Long-term use of a daily multivitamin/mineral may lower cancer risk in middle-aged and older men

Note: Separate pills are better to take as all in the same pill cancels out good effects. This is a subtley important to understand.

A large study published in the Journal of the American Medical Association, using data obtained from the Physicians' Health Study II, has found that the use of a daily multivitamin/ mineral supplement long term can reduce the risk of cancer occurrence.

In this randomized, double-blind, placebo controlled study of approximately 14,641 male physicians ages 50 or older from the United States, participants were randomly assigned to take a daily multivitamin/ mineral supplement or a placebo between 1997 and June 2011. During the median follow-up of 11.2 years, researchers recorded 2,669 cancer cases, including 1,373 prostate cancer cases and 210 colorectal cancer cases. When examining outcomes at the study's end, the researchers found an 8 percent reduction in total cancer occurrence among participants assigned to multivitamin use.

Although the main reason to take multivitamins is to prevent nutritional deficiency, this study reinforces the value of long-term consistent use of a daily multivitamin as a convenient and affordable insurance policy for good health and possible cancer prevention in middle-aged and older adults.

Moderate soy intake not related to a negative breast cancer prognosis - Weekly Essentials of Health by Usana Health Sciences

Moderate soy intake not related to a negative breast cancer prognosis - Weekly Essentials of Health by Usana Health Sciences

Recent epidemiologic studies report no adverse effects of soy foods on breast cancer survival or prognosis.

Contrary to earlier clinical studies and some popular media suggesting that soy may promote breast tumor growth, three recent studies show that moderate intakes of soy-containing foods are not adversely related to breast cancer prognosis.

In the most recent study researchers used data from the Women’s Healthy Eating and Living (WHEL) study to examine the effect of soy intake on breast cancer prognosis. Soy isoflavone intake was assessed in 3,088 breast cancer survivors diagnosed between 1991 and 2000. After an average follow-up of 7.3 years, it was found that as isoflavone intake increased, risk of death decreased. Women whose intake was >16.3 mg of isoflavones had a 54% reduction in the risk of death.

This is the third recent epidemiologic study to report no adverse effects of soy foods on breast cancer prognosis. Because these studies varied by ethnicity and the level and type of soy consumed, the investigators stated that when taken together, these studies provide evidence to suggest that it may not be necessary for clinicians to advise against moderate soy consumption for women with a diagnosis of breast cancer.

The following is a summary of a previous Essentials of Health from Jan 27, 2010. Also included are two more recent study references with similar outcomes.

“In a large prospective study of female breast cancer patients treated surgically, moderate soy intake was associated with a significant decrease in death and cancer recurrence during a 4 year follow-up. Women whose intake of soy protein was among the top 25 percent of participants had a 29 percent lower risk of death during follow-up and a 32 percent lower risk of recurrence compared to those whose intake was in the lowest quarter.  This study suggests that moderate soy food intake is safe and potentially beneficial for women with breast cancer.”
