Snacking is widespread, but the measured picture depends on the definition: a self-reported eating occasion, food eaten outside three main meals, or a USDA dietary-recall category. The statistics below separate those measures and identify the population, geography and period behind each result.

How Often Americans Snack and Replace Meals
The 2024 IFIC Food & Health Survey measured self-reported behavior among U.S. adults ages 18–80. It found frequent participation, but the categories describe reported frequency rather than dietary-recall intake.
| Reported 2024 frequency | Share of U.S. adults ages 18–80 |
|---|---|
| Three or more times per day | 14% |
| Twice per day | 31% |
| Once per day | 29% |
| A few days per week | 20% |
| Once a week or less | 5% |
| Never | 2% |
Together, 73% reported snacking at least once daily. The same survey found that 56% said they replace traditional meals by snacking or eating smaller meals, including 16% who did so regularly and 40% who did so occasionally.
Meal replacement varied across generations: the reported rate was 66% for Gen Z, 62% for Millennials, 55% for Gen X and 47% for Baby Boomers. Because this was an online self-report survey, these figures should not be treated as a dietary recall or as directly comparable with NHANES intake estimates. 2024 IFIC Food & Health Survey
Snacking Statistics by Demographic Group
The IFIC survey also shows differences by income, sex and marital status, while NHANES provides a separate one-day recall view by race and ethnicity. These are different measurements and should be read as complementary rather than interchangeable.
- In 2024, meal replacement by snacking was 57% among U.S. adults with household income below $35,000, compared with 53% among those with household income of $75,000 or more.
- The 2024 reported rate was 58% among women and 53% among men.
- It was 58% among single adults and 53% among married adults.
NHANES 2017–March 2020 recorded whether adults ages 20 and older consumed a snack on the dietary-recall day. The observed prevalence was 97% for non-Hispanic White adults, 89% for non-Hispanic Black adults, 92% for non-Hispanic Asian adults and 92% for Hispanic adults.
| Group in NHANES 2017–March 2020 | Snack on recall day |
|---|---|
| Non-Hispanic White adults | 97% |
| Non-Hispanic Black adults | 89% |
| Non-Hispanic Asian adults | 92% |
| Hispanic adults | 92% |
Among men, prevalence was 96% for non-Hispanic White, 88% for non-Hispanic Black, 87% for non-Hispanic Asian and 91% for Hispanic adults. Among women, the corresponding figures were 97%, 90%, 95% and 92%; subgroup differences carry survey uncertainty. Snack Consumption by U.S. Adults, WWEIA/NHANES 2017–March 2020
Snacking Statistics on Calories, Energy and Nutrients
Snacks account for a substantial share of intake in U.S. dietary-recall data. In 2017–March 2020, adult snack consumers obtained 24% of daily energy from snacks on average, while snacks supplied 43% of their daily added-sugar intake.
Earlier national estimates give additional context, but the periods and survey methods differ:
- In 2015–2016, snacks supplied 22% of calories for U.S. adults ages 20 and older.
- In 2015–2016, snacks supplied 23% of calories for U.S. youth ages 2–19.
- In NHANES 2013–2016, 86% of adults reported at least one snack occasion, and snacks contributed 23% of daily energy.
A historical peer-reviewed analysis found that snack contribution to adult energy intake increased from 18% in 1977–1978 to 24% in 2003–2006. Adult snacking prevalence rose from 71% to 97% across those same survey periods, while the study-derived change in occasions was 0.97 snacking events per day.
The historical series spans changing survey instruments and definitions, so it should not be read as a continuous annual trend. The NHANES estimates also use one-day dietary recall, and the included snack definition covers snack, drink and extended-consumption occasions where specified.

Snack Foods, Drinks and Purchase Sources
The 2024 IFIC survey asked U.S. adults ages 18–80 what they considered a typical snack. Response categories may overlap, so the percentages should not be summed.
| Typical snack selected in 2024 | Share |
|---|---|
| Savory or salty snacks | 30% |
| Fruits | 21% |
| Cookies, cake or ice cream | 21% |
| Candy, chocolate or other treats | 19% |
| Nuts, seeds or nut/seed butters | 17% |
| Leftovers from previous meals | 10% |
| Dairy foods such as cheese or yogurt | 10% |
A separate NHANES 2013–2016 study examined where adult snack reporters obtained items. The source categories were not mutually exclusive because a person could report more than one source during the recall period.
- Grocery stores were reported by 86% of adult snack reporters.
- Convenience stores were reported by 20%.
- Someone else or a gift was reported by 19%.
- Quick-service restaurants were reported by 12%.
- Another source category was reported by 8%.
- Full-service restaurants were reported by 4%.
Grocery-store sourcing was 85% for both female and male snack reporters. Convenience-store sourcing was 24% among male reporters and 16% among female reporters.
Among convenience-store snack reporters, 51% obtained a beverage only, 30% obtained food only and 20% obtained both food and a beverage; the published values are rounded. Where Do Adults Obtain Snacks? What We Eat in America, NHANES, 2013–2016 · 2024 IFIC Food & Health Survey
Snacking Motivations, Portions and Timing
The 2024 IFIC survey asked U.S. adults who snack to select their top reasons, so responses can overlap. The results describe perceived motivations rather than measured causes or outcomes.
- Hunger or thirst was cited by 43% of U.S. adults who snack.
- Snacks as a treat were cited by 30%.
- Wanting sweet snacks was cited by 24%.
- Needing energy was cited by 23%.
- Boredom, habit and snack availability or convenience were each cited by 22%.
- Wanting salty snacks was cited by 21%.
- The time until the next meal was cited by 19%.
The same survey found that 11% of Americans who snack said they do so as fuel before or after exercise. In a separate cost-related question, 64% of surveyed U.S. adults ages 18–80 said in 2024 that they had noticed a change in food and beverage costs; this is a perception measure, not a snack-price index.
Together, the findings distinguish physical cues, preferences, routine and convenience. They do not establish that any motivation causes a particular calorie, nutrient or health outcome. 2024 IFIC Food & Health Survey
Long-Term Snacking Trends and Mexico Comparison
Long-term U.S. comparisons indicate that snacking became more common and contributed more energy across the historical periods studied. However, the 1977–1978, 2003–2006, 2013–2016, 2015–2016 and 2017–March 2020 estimates come from different survey designs and should not be treated as a single uninterrupted series.
Mexico provides a cross-country comparison with a different operational definition. In Mexico’s 2012 national survey, a snack meant eating outside the three main meals, and 73% of people ages 2 and older consumed snacks on a given day.
| Mexico 2012 age group | Daily snack prevalence |
|---|---|
| Ages 2–11 | 77% |
| Ages 59 and older | 70% |
| All people ages 2+ | 73% |
The Mexico study analyzed 9,937 children and adults across the 1999 and 2012 national nutrition surveys. Its age-group range was 70% among people ages 59 and older to 77% among children ages 2–11, and it should not be interpreted as a direct U.S. trend because the cultural and operational definitions differ.
