Oats May Help Reduce the Risk of Type 2 Diabetes

Researchers in Mannheim, Germany carried out a dietary intervention with 14 patients who had uncontrolled type 2 diabetes and insulin resistance. The patients were introduced to a diabetes-appropriate diet containing oatmeal during a short hospital stay, then examined again four weeks later. On average, patients achieved a 40% reduction in insulin dosage – and maintained the reduction even after 4 weeks on their own at home.

Chronic Disease risks reduced with whole grain

A team of scientists in Boston and Baltimore led by PK Newby studied data from the Baltimore Longitudinal Study of Aging, and found that seniors consuming the most whole grain had lower body mass index (BMI) and weight, and smaller waist circumference. More whole grain consumption was also associated wtih lower total cholesterol, lower LDL cholesterol and improved glucose response.

Two Whole Grain Servings Reduce Diabetes Risk

At the Harvard School of Public Health, researchers led by JS de Munter pooled data from six cohort studies including 286,125 participants, and found that a two-servings a day increment in whole grain consumption was associated with a 21% decrease in risk of type 2 diabetes.

Oats May Improve Insulin Sensitivity

Researchers in Chicago carried out a randomized, double-blind, controlled clinical trial of ninety-seven men and women, in which half of the group consumed foods containing oat beta-glucan, while the other half ate control foods. At the end of the trial period, the oat group showed improvements in insulin sensitivity, while the control group was unchanged.

More Cereal Fiber associated with less diabetes risk

A team of German researchers led by Matthias Schulze followed over 16,000 adults for a period of seven years and found that those who ate the most cereal fiber had a 27% lower risk of developing diabetes than those who ate the least. No link was noted with total fiber – just with cereal fiber.

High Fiber Diet cuts Inflammation Levels

C-reactive protein (CRP), a known marker for inflammation, is increasingly accepted as a good predictor of both type 2 diabetes and cardiovascular disease. A high-fiber diet – whether from foods like whole grains, fruits and vegetables or from fiber supplements – can cut CRP levels up to 40%. Ironically, the effect was more pronounced in healthy lean people than in obese ones, according to lead researcher Dana King at the Medical University of South Carolina.

Brown Rice, for lower blood glucose in Healthy and Diabetic Subjects

Lower post-prandial blood glucose response can be important both for preventing and for controlling diabetes. In a study at the University of the Philippines, researchers used a randomized cross-over design to compare the effects on blood glucose of brown rice and white rice on 10 healthy and nine Type 2 diabetic volunteers. In healthy volunteers, the glycemic area and glycemic index were, respectively, 19.8% and 12.1% lower with brown rice than with white rice; with diabetics, the same values for brown rice were 35.2% and 35.6% lower than with white rice.

Children Benefit Quickly from Healthy Diet

Overweight children, age 9-15, spent two weeks on an all-you-can-eat diet of whole grains, fruits, vegetables and lean protein, while exercising 2.5 hours each day. UCLA researchers led by Dr. James Barnard reported that in just two weeks the children’s cholesterol levels dropped an average of 21%, while insulin levels fell 30%. Leptin, a hormone thought to be connected to appetite, decreased on average 57%.

Whole Grains Lower Diabetes, Heart Risk

A joint Danish-American study analyzed diet records and took blood samples from 938 healthy men and women. The team, including Majken Jensen of Aarhus University Hospital and the Harvard School of Public Health, found that those with the highest whole grain consumption had the lowest levels of risk factors in their blood: homocysteine 17% lower, insulin and C-peptide both 14% lower, and leptin 11% lower. Researchers concluded, “The results suggest a lower risk of diabetes and heart disease in persons who consume diets high in whole grains.”

Whole Grains Reduce Elderly Mortality

While many studies have previously shown that whole grains reduce the risk of metabolic syndrome in middle-aged adults, a recent study led by Nadine Sahyoun at the University of Maryland shows for the first time that this benefit extends to older adults. In Sahyoun’s study, whole grains were also linked with a lower overall risk of mortality from cardiovascular disease.

Barley Beats Oats in Glucose Response Study

USDA researchers fed barley flakes, barley flour, rolled oats, oat flour, and glucose to 10 overweight middle-aged women, then studied their bodies’ responses. They found that peak glucose and insulin levels after barley were significantly lower than those after glucose or oats. Particle size did not appear to be a factor, as both flour and flakes had similar effects.

Magnesium May Explain Diabetes Benefits of Whole Wheat

It’s thought that foods with a lower glycemic index may improve insulin sensitivity. Yet whole wheat bread, with a glycemic index almost identical to bread made with refined wheat, has been found to promote insulin sensitivity when compared to the “white bread.” Researchers at Pantox Laboratories in San Diego, California, hypothesize that magnesium may be responsible, and urged “the strong desirability of choosing whole grain products in preference to refined grains.”
