Supplemental vitamin D may reduce the risk of certain cancers

Supplemental vitamin D may reduce the risk of certain cancers

Researchers suggest that improving vitamin D status could reduce cancer incidence and mortality. Since it is difficult to get adequate vitamin D from foods alone, scientists suggest that a vitamin supplement may help raise vitamin D intakes to protective levels.


A recent published report concluded that vitamin D deficiency may account for several thousand premature cancer deaths annually.

The research team reviewed 63 studies on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer, especially in cancers of the colon, breast, prostate and ovary.

Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units (I.U.) a serving. Researchers suggested that people might want to consider a vitamin supplement to raise their overall intake to 1,000 I.U.s per day.

Taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.

High glycemic index diets increase the risk of chronic degenerative disease

High glycemic index diets increase the risk of chronic degenerative disease

Long-term consumption of high-glycemic foods may increase oxidative stress and the risk of chronic degenerative diseases. Leading U.S. researchers recently concluded that a low-GI diet, not a low carbohydrate diet, appears to be beneficial in reducing the production of free radicals and oxidative stress.


Glycemic index (GI) is a measure of the rate that the carbohydrates in a food or meal are digested and appear in the blood as glucose (sugar). Glycemic load is a way of measuring the total carbohydrates in a meal or diet with a mathematical adjustment for GI. These measurements can be used to simultaneously describe the quality (glycemic index) and quantity of carbohydrate in a meal or diet.

Recent data suggest that the sudden rise in blood sugar associated with a high glycemic load may increase free radical production and the risk of oxidative damage. This increased production has been implicated in many disease processes including chronic heart disease, accelerated aging, and type 2 diabetes.

Investigators from several leading U.S. institutions recently investigated whether a diet with a high GI or GL is associated with greater oxidative stress by taking specific measurements in nearly 300 healthy adults.

Participants with a higher GI and GL diet were found to exhibit increases in oxidative stress when compared to those eating a diet lower in glycemic index and load.

Researchers concluded that chronic consumption of high-GI foods may lead to chronically high oxidative stress, increasing the risk for several degenerative diseases. A low-GI diet, not a low carbohydrate diet, appears to be beneficial in reducing oxidative stress.

USANA Recognized for Best Dietary Supplements Category

USANA Health Sciences was recently recognized for producing the best dietary supplements in the state of Utah at the "Best of State" awards gala held on Saturday, June 24.

Recognition as the best "dietary supplement company" in the state of Utah is especially meaningful because of the numerous supplement manufacturers located here. According to the Utah Natural Products Alliance, Utah has between 80-100 dietary supplement companies with sales of more the $2.5 billion, and USANA Health Sciences has now been officially recognized as "Best in State."

This award reflects the commitment Dr. Myron Wentz made more than ten years ago to create the world's finest nutritionals. It is also a result of USANA's voluntary compliance to pharmaceutical GMPs, to our industry-leading Potency Guarantee and to sound science in every formulation.

Once again USANA has shown that its dietary supplements are the industry standard!

Dr. DeLaCruz Offers Free Medical Services in Dominican Republic*

Dr. DeLaCruz Offers Free Medical Services in Dominican Republic*


Dr. Francisco DeLaCruz was recently able to return to the place of his birth, the Dominican Republic, to perform free medical services for many impoverished citizens in the area. This mission to the Dominican Republic is a dream that Dr. DeLaCruz had awaited for many years to become a reality.

Fran was able to accomplish this dream, due in part, to his USANA business. By August of 2005, he dropped his medical schedule down to a part-time status working just seventeen weeks a year. Soon after this, Fran discovered an organization called Children of the Nations that organized teams of medical professionals to offer free medical services in third world countries.

After learning that the Dominican Republic was on their list of countries to visit, Fran signed up for the next trip. Fran flew down with three other physicians and a crew of technicians. Fran explains, "It was everything I imagined it would be and more. We did thirty-one surgeries—burns, facial trauma, general surgery—and all the medical care was provided for free. There were people who walked thirty miles to get their surgical procedure done."

Fran encourages other network marketers to use their time freedom to seek out non-monetary rewards. "My dad came to the United States because of the opportunities. I'm glad that I can now take some of what we gained here back to my people in the Dominican Republic"

Soy isoflavones benefit the immune system of postmenopausal women

Soy isoflavones from supplements and soymilk benefit the immune system of postmenopausal women

The hormone estrogen has positive benefits on the immune system of women. During menopause, the effects of aging and diminishing concentrations of estrogen may negatively impact the immune system. Soy isoflavones have both estrogenic and antioxidant properties so they may be beneficial to women during this stage of life.


A recent study evaluated the effects of soy isoflavones, both in soymilk and supplement form, on immunity and oxidative stress in postmenopausal women. Results from this placebo-controlled double blind study showed that soy isoflavones from either the soymilk or supplements were beneficial. Isoflavones increased the population of B-cells, important cells in the immune system, and decreased the plasma concentration of a compound whose high levels are an indicator of DNA damage.

Soymilk and supplemental isoflavones may therefore be protective against DNA damage and improve immune function in postmenopausal women.

Higher Antioxidant Intakes Reduce Risk of Lung Cancer in Male Smokers

As usaul I like to give you information on Health issues that concern our USANA home business.

Don't avoid antioxidant supplements if you are a smoker or former smoker. Research in the 1990's seemed to indicate that high dosages of beta-carotene supplements may increase lung cancer risk in smokers. However, a new analysis of dietary records from one of these studies came to a different conclusion. Male smokers with the highest overall antioxidant intake, including beta-carotene, actually had a reduced risk of lung cancer.



In observational studies, a high intake of individual antioxidants was related to increased lung cancer risk in male smokers. However, data from many experiments suggest that there are interactions among antioxidant nutrients; therefore, consideration of multiple antioxidants simultaneously may be important in terms of assessing risk.

Yale University researchers evaluated dietary records of participants in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC). A group of over 27,000 Finnish male smokers aged 50-69 had food records analyzed along with intakes of carotenoids, flavonoids, vitamin E, selenium, and vitamin C. After evaluating the overall intake of antioxidants in this group, the conclusion differs somewhat from the original study.

According to this new analysis, the men with higher overall intakes of antioxidants had lower relative risks of lung cancer, regardless of their assigned study group (beta-carotene or placebo). While researchers of the ATBC study concluded that high-dose beta-carotene supplementation may increase lung cancer risk in male smokers, these findings support the hypothesis that a combination of dietary antioxidants reduces lung cancer risk in men who smoke.
