The Consumption of Low Animal Food with Low n-6/n-3 Ratio Reduce LDL Cholesterol in Humans

The purpose of this study was to examine the effect on lowering LDL-C in a adult human by applying low animal foods with a lower n-6/n-3 ratio. It was found that the n-6/n-3 ratio was significantly lowered in the low Hanwoo beef, the low pork, the low chicken, the low egg and the low milk to 4:1 or below, compared with commercial animal foods (p<0.05). Oleic acid was significantly increased in the low Hanwoo beef, the low chicken, the low egg and the low milk by 11.49, 8.16, 11.25, 2.69 and 24.12%, respectively, compared with commercial animal foods (p<0.05). Compared with the common Hanwoo beef and the low Hanwoo beef, the imported beef showed that the n-6/n-3 ratio was higher by 8.70 and 15.46 times, respectively while oleic acid was significantly decreased by 5.61 and 17.75%, respectively (p<0.05). When commercial animal foods were taken, the blood LDL-C level related with an increase or a decrease of cholesterol was not changed only in the common egg but it was significantly increased in the imported beef, the common Hanwoo beef, the common pork, the common chicken and the common milk by 27,02, 7.85, 25.81, 5.77 and 8.97%, respectively (p<0.05). When low animal foods with lower n-6/n-3 ratio were taken, it was significantly decreased in the low Hanwoo beef, the low pork, the low chicken and the low milk by 22.05, 22.89, 27.55, 12.38 and 14.78%, respectively compared with the imported beef and commercial animal foods (p<0.05).
