LYNDEN, Wash. — A simple addition to the plate may help support both metabolic and brain health as we age. New research published in the British Journal of Nutrition found that adding red raspberries to a meal improved post-meal blood sugar responses and enhanced cognitive performance within hours.
Red raspberries are naturally rich in polyphenols, plant compounds known to influence metabolic and inflammatory processes relevant to brain health. To better understand this connection, researchers tested whether adding 25 g of freeze-dried red raspberry powder to a high-carbohydrate, moderate-fat meal could influence post-meal metabolic responses and cognitive performance in adults ages 55 to 70 who are overweight or obese.
After eating the raspberry-containing meal, participants experienced a smaller rise in blood sugar and a lower insulin response compared with the control meal. Blood samples collected after the meal also showed reduced neuroinflammatory responses in laboratory testing, suggesting a potential protective effect on the brain following meals.
Participants also performed better on a standardized battery of cognitive tests within hours of eating the raspberry meal. Researchers observed improvements in learning and memory tasks, including fewer errors and more efficient problem-solving strategies.
Importantly, these benefits were observed after just one meal that included freeze-dried red raspberry powder, highlighting the potential for immediate post-meal effects.
“As we age, maintaining healthy blood sugar and cognitive function becomes increasingly important,” said Britt Burton-Freeman, PhD, MS, Director of the Center for Nutrition Research, Illinois Institute of Technology. “These results show that adding red raspberries into your daily diet may have some metabolic and cognitive benefits that are important to all of us as we age.”
Frozen Washington red raspberries make it easy to enjoy these benefits year-round. Harvested at peak ripeness and frozen within hours to help preserve flavor and nutrients, they can be quickly added to smoothies, oatmeal, sauces and everyday meals. Shoppers can find frozen Washington red raspberries in the freezer aisle by looking for “Product of the USA” on the label.
While longer-term studies are needed, the findings add to growing research showing how everyday dietary choices can help support metabolic and brain health.
ABOUT THE WASHINGTON RED RASPBERRY COMMISSION
The Washington Red Raspberry Commission (WRRC) represents the growers and processors who produce 90% of the American-grown frozen red raspberries. Grown specifically for freezing, Washington red raspberries are picked at peak ripeness and frozen within hours to preserve their bold flavor, vibrant color and natural nutrition. These berries are the product of generations of farming expertise and sustainable practices, crafted for quality, air-chilled for food safety and available year-round. WRRC promotes the taste, health benefits and versatility of frozen Washington red raspberries while sharing the story of the American farmers behind every berry. Learn more at redrazz.org.
After years of below-average production, Washington state frozen raspberry growers reported a bountiful 2025 crop of over 68 million pounds. According to Gavin Willis, Executive Director of the Washington Red Raspberry Commission (WRRC), this is the state’s highest volume since 2018.
Excessively high temperatures led to what Willis calls “a heat dome” during the 2021 and 2022 harvests, which hit the industry hard in both service and plant development. The result was a massive 30 percent dip in production in 2021 compared to 2020, followed by another 23 percent drop in 2022.
The damage was done, and the path back to peak performance was ahead. Patience and plant rotation were key to Washington’s frozen raspberry comeback. The executive explains that today, most of the plantings impacted during the 2021 heat dome are being cycled out of the fields, and those that still remain seem, for the most part, to have healed.
The executive says the year brought good weather through the pollination window and the six to eight-week harvest period. The absence of any persistent cloud cover kept good moisture levels in the field, curbing excess mold and resulting in what Willis calls an excellent yield for the frozen raspberry category.
Washington produces 90 percent of the United States’ frozen raspberries, with 99.8 percent of their crop going to this category.
Mexico is the biggest exporter of fresh raspberries into the country, with a largely unchallenged market share of 72 percent. In the frozen category, Mexico ranks second, behind Chile, with sales of almost $23 million in 2024. But the Aztec country is only diverting five percent of its production to the frozen raspberry category, so the opportunity for growth is ripe for the taking.
Willis explains that Washington frozen raspberries cannot compete with Mexico because, for them, there’s no price floor.
For the past five to seven years, he says, byproducts from the Mexican fresh market (fruit that didn’t make grade or diversions from higher-than-demand production) are being repackaged and folded into the US frozen market. This is significantly affecting the prices Washington growers can aspire to.
“It’s impossible to compete, and for buyers it’s really hard to turn down something that’s basically being offered to you at less than what it costs to produce it,” Willis says. “A lot of these producers or growers are selling this product when they’ve already made their profits in the fresh market, [so] they don’t need to make a profit on it.”
