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

Caveats

• Severe methionine-restriction lowers fertility in animals.
• 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.
