Fat or Water Soluble Antioxidant:
Since they are fat-soluble nutrient, Carotenoids such as Lutein, require the presence of dietary fat for proper absorption through the digestive tract. Consequently, your carotenoid status may be impaired by a diet that is :
§ pancreatic enzyme deficiency
§ Crohn's disease
§ celiac sprue
§ cystic fibrosis
§ surgical removal of part or all of the stomach, gall bladder disease
§ Liver disease.
Lutein appears to work in partnership with Zeaxanthin, another Carotenoid antioxidant, tackling the same health issues and performing similar functions.
Both are present in the eyes and skin.
In the eyes, they appear to exist in a certain ratio. The suggested ratio is 2:1 (Zeaxanthin to Lutein), for adults. Therefore, taking one carotenoid and not the other, may reduce their effectiveness as eye care. Additionally, taking them in the incorrect ratio will also reduce their effectiveness – such as, taking too much Lutein and not sufficient Zeaxanthin, the access Lutein is not absorbed by the eyes, as the ratio of Zeaxanthin to Lutein, in the eyes, has to be maintained.
Other functions besides being an antioxidant:
It is found it
both plants and animals, however, even in animals, the lutein is derived from
Lutein is found in the human body:
We are born with Lutein in our body but because our body does not produce lutein, we need to replenish the Lutein through foods and/or supplements.
Examples of food sources:
In plant foods : [Cite: Wikipedia]
Product Lutein/zeaxanthin (micrograms per hundred grams):
The process of heat (from cooking or otherwise) can destroy the levels of Lutein in the foods.
Examples of the health benefits of Lutein:
o neutralizing the damaging effects of free radicals in the macular area
o Absorbing the UV and blue light, preventing the formation of free radicals caused by UV and blue light
o Cataract – free radicals damages the protein on the lens of the eyes
As a food additive :
o Extract of the petals of marigold (Tagetes erecta)
o Approved for use in the EU and Australia and New Zealand, but is banned in the USA.
