| Blood levels of many antioxidants were reduced (vitamin C by 44 percent, vitamin E by 42 percent, vitamin a by 44 percent, beta-carotene by 29 percent, and lycopene by 67 percent), presumably because they were used up by the iron-induced oxidative stress. The total antioxidant potential was reduced by 14 percent. The researchers suggested that this oxidative stress might be the cause of the myocardial damage that is the major cause of death in the disease. They concluded that administration of antioxidant compounds, but not vitamin C, could be beneficial. |

| The main fat-soluble, small-molecule antioxidants are vitamin E, various carotenes (relatives of vitamin a), lipoic acid, and vitamin Q1Q. Vitamin E is alpha-tocopherol. It has a relative—gamma-tocopherol?that is also a significant antioxidant. Vitamin E also boosts immune responses, both by protecting the membranes of the rapidly dividing immune cells in the tissues from oxidative stress and by protecting the sympathetic nerves in the lymphoid tissue, where the immune cells are formed, against oxidative stress. |

Beta carotene
Beta carotene is part of a family of plant pigments that result in the yellow, orange, and red colors of fruits and vegetables. Though over
600 carotenoids have been identified in nature, beta carotene is one of the most abundant carotenoids found in human foods. As such, it plays an important role in cancer prevention. |
| Finally the presence of alcohol causes increased movement of vitamin a from the liver to other tissues.
Alcohol also causes an accelerated breakdown of vitamin E. Since vitamin E and glutathione are required for the liver's normal detoxification processes, these nutritional deficiencies can directly lead to toxic consequences. Cell membranes are then destroyed, with one result being alcoholic liver disease.
In addition, alcohol can interfere with vitamin D function. |
| Concurrently, high intakes of zinc and vitamin a are associated with less throat cancer.
Light to moderate drinking of alcohol also slows down the burning of fats, leading to increased fat storage (probably the reason why people become overweight when they regularly drink even moderate amounts of alcohol). If moderate to light drinkers will reduce their fat intake, this can help to avoid the potential weight gain due to ethanol. Bottom line: If you drink, try to consume only low-fat foods. |

| Beta carotene is converted into vitamin a.
Bile
A green fluid secreted by the gall bladder into the small intestine. Bile acts like a soap, breaking fat into a mixture that can be absorbed into the blood. Primary bile acids can be converted by bacteria that reside in the intestine into secondary bile acids. Secondary bile acids are more toxic to the surfaces of the large intestine.
Biliary secretion
The process of bile formation in the liver and storage in the gall bladder, and finally secretion into the small intestine. Pronounced secretion of bile occurs after eating high fat meals. |
| Retinoid
A family of compounds similar to vitamin a. Saponins
Plant chemicals commonly found in legumes and other plants that are associated with reducing tumor growth and abnormal growth of cells in the colon. They are similar in structure to cholesterol. Yet they have been found to bind cholesterol and reduce its absorption.
Scirrhous carcinoma

Heroic Thinkers and Dietary Biases
Several heroic thinkers and researchers have blazed the trail past our cultural biases and preconceived notions. |
| To ensure sufficient vitamin a in your diet, eat foods such as fish, flax, and liver, which are rich in this important vitamin.
BONES ARE VERY MUCH ALIVE
Bones are living tissue. Calcium, magnesium, zinc, and other minerals are deposited and removed on an ongoing basis. Connective tissues within bones and supporting the bones are renewed regularly. This work is conducted by cells that are bone builders (osteoblasts) and cells that are bone destroyers (osteoclasts). Our bones are made up of about 25 percent water, 25 percent protein, and the rest are mineral salts, mostly calcium. |

