Americans are increasingly prioritizing protein, but they still want meals that are affordable and convenient. For restaurants, balancing those preferences could make health-focused menu additions more appealing.
An October 7 survey from the International Food Information Council (IFIC) found that 64% of US adults followed a specific eating pattern or diet in the past year, the highest share since tracking began in 2018. High-protein diets led at 27%, up from 23% in 2025.
The findings arrive as restaurant operators face persistent food and labor costs. Adding protein-rich dishes, fiber-forward options, or wellness beverages could appeal to changing preferences, provided customers see enough value to order them.
Protein and fiber lead functional food interest
Functional foods are commonly marketed for nutritional benefits beyond basic nourishment, including protein-rich meals, fiber-forward dishes, and fermented ingredients.
A separate survey of more than 900 US consumers from Revenue Management Solutions (RMS) found that 62% at least sometimes looked for high-protein restaurant options, compared with 45% for high-fiber choices.
Gut health is also attracting attention. An August IFIC survey found that 64% of Americans considered it a high priority, although only 13% reported using specialized functional foods or beverages to support it in the previous year.
Restaurants could respond by highlighting existing dishes featuring beans, lentils, chicken, or whole grains before investing in entirely new menu categories.
Convenience and price compete with health goals
IFIC's October findings revealed a notable shift: convenience overtook healthfulness as a food-purchase consideration for the first time in the survey's 21-year history.
Convenience influenced 61% of respondents, ahead of healthfulness at 56%. Taste remained the leading factor at 88%, followed by price at 78%.
Restaurant-specific findings show another limitation. In the RMS survey, 38% of respondents said they would pay more for high-protein meals, compared with 25% for high-fiber options.
A higher-priced specialty dish may therefore face resistance even among health-conscious diners. Familiar ingredients, reasonable portions, and straightforward preparation could make nutritional options easier to sell without placing additional pressure on menu prices.
Health-focused menus still need to make money
Restaurant margins leave limited room for experiments that fail to attract repeat customers.
The National Restaurant Association reported that 33% of surveyed operators said their restaurants were unprofitable during the first half of 2026.
Before adding specialty ingredients, managers should review food cost percentages, portion sizes, preparation requirements, and supplier availability. Even a popular dish can prove expensive if it increases waste or slows kitchen service.
Existing ingredients may offer a less disruptive starting point. A café could test a Greek yogurt breakfast option, while a fast-casual restaurant might offer beans or whole grains as additions to existing bowls.
How restaurants can test functional food demand
Limited-time offers allow operators to assess interest before committing to permanent menu changes.
Four questions can guide those decisions:
- Demand: Are guests already ordering similar dishes?
- Pricing: Is the proposed price competitive with existing options?
- Operations: Can staff prepare the item without slowing service?
- Profitability: Does the contribution margin justify keeping it?
POS reports can track purchases, average checks, repeat orders, and modifications. The Restaurant HQ's menu engineering guide explains how operators can evaluate popularity alongside profitability and kitchen efficiency.
Menu descriptions also deserve care. Listing ingredients accurately is more defensible than making unsubstantiated claims about digestive health or other medical benefits.
What the 2026 findings mean for restaurant menus
Protein and fiber are attracting consumer interest, but affordability, convenience, and taste remain major influences on food purchases.
Restaurants can begin with familiar dishes, test nutritional add-ons, and adjust offerings using actual sales and operating data. Similar menu-testing considerations appear in The Restaurant HQ's recent comfort-food trends coverage.
For operators, the opportunity is to offer foods that meet changing preferences without sacrificing the qualities that bring customers back: good taste, fair prices, and reliable service.
