Omega-3 fatty acids are essential fats that play important roles in heart health, brain function, inflammation control, and overall wellness. Because the body cannot produce omega-3s efficiently, they must come from food or supplements.
There are three primary types of omega-3 fatty acids:
EPA (eicosapentaenoic acid)
DHA (docosahexaenoic acid)
ALA (alpha-linolenic acid)
EPA and DHA are mainly found in marine foods, while ALA is found in plant sources.
Fatty Fish Rich in Omega-3s
Fatty fish are among the best sources of EPA and DHA.
Salmon
One of the most nutrient-dense omega-3 sources, salmon supports heart and brain health.
Mackerel
Rich in healthy fats and vitamin D.
Sardines
Small fish with high omega-3 content and low mercury levels.
Herring
Commonly eaten pickled or smoked.
Anchovies
A concentrated source of omega-3 fats and minerals.
Tuna
Contains moderate omega-3 levels, especially albacore tuna.
Plant-Based Omega-3 Sources
Flaxseeds
