Fiber Improves Metabolic & Cardiovascular Markers

Posted Apr 30 2013 10:07pm

While a diet rich in fiber seems to protect against the Metabolic Syndrome, there is scarce information about the role of fiber intake in patients who have these conditions.  Valesca Dall'Alba, from Universidade Federal do Rio Grande do Sul (Brazil), and colleagues enrolled 44 type-2 diabetics, average age 62 years, and randomly assigned each subject to one of two groups: an intervention group – who consumed a usual diet supplemented with an additional 10 grams per day of guar gum; or a control group who consumed a usual diet only.  After  six weeks, the fiber-supplemented group decreased glycated hemoglobin (HbA4c) by 0.31% and lowered trans fatty acid levels from 71 to 57 mg/L; their waist circumference dropped from 103.5 cm to 102.3 cm. The only change in the control group was a 0.9 cm reduction in waist circumference.  The study authors conclude that: “the addition of [soluble fiber] to the usual diet improved cardiovascular and metabolic profiles by reducing [waist circumference], [glycated hemoglobin], [urinary albumin excretion], and [serum trans-fatty acids].”

Tip #155 - “D” feat Depression
Whereas the therapeutic role of vitamin D, “the sunshine vitamin,” for bone health, has become well established, some studies suggest that vitamin D deficiencies may contribute to cancer, cardiovascular disease, high blood pressure, type 2 diabetes, and some infectious diseases. Researchers from Vrije Universiteit Medical Center (The Netherlands) report a link between insufficient Vitamin D and increased risk of depression. Studying 1,282 men and women, ages 65 to 95 years, the team found that subjects with major and minor depression had blood vitamin D levels 14% lower than participants who were not depressive.
