Western Diet Linked with Greater Mortality

After following 72,113 women for almost twenty years, researchers at the Harvard School of Public Health concluded that eating a “prudent” diet rich in vegetables, fruits, legumes, whole grains, fish and poultry may reduce the risk for cardiovascular disease and for overall mortality. The study divided the women into two groups, those eating the “prudent” diet and those consuming a typical “Western” diet with high levels of red meat, processed meat, refined grains, french fries, and sweet or desserts.

Study Confirms Heart Benefits of Whole Grains

Eating an average of 2.5 servings of whole grain foods each day can lower your risk of cardiovascular disease by almost one-quarter. That’s the finding of a seven-study meta-analysis of 285,000 men and women led by Philip Mellen of Wake Forest University. In light of this evidence, Mellen said, policy-makers, scientists and clinicians should “redouble efforts” to get people to eat more whole grains.

Amaranth May Have Cancer-preventing, Anti-inflamatory Properties

Molecular biologists in Mexico set out to study the bioactive peptides in amaranth and, in 2008, were the first to report presence of a lunasin-like peptide in the protein in amaranth.  Lunasin is a peptide previously identified in soybeans and is widely thought to have cancer-preventive benefits as well as possibly blocking inflammation that accompanies several chronic health conditions such as diabetes, heart disease, and stroke.  Additional bioactive peptides in amaranth protein were found to have antihypertensive properties.

Whole Grains Reduce Weight, Cut CVD Risk

In a clinical study conducted at Penn State, researchers put 50 obese adults on a reduced calorie diet for 12 weeks, during which time half the group was asked to eat all their grains as whole grains, and the other half was advised to avoid whole-grain foods. Body weight, waist circumference and percentage body fat decreased significantly in both groups, but the whole grain group saw a signicantly greater decrease in abdominal fat, and a 38% decrease in C-reactive protein (CRP), an inflammatory marker for cardiovascular disease.

Cardiovascular Risk Reduced by Sprouted Rice

In a Korean study, rats on a high-cholesterol diet were divided into four groups, a control group and three experimental groups which were fed (1) sprouted giant embryonic rice, (2) giant embryonic rice, or (3) conventional brown rice.  (Giant embryonic rice is rice with a larger germ than normal.)  Rats fed the sprouted rice saw a rise in their plasma HDL-cholesterol (“good cholesterol”) and other markers that led researchers to conclude that “consumption of germinated giant embryonic rice is effective in lowering atherosclerosis cardiovascular disease risk.”

Whole Grain Cereal for Healthier Hearts

After following 21,376 male physicians for almost 20 years, Luc Djoussé and J. Michael Gaziano at Harvard found that those eating two to six servings of whole grain cereal a week reduced their risk of heart failure 22%, while those eating whole grains daily reduced risk by 28%. For this study, cereals with at least 25% whole grain or bran by weight were classified as whole grain.

Whole Grain and Healthier Carotid Arteries

A study by Philip Mellen at Wake Forest University and colleagues measured atherosclerosis of the common carotid artery, and its progression over five years. Mellen’s team found that, among the 1178 men and women in the study, those who ate more whole grains had less unhealthy artherosclerotic thickening of the common carotid artery.

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.

Amaranth Benefits Patients With Cardiovascular Disease

Russian researchers seeking to determine whether or not amaranth would show benefits for  cardiovascular disease (CVD) fed daily doses of amaranth oil or sunflower oil (a control) to 125 patients with CVD.  Patients who presented with coronary heart disease and hypertension not only showed benefits from the inclusion of amaranth in their diets, researchers also saw a decrease in the amounts of total cholesterol, triglycerides, and LDL significantly.

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.

Whole Grains Slow Buildup of Plaque

Following up on studies that show a relationship between whole grain consumption and heart health, researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, led by Alice Lichtenstein, have found one reason why. Over 3 years, they studied the diet habits and artery-diameter measurements of 229 post-menopausal women already diagnosed with a heart condition, and found that eating 6 servings or more per week of whole grains was associated with slower buildup of artery-narrowing plaque.
