Vitamins Not Preventing Cancer in Women, Says Study

Vitamins aren’t all they’re cracked up to be. A recent study shows that vitamins C and E do little or nothing to prevent cancer in women. Between the years 1995 and 1996 until 2005, a group of 8,171 women over 40 were given a combination of vitamins and placebos to determine whether or not the supplements had any effect against cancer. They didn’t:

The supplements were vitamin C (500 milligrams a day), vitamin E (600 International Units every other day) and beta carotene (50 milligrams every other day).

The women, all over the age of 40, took part in the study from 1995 and 1996 until 2005, for an average of nine years. They all had cardiovascular disease or were at risk for it.

A total of 624 of the women developed cancer, and 176 died from it during the period of the study. The researchers didn’t find any "statistically significant" evidence that the supplements either helped or hurt a woman’s risk of developing cancer.

Despite these findings, which were published in the Journal of the National Cancer Institute, researchers insist further studies need to be done. They also hypothesize that previous studies about the effectiveness of vitamins may have shown they prevent cancer because subjects were malnourished. Thus, a healthy diet of foods rich in antioxidants — like fruits and vegetables — can still help prevent cancer.

There’s also another caveat: All of the women in the aforementioned study either suffered from cardiovascular disease or were at risk. Women who are not at risk may find vitamins more beneficial. What’s more, vitamin E may help specifically prevent colon cancer, which is a seriously aggressive breed of the baddie.

So, while it may be tempting to toss your bottles, it doesn’t hurt to keep popping pills. You know, just in case …

Carmel Just to add to your great list. I used to take Indole 3 Carbinol after my first go round with breast cancer. It is a derivative of the component in crutaceous vegetables (branching veggies like broccoli, kale, parsley etc), they have now discovered that the Indole 3 carbinole was not decreasing but increasing chance of breast cancer. It had to be processed further into DIM-plus or Diindolylmethane which is proving to be extremely effective in fighting breast c. A must take for Breast c survivors because it is an estrogen detoxifier. Another great fighter of breast cancer is Co-enzyme Q10, except you have to take 380mg daily. Studies have shown it kills breast cancer cell. Also helps the heart and energy and protect the cells against aging. CoQ10 is also a cholesterol antioxidant. Grape seed extract is another antioxidant that has proven an effective preventative of breast cancer One tangerine a day has enough bioflavanoids to help prevent breast c. Yams, not sweet potatoes, are the choice to prevent breast c. Yams have a bioflavanoid that prevents it. Sweet potatoes raise the glycemic index level too high, which the body reacts with by creating insulin, which when not digested turns to fat which creates too much estrogen Very important is Calcium D-Glucarate, it detoxifies estrogen in the liver. Just like there is beneficial and unbeneficial cholesterol, there is beneficial and unbeneficial estrogen, so the calcium d-glucarate detoxifies that. Organic is always best, and if more women demanded organic from the grocer, the farms would respond. Pesticides are estrogen based, unbenificial estrogen. Many people tolerate them and it is not big deal, but we are the estrogen receptors, and some women are affected by them There are more new discoveries every day and a myriad of antioxidants that work. It is best to take a general antioxident where you get a panel of a few that will help keep you chugging along. They all work like a team. If you take turmeric with your antioxidants it keeps them fresher in your system and they work better. Vitamin C and Vitamin A or a panel of Beta Carotenes have more benefits than as breast cancer prevention, they are great for skin, hair, lungs, sinuses, and much much more.

What do you eat to get a sweet disposition?

Pills, pills, pills. I’m really concerned about this. Chemicals are now the solution to all life’s ills. Whatever happened to simply living a healthy, centered, balanced life? Eating right, exercising, avoiding smoke and limiting alcohol.

Taking vitamin supplements may not be wise. It is better to satisfy nutritional needs with foods, as a healthful diet provides the proper balance of vitamins and minerals. Some studies have shown that taking supplements can actually increase cancer risk. A recent one on the effects of vitamin E supplementation on prostate cancer risk found that taking it in pill form may have slightly increased the risk for this disease. The American Institute for Cancer Research did an analysis of all the studies on vitamin supplements and cancer, and their recommendation is to eat a diet rich in whole grains, fruits, and vegetables to get the necessary vitamins and minerals — as well as other cancer-fighting chemicals. There is considerable evidence that a healthy lifestyle — including a healthful diet — can reduce breast cancer risk and recurrence. www.ReduceBreastCancerRisk.com Getting enough vitamin D is important for women because deficiencies in this vitamin have been associated with breast cancer risk. Sunlight and fortified foods are the best source of this vitamin, and there is some in eggs and some fish.

You can do everything right but genetics will still win. I have Crohn’s disease; so far three genes have been identified with this disease. I got it when I was a robust twenty (average age of onset.) My parents owned a produce market and everything we ate was fresh. My mother was an amazing cook and nothing came out of a box. But I can trace Crohn’s back to my maternal grandmother, who’d be one hundred thirty four if she were alive. I have eleven relatives who have it. My mother didn’t, and lived to a healthy ninety four. She did do everything right. It is maddening to me that I take such good care of myself contrasted to my friends and deal this and another genetic autoimmune disease. My close friend has the Braca gene and survived ovarian cancer but also decided to have a preventative radical mastectomy. The great Sir William Osler said,” Get a chronic disease, take care of yourself, and you will be healthier than those around you.” So I’m the healthiest sick person around. I worked as a medical editor for ten years and I do see a state of the art nutritionist who’s husband is a brilliant research immunologist. I do take essential oils; I was in an NIH study years ago and the one I take can be bought in the drugstore but is considered a pharmaceutical grade. I write this in hopes that the people you know should not be “blamed” for their illnesses. I’ve gotten a lot of that from friends who smoked, were obese, etc.

your condition,and the many like it, show that “life programming” is a fact. We are genetically and environmentally programmed. In other words, we live out a play that someone else wrote.

I’d like to add some of my smoking obese friends are starting to suffer from diabetes, heart disease, etc. Also, for anyone who has Crohn’s disease or ulcerative colitis, CCFA.org is a great website. That’s the site of the Crohn’s and Colitis Foundation of America.

Eating right and taking suppliments keeps your imune system working property which helps you fight all disease. I have taken regular daily vitimin plus calcium for years and seldom get even a cold. It may not cure it but it can prevent it! What is the harm!

In moderation, likely no harm. But a few years ago they learned that Vitamin A in excess, as little as 3000 I.U., can contribute to the bone thinning of osteoporosis. See http://ods.od.nih.gov/factsheets/vitamina.asp

i would be interested in who sponsored the study, I’ve had some issues with my heart recently and told the doctor I’ve been trying to add more Omega 3 oil to my diet and she tried to give me a “new” prescription, which would cost me $36 for capsules of Omega 3 oil monthly just discovered by some drug company with posters all over her office, yeah right!

It was an NIH grant, but the Omega 3 supplement I take are made by Theratears and cost me about $13 a month. I order them from drugstore.com and get a discount and free S&H. This is the supplement the doctor who sponsored the study told me she takes. They are with the tears for dry eye in the drugstore, not with supplements. I have noticed a difference in my hair and skin, so I also consider it a beauty regimen!
