• alpha-linolenic acid
• Eruca sativa
• naturally grown vegetables
• n-6/n-3 ratio

The ratio of dietary n-6/n-3 polyunsaturated fatty acids is higher in the modern Western meal when compared with that of the Paleolithic era. Evidences have been accumulating that the extremely high ratio of dietary n-6/n-3 polyunsaturated fatty acids increases the risk of disease and the deterioration of physical conditions among humans. In this study, the ratio of linoleic acid (C18:2, n-6) and a-linolenic acid (C18:3, n-3) of rucola, Eruca sativa, was compared between naturally grown samples and conventional farming products (n= 3 for each). We found that the naturally grown rucola contained significantly higher amount of a-linolenic acid (p= 0.026), resulting in the lower ratio of linoleic acid and a-linolenic acid than the conventional (p= 0.016). This finding suggests that vegetables cultured in conventional farming method could decrease the health promotion effects that the vegetables originally possess in natural environment.
