Americans know plant-based diets are good, but still really like meat

While a majority of Americans acknowledge the health and environmental benefits of eating more plant-rich diets, only about a quarter are willing to adopt them.

That’s just one of the key findings of a recent study that reveals that Americans’ beliefs about the value of eating more plants for health and environmental reasons are often at odds with their dietary choices.

“US consumers have favorable perceptions of foods and beverages that support human and environmental health, but that’s not translating into what they’re purchasing and consuming,” says the study’s lead researcher, Katherine Consavage Stanley, a PhD student in the human nutrition, foods, and exercise department at Virginia Tech.

For the study, published in the journal Nutrients, the researchers pored over a decade of national survey responses, gathered from 2012-22 by the International Food Information Council, to examine American’s dietary patterns and practices. They statistically analyzed more than 1,000 respondents’ perceptions, beliefs, and behaviors regarding plant-rich dietary practices for each year of the study and how they related to human health, environmental, social, and economic impacts.

Plant-rich diets can range from vegan and vegetarian, which avoid meat consumption, to flexitarian and Mediterranean diets, which can include small amounts of meat and fish along with plant-based foods. The World Health Organization and the United Nations’ Food and Agriculture Organization encourage these types of diets as eating patterns that promote human health, have low climate impact, and are affordable for feeding a growing world population.

The study’s findings included the following:

Plants are widely perceived as healthier, but Americans’ love their meat.

• Across all years surveyed, 73% of Americans said plant proteins were healthy; 39% said animal proteins were healthy.
• An average of 4.6% of consumers said they followed vegetarian or vegan diets.
• The percentage of Americans that reported following a plant-rich dietary pattern more than doubled across the years surveyed, from 12.1% to 25.8% by 2019-22.
• Younger consumers—Generation Z, born 1997-2012, and millennials, born 1981-96—were more likely to follow a plant-rich pattern than older consumers—Generation X, born 1965-80; baby boomers, born 1946-64; and the silent generation, born 1928-45—in all years surveyed.
• From 2020-22, the percentage of respondents who reported eating more red meat increased from 13% to 19%.
• About one-quarter of Generation Z and millennials also reported increased red meat consumption in the past year, red 10% of older adults.

Over a 10-year period, a declining percentage of Americans identified “healthfulness” as important in their food purchasing choices.

Eating foods identified as “sustainable” is important—but not enough to pay for it.

• In 2016, 75% of respondents said it was “somewhat or very important” to purchase and consume “sustainably produced products,” but this decreased to about half of respondents identifying this as important in future years surveyed.
• On average, 32% of consumers said “environmental sustainability” was a substantive factor in their purchase decisions.
• Sustainability was consistently ranked as the least important factor in Americans’ food and beverage purchase decisions, following convenience, price, healthfulness, and taste.
• Less than one-quarter of respondents indicated that they purposefully purchased foods labeled as organic (27%), locally sourced (26 %), environmentally-friendly (21%), or plant-based (16%).

More information is needed.

• Nearly two-thirds of respondents felt it was challenging for consumers to know what impact their food and beverage choices might have on the environment.
• Similarly, most respondents said that if it was easier to access information about the environmental impact of foods and beverages, it would have a greater influence on their choices.
• The findings reveal a need for government leaders, health and nutrition professionals, and the food and beverage industry itself to provide more information on the sustainability of food products.

“We can’t expect consumers to make sustainable choices if they don’t know the impacts of their purchases,” Stanley says. “We need to be doing more collectively to educate Americans on the benefits of plant-rich dietary patterns and to provide an environment where making healthy and sustainable purchases is the default choice.”

In a follow-up study, Stanley is examining the landscape of US media campaigns that encourage or discourage plant-rich dietary patterns and practices.

“Too often corporations will place the responsibility on individuals, but Americans need a supportive food and beverage environment to make changes,” she says.
