What happened

Growing up in Nara, Japan, my daily diet included staples like fish, soy and seaweed.

Why it matters

These foods are all sources of omega-3 fatty acids, an essential fat your body can't make on its own and must get from food.

Common ground

Omega-3s come in three key forms — DHA, EPA and ALA — and each supports your health in a different way.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
