The Bottom Line

  • A low-methionine diet delays ageing in animals.
  • If delaying ageing is your aim, methionine-restriction might be an easier option┬áthan┬ácalorie-restriction.
  • High levels of dietary methionine can exacerbate psychopathological symptoms in schizophrenic people.

Caveats

  • Severe methionine-restriction stunts growth in young animals.
  • Cutting out methionine completely is incompatible with life.

My advice

  • Eat more vegetables and fruit, which are low methionine foods.
