Because of astaxanthin's strong antioxidant properties, it has attracted attention for its possible health benefits. Knowing which foods have plenty of this compound helps anyone wanting to add it to their food choices.
1. Marine Organisms: The Primary Source
It is well known that marine life contains a high amount of astaxanthin. Salmon that comes from the wild is among the biggest types of fish. Species of salmon like Chinook and sockeye tend to gather astaxanthin in their wild diets since they usually eat organisms rich in that carotenoid. Besides making the flesh of salmon pinkish - red, astaxanthin also adds nutrients to its meal.
In addition, krill is considered an important ocean resource. Shrimps are a great source of astaxanthin because they contain a lot of it. Some people find that krill oil supplements popular, but eating or using foods made from krill in places where they are common is a good option too. In addition, lobster and crab types of shellfish also have astaxanthin. The shell and the flesh in shellfish often hold varying levels of carotenoids, but the outer shells are generally not eaten in large portions since they are not smooth or taste nice.
2. Microalgae: The Origin of Astaxanthin in the Food Chain
Astaxanthin is mostly produced by microalgae out in nature. This microalga, Haematococcus pluvialis, is famous for containing a lot of astaxanthin. To keep itself safe under stressful circumstances, the microalgae stores a lot of astaxanthin. Some people who watch what they eat are starting to use microalgae - based products or eat foods with microalgae. Even though people do not eat much microalgae, they are the main source of astaxanthin as they are the original holders of this compound in nature.
3. Poultry and Eggs: Secondary Sources
Some poultry products have low levels of astaxanthin. Astaxanthin might end up in the meat of chickens after eating animal feed with algae or seafood processing by - products. Still, the amount of formaldehyde in the air is usually much less.
If chickens get these nutritional benefits, their eggs may include some astaxanthin as well. Although a smaller amount is present in the yolk, astaxanthin does add to what makes an egg nutritious. This underlines that the health of livestock and products is influenced by the feed they get.
4. Processed and Fortified Foods
Over the past few years, more processed foods are being made with astaxanthin. There are energy bars that are enriched with astaxanthin. Besides, some sports drinks and nutritional supplements are made with astaxanthin to benefit from its antioxidants. Still, we should keep in mind that the astaxanthin in these foods might be natural or manufactured, so it's important to check if the astaxanthin is made correctly. You need to check the labels strictly to get an idea of what type of astaxanthin you are getting and how much.
In short, astaxanthin occurs in many types of food, yet salmon and krill are the most common sources. Microalgae are essential in nature's food chain, while poultry, eggs, and processed foods add something less important. If you know where astaxanthin comes from, you will be able to eat more of it based on what you like and your dietary needs.
