All You Need to Know About Cashew Grades & Cashew Kernels

Cashew is a highly nutritious and concentrated form of food, providing a substantial amount of energy. The cashew nut kernel has a pleasant taste and flavor and can be eaten raw, fried and sometimes salted or sweetened with sugar. It also contributes as an important source of invisible fat in the diet, being widely used in a variety of ways. There has been a growing demand for cashew in many temperate countries where the demand is increasing. The nut contains an acrid compound which is a powerful vesicant that is abrasive to the skin. The cashew shell contains 25% of this reddish brown oil, industrially known as Cashew Nut Shell Liquid (CNSL) which is a by-product of the roasting process.

Types of Cashew grades

Cashew grades refer to the classification of cashew nuts based on their size, shape, color, and quality. The grading system helps determine the value and marketability of cashew nuts. Here is some information about cashew grades:

  • Whole Cashews: Whole cashews are the highest grade and most desirable. They have a uniform shape, size, and color. Whole cashews are often used for snacking or as an ingredient in various dishes.
  • Split Cashews: Split cashews are whole cashews that have been manually or mechanically split into two halves. They are commonly used in cooking and baking.
  • Broken Cashews: Broken cashews are cashew nuts that have broken into smaller pieces during processing. They are often used in the food industry for making cashew butter, cashew milk, or as an ingredient in confectionery products.
  • Scorched Cashews: Scorched cashews have a slightly darker color due to over-roasting during processing. They may have a slightly different flavor compared to regular cashews.
  • Dessert Cashews: Dessert cashews are cashews that have been roasted with sugar or other sweeteners. They have a sweet and crunchy taste and are often used in desserts or as a topping for ice cream.
  • Cashews Pieces: Cashew pieces refer to small fragments or irregularly shaped cashew nuts. They are often used in cooking, baking, or as an ingredient in snack mixes.

Health benefits of Cashews

Cashews are not only delicious but also offer several health benefits. Here are some of the key health benefits of cashews:

  • Heart health: Cashews are rich in monounsaturated fats, which are considered heart-healthy fats. These fats help lower bad cholesterol levels (LDL) and increase good cholesterol levels (HDL), reducing the risk of heart disease.
  • Nutrient-rich: Cashews are packed with essential nutrients such as vitamins (vitamin E, vitamin K, and B vitamins), minerals (copper, magnesium, zinc, and phosphorus), and antioxidants. These nutrients support overall health and contribute to various bodily functions.
  • Weight management: Despite being calorie-dense, cashews can aid in weight management. The combination of healthy fats, protein, and fiber in cashews helps promote satiety, keeping you feeling full for longer and reducing overeating.
  • Bone health: Cashews contain minerals like magnesium, copper, and phosphorus, which are essential for maintaining strong and healthy bones. These minerals contribute to bone density and help prevent conditions like osteoporosis.
  • Blood sugar control: Cashews have a low glycemic index, meaning they cause a slower rise in blood sugar levels compared to high-glycemic foods. This makes them a suitable snack option for individuals with diabetes or those looking to manage blood sugar levels.
  • Eye health: Cashews are a good source of antioxidants like lutein and zeaxanthin, which are beneficial for eye health. These antioxidants help protect the eyes from damage caused by harmful free radicals and may reduce the risk of age-related macular degeneration.
  • Improved digestion: Cashews contain dietary fiber, which aids in digestion and prevents constipation. Fiber also promotes a healthy gut microbiome, supporting overall digestive health.
  • Reduced inflammation: Cashews contain compounds like polyphenols and antioxidants that possess anti-inflammatory properties. Regular consumption of cashews may help reduce inflammation in the body and lower the risk of chronic diseases associated with inflammation.

It's important to note that while cashews offer numerous health benefits, they are also high in calories. Therefore, it's essential to consume them in moderation as part of a balanced diet.

Health benefits of Cashews for Men

  • Prostate health: Cashews are rich in zinc, a mineral that plays a crucial role in maintaining prostate health. Adequate zinc intake has been associated with a reduced risk of prostate issues, including enlargement and cancer.
  • Testosterone production: Zinc is also essential for testosterone production in men. Testosterone is a hormone that plays a vital role in male reproductive health, muscle growth, bone density, and overall well-being. Cashews' high zinc content can support healthy testosterone levels.
  • Heart health: Heart disease is a significant concern for men. Cashews contain monounsaturated fats, which can help lower bad cholesterol levels (LDL) and increase good cholesterol levels (HDL). This can reduce the risk of heart disease and promote cardiovascular health.
  • Muscle growth and recovery: Cashews are a good source of protein, which is essential for muscle growth and repair. Adequate protein intake is crucial for men who engage in regular exercise or strength training to support muscle development and recovery.
  • Energy and stamina: Cashews are a rich source of vitamins, minerals, and healthy fats, providing a good energy boost. The combination of protein, healthy fats, and carbohydrates in cashews can help improve stamina and endurance, making them a great snack option for active men.
  • Bone health: Cashews contain minerals like magnesium and phosphorus, which are essential for maintaining strong and healthy bones. These minerals contribute to bone density and can help prevent conditions like osteoporosis.
  • Mental health: Cashews contain nutrients like magnesium and vitamin B6, which are important for brain health and mood regulation. Adequate intake of these nutrients can support cognitive function and help reduce the risk of mental health issues such as depression and anxiety.

It's important to note that while cashews offer numerous health benefits for men, they should be consumed in moderation as part of a balanced diet.
