The study found that a single 51-mg dose of beta-carotene given in the absence of dietary fat resulted in no detectable change in serum beta-carotene. The same dose administered with 200 g fat increased serum beta-carotene 2.5-fold at 40 hours.

The author concluded that: "the data indicated that beta-carotene absorption requires dietary fat and is enhanced by administering with meals".
