Health Benefits Raising Walnut Interest

As shoppers continue to seek foods that offer health and wellness benefits, there is a growing body of health research sparking interest in walnuts, offering the opportunity for retailers to increase walnut sales with health-conscious shoppers. Coupled with mounting interest in whole, natural foods — as emphasized in the recent Dietary Guidelines for Americans — walnuts are poised to show up in more shoppers’ baskets in the year ahead.

Seventy-nine percent of shoppers report that walnuts’ health benefits positively impact their purchase decisions, presenting a clear opportunity for retailers to highlight health benefits and attract shoppers through merchandising, education, and strategic product placement.

With more than 200 peer-reviewed studies examining how walnut consumption supports human health, walnuts can play a meaningful role throughout the lifespan, supporting essential areas, such as heart health, cognition, cancer, diabetes, metabolic syndrome, gut health, body weight/composition, reproductive health, sleep and more.

Retailers can effectively promote walnut health benefits to shoppers through various health-focused strategies — including retail registered dietitians and other shopper education initiatives — to instill confidence in the category and drive demand.

WALNUT NUTRITION AND RESEARCH AREAS

Walnuts are the only nut to contain a significant amount of the plant-based omega-3 alpha-linolenic acid (ALA) (2.5 grams per ounce), an essential fatty acid that may play a role in heart health, brain health and inflammation.

A one-ounce serving of walnuts also offers 4 grams of protein, 2 grams of fiber and a good source of magnesium (10% Daily Value). That same serving contains 18 grams of healthy fats, including 2.5 grams of monounsaturated fat and 13 grams of polyunsaturated fat, as well as 1.5 grams of saturated fat.

Ongoing research across life stages ranging from in utero, teen years and into older adulthood shows walnuts’ unique nutrition benefits offer something for everyone. Established and emerging research areas for walnuts include:

• Cardiovascular Health: More than three decades of research and 65 publications demonstrate a positive link between walnut consumption and heart health across numerous health measures in adulthood and older adulthood. Additionally, walnuts are certified by the American Heart Association (AHA) with the Heart-Check mark, per one-ounce serving.

• Weight Management: A growing body of research has explored how walnuts may help reduce the risk of chronic disease and be beneficial for overall health and weight management by supporting satiety and satisfaction. Walnuts offer nutrients like fiber (2 grams per ounce) that help you feel full and satisfied, which can play a role in how much you eat and promote weight management.

• Brain Health and Cognition: Scientific research continues to investigate how including walnuts, as part of a healthy diet, may play a role in helping to maintain and improve brain health and overall well-being as people age.

• Gut Health: Emerging research in adults is examining how walnuts may support gut health due to their prebiotic potential and possible role in positively influencing the gut microbiome.

• Mental Well-Being: New and ongoing research is delving into how certain nutrients included in walnuts could play a supporting role in mental well-being, including depression, mood and sleep, in teens through older adulthood. Walnuts contain melatonin (3.5 +/- 1.0 ng/g), an important hormone related to maintaining a healthy sleep cycle.

COMMUNICATING HEALTH AND WELLNESS BENEFITS AT RETAIL

Displaying walnuts prominently in high-traffic locations like the produce aisle, and ideally placed adjacent to complementary foods, such as berries, bagged salads, hot cereals and yogurt, is recommended. Use signage on displays to remind shoppers of California walnuts’ unique taste and texture, their versatility and their nutritional benefits, including being the only nut with an excellent source of omega-3 ALA (2.5 grams per ounce).

The ALA content in walnuts makes them more sensitive to heat and oxygen, so for optimum quality, it is important for consumers to store any walnuts they are not going to use right away in an airtight container and keep in a refrigerator or freezer. Use signage and social media to educate shoppers on the importance of properly storing their purchases once home to ensure greater satisfaction and repeat purchases.

AHA’s Heart-Check mark is also an effective tool for reinforcing walnuts’ heart-health benefits at retail. The California Walnut Board can support promotional efforts with tools, such as header cards, shelf signs, and even recipe cards that include the Heart-Check mark to spark added sales.

The California walnut industry is leaning into health and wellness as part of its new “Feel Good” effort, which aims to bring modern relevancy to walnuts for younger consumers by moving beyond traditional commodity marketing. Instead, it positions California walnuts as a lifestyle brand with a fresh, energetic visual identity carried across the full shopper journey, from discovery to purchase. This repositioning speaks to shoppers who value both nutrition and versatility and want their food choices to match their lifestyle.
