Corn oil improves the plasma lipoprotein lipid profile compared with extra-virgin olive oil consumption in men and women with elevated cholesterol: Results from a randomized controlled feeding trial

Abstract

Consumption of CO in a weight-maintenance, low saturated fat and cholesterol diet resulted in more favorable changes in LDL-C and other atherogenic lipids vs EVOO.

MediterrAsian Diet Products That Could Raise HDL-Cholesterol: A Systematic Review

“…Regarding the study design, out of the 15 studies, two were randomized, double-blind, placebo-controlled, and parallel-groups trials [32, 42], two were randomized, double-blind, and controlled clinical trials [30, 35], one was a randomized and double-blind trial [39], one was a randomized, controlled, and parallel study [44], one was a randomized, double-blind, and controlled crossover feeding trial [31], one was a randomized and single-blind crossover trial [33], two were randomized and controlled crossover studies [34, 38], one was a randomized and intervention crossover trial [36], two were double-blind crossover studies [37, 43], and two were pre-post studies [40, 41]. …”

“…Regarding the control group, two studies used DHA [30, 32], one study used corn oil [31], two studies used low polyphenol olive oil [34, 36], one used virgin argan oil [44], and one used fish oil [30]. One study [33] had three control groups (Group A: EPA: 3 g/day; Group B: DHA: 3 g/day; Group C: fish oil: 3 g/day).…”

“…Four studies [30, 33, 36, 42] included subjects with hypercholesterolemia or moderate hypercholesterolemia; seven studies [37–41, 43, 44] included subjects with normal lipid levels, one study [32] included subject with adherence to a vegetarian diet for at least one year, and two studies [34, 35] included healthy males and healthy volunteers.…”

“…One crossover study [43] showed a significant difference in HDL-C levels in two out of the three intervention groups ( P < 0.05 in Group A and Group B). In the other three studies [30, 31, 36], no significant changes were observed, but it has to be considered that the selected population was characterized by normal or slightly increased TC values (5,81, 5.32, and 4.19 mmol/L) and with an HDL, respectively, equal to 1.21, 1.09, and 1.52 mmol/L. In addition, these studies included a small sample of participants (57, 54, and 46 subjects).…”

Effect of adding inulin as a partial substitute for corn oil on the physicochemical and microbiological characteristics during processing of dry-fermented chicken sausage

“…Corn oil is composed mainly (99% of the refined or 96% of the crude oil) of acylglycerols (mono‐, di‐ and primarily tri‐), and has 59% polyunsaturated (PUFA), 24% monounsaturated (MUFA) and only 13% saturated fatty acid (SFA) (Si et al, ). Furthermore, it contains the highest naturally occurring phytosterol levels of the refined vegetable oils (0.97 g/100 g oil) and it presents significant amounts of tocopherols (vitamin E) (Maki, Lawless, Kelley, Kaden, Geiger, & Dicklin, ). Therefore, the use of poultry meat and corn oil in the preparation of dry‐fermented sausages would result in a healthier product.…”
