What is A carotenoid and what does it do?
Carotenoids are pigments in plants, algae, and photosynthetic bacteria. These pigments produce the bright yellow, red, and orange colors in plants, vegetables, and fruits. Carotenoids act as a type of antioxidant for humans.
What is carotenemia mean?
First described in 1919 by Hess and Meyers, carotenemia is the medical terminology describing yellow-orange skin pigmentation due to high levels of carotene in blood. Excessive consumption of fruits and vegetables high in carotene content is often the culprit.
What happens if you have too much beta-carotene?
Beta-carotene doesn’t seem to be toxic in large doses. But high doses over a long time can lead to carotenemia. This causes your skin to become yellowish orange.
What does beta-carotene do?
In the body, beta-carotene converts into vitamin A (retinol). We need vitamin A for good vision and eye health, for a strong immune system, and for healthy skin and mucous membranes. Taking big doses of vitamin A can be toxic, but your body only converts as much vitamin A from beta-carotene as it needs.
How do carotenoids work?
Dietary carotenoids are thought to provide health benefits in decreasing the risk of disease, particularly certain cancers and eye disease. The carotenoids that have been most studied in this regard are beta-carotene, lycopene, lutein, and zeaxanthin.
How do you get carotenoids?

What causes hypercarotenemia?
The most common reported cause of hypercarotenemia (and thus carotenoderma) is increased intake, either through increased dietary foods or nutritional supplements. This change takes approximately 4 to 7 weeks to be recognized clinically. Numerous ingested substances are rich in carotenoids.
What causes high carotene?
Excessive dietary intake of carotene-rich food is by far the most common cause of carotenemia. In rare cases, it can result from systemic diseases like diabetes mellitus, nephritic syndrome, glomerulonephritis, hypothyroidism, anorexia nervosa, and primary hepatic disease.
What happens if you eat carrots everyday?

How do I get more carotenoids?
Where do carotenoids come from?
Carotenoids are a class of more than 750 naturally occurring pigments synthesized by plants, algae, and photosynthetic bacteria (1). These richly colored molecules are the sources of the yellow, orange, and red colors of many plants. Fruit and vegetables provide most of the 40 to 50 carotenoids found in the human diet.
What are carotenoids and what do they do?
Carotenoids are responsible for the brilliant yellows and oranges that tint deciduous foliage (such as dying autumn leaves) of certain hardwood species as hickories, ash, maple, yellow poplar, aspen, birch, black cherry, sycamore, cottonwood, sassafras, and alder.
What are unoxygenated carotenoids called?
The unoxygenated (oxygen free) carotenoids such as α-carotene, β-carotene, and lycopene, are known as carotenes. Carotenes typically contain only carbon and hydrogen (i.e., are hydrocarbons), and are in the subclass of unsaturated hydrocarbons.
Why do nutritionists encourage people to incorporate natural sources of carotenoids?
That is why nutritionists encourage people to incorporate natural sources of these compounds into their diet. It is worth noting that your body cannot synthesize these compounds; so, you need to increase the intake of foods that have carotenoids.
