Study reveals how carrots are healthy for heart

New York, Dec 12 : Carrots are a good source of beta-carotene, which is a precursor of vitamin A and to get the full health benefits of this superfood, we need an active enzyme to produce this vitamin, say researchers.
Beta-carotene is the bioactive compound that gives carrots their orange colour. Studies with humans and mice show the conversion of beta-carotene to vitamin A reduces “bad” cholesterol in the blood.
“Thus, beta-carotene can help protect against atherosclerosis development, which leads to the accumulation of fats and cholesterol in our arteries. Atherosclerosis cardiovascular disease is the primary cause of death worldwide,” said study author Jaume Amengual from the University of Illinois in the US.
The research team conducted two studies to further understand the effects of beta-carotene on cardiovascular health. They confirmed its importance but identified a critical step in the process.
Beta-carotene converts to vitamin A with the help of an enzyme called beta-carotene oxygenase 1 (BCO1).
“A genetic variation determines if you have a more or less active version of BCO1. People with a less active enzyme could need other sources for vitamin A in their diet, Amengual said.
