I thought that carrot and red beet juice were good to go against cancer? Your thoughts would be greatly appreciated. TIA(thanks in advance)
It is true that drinking carrot juice has been a popular "alternative" treatment for cancer. The protocol involves drinking the freshly squeezed juice from 5 pounds of carrots each day, which renders about 1 quart of juice. Apparently some people have used this method with successful results, but how many used this method and died is unknown.
Normal cells can be fueled by either glucose (blood sugar) or fats. Cancer cells are different, in that they can only use glucose for fuel. Carbohydrates are converted into glucose, and the more glucose you feed them - the more the cancer cells thrive. Eliminate carbohydrates from the diet, and the cancer cells literally starve to death. This is called a Ketogenic Diet, which is useful in treating cancer, epilepsy, and many other ailments.
Carrots contain glucose and fructose in the juice, and lots more carbohydrate locked up in the cellulose fiber of the root. The juicing process does not break down the cell walls of the cellulose fiber where most of the carbohydrate (starch) is trapped, so the only sugars in a raw carrot is the glucose and fructose in the juice. Cooking a carrot causes the cellulose fiber to break down, releasing the starchy carbohydrate for conversion into glucose by the liver. So a cooked carrot, when eaten has way more calories (carbohydrate/sugars) than a raw carrot. Carrot juice actually has very little sugar, because it hasn't been cooked. Secondly, about half of the sugar in carrot juice is glucose and half is fructose. The liver immediately converts the fructose into fatty acids (triglycerides) which can be used as energy for normal cells - but not cancer cells, which can only burn glucose.
In summary, that woman expressing the opinion in the Dr. Mercola article is apparently not fully educated about the relationship between carrot juice and cancer. A raw carrot actually has about the same amount of glucose as a cucumber or a stalk of broccoli - nothing to worry about in regard to feeding cancer cells. Now, if you cook the carrot and eat the whole thing - then yes, it will have more carbohydrate than many other vegetables.
It is thought to be the beta carotene in carrots that has the anti-cancer affect, but nobody knows for sure. Kale has even more beta carotene than carrots - but moreover, Kale has more and better anti-cancer components than carrots such as sulforaphane. If I was making a vegetable juice for a cancer diet, I would make it at least half Kale juice, add 1 big carrot, 5 ribs of celery, 1 colored bell pepper. Celery is rich in a chemical called apigenin, which has powerful anti-cancer properties and the colored bell pepper is very high in Vitamin C (so is the Kale).
