Lower risk of disability with greater fruit, vegetable and dairy intake
Denise K Houston PhD and colleagues at Wake Forest University Baptist Medical Center evaluated data from 9,404 participants in the Atherosclerosis Risk in Communities study. The subjects were between the ages of 45 and 64 upon enrollment and were followed for an average of 9 years. Food frequency questionnaires provided the researchers with information on the amount and type of food consumed. At the end of the study, participants were surveyed on their ability to perform 12 activities of daily living as an assessment of disability, and lower extremity function was evaluated.
Participants who consumed the most fruits, vegetables and dairy products (3 servings each of fruits and vegetables and 2 of dairy) were found to have a lower risk for functional limitations that precede disability than those whose intake was the lowest (one or fewer servings of fruits and vegetables per day and less than ½ serving of dairy). The finding was particularly striking in African American women whose intake of these foods was high, who experienced a 30 percent lower risk of disability than those whose intake of fruits, vegetables and dairy was among the lowest.
Dr Houston commented, "We know that obesity, lack of physical exercise, alcohol consumption and smoking are modifiable risk factors for disability, but little is known about the role of diet. Getting the recommended number of servings of dairy, fruits and vegetables should be investigated for its potential to reduce the prevalence of disability in the aging population."
The study is the first to report an association between the intake of certain foods and the (lowered) risk of disability. The authors explained that the calcium and vitamin D in dairy foods could decrease disability risk associated with lowered muscle strength and osteoporosis, and the antioxidants in fruits and vegetables could slow age-related disability and the risk of chronic disease by reducing the accumulation of oxidative damage in tissues.
Mainstream medicine has relied on simple measures of preventing disease, such as controlling hypertension, yet many doctors are coming to the realization that additional steps can be taken to protect against premature aging and death.
In fact, the results of tens of thousands of scientific studies make it abundantly clear that following the proper lifestyle can add a significant number of healthy years to the average person's lifespan.
The premise of taking actions to maintain youthful health and vigor is based on findings from peer-reviewed scientific studies that identify specific factors that cause us to develop degenerative disease. These studies suggest that the consumption of certain foods, food extracts, hormones, or drugs will help to prevent common diseases that are associated with normal aging.
In the April 9, 1998, issue of the New England Journal of Medicine, an editorial was entitled "Eat Right and Take a Multi-Vitamin." This article was based on studies indicating that certain supplements could reduce homocysteine serum levels and therefore lower heart attack and stroke risk. This was the first time this prestigious medical journal recommended vitamin supplements (Oakley 1998).
A problem overlooked by most doctors is that loss of bone density is associated with deficiencies of not just calcium, but a host of other nutrients including magnesium and vitamin D3. In order for calcium to prevent bone loss, adequate amounts of vitamin D3, zinc, manganese and other nutrients should be available so that calcium, magnesium, and phosphorus can be incorporated into the bone matrix. Another issue that many people are not aware of is that many forms of calcium do not absorb particularly well.
In order to overcome the impediments that preclude aging women from achieving optimal calcium status, a mineral formula has been designed that provides 1200 elemental milligrams of a new highly absorbable form of calcium per daily dose, along with critically important nutrients needed to protect bone density. Bone Restore™ provides calcium along with nutrients like boron and silicon to further boost the body’s ability to maintain healthy bone density.
Just one softgel capsule of Life Extension Super Booster provides important nutrients such as gamma-tocopherol that are lacking in multinutrient formulas. The new Super Booster also provides sesame lignans to enhance the dissemination of gamma-tocopherol to cells throughout the body.
In human and animal studies, administration of sesame lignans increases tissue and serum levels of gamma and alpha-tocopherol. This is critical because gamma-tocopherol, but not alpha-tocopherol, quenches reactive nitrogen species, such as the dangerous peroxynitrite radical. Studies have shown that adding sesame to a rat diet reduced a measurement of free-radical damage by 82.8%. A human study conducted by Life Extension showed that the combination of gamma-tocopherol and sesame was 25 percent more effective in suppressing blood markers of free-radical damage and inflammation compared to gamma-tocopherol and tocotrienols.
To reduce the cost and inconvenience of taking many different pills, Life Extension Super Booster provides optimal doses of ginkgo extract, vitamin K, chlorophyllin, lycopene, gamma-tocopherol, sesame, and other nutrients in just one capsule.
