Calcium supplement warning from scientists

Calcium supplements linked to cancer in major study

From the evidence gathered, it's becoming more clear that "the regular use of dietary supplements is not beneficial in reducing the risk of mortality among the general population in the USA", according to study co author Dr. Fang Fang Zhang, an associate professor at the Freedman School of Nutrition Science and Policy at Tufts University. These deaths included 945 deaths from cardiovascular disease and 805 deaths from cancer. Dietary intake of nutrients from foods was assessed using 24-hour dietary recalls.

Too much intake of calcium from supplements is associated with an increased risk of cancer death.

The study also highlighted the negative effects of overuse of supplements: For example, getting 1000mg per day of calcium in pill form was linked to a 62 percent increased risk of cancer.

Instead, the team found indications that use of vitamin D supplements by individuals with no sign of vitamin D deficiency may be associated with an increased risk of death from all causes including cancer.

While it might be easy to blame people for being lazy and wanting the convenience of a pill over the more complicated nuances of eating a well-balanced diet, I am not sure it's that straightforward.

Taking excessive Calcium as supplements to your body may increase the risk of cancer and other deadly diseases, according to scientists.

Dietary supplements don't lengthen life and may shorten it if taken at extreme ranges, researchers reported Monday within the Annals of Inner Medication. "It is important to understand the role that the nutrient and its source might play in health outcomes, particularly if the effect might not be beneficial".

I think prior to the season I said it's a different person so it was going to be a new and different challenge. The difference appears to have its roots in two very different driving styles. "I think he's a good kid".

When considering nutrient intake alone and the associated risk of death, researchers found that adequate intake of vitamin K and magnesium were linked to lower mortality risk, and adequate intake of vitamin A, vitamin K, and zinc were linked to a lower risk of CVD mortality.

High levels of calcium intake through supplements was associated with a greater risk of death from cancer. One last advice, focus on taking as a supplement only the calcium or the minerals that are missing from your diet. While certain nutrients may contribute to a longer life, they need to come from a food source, the study found.

To calculate the daily supplement dose of each nutrient, the frequency and the product information for ingredient, amount of ingredient per serving, and ingredient unit were combined.

There was also a lower risk of cardiovascular disease (CVD) mortality when adequate intakes of vitamin A, vitamin K, and zinc were sourced from food over dietary supplements.

Professor Hugh Montgomery, of UCL Institute Human Health and Performance, said: 'The growing message is routine vitamin supplementation offers little if any benefit to health and may cause harm.

'Furthermore, there are those who eat poor quality diets but take a supplement as an insurance policy.

'Meanwhile, it is clear diets high in these components are healthy.
