Camelina sativa is a novel plant source of alpha‐linolenic acid (ALA) with a similar fatty acid profile to flaxseed. A double‐blind parallel‐arm pilot study investigated the lipid lowering effects of daily consumption of camelina sativa oil for 6 weeks. Twenty overweight women (mean ± SD; 28.0 ± 2.6 kg/m 2 ) were randomized to one of two groups: 2T/d camelina oil (CO)(8g ALA/d) (n=10) or 2T/d sunflower oil (SO)(0g ALA/d)(n=10). Subjects consumed an ad libitum diet; test foods provided as baked goods. Weight significantly increased over time for both groups (CO: 70.8 ± 4.9 kg vs. 75.3 ± 7.8 kg; SO: 77.2 ± 10.2 kg vs. 79.4 ± 10.7 kg)(P<0.05). A significant decrease for total cholesterol (TC) (CO: 4.5%; SO: 7.8%) and high‐density lipoprotein (HDL) (CO: 22%; SO: 18%) was observed for both groups (P<0.05). A decrease (SO: 3.3%; P>0.05) in plasma low‐density lipoprotein (LDL) was found whereas an increase of 7% (p>0.05) occurred for the CO group. Results suggest that changes in the lipid profile are attainable with a plant‐based polyunsaturated fatty acid despite significant weight gain. The safflower oil was more effective at producing positive lipid changes than the camelina sativa oil. Future research is warranted with more controlled feeding interventions to minimize weight gain.
