Barley varieties such as Prowashonupana that are especially high in beta-glucan fiber may digest more slowly than standard barley varieties. Researchers at USDA and the Texas Children’s Hospital compared the two and concluded that Prowashonupana may indeed be especially appropriate for obese and diabetic patients.

Researchers at Colorado State University randomly assigned thirty-six overweight middle-aged men to eat either an oat or wheat cereal daily for twelve weeks. At the end of the three-month period, the men eating the oat cereal had lower concentrations of small, dense LDL cholesterol (thought to be particularly dangerous) and lower LDL overall, compared to those in the wheat group, while their HDL (“good”) cholesterol was unchanged.

Researchers from the London School of Hygiene and Tropical Medicine compared the diets of 240 South Asian women who had breast cancer with age-matched South Asian women who did not. They found that there was a slight reduction in the risk of breast cancer among women who identified as lifelong vegetarians compared with those who identified as lifelong meat-eaters. The researchers believe that reduction in the risk of breast cancer among lifelong vegetarians is most likely related to increased consumption of vegetables and pulses (legumes).

Using a randomized, controlled parallel-group pilot study, researchers followed 18 hypertensive and hyperinsulemic men and women for six weeks, while half of them ate oat cereal (5.52g/day of beta-glucan) and the others ate a lower-fiber cereal (less than 1g total fiber). The oat group enjoyed a 7.5mm Hg reduction in systolic blood pressure and a 5.5 mm Hg reduction in diastolic blood pressure, while the wheat group was unchanged.

The dietary intake in Thailand has changed dramatically over the last 30 years, with a trend toward increased consumption of animal fat, animal meat and convenience foods, and decreased consumption of Thai staples and side dishes.  The prevalence of childhood and adolescent obesity in Thailand is increasing, and adults are facing increased incidence of chronic disease. Today, diet-related chronic degenerative diseases are the leading cause of death in Thailand.

This study at Emory University reported on Eat for Life, a health intervention initiative to increase fruit and vegetable consumption among African Americans. Fourteen black churches were randomly assigned to give various levels of intervention and support to participants. One group received a one-time motivational health counseling call, while another group received a series of health counseling calls, enjoying ongoing motivational support. In a follow-up after 1 year, fruit and vegetable intake was assessed by three food frequency questionnaires. Change in fruit and vegetable intake was significantly greater in the group that received several counseling calls than in the group that received only one. Ongoing counseling support appears to be an effective strategy for helping people change the way they eat, and Black churches are an excellent setting to provide and evaluate health promotion programs.

Africans carried their foods and dietary customs into diaspora throughout the Americas as a result of the European slave trade. Their descendants represent populations at different stages of a nutrition transition. West Africans are more often in the early stage, where there are many challenges and conditions like undernutrition and nutrient deficiencies. Many Caribbean populations represent the middle stages, with undernutrition and obesity co-existing. African Americans and black populations in the United Kingdom suffer the worst, from the consequences of caloric excess and diets high in fat and animal products. Obesity, diabetes, high blood pressure, coronary heart disease, and certain cancers are prevalent in the African-American and Afro-British populations, and they are beginning to emerge in populations that never before faced these diseases, as diets become more Western.

Scientists at the University of Alberta germinated wheat under various conditions to determine how to maximize the production of antioxidants.  First, they steeped the grains in water for 24 or 48 hours, then sprouted them in the dark for 9 days. Vitamins C and E and beta-carotene, which were barely detectable in the dry grains, increased steadiily during the germination period. Grains steeped for 48 hours became wet, sticky, discolored and acidic-smelling after germination, leading researchers to conclude that 24 hours of steeping and 7 days of sprouting would produce the best combination of antioxidant concentrations and sensory properties.

Reviewing data from around the world, Barry Popkin assessed associations between activity, food intake, and health over time and found “a marked shift in the structure of the diet.” Not only are dietary changes tied to increases in obesity, but they are occurring so rapidly that both malnutrition and obesity are co-existing in the same households.

Tanzanian researchers observed that sorghum, although a staple food in many poorer areas of the world, is not highly esteemed, because of limits in its nutritional and sensory qualities. In an effort to make this easy-to-grow grain more useful and more widely accepted, they studied three traditional processing methods: germination (sprouting), fermentation, and a germination/fermentation comination.  They concluded that germination was the best approach for improving the nutritional and functional qualities of the sorghum.

Scientists in Madrid studied the effect of three different components from wine and one from sorghum, to gauge their effects on the growth of human melanoma cells. While results were mixed, they concluded that all four components (phenolic fractions) “have potential as therapeutic agents in the treatments of human melanoma” although the way in which each slowed cancer growth may differ.

In a joint effort to determine the characteristics of buckwheat starch and its potential for a reduced metabolic response after meals, researchers from Slovenia and Sweden scored human test subject’s responses to an assortment of buckwheat products, including boiled buckwheat groats, breads baked with 30-70% buckwheat flour, and bread baked from buckwheat groats. The highest level of resistant starch was found in the boiled buckwheat groats, while the resistant starch levels in the buckwheat breads were significantly lower, depending on whether flour or grouts had been used. The conclusion? All buckwheat products scored significantly lower on the after-meal blood glucose tests, while also scoring higher in satiety, than the control group’s white wheat bread.
