The California Walnut Commission says walnuts now meet the updated definition for a healthy food, according to the Food and Drug Administration’s updated definition for foods that can be identified or labeled as healthy.
The commission called the move a significant step toward ensuring food labeling is consistent with the most up-to-date nutrition scientific evidence and Dietary Guidelines for Americans recommendations.
The 2020-2025 Dietary Guidelines for Americans encourages consumers to choose nutrient-dense foods, such as walnuts. The commission said close to two-thirds of Americans do not meet the recommended intake for nuts and seeds.
“The inclusion of walnuts in the new ‘healthy’ definition affirms consumers’ belief that walnuts are a healthy food. It also aligns with decades of nutrition research reinforcing the important contributions walnuts can make in a healthy lifestyle,” California Walnut Commission CEO Robert Verloop said in a news release. “It’s simple. Just adding walnuts to Americans’ daily diet can potentially have wide-ranging positive impacts.”
Substituting walnuts for food choices higher in saturated fats can help support Dietary Guidelines for Americans recommendations to replace consumption of saturated fats with unsaturated fats, the commission said.
The total fat in walnuts (18 grams) is mostly composed of polyunsaturated fats (13 grams per ounce), including omega-3 ALA (2.5 grams per ounce), an essential fatty acid with the potential to support heart health and cognition, according to the release. Walnuts are the only tree nut to provide an excellent source of omega-3 ALA.
“In my 20-plus years of practicing nutrition at a major medical institution, I have seen trends go in and out for what the public considers healthy,” said Kristin Kirkpatrick, registered dietitian nutritionist. “But what has always been foundational is the role plant-based foods like walnuts play in supporting health. Walnuts are one nut I find consistently meets the variable needs of patients in my practice. In practice, I focus on evidence-based approaches to reducing chronic disease risk, weight management, and improvements in metabolic health.”
