023]
Abstract
Conjugated linoleic acid (CLA) has attracted great attention in recent years as a popular class of functional food that is broadly used. It refers to a group of geometric and positional isomers of linoleic acid (LA) with a conjugated double bond. The main natural sources of CLA are dairy products, beef and lamb, whereas only trace amounts occur naturally in plant lipids. CLA has been shown to improve various health issues, having effects on obesity, inflammatory, anti-carcinogenicity, atherogenicity, immunomodulation, and osteosynthesis. Also, compared to studies on humans, many animal researches reveal more positive benefits on health. CLA represents a nutritional avenue to improve lifestyle diseases and metabolic syndrome. Most of these effects are attributed to the two major CLA isomers [conjugated linoleic acid cis-9,trans-11 isomer (c9,t11), and conjugated linoleic acid trans-10,cis-12 isomer (t10,c12)], and their mixture (CLA mix). In contrast, adverse effects of CLA have been also reported, such as glucose homeostasis, insulin resistance, hepatic steatosis and induction of colon carcinogenesis in humans, as well as milk fat inhibition in ruminants, lowering chicken productivity, influencing egg quality and altering growth performance in fish. This review article aims to discuss the health benefits of CLA as a nutraceutical supplement and highlight the possible mechanisms of action that may contribute to its outcome. It also outlines the feasible adverse effects of CLA besides summarizing the recent peer-reviewed publications on CLA to ensure its efficacy and safety for proper application in humans.

Omega-3 and Omega-6 Fatty Acids in Poultry Nutrition: Effect on Production Performance and Health. Animals (Basel) 2019; 9:E573. [PMID: 31426600 PMCID: PMC6721126 DOI: 10.3390/ani9080573] [Citation(s) in RCA: 86] [Impact Index Per Article: 17.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Accepted: 08/16/2019] [Indexed: 01/10/2023] Open
Abstract
Omega-3 (ω-3) and omega-6 (ω-6) fatty acids are important components of cell membranes. They are essential for health and normal physiological functioning of humans. Not all fatty acids can be produced endogenously owing to the absence of certain desaturases; however, they are required in a ratio that is not naturally achieved by the standard diet of industrialized nations. Poultry products have become the primary source of long-chain polyunsaturated fatty acids (LC-PUFA), with one of the most effective solutions being to increase the accretion of PUFAs in chicken products via the adjustment of fatty acids in poultry diets. Several studies have reported the favorable effects of ω-3 PUFA on bone strength, bone mineral content and density, and semen quality. However, other studies concluded negative effects of LC-PUFA on meat quality and palatability, and acceptability by consumers. The present review discussed the practical application of ω-3 and ω-6 fatty acids in poultry diets, and studied the critical effects of these fatty acids on productive performance, blood biochemistry, immunity, carcass traits, bone traits, egg and meat quality, and semen quality in poultry. Future studies are required to determine how poultry products can be produced with higher contents of PUFAs and favorable fatty acid composition, at low cost and without negative effects on palatability and quality.

Abstract
Conjugated linoleic acid (CLA) has been shown to exert various potential physiological properties including anti-carcinogenic, anti-obesity, anti-cardiovascular and anti-diabetic activities, and consequently has been considered as a promising food supplement. Bacterial biosynthesis of CLA is an attractive approach for commercial production due to its high isomer-selectivity and convenient purification process. Many bacterial species have been reported to convert free linoleic acid (LA) to CLA, hitherto only the precise CLA-producing mechanisms in Propionibacterium acnes and Lactobacillus plantarum have been illustrated completely, prompting the development of recombinant technology used in CLA production. The purpose of the article is to review the bacterial CLA producers as well as the recent progress on describing the mechanism of microbial CLA-production. Furthermore, the advances and potential in the heterologous expression of CLA genetic determinants will be presented.

Dietary supplementation of a mixture of Lactobacillus strains enhances performance of broiler chickens raised under heat stress conditions. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2016; 60:1099-110.

