A recent study investigated the relationship between vitamin D levels and breast cancer incidence. The study used data from 107 countries and found that those with higher levels of vitamin D and living closer to the equator (more sunlight) had less incidences of breast cancer. These results were independent of alcohol intake, meat intake, being overweight and other variables.* This study is not necessarily promoting more sun exposure, but suggests [...]

According to the American Journal of Clinical Nutrition, Increasing evidence supports omega-3 fatty acid supplementation for patients with psychiatric disorders, such as attention deficit hyperactivity disorder (ADHA). Children, ages 8-13, who participated in the study consumed eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), agents found in omega-3 fatty acid. The study’s measurements included continuous performance test results, including the test of variable attention (TOVA). TOVA is a computerized test of [...]

Last month Archives of Ophthalmology published a meta analysis on omega-3 fatty acid and fish intake and its effect on the prevention of age-related macular degeneration (AMD). This study identified 274 abstracts, 3 prospective cohort, 3 case-control, and 3 cross-sectional studies. Using quantitative methods, a high dietary intake of omega-3 fatty acids was associated with a 38% reduction in the risk of late AMD. Fish intake (2x per week) was [...]

A French study of 1,390 elderly participants studied the blood levels of omega-3 fatty acids (EPA) and the relationship to depression. Depression was evaluated using the Center for Epidemiological Studies Depression scale.* The study found that the EPA levels and depressive symptoms were inversely related. Higher EPA in the blood (omega-3) was associated with a “lower severity of depressive symptoms in elderly subjects, especially those taking antidepressants.” Viteyes offers an [...]

Archives of General Psychiatry published a recent study on vitamin D and depression. Low levels of Vitamin D and higher levels of parathyroid hormone (PTH) were found to be associated with depression among 1,282 community residents aged 65 to 95 years. Researches studied this group to determine whether there is an association between depression, vitamin D levels and the parathyroid hormone (PTH). Depression was measured using self-reports, and diagnostic interviews.* [...]

A recent study published in the May 2008 issue of American Journal of Clinical Nutrition, studied the effects of lutein and docosahexaenic acid (DHA – omega-3) on macular degeneration. This four-month study researched 59 women, 60 to 80 years old. The women were randomly assigned a placebo, DHA, lutein, or lutein plus DHA supplement.* Lutein is found in the healthy macula. DHA is found in the retina. Researchers wanted to [...]

Omega-3 fatty acid dietary supplements may help with symptoms associated with depression, suggests a joint Anglo-Iranian study. This study researched the therapeutic effects of EPA (eicosapentaenoic acid) found in omega-3 fatty acid and people with major depression. The study compared omega-3 to fluoxetine, and a combination of the two. Sixty participants were given either 1000 mg EPA, 20 mg fluoxetine, or a combination for 8 weeks. Patients in this double [...]

Type 1 diabetes is an autoimmune disease that can destroy the beta cells of the pancreas, which make and release the hormone, insulin. Scientists from the University of California, Davis, hypothesized that feeding diabetic, non-obese mice diets rich in polyphenols, or vitamin A, would lessen the autoimmune inflammatory process associated with type 1 diabetes.  These researchers studied 45 female, non-obese mice, and found the incidence of diabetes was reduced to 25% from 33% in mice receiving 1% dietary [...]

The amount of carotenoids, lutein and zeaxanthin, in the macula are thought to affect the development of age-related maculopathy (ARM). A recent Japanese study researched the levels of carotenoids in normal Japanese participants versus those with ARM.* The study found that normal levels of lutein and zeaxanthin in the macula were about 1471 “units”. Those with early AMD had a mean of only 620 units and those with late AMD had a mean of only 427 units [...]
