Cashew nuts or Kaju are technically not nuts but seeds. The scientific name of cashew nuts is Anacardium Occidentale L. and belongs to the family Anacardiaceae.
Cashew nuts grow on evergreen trees, which are native to Brazil and later expanded to South American countries. The Portuguese introduced cashew nuts in India and Africa in the 16th century.
A single-seeded nut in a hard grey shell grows at the bottom of the cashew apple (a soft and juicy fruit). There are 33 varieties of cashew nuts identified, out of which only 26 varieties are marketed. The W-180 variety is known as the “king of cashews”.
Cashew nuts are a popular ingredient known for its rich nutty flavour and is used in various Indian dishes and as a dairy alternatives like cream and cashew milk. As for the nutritional composition, cashew nuts are rich in tocopherols, phytosterols, phenolic lipids and several bioactive compounds, all of which have several benefits to human health1.
Cashew nuts provide a range of nutrients per 100g serving, as outlined below2:
Cashews have several vital nutrients such as vitamins like vitamin B (thiamine and folate), E, and K. Additionally, they are abundant in minerals like magnesium, phosphorus, copper, and zinc, which are crucial for several body processes11.

Scientific literature has found that cashew nuts show numerous properties as those mentioned below:
Some of the potential benefits of cashew nuts are described below.
Consumption of cashew nuts may exert a cardio-protective effect. A study5 conducted to assess the effects of cashew nut consumption on blood pressure and cardiovascular risk factors supported that consumption of cashew nuts may improve triglyceride levels and systolic and diastolic blood pressure. However, the same study did not find significant effects on other factors like HDL cholesterol or total cholesterol. While these findings are promising, further high-quality research is needed to confirm the potential benefits. Cashew nuts should be consumed in moderation as part of a varied and balanced diet.
Cashew nuts are rich in proanthocyanidins, a flavanol that is associated with cancer cell replication. Additionally, the presence of copper and other minerals may help reduce the risk of colon cancer. Thus, this may indicate consumption of cashew nuts may exert an anti-cancer effect. However, we need enough studies to support these claims6.
Proinflammatory cytokines like TNF-alpha and IL-6 are involved in the development of chronic pain. Cashew nuts have been found to exhibit anti-inflammatory and pain-relieving (analgesic) properties, potentially by reducing the production of these inflammatory molecules. They also possess antioxidant activity, which may help protect cells from damage caused by harmful free radicals. These properties suggest that including cashew nuts in the diet may help support the body’s natural response to inflammation and discomfort. However, further research in humans is needed to confirm these potential effects7.
Haemoglobin is a protein that enables red blood cells to carry oxygen. Iron and copper are essential micronutrients required for the production of haemoglobin. Cashew nuts are a source of iron and copper and thus may help in the formation of haemoglobin. Additionally, the consumption of cashew nuts may help in managing blood disorders. However, scientific evidence supporting these claims is limited, and we need more studies to confirm these findings6.
Cashew nuts contain zeaxanthin, an antioxidant known to protect the macula of the eyes from external damage and improve eyesight. This may indicate that the consumption of cashew nuts can help improve vision. However, scientific evidence supporting these claims is limited, and we need more studies to support these claims6.
Cashew nuts may help in improving brain function. Chemobrain is a term for the adverse effects of chemotherapy-induced brain deterioration. There are no drugs which are available to cure the weakening of the brain caused due to chemotherapy. A study8 conducted in 2022 to assess the effects of cashew nuts consumption on cisplatin-induced brain harm in rats showed that cashew nuts could be used as a functional food to manage cisplatin-induced neurotoxicity. This indicates that the consumption of cashew nuts may help improve brain function. However, we need more studies to confirm these claims7.
Cashe nuts may help in managing diabetes, supporting bone health, and improving brain function. Additionally, cashew nuts may contribute to healthy weight management and provide nourishment to the hair. Some evidence also suggests they may assist in the prevention of certain blood disorders9.
To my knowledge, cashew nuts offer multiple health benefits as they are packed with micro and macronutrients. They are believed to contain natural compounds that could contribute to immune function, exhibit antioxidant properties, and support general wellness. Some studies12 also suggest that they may also play a role in maintaining skin health and supporting iron intake.
