The cashew nut is encased in a shell attached to the cashew apple, which is also edible. Cashews are prized for their rich, creamy flavor and are consumed in various forms, including roasted, salted, or used in cooking and baking.

Side Effects of Cashews
While cashews offer many benefits, they can have some side effects, especially when consumed in excess or if you have specific sensitivities:
Allergic Reactions
Cashews are tree nuts and can cause allergic reactions in some individuals. Symptoms can range from mild itching or hives to severe anaphylaxis.
High Calorie Content
Cashews are calorie-dense, so consuming them in large quantities can contribute to weight gain. Moderation is key, especially for those on a calorie-restricted diet.
Kidney Stones
Cashews contain oxalates, which can contribute to the formation of kidney stones in susceptible individuals. Those prone to kidney stones may want to limit their intake.
Excess Sodium
Salted or roasted cashews may have high sodium content, leading to water retention and high blood pressure. Opt for unsalted versions if you’re watching your sodium intake.
Digestive Issues
In some people, excessive consumption of cashews may lead to bloating, gas, or other digestive discomfort due to their fiber content.
How to Include Cashews in Your Diet

In Cooking: Use cashews in curries, stir-fries, and sauces. Cashew cream is a dairy-free alternative for creamy sauces and desserts.
In Baking: Add cashews to cakes, cookies, and granola for a nutty flavor.
Cashew Butter: A healthy alternative to peanut butter, ideal for spreads, smoothies, or baking.
