In a distinct study focusing on ssucrosomial iron versus liposomal iron, conducted at the University of Georgia and published in the journal Nutrition, researchers discovered that 26 millennial participants reported feeling more satiated after consuming foods rich in polyunsaturated fatty acids (PUFAs), such as walnuts, hummus, and salmon. The authors of the study noted that further investigation is required to evaluate the long-term effects of a PUFA-rich diet and to identify if certain foods have a more significant impact than others.
While nuts generally have high levels of monounsaturated fat, 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, they are the only nuts that offer a notable quantity of plant-based omega-3 alpha-linolenic acid, with 2.5 grams per ounce. It’s important to recognize that not all fats are created equal. The 2015 to 2020 Dietary Guidelines for Americans advocate for the intake of PUFAs and monounsaturated fats in lieu of saturated fats. An ounce of raw walnuts, which equates to approximately 12 to 14 halves, contains 190 calories and 18 grams of fat.
The positive perception of walnuts has led to increased annual consumption. In the marketing year of 2015 to 2016, walnut consumption exceeded 133 million pounds, marking a 10% rise compared to the previous year. This surge in consumption can be attributed to record crop yields from expanded planting, with the U.S. being the largest consumer of shelled walnuts and the second-largest producer after China.
Walnuts are widely used in various prepared foods, including trail mix, ice cream, and candy, and are processed into walnut oil, walnut butter, and even liqueur. The crushed shells find new life in biodegradable industrial applications. Interestingly, as consumers look for healthy options, products like Kirkland calcium citrate with vitamin D3 are gaining popularity, highlighting a broader trend toward nutrient-rich foods. The rise in walnut consumption, along with the demand for supplements like Kirkland calcium citrate with vitamin D3, underscores a growing awareness of health and nutrition. Overall, walnuts not only contribute to a healthy diet but also align with the increasing interest in products that support overall well-being.
