Calcium News and Research

RSS

Calcium, the most abundant mineral in the body, is found in some foods, added to others, available as a dietary supplement, and present in some medicines (such as antacids). Calcium is required for muscle contraction, blood vessel expansion and contraction, secretion of hormones and enzymes, and transmitting impulses throughout the nervous system. The body strives to maintain constant concentrations of calcium in blood, muscle, and intercellular fluids, though less than <1% of total body calcium is needed to support these functions.

The remaining 99% of the body's calcium supply is stored in the bones and teeth where it supports their structure. Bone itself undergoes continuous remodeling, with constant resorption and deposition of calcium into new bone. The balance between bone resorption and deposition changes with age. Bone formation exceeds resorption in growing children, whereas in early and middle adulthood both processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds formation, resulting in bone loss that increases the risk of osteoporosis over time.

Zometa improves OS, PFS in newly diagnosed multiple myeloma patients: Phase III study

A newly published study in the Lancet suggested that a first-line treatment regimen including Zometa (zoledronic acid) significantly improved overall survival and progression-free survival in newly diagnosed multiple myeloma patients compared with a regimen that included oral clodronate. The impact on survival was independent of the effect of Zometa on bone complications (also known as skeletal-related events or SREs).

Experts reach consensus on beneficial effects of Soy

According to the December 2010 Journal of Nutrition Supplement titled, "Soy Summit: Exploration of the Nutrition and Health Effects of Whole Soy," consensus has been reached among leading soy science experts surrounding three main areas of debate: soy and women's health, soy and heart health, and soy and overall nutrient adequacy. Leading soy experts agree that including soyfoods in a balanced diet will have beneficial effects and improve nutrient intake among the U.S. population.

Mushrooms are good source of vitamin D

The Institute of Medicine (IOM) recently released the results of its 24-month review on dietary reference intakes (DRIs) for vitamin D and calcium, which validated the importance of vitamin D as an essential nutrient for promoting bone health. The committee set the recommended intake level at 600 IU, which is triple the previously recommended amount from 1997.

IOF commends IOM's new vitamin D and calcium intake recommendations

On November 30, 2010, the Institute of Medicine of the National Academy of Sciences (IOM) in the US released new recommendations on daily reference intakes for vitamin D and calcium across all ages. The report is based on available evidence in the literature, with higher quality studies, supporting the role of these nutrients on bone health. Vitamin D deficiency is an important health issue to address as it has been linked to the pathogenesis of osteoporosis and hip fractures as well as other skeletal and non-skeletal disorders.

CRN says increased DRI for vitamin D a step in right direction, but still falls short

The Council for Responsible Nutrition (CRN), the dietary supplement industry's leading trade association, today called the National Academy of Sciences Institute of Medicine's (IOM) newly released report on the Dietary Reference Intake (DRI) levels for vitamin D "a modest step in the right direction that fell short of truly capturing the extensive and positive research that has consistently supported the need for people to significantly raise their vitamin D levels."

Study finds link between osteoporosis and cardiovascular disease

Norwegian studies indicate that people with osteoporosis have a greater risk of developing cardiovascular disease, and vice versa. Now researchers believe they have found a biological system that may influence both disease processes.

Vitamin D supplementation may reduce risk of diabetes, heart disease: Research

Researchers from the UC Davis Health System have found that compared with healthy controls, blood levels of vitamin D are significantly reduced in patients in the Sacramento area with metabolic syndrome, a constellation of disease risk factors that affects about one in three U.S. adults and predisposes them to diabetes, heart disease and stroke.

Are vitamin D and calcium supplements needed?

The IOM raised the recommended dietary allowance of vitamin D from the amount cited in their last report, released 13 years ago. It said that although 600 international units (IUs) of vitamin D or more each day is sufficient to maintain bone health in majority. But those aged 71 and older may need as much as 800 IUs daily, the IOM experts say. However 1997 recommendations advised 400 IUs per day for people aged 51 to 70 and 600 IUs per day for those over 70.

Majority of Americans and Canadians are getting enough vitamin D and calcium, says report

The majority of Americans and Canadians are getting enough vitamin D and calcium to meet their needs, says a new report from the Institute of Medicine. Most people up to age 70 need no more than 600 international units, or IUs, of vitamin D per day, and those 71 and older may need as much as 800 IUs, the report finds. The amount of calcium needed ranges, based on age, from 700 to 1,300 milligrams per day.

Molecular switch plays crucial role in addictive behavior and memory processes

Learning and memory formation are based on the creation of new connections between neurons in the brain. Also, behaviors such as nicotine addiction manifest themselves in long-term changes of neuronal connectivity and can - at least in this respect - be viewed as a form of learning.

IOM report updates DRIs levels of Vitamin D, calcium

Vitamin D and calcium have been the focus of much research since the Institute of Medicine set nutritional reference values for them in 1997. Known as Dietary Reference Intakes, the values for these and other nutrients serve as a guide for good nutrition and provide the scientific basis for the development of food guidelines in both the United States and Canada. Updated DRIs for these two nutrients are presented in a new IOM report, Dietary Reference Intakes for Calcium and Vitamin D, which will be released on Tuesday, Nov. 30.

Spray-on organic/inorganic films

Coatings functionalize surfaces or protect them from processes such as corrosion, abrasion, and weathering, and may provide an aesthetic appearance—automotive coatings and non-stick frying pans are good examples. Contact lenses, implants, LEDs, or photovoltaic cells require extremely thin coatings. In the journal Angewandte Chemie, the teams led by Gero Decher at the Institut Charles Sadron in Strasbourg (France) have now introduced a new process for the production of ultrathin coatings that is especially simple, versatile, and suitable for large-scale processes.
