Trends in the consumption of ultra-processed foods among US youth aged 2-19 years, 1999-2018.

Wang L, Martinez Steele E, Du M, et al. Trends in the consumption of ultra-processed foods among US youth aged 2-19 years from 1999 to 2018. Jama. 2021; 326(6): 519-530. doi: 10.1001 / jama.2021.10238

Commentary

In the United States, where childhood obesity rates are rising, increasing evidence links consumption of ultra-processed foods to excessive calorie consumption and weight gain, but trends in ultra-processed food consumption among US youth have not been well characterized.

This study was conducted to characterize the trends in ultra-processed food consumption among U.S. youth.

A nationally representative sample of U.S. youth aged 2-19 years (n = 33 795) from 10 cycles of the National Health and Nutrition Examination Survey (NHANES) and a continuous cross-sectional analysis using 24-hour dietary recall data were used.

As a result, we analyzed dietary intake from youth and found that from 1999-2018, the estimated percentage of total energy from consumption of ultra-processed foods increased from 61.4% to 67.0%.

The percentage of total energy from the consumption of unprocessed and minimally processed foods decreased from 28.8% to 23.5%.

Among the subgroups, the estimated percentage of energy from consumption of ready-to-eat, mixed dishes increased from 2.2% to 11.2%. The consumption of sweets increased from 10.7% to 12.9%, and the estimated percentage of energy from sugar-sweetened beverages decreased from 10.8% to 5.3%.

For processed oils, fats, condiments, and sauces, the estimated percentage of energy from consumption of ultra-processed foods decreased from 7.1 percent to 4.0 percent, and the estimated percentage of energy from consumption of ultra-processed foods increased substantially among non-Hispanic black youth and Mexican Americans.

These results indicate that the estimated percentage of energy intake from consumption of ultra-processed foods is increasing, suggesting that they account for the majority of total energy intake.
