Ex Input:
Question: Is dietary docosahexaenoic acid-induced generation of liver lipid peroxides suppressed further by elevated levels of glutathione in ODS rats?
Answer: Higher than normal levels of dietary methionine are not necessarily associated with decreased dietary DHA-induced generation of tissue lipid peroxides and VE consumption except that the GSH requirement is increased in a condition such as acetaminophen feeding.

Ex Output:
no


Ex Input:
