Astaxanthin has been one of the demanded antioxidants in dieting, given its claims with regard to positive health advantages. Astaxanthin is a healthy component found on the food that is available to most individuals. There is always a question of, what are the foods that contain astaxanthin since it means that people are getting health conscious. By revealing the dietary derivation of this vivid red - orange carotenoid, one can help people make sound nutritional decisions to ingest its benefits into their lives. So, what other types of foods contain the astaxanthin ingredient? Let us discuss it in more detail.
Marine Marvels: Seafood Rich in Astaxanthin
One of the biggest sources of astaxanthin in the human diet is seafood. One of the most popular fish and the fish with the most nutritional value and rich taste is salmon, which is rich in this antioxidant. The Wild - caught salmon, especially, has a typical pink - red coloring due to astaxanthin they accumulate by feeding upon microalgae and other small animals at their natural habitat. Another fish that has a lot of astaxanthin is trout. Trout, as well as salmon, get their diet which contains this carotenoid in fresh water conditions and this is a factor in giving them this coloration and their nutritional content.
The other marine sources of astaxanthin are shrimp and krill. When cooked, shrimp turn reddish - pink indicating the presence of the astaxanthin in the body tissues. Krill are small crustaceans that inhabit oceans, and contain exorbitant amounts of astaxanthin, so they play a key role in the food chain in that body of water. In the case of humans, in addition to having an exquisite culinary pleasure, the consumption of these seafood products will be the natural means of enhancing astaxanthin intake as well.
Algal Origins: Microalgae as Astaxanthin Powerhouses
The natural source of astaxanthin is microalgae, and some species contain a lot of this compound. Haematococcus pluvialis, especially, is the most famous astaxanthin source, which is also provided in nature. This green micro alga synthesizes large amounts of astaxanthin when placed under certain environmental conditions such as high intensity of light causing a strain or even when it is deprived of food turning it to a deep red color. Consequently, Haematococcus pluvialis supplements have gained popularity in people interested in boosting their astaxanthin intake.
The other form of microalgae that has astaxanthin in it is chlorella though it is in smaller amounts than those found in Haematococcus pluvialis. Many people take Chlorella in a powdered or tablet form and although the level of astaxanthin may not be so high, it still adds up to the level of antioxidants consumed into the diet system. These sources of the algal sources point out the significance of the natural production of astaxanthin and its accessibility to the consumption by the human being in a numerous goods.
Surprising Sources: Eggs and Poultry with Astaxanthin
Although astaxanthin is a well - recognized ingredient in seafood and microalgae, it can be found also in eggs and poultry. Carotenoid can be passed onto eggs when hens are given diets enriched with the pigment, i.e., ingredients containing astaxanthin including some algae or seafood by - products. This causes yolks that are a more orange color, which means more astaxanthin. In the same way, astaxanthin trace amounts can as well occur in the poultry meat when birds were provided with the astaxanthin - enriched diet. These studies indicate that astaxanthin is present in human diet in more widespread food products, which is determined by feeding habits in livestock.
Plant - Based Possibilities: Indirect Astaxanthin Sources
Even though plants do not produce astaxanthin by themselves, it is possible to indirectly relate some plant - based foods to this antioxidant. As an example, some kinds of seaweed, which are cultivated in marine habitats in the presence of astaxanthin - producing microalgae, can absorb, ingest, or otherwise accumulate minor amount of astaxanthin. Also, there are small amounts of it in certain plant oils (particularly of plant sources likely to be exposed to marine - derived carotenoid astaxanthin during production or culture in coastal regions). Although these plant - based sources cannot be as concentrated as seafood and algae, they still provide modest contribution of astaxanthin to the overall intake of an individual.
To conclude, astaxanthin occurs in many food sources, ranging at the bottom of the ocean to be diet and supplements that are microalgaes. By making these food sources of astaxanthin, part of your diet, it is conceivably possible that you will receive antioxidant protection and better general health.
