Whole Grain & Bran Reduce Chronic Disease Risks

Posted Jul 31 2013 10:08pm

The current Dietary Guidelines for Americans recommends that whole grains account for at least half of the recommended 6 to 11 daily grain servings, to reduce the risk of chronic diseases. Yet, fewer than 1 in 10 Americans meets this recommendation.  Researchers with the American Society of Nutrition performed a literature review of human studies that investigated the contribution of bran or cereal fiber eon the impact of whole grains for chronic disease risk reduction.  Noting that: “Most whole-grain studies included mixtures of whole grains and foods with ≥25% bran,” the study authors report that: “Prospective studies consistently showed a reduced risk of [type 2 diabetes] with high intakes of cereal fiber or mixtures of whole grains and bran. For body weight, a limited number of prospective studies on cereal fiber and whole grains reported small but significant reductions in weight gain. For [cardiovascular disease], studies found reduced risk with high intakes of cereal fiber or mixtures of whole grains and bran.”

Tip #192 - Stay Connected
Researchers from the University of Chicago (Illinois, USA) report that social isolation may be detrimental to both mental and physical health. The team analyzed data from the National Social Life, Health, and Aging Project, a nationwide US study involving 3,000 men and women, ages 57 to 85 years. They arrived at three key findings regarding the relationships between health and different types of isolation:

• The researchers found that the most socially connected older adults are three times as likely to report very good or excellent health compared to those who are least connected, regardless of whether they feel isolated.

• The team found that older adults who feel least isolated are five times as likely to report very good or excellent health as those who feel most isolated, regardless of their actual level of social connectedness.

• They determined that social disconnectedness is not related to mental health unless it brings feelings of loneliness and isolation.

Separately, Rush University Medical Center (Illinois, USA) researchers studied 906 older men and women, testing their motor functions (including grip, pinch strength, balance, and walking) and surveying their social activity, for a period of 5 years. Those study participants with less social activity were found to have a more rapid rate of motor function decline. Specifically, the team found that every one-point decrease in social activity corresponded to an increase in functional aging of 5 years, translating to a 40% higher risk of death and 65% higher risk of disability.
