Dietary meats play a crucial role in human health.The objective of this survey was to determine the fatty acid content and omega-6/omega-3 polyunsaturated fatty acids(n-6/n-3 PUFA)ratio of fresh red meat(beef and pork)from four cities(Shanghai,Nanjing,Yinchuan and Hohhot)in China.The results showed that the n-6/n-3 PUFA ratio from all the samples ranged from 6 to 23.The total n-6 PUFA concentrations ranged from 290.54 mg/100g in beef from Nanjing to 1601.48 mg/100 g in pork from Hohhot,whereas the total concentrations of n-3 PUFA ranged from 46.34 mg/100 g in beef from Nanjing to 96.03 mg/100 g in pork from Nanjing.The results indicated that the n-6/n-3 ratio in the red meat from all four regions is unbalanced and is much higher than that(<5:1)recommended by the WHO/FAO.The total amount of n-3 PUFA was far lower than the required daily dose.Therefore,potential solutions to increase the n-3 PUFA content in meat products or to provide alternative source of n-3PUFA should be explored.

PUFA was far lower than the required daily dose. Beforefore, potential solutions to increase the n-3 PUFA content in meat products or to provide alternative source of n-3 PUFA should be explored.
