  • Processing: The native Tupi-Indian tribe taught the Portuguese how to roast cashews to remove the irritating shell.

Modern History

  • 1905: Cashews reached the United States but did not gain popularity until the 1920s.
  • 1941: India was shipping around 20,000 tons of cashews annually to the U.S.
  • Today: Cashews are mainly grown in West Africa, India, Tanzania, and Vietnam.

Cultivation and Processing

  • Optimal Conditions: Cashew trees thrive in warm, humid climates and sandy soil.
  • Toxic Shell: The cashew seed has a double shell containing a toxic, allergenic substance that must be removed before eating.
  • Processing: After harvesting, the nuts are dried, roasted, shelled, and processed to remove the irritants and skin.

  • Antioxidants: Cashews contain antioxidants like polyphenols and carotenoids that protect cells from oxidative damage and reduce inflammation in the body.
  • Disease Prevention: The antioxidants in cashews may help prevent conditions like Parkinson's, Alzheimer's, and multiple sclerosis.

Weight Management

  • Satiety: The protein, fibre, and healthy fats in cashews can promote feelings of fullness, aiding in weight loss or maintenance.
  • Calorie Absorption: Research suggests that the body may only absorb around 84% of the calories in cashews, meaning some of the fat content is not fully digested.
