Omega 3 fatty acid
Omega 3 fatty acids or ω-3 are essential polyunsaturated fatty acids, meaning they can't be made in the body and must come from food.. Omega 3 is necessary for a healthy metabolism. Dietary sources of omega 3 fatty acids include certain plant oils, marine oils such as algal (algae) and fish oils.
Types[edit | edit source]
The types of omega 3 fatty acids essential for the human body are:
- Alpha linolenic acid (ALA), found mainly in plants including flaxseed oil (linseed oil), rapeseed oil, certain nuts, pumpkin seeds, soybean products, and green leafy vegetables
- Eicosapentaenoic acid (EPA), which the body can make from ALA, and also found in some algal oils, and fish oils
- Docosahexaenoic acid (DHA), which the body can make from ALA, and also found in algal oils, and fish oils
