3977 participants in the Age-Related Eye Disease Study were followed for 8 years by Chung-Jung Chiu and a team at Tufts University, who tracked the glycemic index of their diets and the development of age-related macular degeneration (AMD). The scientists concluded that seniors at risk of AMD may “benefit from consuming a smaller amount of refined carbohydrates.”

Forty-one breast-feeding Japanese mothers were randomly divided into two groups, one eating white rice and the other sprouted brown rice, for two weeks. When psychological and immune tests were administered to both groups, the sprouted brown rice group was found to have decreased scores of depression, anger-hostility, and fatigue, and a significant increase in s-igA levels, indicating better immune system function.

Fatty liver disease, like alcohol-induced cyrrhosis, can lead to terminal liver failure, and it’s increasing, as it often goes hand in hand with type 2 diabetes. Korean researchers found that buckwheat sprouted for 48 hours developed “potent anti-fatty liver activities” that significantly reduced fatty liver in mice after 8 weeks. Scientists found that sprouting the buckwheat increased the concentration of rutin tenfold, and also increased quercitin, both of which are known for their anti-inflammatory effects.

Researchers at Harvard studied nearly 30,000 enrolled in the Women’s Health Study. Lu Wang’s team found that, over ten years, those who ate the most whole grains had an 11% lower chance of developing high blood pressure.

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.

German researchers sprouted wheat kernels for up to 168 hours (1 week), analyzing them at different stages to learn the effects of germination on different nutrient levels. While different times and temperatures produced different effects, overall the sprouting process decreased gluten proteins substantially, while increasing folate. Longer germination times led to a substantial increase of total dietary fiber, with soluble fiber tripling and insoluble fiber decreasing by 50%.

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.

That habitual whole grain consumption reduces the risk of both cardiovascular disease and diabetes has been well documented. Now, a recent study by the University of Minnesota’s David Jacobs shows that eating whole grains confers an even greater risk-reduction in mortality from inflammatory diseases. Jacobs and his colleagues followed more than 27,000 post-menopausal women for 17 years and concluded that “oxidative stress reduction by constituents of whole grain is a likely mechanism for the protective effect.”

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.

People’s eating patterns are greatly influenced by where they live. This study examined the eating patterns of 181 adult Haitians living in Montreal to measure the quality of their diets, as they transitioned from traditional Haitian lifestyles to a more North American way of life. Diet quality was broken down into a categorical spectrum, spanning from “Traditional” to “Western.” The researchers found that people who ate a “Traditional” diet, which was lowest in cholesterol and total fat, tended to be older and to have lived in Montreal for the shortest periods of time. The longer a person had lived in Montreal, the more “Western” their diet became, exceeding the recommended limits of total fat and cholesterol intake. Overall diet quality was significantly healthier in the “Traditional” diets than the “Western” type. The study concluded that it is important to encourage youth to retain their healthy traditional food cultures no matter where they live.

A team of researchers led by Arthur Schatzkin studied data for almost half a million middle-aged men and women enrolled in the NIH-AARP Diet and Healthy Study, to learn whether fiber intake and/or whole grains might reduce the risk of colorectal cancer. In this analysis, total dietary fiber intake was not associated with a reduced risk of colorectal cancer, but both grain fiber and whole grains were shown likely to reduce the risk of colorectal cancer.

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.
