November Health Show: The Benefits of Calcium
from Jana Mitcham
November 15, 2005
Calcium has long been touted for its benefit to building strong bones and teeth ? even to benefiting the health of those suffering with osteoporosis. Now there is evidence that calcium consumption might be useful when fighting another potentially deadly foe. Read what Meme Groseth (MG) and Tom Mitcham (TM) had to say about this research on the November Health show conference call:
MG: Tom are you there?
TM: I sure am Meme, and like Jana, I can't wait to give that free product. Tonight's free product is Vitamin C Chewable! We wanted to continue to help our affiliates build their cold and flu arsenal.
MG: That is terrific news especially (as you mentioned) with Cold and Flu season approaching it will be good to have Vitamin C's ability to support immunity, fight viral invaders, neutralize free radicals and support the cardiovascular, respiratory, reproductive and circulatory systems. And you can get it free tonight by answering the questions or sharing a testimonial later on or as your November AutoShip product.
Tommy, let's give that free product!
TM: You bet!
QUESTIONS/ANSWERS (Q and A not recorded.)
MG: Congratulations to Suzie and our winners tonight. I know you will benefit from your Vitamin C ? especially during this Cold & Flu season.
MG: Tom is going to share some really great information about Calcium tonight. As he is sharing this information, it is important to keep in mind that he is not making a claim that any Vitamark product provides a cure, treatment or prevention for cancer. He is simply providing educational insights into certain studies (as reported by Health Sciences Institute) that point out that Calcium intake "may" be a preventive for colorectal cancer.
TM: Wow, Meme, with a lead-in like that, I hate to delay; but I will because I'd like to start with product testimonials! Who'd like to be first?
MG: Yes, who would like to be first and get some free Chewable C?
Start by identifying yourself, we want to get your name right.
TESTIMONIALS (Testimonials not recorded.)
MG: Thanks for sharing! Now for that exciting information:
TM: Before starting with tonight?s information on Calcium I'd like to share some more exciting research on Probiotics. We discussed Probiotics and their impact on Cold & Flu season on last month's Health Show. Since that call Jana has discovered research that says Probiotics is good for children with skin concerns. Remember our intent is not to make a claim for any products ability to cure, treat or prevent any disease ? it is to educate you about what is happening in research. The new study further verifies a previous study done at University of Helsinki on the merits of probiotics on dermatitis (a skin eruption) in children. The new Australian study was done at University of Western Australia in Perth on 53 children between the ages of 6-18 months. Twenty-seven were given 1 billion cfu of probiotics twice a day for 16 weeks while the others received a placebo. The doses were given in a water mix. The children tested had a score of 25 (indicates severe) or more on the Severity Scoring of Atopic Dermatitis (SCORAD) Index. A European Task Force made up of more than twenty dermatologists developed the index. At the end of the test, 92% of the group receiving the probiotics scored better on the SCORAD. They reported a reduction of symptoms with 54% dropping from severe to mild. Further indication that a healthy level of good bacteria in your gut is necessary for overall good health.
MG: Thanks for that update. I imagine if it impacts babies, it probably would impact adults. It certainly can't hurt. I would like to challenge anyone on the call with skin concerns to add Probiotics to your daily regimen and just see what happens. Now Tommy, why don't you share with us.
TM: I want to remind everyone of what Meme said before starting: The content of tonight's show is not intended to be a claim for any Vitamark products; it is simply to educate you about some recent research which states: Calcium intake "may be" ?a powerful preventive against colorectal cancer.
MG: Tom, that's a bold statement, but with study after study on the subject we're beginning to see evidence mounting.
TM: We surely are like the research at the Dartmouth Hitchcock Medical Center which showed how high calcium intake may significantly lower the risk of advanced polyps developing into cancer. That study indicated that calcium supplements (apart from dietary sources) provide effective protection against advanced polyps.
MG: I understand that now a new study from the University of Minnesota confirms those earlier results, while shedding new light on the value of supplementing with calcium.
TM: Yes, there is, ?but as we'll see, there are important guidelines that everyone who uses calcium supplements needs to be aware of.
This is a significant study due to its large population group. Researchers at the University of Minnesota (UM) used data collected from more than 45,000 women who completed National Cancer Institute food frequency questionnaires. None of the women had a history of colorectal cancer at the outset of the study.
MG: I imagine they had to establish some strict guidelines.
TM: They certainly did. In addition to tracking dietary sources of calcium, the researchers separated the subjects into four groups according to their intake of supplementary calcium:
- Zero calcium supplement intake: more than 25,400 subjects
- Zero to 400 mg daily: more than 9,400 subjects
- 401 to 800 mg daily: more than 4,100 subjects
- More than 800 mg daily: more than 6,200 subjects
Diet, supplement intake and medical records were followed for an average of 8.5 years. During that time, 482 women developed colorectal cancer.
MG: The results were published in the January 2005 issue of Cancer Epidemiology, Biomarkers and Prevention, the UM team reported three key results:
- Compared with low calcium consumption (from either diet or supplements), subjects who consumed between 400 and 800 mg of calcium per day from any source reduced their risk of colorectal cancer by about 25 percent
- When calcium intake was more than 800 mg per day, colorectal cancer risk was reduced by more than 45 percent
- Women who consumed large amounts of calcium from both dietary and supplemental sources had the greatest protection against colorectal cancer.
TM: Very impressive numbers. These results, combined with earlier research (such as the Dartmouth-Hitchcock trial of more than 900 men and women), would indicate that high calcium intake also acts as a preventive against colorectal cancer in men.
Both the UM and Dartmouth-Hitchcock studies illustrate the importance of including plenty of calcium-rich foods in your diet, such as salmon, cabbage, kale, and yellow, green, or waxed beans.
MG: Yes, dietary sources are important but we know that food sources may not provide enough and that supplementation may be necessary. In the Dartmouth-Hitchcock study, subjects also took 1,200 mg of calcium carbonate daily. Calcium Carbonate binds the most acid, a potential plus. Some scientists believe that calcium's ability to bind acids may be the very reason it protects against cancer. It's ability to bind acid is also one reason it helps maintain the critical acid/alkaline balance in the body.
TM: Another important thing to remember about calcium is that [according to Dr. Alan Spreen] "Calcium is not found in nature (in edible form) without magnesium, and they therefore should always be given together."
Foods that are high in calcium and magnesium include leafy green vegetables, whole grains, bananas, apricots, meat, beans, and nuts.
Remember, a good quality Calcium supplement will include certain ?helping nutrients" like Magnesium and D3. These nutrients help the body better utilize and absorb the Calcium. Always demand the best from your dietary supplements and you will achieve optimum benefit.
MG: Thanks for sharing with us about another possible benefit for Calcium supplementation. Of course we all know how important Calcium is to the health of our bones, joints and teeth. It certainly is essential to your overall good health and should be a part of everyone's daily regimen.
TM: I couldn't agree with you more Meme. Before we go, I'd like to mention one other important piece of the puzzle to prevent colorectal cancer. This preventive measure is, of course, colonoscopy. Ask your doctor about arranging for a colonoscopy, which is recommended every three to five years for everyone over the age of 50; especially those with a family history of colon cancer.
MG: Thanks for sharing this valuable information with us.
TM: Good night everyone! Remember this is the day the Lord has made ? rejoice and be glad in it!
