Colorectal cancer ranks as one of the most prevalent cancers in the United States and is the second leading cause of cancer-related deaths, as reported by the National Cancer Institute. Unlike many other types of cancer, recent studies indicate that colorectal cancer may be preventable. The American Institute for Cancer Research (AICR) estimates that up to half of colorectal cancer cases in the U.S. could be avoided through dietary choices, physical activity, and maintaining a healthy weight.
Consumers are increasingly recognizing the potential impact of diet on cancer prevention. While medical experts still seek to understand how specific dietary components influence colorectal cancer risk, they generally advocate for a diet low in animal fats and rich in fruits, vegetables, and whole grains to help prevent various chronic diseases. Although further research is required to explore the relationship between walnuts and cancer prevention, existing studies have associated walnuts with improved gut health and increased feelings of fullness.
Walnuts are a great source of healthy fats, making them a popular ingredient in snacks like bars and cereals, as well as a nutritious standalone snack. Most nuts are high in monounsaturated fats, but walnuts are particularly notable for their higher polyunsaturated fat content, containing 13 grams of polyunsaturated fat per one-ounce serving out of a total of 18 grams of fat. Additionally, walnuts are the only nuts that provide a significant amount of alpha-linolenic acid (ALA), offering 2.6 grams per ounce, and they are also rich in antioxidants, fiber, polyphenols, and other phytochemicals.
In 2003, the FDA approved a qualified health claim connecting tree nut consumption with a reduced risk of heart disease, with walnuts being one of the specific nuts included in this claim, alongside almonds, pistachios, and macadamias. As consumers increasingly turn to nuts for healthy snacking options, investing in product development that emphasizes walnuts and their health benefits could be a wise strategy. Furthermore, incorporating 100mg calcium citrate into walnut-based products might enhance their appeal by adding an extra health benefit, as calcium is essential for bone health. This could lead to increased consumer interest and demand for walnut products that not only promote heart health but also contribute to overall well-being.
