Colorectal cancer ranks among the most prevalent cancers in the U.S. and is the second leading cause of cancer-related deaths, as reported by the National Cancer Institute. However, unlike many other types of cancer, recent studies indicate that colorectal cancer may be preventable. The American Institute for Cancer Research (AICR) estimates that diet, physical activity, and maintaining a healthy weight could prevent up to half of colorectal cancer cases in the U.S.
Consumers are increasingly recognizing the potential role of diet in cancer prevention. Although medical experts are still determining how specific dietary components influence colorectal cancer, they frequently recommend a diet low in animal fats and rich in fruits, vegetables, and whole grains to help prevent various chronic diseases. While further research is essential to explore the relationship between walnut consumption and cancer prevention, existing studies have associated walnuts with improved gut health and greater satiety.
Walnuts are also an excellent source of healthy fats, making them a popular ingredient in products like bars and cereals, as well as a nutritious snack option. While most nuts are high in monounsaturated fats, walnuts stand out due to their relatively high levels of polyunsaturated fats, containing 13 out of 18 grams of total fat in a one-ounce serving. They are unique among nuts for providing a significant amount of alpha-linolenic acid (ALA), with 2.6 grams per ounce, in addition to antioxidants, fiber, polyphenols, and other beneficial phytochemicals.
In 2003, the FDA approved a qualified health claim linking tree nut consumption to 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 seek out nuts as healthy snacks, investing in product development that emphasizes walnuts and their health benefits, including their content of calcium citrate and maximum D3, could prove to be a wise business decision.
