Olive Oil: Nutritional Applications, Beneficial Health Aspects and its Prospective Application in Poultry Production

Abstract

Plant polyphenols have promoting health features, including anti-mutagenic, anti-inflammatory, anti-thrombotic, anti-atherogenic, and anti-allergic effects. These polyphenols improve the immune system by affecting the white blood cell proliferation, as well as by the synthesis of cytokines and other factors, which contribute to immunological resistance. Olive trees are one of the most famous trees in the world. Whereas, olive olive oil and derivatives represent a large group of feeding resource for farm animals. In recent years, remarkable studies have been carried out to show the possible use of olive oil and derivatives for improvement of both animal performance and product quality. In vivo application of olive oil and its derived products has shown to maintain oxidative balance owing to its polyphenolic content. Consumption of extra virgin olive oil reduces the inflammation, limits the risk of liver damage, and prevents the progression of steatohepatitis through its potent antioxidant activities. Also, the monounsaturated fatty acids content of olive oil (particularly oleic acid), might have positive impacts on lipid peroxidation and hepatic protection. Therefore, this review article aims to highlight the nutritional applications and beneficial health aspects of olive oil and its effect on poultry production.

Olive oil consumption and risk of cardiovascular disease and all-cause mortality: A meta-analysis of prospective cohort studies

“…Olive oil, an essential ingredient of the Mediterranean diet pattern, is widely used for cooking and dressing in traditional Mediterranean regions. In addition to its high content of monounsaturated fats acids (MUFAs), olive oil is abundant in other nutrients such as phenolic compounds, vitamin E, and lipid molecules that possess anti-inflammatory and antioxidant effects ( 1 ). Owing to these potential health-promoting properties, olive oil has become more popular worldwide in recent years.…”

“…Their advantages include bioactivity, easy availability, specific response, and hypotoxicity [ 119 ]. And the public pay close attention to polyphenols because of their ability to oxidative coupling reaction in recent years [ 120 – 122 ]. In addition, rapid metabolism and low bioavailability are their insufficiency [ 123 ].…”

“…As a result of the growing concern over antibiotic resistance for several microorganisms resulting from subtherapeutic usage in animals, the use of medicinal plants for animal production and human health is expanding globally ( Roy Chowdhury et al, 2014 ; Bilal et al, 2021 ; Arif et al, 2022 ). Numerous studies have been conducted addressing different medicinal plants, herbs, and their byproducts (extracts and powders) as novel feed supplements, functional foods, and nutraceuticals in the poultry ( Gong et al, 2013 ; Zeng et al, 2015 ; Ghanima et al, 2020 ; Jamil et al, 2022 ) exerting several beneficial effects such as growth and nutrient absorption enhancers, antioxidants, immune boosters, antimicrobials, antiparasitic and health-protecting agents ( Abd El-Hack et al, 2020 ; Attia et al, 2020 ; Elbaz et al, 2021 ; Saleh et al, 2022 ).…”
