At Pioneer we are generational walnut growers with roots in the industry dating back to the Late 1980s. We take pride growing high quality product starting from the field.


In the winter months we hand prune our Walnut trees to give the trees proper structure.  Starting In Spring and through summer we care for the orchards by irrigating, fertilizing and protecting from pests. Our goal is care for the nuts to ensure the highest quality product for you!


After harvesting the crop we process the Walnuts in our State-of-the-art plant in Chico, CA. From this plant we are able to supply both Inshell and Shelled Walnuts in all grades and sizes.


Thank You for your interest. Please let us know how we can help you!


Extensive research conducted over the years has yielded compelling evidence suggesting that walnuts offer a multitude of potential health benefits. These remarkable nuts have shown promising effects in mitigating the risk of various diseases, including diabetes, cancer, microbiome imbalances, and metabolic disorders.

Numerous studies have highlighted the positive impact of walnuts on diabetes prevention and management. The nutrients and bioactive compounds present in walnuts contribute to improved glycemic control and insulin sensitivity, potentially reducing the risk of developing diabetes or helping individuals with diabetes better manage their condition.

Furthermore, emerging research has shed light on the potential anti-cancer properties of walnuts. The unique blend of antioxidants, polyphenols, and omega-3 fatty acids found in walnuts may exert protective effects against certain types of cancers, such as breast and prostate cancer. These compounds have shown promise in inhibiting tumor growth, preventing angiogenesis (the formation of new blood vessels that support tumor growth), and promoting cancer cell death.

In addition to their impact on diabetes and cancer, walnuts have been linked to positive effects on the microbiome and metabolic disorders. The microbiome, the complex community of microorganisms living in our gut, plays a crucial role in overall health. Consuming walnuts has been associated with favorable changes in gut microbiota composition, supporting a healthy balance of beneficial bacteria. Moreover, the nutrient profile of walnuts, including their high levels of unsaturated fats, fiber, and plant sterols, may contribute to improved lipid profiles and reduced risk of metabolic disorders like obesity and cardiovascular disease.

While further research is needed to fully understand the mechanisms behind these potential health benefits, the existing evidence suggests that incorporating walnuts into a balanced diet may have a positive impact on overall health and disease prevention. So why not enjoy the delicious taste and reap the potential rewards by including walnuts in your daily meals and snacks?
