Daily strawberry consumption was linked to improved cognitive function, lower blood pressure and higher antioxidant capacity in a randomized clinical trial presented at Nutrition 2023, the annual meeting of the American Society of Nutrition (ASN).
The study, conducted at San Diego State University, builds on previous research demonstrating the cardiovascular, metabolic and cognitive health benefits of strawberries.
The double-blind, placebo-controlled study was conducted in 35 healthy men and women, aged 66 to 78. Participants consumed 26 grams of freeze-dried strawberry powder, equivalent to two servings of strawberries daily, or a control powder for eight weeks each.
Following strawberry consumption, cognitive processing speed increased by 5.2%, systolic blood pressure decreased by 3.6% and total antioxidant capacity significantly increased by 10.2%. Waist circumference decreased by 1.1% during both the control and intervention arms of the trial. While consuming the control powder, participants experienced increased serum triglycerides.
“This study demonstrates that consuming strawberries may promote cognitive function and improve cardiovascular risk factors like hypertension,” said Shirin Hooshmand, professor in the School of Exercise and Nutrition Sciences at San Diego State and principal investigator on the study. “We’re encouraged that a simple dietary change, like adding strawberries to the daily diet, may improve these outcomes in older adults.”
Strawberries are a source of many bioactive compounds. In addition to providing 100% of our daily vitamin C needs, strawberries contain heart-healthy nutrients like folate, potassium, fiber, phytosterols and polyphenols.
Previous clinical trials have connected strawberry consumption to improvements in several markers for cardiovascular disease, including reduced total and LDL cholesterol (TC) and lower blood pressure.
The link between strawberry consumption and brain health has also been well explored in both clinical and population-based studies. Strawberries and pelargonidin, a biochemical primarily found in strawberries, were associated with a reduced risk of Alzheimer’s dementia in studies conducted at Rush University. Long-term observational studies, including the Health Professionals Study and the Nurses’ Health Study, found that strawberry consumers had lower rates of cognitive decline.
USDA data shows strawberry consumption continues to surge.
Retail per capita availability of strawberries has grown from 5.3 pounds in 2016 to 6.7 pounds in 2021, according to the USDA.
Both domestic and import supplies of strawberries have increased in the past two decades, but the growth of imports has been much stronger.
The USDA estimates that domestic strawberry output increased from 1.77 billion pounds in 2016 to 2.17 billion pounds in 2021, a gain of 23% in that five-year period.
At the same time, imports of strawberries increased 43% from 2016 to 2021, rising from 365 million pounds in 2016 to 521 million pounds in 2021.
As a percent of the total strawberry supply in the U.S., the USDA reports that imports accounted for 19% of the total supply in 2021, up from 17% in 2016 and up from just 7% in 2000.
The peak month for domestic strawberry availability in 2022 was May, when shipments accounted for 15% of the total annual supply. Other top months for strawberry shipments include June (14%), April (11%), July (11%) and March (9%). The month with the smallest domestic shipments in 2022 was December, when just 3% of the domestic annual volume was shipped, according to USDA truck shipment data for conventional fruit.
Imported strawberry volume, dominated by Mexico, is active year-round. However, the top months for strawberry imports were February (18% of total annual volume), March (18%), January (16%) and April (14%). The smallest import volumes were recorded in August and September, which both accounted for less than 1% of the total imported annual volume.
Strawberries enjoy one of the highest household penetration levels in the U.S. among fresh fruits, and the highest per capita consumption in the berry patch, both in fresh and frozen markets.
In the latest RaboResearch Report, it highlights that as demand continues to grow steadily, planted area in California is expanding. Record shipments are likely in 2023, but weather remains the usual wildcard, particularly this season, as growing areas in California have been impacted by record rainfall.
While the fresh market remains mainly a regional North American story, U.S. imports of frozen strawberries from South America are changing the landscape. With the availability and consumption of all berries expanding, interesting market opportunities arise.
Per-capita availability of U.S. fresh blueberries and raspberries at the retail level has more than doubled in the past decade, according to USDA data.
From 2010 to 2019, per-capita availability of blueberries at retail has grown from 1 pound to 2.1 pounds, a twofold-plus gain. During the same period, per-capita retail availability of raspberries has also more than doubled, from 0.3 pounds in 2010 to 0.80 pounds in 2019.
Strawberries still represent the most widely consumed fresh berry, with the USDA reporting 5.3 pounds retail per capita in 2019.
However, that number is down about 19% from 6.6 pounds in 2010, the USDA said.
Per-capita consumption of blueberries from 2010 to 2019, in pounds, was:
- 2010: 1.0;

- 2019: 2.1.
Per-capita consumption of fresh raspberries from 2010 to 2019, in pounds, was:
- 2010: 0.2;
- 2011: 0.3;
- 2012: 0.3;
- 2013: 0.3;
