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; DHA and EPA
IQ +6 -36%
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

Risks and Benefits of Fish Consumption
Outrageous claim:
“600,000 born annually with brain damage due to fish-eating mothers”
