Top 10 Plant-Based Foods Richest in Omega-3
Omega-3 fatty acids play an essential role in heart, brain, eye, immune and inflammatory balance health. They must absolutely be supplied through diet, especially when following a vegetarian or vegan diet.
In this comprehensive guide, discover the 10 plant-based foods richest in omega-3s, along with their precise ALA content.
What is plant-based omega-3 (ALA)?
Plant-based omega-3s are primarily found in the form of alpha-linolenic acid (ALA).
✔ Essential: the body cannot produce it.
✔ Indispensable: it contributes to cardiovascular, brain, and hormonal health.
ALA can be converted into EPA and DHA, active omega-3s, but the conversion is too low. Hence the importance of regularly consuming plant-based sources rich in omega-3s.
