α-Tocopherol-supplemented diets (modified AIN-93G Purified Rodent Diet with corn oil replacing soybean oil)

	g/kg diet
Casein, high nitrogen	200
l-Cystine	3
Sucrose	100
Cornstarch	397
Dyetrose	132
Corn oil	70
Cellulose	50
Mineral mix no. 210025	35
Vitamin mix no. 210025	10
Choline bitartrate	2.5
d-α-tocopherol	0.5, 0.25, or 0.15

The α-tocopherol-supplemented diet (500 mg/kg diet no. 103296, 250 mg/kg diet no. 103373, or 150 mg/kg diet no. 103372) and the basal control diet without supplementation (45 mg α-tocopherol/kg diet) (diet no. 101591) were from Dyets. Corn oil, which was commonly used in rodent diet in the past, was used in this diet instead of the more recent formulas with soybean oil to avoid the proinflammatory contribution of high γ-tocopherol in soybean oil as we have reported (5, 17, 44).
