Salmon, walnuts and flax seeds — sources of omega-3

Omega-3 fatty acids are linked to heart, brain and skin health. Here is where to get them if fish isn't part of your regular diet.

Omega-3 fatty acids are one of the few dietary components whose benefits are backed by dozens of studies, especially for the cardiovascular system.

Why you need omega-3

These fats are involved in cell membrane function, support vascular health, and are linked to normal nervous system function. Some studies also note a role in skin and joint health.

Sources if you don't eat fish

  • Walnuts and flax or chia seeds — plant sources of alpha-linolenic acid.
  • Soy products and some fortified foods.
  • Algae-based supplements — an alternative to fish oil for people who don't eat fish.

How much you need

The exact amount depends on age and health status — there's no universal number for everyone. With chronic conditions or blood thinners, taking supplements should be discussed with a doctor.
