Dr Robert Young writes about Carotenoids:
Carotenoids are a group of phyto-chemicals that are a powerful alkalizing weapon against dietary and metabolic acids that cause cancer. They are found in leafy green, yellow, and some white vegetables and many fruits.
Over 600 carotenoids are found in nature, 50 of which are used in the human diet. Of these, beta-carotene, alpha-carotene, beta-crytoxanthin, and gamma-carotene can be converted by the body into vitamin A. In this transformation, only the amount of vitamin A needed for health is generated, and the rest remains as the original carotenoids. For example, whether you take 10,000 IU of beta- carotene or a million, the amount of vitamin A produced in the body remains the same. This makes the carotenoids a very safe way to get your vitamin A.
Studies show that mixing some vitamin A with the carotenoids is especially beneficial for healthy white blood cells and for preventing any cancerous condition. Each of the various types of carotenoids has a different function in the body and also accumulates in different concentrations in various tissues and organs.
