Plant substances

They are found in fruits, vegetables, legumes, nuts and whole grain products:Secondary plant substancesThey serve as protection for plants from predators, germs, bacteria and diseases as well as from harmful UV light. They give them their colour, scent and taste. Aseffective vital substances for human healthThey are now increasingly coming to the fore. They are considered highly potentAntioxidants, have anti-inflammatory and antibacterial effects. It is estimated that there are more than50,000 secondary Plant substances. Its most famous representatives includeCarotenoids,AnthocyaninsandPolyphenols, which also includeFlavonoidsWell researched and particularly valuable secondaryPlant substancesare for example in carrots,tomatoes,Krill oil,Green tea,ginkgo, pumpkin and red wine grape seeds, blueberries andCranberriescontain.

Valuable antioxidant: Astaxanthin

Krill, salmon, flamingos - they all owe their pink colouring to the carotenoidAstaxanthin, which occurs naturally in microalgae. It enters the organism of animals and humans via the food chain. Astaxanthin is considered one of thestrongest antioxidantsIt can neutralize free radicals at the cell membrane and thus provides active cell protection. Studies have shown that this valuableCarotenoidsseveral health-promoting effects can be attributed to it. It can Eye healthandImmune defensestrengthen and supports the body inCardiovascular diseases. People who are physically active also benefit from the secondary plant substance. A scientific study from Sweden found that physical performance, especially strength and endurance, was improved byAstaxanthinAthletes who take astaxanthin report afaster recoveryafter training,less painandfewer injuriesduring intensive sports sessions.

This can lead to damage andpremature skin agingA particularly good source of astaxanthin is high-qualityKrill oil. It is extracted from small crustaceans that are native to the clean waters of Antarctica. Krill oil naturally contains astaxanthin andOmega-3 fatty acids, whichPhospholipidsare bound.

The eye professionals: Lutein and Zeaxanthin

The twoVital substancesLuteinandZeaxanthinare concentrated in the human eye in the "yellow spot", the so-called "macula lutea". This is the area with the highest visual activity in the eye. BothCarotenoidssupport a healthy metabolism, absorb dangerous UV radiation and neutralizeFree radicals.They act like “internal sunglasses”. Numerous studies indicate that both vital substances are helpful in preventingsevere eye diseasesplay an important role, includingCataractand age-related changes in the retina, such as the so-calledMacular degeneration (AMD), which can lead to a loss of vision in old age.Lutein and zeaxanthincannot be produced by the body itself and must be ingested with food. There is scientific evidence that the body can convert the carotenoid lutein into zeaxanthin when needed.Lutein, zeaxanthin and astaxanthinstructurally belong to the same family ofBeta-caroteneThey are found in particularly high concentrations in kale, parsley, spinach, broccoli, lettuce, peas, Brussels sprouts, green beans, corn, raw carrots and tomatoes.

What does “secondary” mean?

There areprimary plant substancessuch as fat, protein and carbohydrates, from which secondary plant substances are produced in the plant's own metabolism (secondary metabolism). In all plant foods such as infruit and vegetablesThey fulfil protective functions such as protection against UV light. They are found on the outer layers of the plants, in the peel and in the outer leaves. Therefore, an apple should be eaten with the peel if possible, as this is where most of thesecondary plant substancesSome secondary plant substances are poisonous to humans in their natural state. Therefore, certain vegetables, such as beans, should not be eaten raw.

Topic: Bioavailability

Secondary plant substances such as carotenoids, whichwith oilare particularly harmful to the human organismbioavailableThis also applies to food supplements containing secondary plant substances dissolved in oil. A particularly good example of this is the 100% natural Krill oil, because this fish oil naturally contains theCarotenoid Astaxanthin.