Abstract
High ambient temperature is a major problem in commercial broiler production in the humid tropics because high producing broiler birds consume more feed, have higher metabolic activity, and thus higher body heat production. To evaluate the effects of two previously isolated potential probiotic strains (Lactobacillus pentosus ITA23 and Lactobacillus acidophilus ITA44) on broilers growing under heat stress condition, a total of 192 chicks were randomly allocated into four treatment groups of 48 chickens each as follows: CL, birds fed with basal diet raised in 24 °C; PL, birds fed with basal diet plus 0.1 % probiotic mixture raised in 24 °C; CH, birds fed with basal diet raised in 35 °C; and PH, birds fed with basal diet plus 0.1 % probiotic mixture raised in 35 °C. The effects of probiotic mixture on the performance, expression of nutrient absorption genes of the small intestine, volatile fatty acids (VFA) and microbial population of cecal contents, antioxidant capacity of liver, and fatty acid composition of breast muscle were investigated. Results showed that probiotic positively affected the final body weight under both temperature conditions (PL and PH groups) compared to their respective control groups (CL and CH). Probiotic supplementation numerically improved the average daily gain (ADG) under lower temperature, but significantly improved ADG under the higher temperature (P < 0.05) by sustaining high feed intake. Under the lower temperature environment, supplementation of the two Lactobacillus strains significantly increased the expression of the four sugar transporter genes tested (GLUT2, GLUT5, SGLT1, and SGLT4) indicating probiotic enhances the absorption of this nutrient. Similar but less pronounced effect was also observed under higher temperature (35 °C) condition. In addition, the probiotic mixture improved bacterial population of the cecal contents, by increasing beneficial bacteria and decreasing Escherichia coli population, which could be because of higher production of VFA in the cecum, especially at heat stress condition. The two Lactobacillus strains also improved the fatty acid profile of meat, including at heat stress. Generally, the two Lactobacillus strains can be considered as good potential probiotics for chickens due to their good probiotic properties and remarkable efficacy on broiler chickens.

Abstract
BACKGROUND Consumers are becoming increasingly interested in food containing high concentration of polyunsaturated fatty acids (PUFA). PUFA are considered as functional ingredients to prevent cardiovascular disease. The present study aimed to evaluate the effects of Clostridium butyricum on antioxidant properties, meat quality and fatty acid composition of broilers. METHODS A total of 320 one-day-old Arbor Acres male chicks were randomly assigned to one of five treatments with eight replicates and fed a antibiotic-free basal corn-soybean meal diet (control) or the basal diet supplemented with either 2.5 × 10(8) (CB1), 5 × 10(8) (CB2) or 1 × 10(9) (CB3) cfu of C. butyricum/kg or 150 mg of aureomycin/kg (antibiotic) for 42 days. RESULTS The results showed that chicks fed diets supplemented with C. butyricum had higher (P < 0.05) superoxide dismutase activity and lower (P < 0.05) malondialdehyde concentration in liver compared with those in the control group. Broilers had lower (P < 0.05) cholesterol content of serum in either CB2 or CB3 treatment at day 21 and in the C. butyricum-supplemented groups at day 42 than those in the control group. Chicks fed CB3 diet had lower (P < 0.05) percentage of abdominal fat and higher (P < 0.05) breast muscle yield than those in the control and antibiotic groups. The supplementation of C. butyricum increased (P < 0.05) the concentrations of C20:1n-9, C20:2n-6, C20:3n-6, C20:3n-3, C20:4n-6, C20:5n-3, C22:6n-3 and total PUFA as well as ratio of PUFA to saturated fatty acids in breast muscle and the contents of C18:2 t-9, t-12, C20:3n-6, C20:3n-3 and C20:5n-3 in thigh muscle. CONCLUSIONS Supplementation of C. butyricum promotes hepatic antioxidant status, decreases cholesterol content of serum and percentage of abdominal fat, and improves meat quality and fatty acid composition of broiler birds. The results from the present study indicate that the increased PUFA concentrations in meat of broilers fed C. butyricum might be attributable to enhanced antioxidant activity.
