The study concluded: “Study findings that walnut and other nut consumption was associated with better cardiovascular disease risk factors and diet quality aligns with the 2020–2025 US Dietary Guidelines for Americans (DGA) recommendation to consume nuts, such as walnuts, within the context of a healthy diet.
“Our study findings support the health claim to include walnuts as part of a healthy diet by adding the observation of a more favourable risk profile after 30 years of follow-up, a duration that cannot be addressed in randomised control test designs.
“In addition, our findings are consistent with and add a long-term dimension to the 2020–25 DGA to consume a variety of protein sources, including nuts in a healthy eating pattern, and to replace saturated fat with other fats, including those from nuts and olive oil.”
