Dairy, Meat, Seafood, and Plant Sources of Saturated Fat: United States, Ages Two Years and Over, 2017-2020.

Background: Research suggests that the effects of saturated fat (SF) on health differ depending on its food source. Dairy SF has been associated with lower cardiovascular disease (CVD) risk, whereas meat SF is linked to a higher CVD risk.

Objectives: To estimate the contribution to the total intake of SF of 1) 5 food groups - dairy, meats, seafood, plants, and "other," and 2) the top 10 specific food category sources in the United States population overall and by sociodemographic subgroup.

Methods: The analysis included data from 11,798 participants in the 2017-March 2020 National Health and Nutrition Examination Survey aged 2+ y. Grams of SF from the food sources expressed as a percentage of the total grams of SF consumed, were estimated using the population ratio method.

Results: Mean daily intake of SF was 28.1 g [95% confidence interval (CI): 27.6-28.6 g], comprising 11.9% (95% CI: 11.7-12.1%) of total energy intake. Dairy contributed 28.4% of SF, followed by meats (22.1%), plant sources (7.5%), fish and seafood (1.2%), and the remaining foods (41.6%). Youth had higher SF intake from dairy than adults (P < 0.001), whereas non-Hispanic Whites had higher intake than non-Hispanic Blacks (P < 0.001) and Hispanics (P = 0.016). Adults had higher SF intake from meats than youth (P = 0.002), males more than females (P < 0.001), and non-Hispanic Blacks more than non-Hispanic Asians (P = 0.016) and Hispanics (P < 0.001). The top 10 specific sources of SF were unprocessed red meats, sweet bakery products, cured meats, milk, cheese, pizza, unprocessed poultry, Mexican mixed dishes, eggs, and combined fruits and vegetables.

Conclusions: Although dairy contributed ∼30% of SF compared to ∼20% for total meat, the top specific food category source of SF was unprocessed red meats, which ranked in the top 2 food category sources of SF for most subgroups. These findings may be useful for further research to examine the relationship between the different sources of SF and health outcomes.
