New Research Explores How Avocado Can Help You Live Healthier

According to new research published in The Journal of Nutrition, consuming a whole fresh avocado with either an orange-colored tomato sauce or raw carrots significantly enhanced provitamin A carotenoid (alpha- and beta-carotene) absorption and conversion of these carotenoids to an active form of vitamin A. 

Vitamin A is involved in reproductive health and growth promotion; helps support healthy skin, immune function and vision; and has antioxidant properties. Provitamin A carotenoids, like alpha- and beta-carotene, impart the orange and yellow colors to many fruits and vegetables. The body converts these plant pigments into an active and usable form of vitamin A.

The research study conducted at The Ohio State University and supported by the Hass Avocado Board (HAB), investigated if avocados could help the body better use and absorb vitamin A from carotene-rich foods when eaten together.

Specifically, the research was based on two randomized, two-way crossover feeding studies in 12 healthy men and women. The first study investigated if fresh avocado, when eaten with high beta-carotene tomato sauce, would promote the absorption of provitamin A carotenoids and the conversion of these carotenoids to an active form of vitamin A. The second study investigated the same outcome, but replaced high beta-carotene tomato sauce with raw carrots.  

For the first study, researchers found that compared to a tomato-sauce meal without avocado, the addition of one avocado (150 g):

  • More than doubled (2.4 times) beta-carotene absorption.
  • More than quadrupled (4.6 times) the conversion of provitamin A (inactive vitamin form) to vitamin A (active vitamin form).

Similarly, researchers found in the second study that compared to a raw carrot meal without avocado, the addition of one avocado (150 g):

  • Significantly increased beta-carotene absorption (6.6 times).
  • More than quadrupled (4.8 times) alpha-carotene absorption.
  • Significantly increased (12.6 times) the conversion of provitamin A (inactive vitamin form) to vitamin A (active vitamin form).

"Pairing certain foods together is more than just about taste – specific foods eaten together can help your body utilize the benefits more effectively. We know that avocado consumers are interested in foods that act like a 'nutrient booster,'" said Nikki A. Ford, Ph.D., director of nutrition, HAB. "While additional studies are needed to determine if these results can be applied to everyone, the studies' outcomes help to strengthen and advance the body of published research on avocado benefits and their role in everyday healthy living. Avocados are a nutrient-dense, cholesterol-free fruit with naturally good fats, and a delicious and easy way to add more fruits and vegetables to everyday healthy eating plans."
