Can you eat raw cashews?
Quick Answer
No
Raw cashews contain urushiol, a toxic substance that can cause skin rashes and can be harmful if ingested or inhaled. Therefore, cashews are typically sold pre-roasted, which neutralizes the toxin.
What Is It?
Raw cashews are the seeds of the cashew tree, which have not undergone any heat treatment or roasting.
Historical Context
The cashew tree is native to Brazil and was spread around the world by Portuguese explorers in the 16th century. The toxic nature of raw cashews was discovered when people who handled or consumed them experienced adverse reactions.
Why It Can Be Risky
Eating raw cashews can pose several health risks due to the presence of urushiol.
- Skin rashes: Contact with urushiol can cause skin rashes, similar to poison ivy.
- Digestive problems: Ingesting urushiol can lead to stomach pain and other digestive issues.
- Respiratory issues: Inhaling the smoke from burning raw cashews can cause respiratory problems.
Safe Method?
Cashews should always be heat treated or roasted before consumption. This process neutralizes the urushiol, making the cashews safe to eat.
Safe Alternatives
If you’re looking for a raw nut to include in your diet, consider almonds, walnuts, or pecans, which are safe to eat raw.
Storage Tips
Store cashews in a cool, dry place in an airtight container to maintain their freshness.
Preparation Tips
Before using cashews in recipes, ensure they have been properly roasted. They can then be used whole, chopped, or ground in a variety of dishes.
