Cashews are low in sugar and rich in fiber, heart-healthy fats, and plant protein. They’re also a good source of copper, magnesium, and manganese — nutrients important for energy production, brain health, immunity, and bone health. Cashew export from India has a long tradition of processing and exporting cashew kernels. The country’s cashew production is mostly concentrated in the coastal states of Kerala, Karnataka, Goa, and Maharashtra.
