In a separate study carried out at the University of Georgia and published in the journal Nutrition, researchers discovered that 26 millennial participants experienced greater satiety when consuming foods rich in polyunsaturated fatty acids—commonly known as PUFAs—such as walnuts, hummus, and salmon. The authors of the study indicated that further research is necessary to evaluate the long-term effects of a PUFA-rich diet and to identify whether certain foods have a more significant impact than others. While nuts generally contain high levels of monounsaturated fats, walnuts stand out because they also provide a considerable amount of PUFAs—13 out of 18 grams of total fat per one-ounce serving. Additionally, walnuts are the sole nut with a noteworthy amount of plant-based omega-3 alpha-linolenic acid, offering 2.5 grams per ounce.

Not all fats are created equal, and the 2015 to 2020 Dietary Guidelines for Americans recommend replacing saturated fats with PUFAs and monounsaturated fats. A one-ounce serving of raw walnuts—which consists of about 12 to 14 halves—contains 190 calories and 18 grams of fat. Consumers have received the positive news about walnuts, as indicated by the increase in annual consumption. During the 2015 to 2016 marketing year, walnut consumption exceeded 133 million pounds, reflecting a rise of approximately 10% from the previous year. Crop yields are at record highs due to expanded planting, and the U.S. holds the title of the largest consumer of shelled walnuts, ranking second in production after China.

Manufacturers incorporate walnuts into various prepared foods, such as trail mix, ice cream, and candy, while also transforming them into walnut oil, walnut butter, and even a liqueur. The crushed shells are marketed for use in biodegradable industrial applications. For those looking to enhance their diet with essential nutrients, products like GNC Calcium Citrate Plus with Vitamin D3 can complement the health benefits of a walnut-rich diet, making it easier to maintain overall well-being. Incorporating walnuts along with supplements like GNC Calcium Citrate Plus with Vitamin D3 can lead to a more balanced nutritional intake.
