In addition, these nuts are rich in proteins, essential minerals, and vitamins that promote your body’s healthy functioning. These tasty nuts are used in sweet and savory dishes and for making nut butter, vegan milk, and baked goods. Although cashew nuts are considered nuts, technically, they are not. They are seeds of Anacardium occidentale, a native Brazilian tree that is evergreen. In the article below, we will learn all about cashew nuts, their nutritional profile, the benefits they offer, their possible side effects, and precautions to take while consuming them.

Nutritional Profile Of Cashew Nuts
Cashew nuts are considered to be one of the most nutritious foods in the world despite being rich in calories and low in fiber as they are packed with healthy fats, vitamins, and antioxidants. They contain many essential fatty acids that are beneficial for the body (1). One ounce (28.3 g) of cashew nuts contains 157 calories, 8.5 g of carbohydrates, 5.1g of protein, 12.4 g of fat, 0.3 mg of vitamin E, 9.5 mcg of vitamin K, 0.1 mg of vitamin B6, 10.4 g of calcium, 3.4 mg of sodium, 187 mg of potassium, 83 mg of magnesium, and 7 µg of folate. Since cashew nuts contain so many amazing nutrients, they are purported to provide a host of health benefits. Check them out in the next section.
13 Health Benefits Of Cashew Nuts
1. Boosts Heart Health
Compared to other nuts such as walnuts and almonds, cashews are low in fat and cholesterol and high in nutrients (2). In fact, they are rich in phytosterols, phenolic compounds, and oleic acid (1). Thus, it could be extremely beneficial for the heart. A study that was published in the American Journal of Clinical Nutrition recommends taking nuts of all sorts – including cashew nuts – in low doses to your daily diet as it can prevent ischemic heart diseases and cardiovascular diseases (3). Regular consumption of healthy unsaturated fats, such as monounsaturated and polyunsaturated fatty acids (MUFA and PUFA), can prevent cardiovascular disease even in people suffering from diabetes (4). These fatty acids are found in abundance in cashew nuts (1). The key is to consume them in moderation as cashews are rich in calories. A meta-analysis of 14 studies has found that the risk of coronary heart disease is 37% lower in people who consume nuts more than four times per week compared to those who never or seldom consume nuts. However, this claim needs to be experimentally validated (5).
2. Lowers High Blood Pressure
Cashew nuts are rich in healthy unsaturated fats and minerals like magnesium, potassium, and L-arginine (1). According to a 12-week study conducted on Asian Indians with type 2 diabetes, the consumption of cashew nut can reduce systolic blood pressure and increase HDL (good) cholesterol without having a negative effect on body weight, glycemia, or other lipid variables (6), (7). Cashews also contain an amino acid called L-arginine (2). L-arginine can help reduce blood pressure as it is a precursor to nitric oxide (NO), which is a vasodilator (8).
3. May Boost Your Immunity
Cashew nuts are rich in zinc (1). Zinc is an immune-boosting compound that is vital for basic cell processes such as cell division, transcription, and regulation. It also plays a role in certain immune processes such as cytokine production and phagocytosis (9). Regular intake of cashews can help in reaching the recommended daily allowance for zinc.
4. An Excellent Source Of Antioxidants
Cashew nuts are considered healthy nuts as they are rich in antioxidants such as tocopherols (1). Tocopherols help eliminate free radicals and protect our cells from cell damage caused by oxidative stress (2), (10). Cashew milk contains plant sterols, which are natural antioxidants that help strengthen the immune system and prevent the onset of chronic diseases (11).
5. May Prevent Gallstones
Frequent nut consumption can reduce the risk of developing gallstones (2). Gallstones are hard deposits of cholesterol and other minerals. Since cashews have the ability to lower levels of cholesterol, they may also help in preventing the formation of gallstones (3). However, there is no scientific evidence to prove the same. A study conducted by Harvard Medical School and Brigham and Women’s Hospital found that women who eat 5 oz of nuts per week are at a reduced risk of cholecystectomy (a surgical procedure to remove your gallbladder) than women who consume less than 1 oz of nuts per week (12).
6. May Be Good For Skin And Hair Health
Cashew nuts are high in antioxidants, copper, magnesium, iron, and selenium (1), (2). Antioxidants scavenge harmful chemicals and repair the tissues. Thus, they help improve the health and appearance of your skin. Copper improves the production of elastin and collagen (13). Collagen is an integral structural protein that is responsible for the elasticity of your skin and hair. Including collagen-boosting foods such as cashews in your daily diet can help keep your skin glowing and hair healthy.
7. May Help Strengthen Bones
Cashew nuts are rich in proteins and minerals such as magnesium and copper (1). Copper helps in keeping your joints flexible by synthesizing collagen. It also helps in the formation of bones along with magnesium (14). Therefore, eating a few cashew nuts every day may help strengthen your bones.
8. May Prevent Macular Degeneration
Cashews contain zeaxanthin and lutein, which are important antioxidants (1). Xanthophylls such as zeaxanthin and lutein significantly increase macular pigment, chromatic contrast, and photo stress recovery time (15). Thus, consuming cashews regularly may help in keeping your eyes healthy.
9. May Help In Managing Weight Loss
Cashew nuts, though rich in calories, do not increase weight when consumed in moderation. Studies done on 51,188 women during a period of 8 years have shown that including nuts in the diet can reduce the risk of gaining weight (16). There are various hypotheses behind this claim though no experimental evidence is available. One theory suggests that since cashew nuts are rich in nutrients and healthy fats that reduce cholesterol, blood pressure, and the risk of heart disease (factors connected to obesity), they may be helpful in weight management by association (17). Cashew nuts also curb hunger pangs and fill you up for a longer time, thus preventing you from binge eating (17).
10. May Prevent Cancer
In general, studies have shown that regular nut consumption reduces the risk of cancer (18). Cashew nuts are rich in antioxidants compounds such as anacardic acid, cardanols, and cardols that may help reduce the risk of cancer (19). A study conducted by Brigham and Women’s Hospital and Harvard Medical School found that adolescent girls who eat nuts regularly are a lower risk of developing breast cancer (20). The inositol and anacardic acid in cashew nuts may help fight cancer and increase the chances of survival by inducing cell cycle arrest and apoptosis and inhibiting cell proliferation and metastasis (21).
11. May Help Manage And Prevent Diabetes
Interestingly, though cashew nuts are high in calories, they have been reported to benefit people with diabetes. A study has shown that the long-term consumption of cashew nuts may lower the risk of type 2 diabetes by enhancing glycolysis and increasing glucose uptake (22). However, it is recommended to consume only 4-5 cashews per day in such cases. Cashews are cholesterol-free and have been reported to lower blood pressure and cholesterol in people with diabetes (7). Cashew nuts are also rich in polyphenols that can help improve the gut microbiome and reduce the risk of developing type 2 diabetes (23).
12. May Promote Nerve Health
Fatty acids help in the formation and functioning of the myelin sheaths of neurons (24). The fatty acids present in cashews may help with the same. Cashews are also a rich source of magnesium (1). Magnesium helps maintain nerve function (25).
13. Reduces The Risk of Anemia
Cashew nuts are rich in both iron and copper (1). These minerals are essential for the proper functioning of the circulatory system. Iron deficiency is a common cause of anemia, and incorporating cashew nuts in your daily diet can help prevent it. Isn’t it fascinating how great cashew nuts are for your health? So, let’s check out how you can add it to your diet.
