It is not found preformed in plant-based diets (unless fortified), but it is found "preformed" (in its active state) in some animal-based food products. One chemical belonging to the carotenoid family is beta carotene.
The FDA has approved beta-carotene for use as a nutritional supplement and even as an additional source of vitamin A in baby formula.
30 to 300 mg of beta-carotene (corresponding to 50,000 to 500,000 units of vitamin A activity) should be consumed daily by adults and teenagers. For children, 30 to 150 mg of beta-carotene (corresponding to 50,000–250,000 units of vitamin A activity) should be consumed daily.
Since beta-carotene is not heat-sensitive, it is not destroyed by quick cooking; in fact, the softening of the plant tissues' cell walls during cooking facilitates the assimilation of this priceless ingredient by our digestive systems.
Well, cooked carrots provide beta-carotene, commonly known as carotenoids, which the body absorbs more readily. Furthermore supporting this fact is a study that was published in the Journal of Agriculture and Food Chemistry. It demonstrates how carrots' antioxidant carotenoid content is generally preserved by steaming and boiling.
The food and beverage industries commonly use beta-carotene as a natural colourant and nutrient enhancer. It imparts a seductive orange color to a wide range of meals, including dairy products, beverages, confections, and bread items.
Vitamin A megadoses may be harmful to the liver. Carotene overconsumption results in carotenemia rather than vitamin A toxicity, even though it is transformed by the body into vitamin A. Though it normally has no symptoms, carotenemia can cause carotenosis, which causes the skin to turn yellow.
Key points. Dietary changes can affect both the onset and course of cancer. Pigments in the carotenoids family have inverse relationships with cancer. Because they are powerful antioxidants, carotenoids may have protective effects.
Lastly, the metabolism and conversion of carotenoids to retinol can be slowed down in some illness situations, which can result in higher plasma levels and slower clearance. There is no guarantee that elevated serum beta-carotene levels lead to carotenosis; nevertheless, when intake exceeds 20 mg/day, the condition is more likely to manifest.
The preference for more golden or "yellow-toned" skin as a sign of health could be attributed to "carotenoid pigments," which are found in fruits and vegetables. Strong antioxidants, these plant pigments absorb harmful substances created as the body fights illness.
