Cashew beyond trade, a powerhouse of nutrients and new business opportunities
Cashew nut has carved a global niche well beyond its role as a cash crop. Its nutritional benefits, culinary versatility and potential for value addition are creating new opportunities for farmers, processors and entrepreneurs.
Cashew’s nutritional profile
Cashews are nutrient-dense. They provide healthy fats, plant-based protein and essential minerals such as magnesium, zinc, iron, copper, selenium and manganese. They also contain important vitamins like thiamine, vitamin B6 and vitamin K. For example, a small serving (about 28 g) provides significant portions of daily requirements for key micronutrients such as copper and magnesium.
Beyond micronutrients, cashews contain dietary fiber that supports digestive health and antioxidants that help protect cells from oxidative stress and inflammation. These health benefits make cashews attractive not only for direct consumption but also in foods such as nut butters, plant-based milks and trail mixes.
Health benefits supported by research
Studies suggest that regular, moderate consumption of cashews may support heart health by promoting healthy cholesterol levels, and contribute to sustained energy due to balanced macronutrient content. They may also play a role in supporting bone health, immune function and metabolic wellness because of their rich nutrient profile.
Cashew apple and by-product potentials
While the nut is the most widely commercialized part of the cashew tree, the cashew apple also holds significant value. Cashew apples are rich in vitamin C and sugars and show potential for processing into juices, jams and fermented beverages. Research shows that by-products such as cashew apple bagasse still carry beneficial nutrients and can be used in food formulations or eco-friendly packaging materials.
Emerging value streams
Innovation in the cashew value chain is not stopping at kernels. Cashew byproducts such as shell oil and dietary fibers are finding applications in industrial uses and food products. Cashew nut shell liquid (CNSL) is attracting interest for its use in resins, coatings and natural pest treatments.
Conclusion
As the Ghana cashew sector grows, embracing the nutritional and product potential of all parts of the cashew tree can spur local value addition, improve incomes and create new jobs. By combining quality production, smart processing and innovation, cashew can continue to be a core contributor to Ghana’s agricultural prosperity.
