The rising incidence of metabolic syndrome globally has been attributed to sedentary lifestyles and the consumption of high energy diets with a low omega-3: omega-6 fatty acid ratio. Coriander seeds, commonly used for culinary purposes, have beneficial health effects. We investigated the effects of dietary supplementation with coriander seeds on growth performance, hepatic and visceral adipose tissue lipid storage and circulating metabolic substrates in healthy, growing rats. Female Sprague Dawley rats (150-200 g) were fed either standard rat chow (n = 8) or standard rat chow supplemented with crushed coriander seeds (n = 8; 500 mg per kg body mass). After five weeks, there were no significant differences in body mass gain, plasma free fatty acids and triglyceride concentrations of the rats (p greater than 0.05; t-test). Whilst dietary supplementation with coriander did not affect the lipid content of the liver, it significantly increased the amount of monounsaturated (22.62 plus minus 6.48% vs 0.65 plus minus 0.32%) and polyunsaturated (54.89 plus minus 5.10% vs 22.16 plus minus 7.79%) fatty acids in the visceral adipose tissue where it also decreased the saturated fatty acid content (p less than 0.05; t-test). Coriander increased the omega 3: omega 6 ratio in the visceral adipose tissue which may explain its health benefits.
