Aquaculture in a Healthy Diet

Jogeir Toppe (FAO), Vilnius, 29 September 2016

Food security for all

“make sure people have regular access to

enough high-quality food to lead active,

healthy lives”

Aquaculture is increasing the availability of fish

Proteins

• 17 % of animal protein from fishmore than 50 % in many of the poorest countries

• Increasing evidence on health benefits of fish proteins/peptides

Fish protein vs animal protein

Omega-3 Fatty Acids marinevegetable

• Marine origin:– Eicosapentaenoic acid (EPA); C20:5 ω-3

– Docosahexaenoic acid (DHA); C22:6 ω-3

• Vegetable origin: – Alfa linolenic acid (ALA); C18:3 ω-3

– <5% converted to EPA

– <0,5% converted to DHA
