When we talk about omega-3, this includes the following three fatty acids: alpha-linolenic acid (ALA), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). ALA is one of the essential fatty acids and must therefore be taken in with food. The long-chain omega-3 fatty acids DHA and EPA can be produced from this fatty acid, but the conversion rate is only 5-10%. Therefore, the intake of DHA and EPA through food is also extremely important.
ALA is found in various vegetable oils such as rapeseed, walnut and linseed oil. DHA and EPA are mainly found in fatty cold-water fish and algae respectively.
Fish oil vs. algae oilFish consumption is often recommended to increase the intake of omega-3 fatty acids. However, the origin of these healthy fatty acids lies in the plant world: algae, grasses and seeds. However, the only plant-based source of omega-3 comparable to fish is algae. This is because algae, like fish, have an optimal content of DHA and EPA. This is how fish get their omega-3 fatty acids: they eat the algae.
However, the detour via fish has some significant disadvantages. What many people don't know: The omega-3 content of fish can also vary enormously depending on the fish species, aquaculture or wild catch. Only cold-water fish rich in fat, such as salmon or tuna, have a high omega-3 fatty acid content. The problem here, however, is the overfishing of the oceans and the resulting destruction of marine habitats.
Pollutant and antibiotic contamination in fishWild fish also absorb a lot of pollutants in the sea during their lifetime. These include heavy metals such as mercury, dioxins, polychlorinated biphenyls (PCBs) and microplastics, which can then accumulate in the fish flesh. The content of harmful substances in many fish species is so high that pregnant women, nursing mothers and children should refrain from eating fish.
However, conventional aquacultures are not an alternative either. The fish from the farms are often contaminated with antibiotics or other medicines and lead a life in factory farming. The fish feed used (= fishmeal) is also required in large quantities, resulting in the capture of many marine creatures.
