Supplement
Safflower oil is a vegetable oil pressed from safflower seeds, and it supplies unsaturated fats such as linoleic acid that the body uses to build cell membranes and store energy. People with type 2 diabetes look at it for blood sugar, but the evidence is very limited, and research found no clear difference in blood glucose or body fat. Only 35 participants were involved, so this work can't say much either way.