 The body has a feedback mechanism that protects it from excess conversion into vitamin a, so that you have no worries about toxicity from carotenes.
A large body of scientific research shows that carotenes help protect against cancer and heart disease and the degeneration from free radicals. In some animal studies, they have even led to the regression of some cancers. High amounts as supplements or from food can lead to deposits in the subcutaneous fat and make your skin appear orange. This is a harmless condition known as carotenemia. |
| Also, the body produces vitamin a from beta-carotene, which is (incorrectly) called a provitamin. Some substances are not exactly vitamins, but they are like vitamins because they are part of other nutrients, such as para-aminobenzoic acid (PABA), choline and inositol.
I have been taking dietary supplements for 25 years. I take a wide variety of vitamins, minerals, amino acids, flavonoids and herbs. I usually take large doses of the most protective nutrients—I will tell you more about what I take later. You, too, can be a part of this health revolution. |
| The fat-soluble vitamins are vitamin a, beta-carotene, and vitamins D, E, and K. Coenzyme Q10 is another fat-soluble nutrient, although it is not, strictly speaking, a vitamin. Essential fatty acids are obviously fat soluble, but they are worthy of their own discussion. Certain substances, such as mineral oil, some medications, and excesses of certain fibers in the diet may reduce the absorption of fat-soluble nutrients or some minerals.
One property of some of the fat-soluble nutrients is that they may be readily stored either in fatty tissue or in the liver. |
| The FDA blatantly misrepresents the dangers of supplements when it reports to Congress that there have been deaths from vitamin a or toxicity from essential oils, which is contrary to fact.
6. It would be ridiculous in America to have restrictions on dietary supplements but ready access to alcohol, tobacco, and "Big Macs," with all their known problems.
If I could spend a half-hour with each of you, I am convinced that you would want to take at least two or three dietary supplements that the FDA has either already tried to restrict, or will without passage of S. 784. |

| An "updated prudent diet," according to Gey, should contain i mg of vitamin a, 6-15 mg of beta-carotene, 60-250 mg of vitamin C, and 60-100 mg of vitamin E supported by "plant antioxidants" [64]. Toxic levels are estimated by Van der Hagen et al. as over 150,000 IU for beta-carotene, 1 G for vitamin C, 800 mg for vitamin E, and 500 ug for selenium [221]. These authors support the use of supplements for the prevention of eye disease. |

 Beta-carotene, he remarks, mainly breaks down into vitamin a, but also into some "abnormal compounds" in tiny concentrations. These are harmless to most people, but when combined with cigarette smoke (itself the source of 200 chemicals) they may have promoted the growth of malignant cells. He concludes that "if you smoke and/or have been exposed to asbestos, you should not take supplementary beta-carotene." (335) Others would limit this restriction to the synthetic form alone.
Almost everyone agrees that natural beta-carotene in food is protective against cancer. |

 Oncologists at West Virginia Medical School randomized 65 patients with transitional cell carcinoma of the bladder into either the "one-per-day" vitamin supplement providing the RDA, or into a group which received the RDA supplement plus 40,000 iu of vitamin a, 100 mg of B-6, 2000 mg of vitamin C, 400 iu of vitamin E, and 90 mg of zinc. At 10 months, tumor recurrence was 80% in the control group
(RDA supplement) and 40% in the experimental "megavitamin" group. Five year projected tumor recurrence was 91% for controls and 41% for "megavitamin" patients. |

SAFETY ISSUES. |
| If vitamin a was the mother of all anti-cancer vitamins, then vitamin C is the grandmother of all. The problem started millions of years ago when primates lost the liver enzyme necessary to convert sugar works as a potentiator of radiation therapy. In one study, patients with mouth cancer who were pre-treated with injections of K-3 prior to radiation therapy doubled their odds (20% vs. 39%) for 5 year survival and disease free status.119 Animals with implanted tumors had greatly improved anti-cancer effects from all chemotherapy drugs tested when vitamins K and C were given in combination. |
| Oftentimes, drug companies find a substance that has therapeutic action, such as vitamin a or indole-3-carbinol from broccoli, and will try to create a slightly different molecule so that it can be patented. These slight differences nearly always translate into high toxicity from these newly-formed molecules. For instance, the difference between a man and woman rests primarily on the difference between the hormones testosterone and estrogen, which are nearly identical molecules except for one OH group. Over 40 years ago, Professor J.S. |
| Niacin, vitamin a, vitamin C, fish oil and others all reflect the fact that low dose of a nutrient will give you basic survival functions, while higher doses give us "above-vitamin" or meta-vitamin functions. In this case, vitamin K is basically a clotting factor that helps to activate prothrombin so that we do not bleed to death when cutting open the skin envelope.113 In higher doses, vitamin K becomes a potent anti-cancer agent which is non-toxic to healthy cells.114
Synergism yields two main benefits: 1) significant increase in healing capacity; 2) the need for lower doses. |

It is easy to appreciate the beauty of carotenoids on a crisp fall day with the autumn foliage at its peak. Carotenoids are usually pigmented substances produced by plants to assist in photosynthesis and protect the plant from the damaging effects of the sun's radiation. Of the 800 or so carotenoids that have been isolated, the most famous are beta-carotene, alpha-carotene, lutein, zeaxanthin, lycopene, and beta-cryptoxanthin. |
