Each survey’s methodology is briefly described below:July 2025 IFIC Spotlight SurveyIFIC commissioned this online survey among U.S. consumers (n=1000) to measure knowledge, attitudes, and beliefs about protein. One thousand adults ages 18 years and older completed the online survey from May 10-13, 2025, and were weighted to ensure proportional results. Totals may not equal 100% due to rounding.

July 2025.2025 IFIC Food & Health SurveyIFIC commissions this survey annually among U.S. consumers (n=3000 since 2024, n=1000 in prior years), with 2025 marking the 20th consecutive year of the IFIC Food & Health Survey. Results were weighted to ensure that they are reflective of the American population ages 18 to 80 years, as seen in the 2024 Current Population Survey. Specifically, results were weighted by age, education, gender, race/ethnicity, and region. The 2025 IFIC Food & Health Survey was fielded from March 13-27, 2025.SUGGESTED CITATION: International Food Information Council (IFIC). 2025 IFIC Food & Health Survey.METHODOLOGY© 2024 International Food Information CouncilAccording to the annual IFIC Food & Health Survey, the percentage of Americans trying to consume protein is on the rise: In 2022, 59% said they try to consume protein, 67% in 2023, 71% in 2024, and 70% in 2025.

In parallel, some nutrition researchers are both questioning and further investigating protein recommendations to support optimal health outcomes. In the same spirt, IFIC commissioned the IFIC Spotlight Survey: Americans' Perceptions Of Protein to study U.S. consumer mindsets related to protein sources and consumption.In this IFIC Spotlight Survey, 35% of respondents report they have increased their protein consumption in the last year. However, when asked about how much protein they should consume daily, most respondents indicated they are unaware (53%) or unsure (26%) of their daily protein needs. Of the 20% of respondents who report to know how much protein they should consume, over half (54%) think it should be 50 grams or less per day.When asked about perceived health benefi
