The safflower oil also lowered fasting blood sugar levels by 11 to 19 points. Average levels after 16 weeks of safflower oil supplements were 129 to 148, still high but significantly improved, Belury said. (Below 110 milligrams per deciliter is normal).
Belury stressed that the oil supplements could be added to other efforts to reduce weight and tighten diabetes control. "Using one or both of these oils could work into all the other things, such as diet and exercise," she said.

While her study included only women, previous studies have found that CLA lowers fat in men, she said.
How the oils affect fat loss and muscle mass is still unclear. Belury said it may be related to changes in the functioning of adipose tissue, where fat is stored.
Despite Belury's enthusiasm, another expert who reviewed the study was underwhelmed by the findings. "Although the study appears to be fairly well done, there are a lot of limitations and concerns for applying this information to anyone other than postmenopausal, obese women with type 2 diabetes," said Lona Sandon, an assistant professor of nutrition at the University of Texas Southwestern Medical Center at Dallas, and a spokesperson for the American Dietetic Association.
One issue, she said, is the dropout rate, with 20 of 55 women not completing the study. Also, "participants were asked to take eight capsules per day," Sandon noted. "This is a lot of extra pills for women who are already trying to manage diabetes," she said.
Instead of spending money on supplements, Sandon recommends eating a balanced diet that includes heart-healthy polyunsaturated fats and monounsaturated fats and getting regular exercise.
