Individual fasting glucose values are depicted for 30 healthy men and women at study entry and after 4 wk on diets rich in test fats of POL, PHSO, and IE. Participants consumed complete, whole-food diets for 4-wk periods in a crossover study design. Total fat comprised ∼31% daily energy (>70% from the test fats). Compared with entry values of glucose, increases of 3%, 9%, and 22% were seen after consuming the diets rich in POL, PHSO, and IE, respectively. IE, interesterified fat based on fully hydrogenated soybean oil; PHSO, partially hydrogenated soybean oil; POL, palm olein. Reproduced from reference 1 with permission.
