An hypothesis is presented that is opposed to the conventional viewpoint that β-carotene is an in vivo free-radical scavenger. It is suggested that there are biochemical reasons why β-carotene, other carotenoids, and especially their metabolites may be harmful to mammalian systems. Finally, the...
Intervention trials with supplemental beta-carotene have observed either no effect or a harmful effect on lung cancer risk. Because food composition databases for specific carotenoids have only become available recently, epidemiological evidence relating usual dietary levels of these carotenoids with lung ca...
Carrots are a treasure trove of essential nutrients that contribute to optimal health. These vegetables are particularly known for their high content of beta-carotene, a pigment that gives them their bright orange color. Beta-carotene is a precursor to vitamin A, a vital nutrient for maintaining ...
When you eat foods with fat-soluble vitamins, it goes through the digestion process. When it gets to the small intestine, the fat-soluble vitamins are released. Unlike water-soluble vitamins that go directly into the bloodstream, fat-soluble vitamins are absorbed through the intestinal wall and ...
There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄红素)which gives tomatoes and red peppers their red color - and beta-carotene found in carrots as well as broccoli, squash, and spinach. Skin color is also affected by chemicals called polyp...
The high levels of beta-carotene and other antioxidants in carrot juice help improve heart health by preventing the formation of harmful plaque deposits in the arteries. Carrot juice also helps improve blood circulation, which can also help protect the heart from damage. ...
Lycopene and beta-carotene are very similar and so they are implying that lycopene is harmful. The research though was not published and so other antioxidant researchers are not convinced by the argument. No doubt there will be plenty of further research into this molecule. Formal Chemical Name...
Sweet Potatoes: Loaded with beta-carotene, sweet potatoes are converted into vitamin A in the body, promoting the production of sebum for a moisturized scalp. Eggs: A fantastic source of protein and biotin, eggs provide the building blocks necessary for strong, healthy hair. Avocado: Full of ...
Spinach – Its health benefits are wide known due to the high amount of calcium, vitamin A, C, and beta-carotene. According to a research in Sweden, the nitrates in spinach reduce the amount of oxygen needed for energy. After consuming spinach, the muscles are more efficient and require le...
For instance, we get 1% of beta-carotene from carrots when eaten because of the indigestible fibers they contain, but when we drink carrot juice, we can get almost 100% of it. The enzymes are also found in fresh fruit and vegetable juices. Because heat destroys enzymes, it is very impor...
