Carotenoids are natural pigments that produce colours ranging from yellow-orange to red-violet in their free state.
In the human diet, around fifty different carotenoids are consumed relatively frequently. This provides us with enough vitamin A, an essential vitamin that plays a key role in vision, the immune system, and preserving epithelial tissue. Carotenoids are also powerful antioxidants that protect our cells from damage caused by free radicals, thereby helping to prevent a certain number of degenerative diseases.
Analysing blood concentrations of carotenoids allows you to measure not only how many fruits and vegetables your patients consume, but also their ability to digest and absorb lipidic substances since these molecules are hydrophobic by nature and are absorbed along with lipids.
