Lathyrism is caused by excessive consumption of Kesari dal.

Lathyrism is a neurological disorder that is caused by the excessive consumption of a legume called Kesari dal, which is also known as Khesari dal or Lathyrus sativus. Kesari dal contains a neurotoxic amino acid called beta-N-oxalylamino-L-alanine (BOAA). When consumed in large quantities over a prolonged period, BOAA can lead to the development of lathyrism.

Lathyrism primarily affects the nervous system and can result in symptoms such as muscle weakness, paralysis, and irreversible damage to the spinal cord. It is more common in regions where Kesari dal is a dietary staple and consumed in large amounts.

It`s worth noting that excessive consumption of other food items or substances, such as mustard oil, polished rice, or mushrooms, does not cause lathyrism. Each of these substances may have their own health effects or risks, but they are not associated with lathyrism.
