Traditional Japanese Breakfast Foods Improve Glucose Tolerance

Researchers studied the effect of traditional Japanese breakfast foods on insulin sensitivity in a small sample of individuals with impaired glucose tolerance.  The group which ate foods such as natto (fermented soybeans) and viscous vegetables (such as Japanese yams and okra) for 2 weeks demonstrated improved insulin sensitivity, serum lipids, and oxidative stress compared to the control group.

Green Tea May Aid Weight Control

Chinese researchers seeking to evaluate the effect of green tea in combination with inulin for potential impact on body weight and fat mass asked 30 obese and overweight adults to drink either regular tea or catechin-rich green tea with inulin, for six weeks.  Researchers concluded that continuous intake of green tea and inulin may support weight management, and that the positive effects continued were sustained two weeks after ending consumption.

Hawthorn and Kiwifruit Extracts May Improve Lipid Status

Traditional Chinese therapeutic foods such as hawthorn and kiwifruit extracts were evaluated for their effect on dyslipidemia in a clinical trial conducted in Australia.  Researchers found evidence which suggests that consuming these extracts for 4 weeks may increase levels of HDL-c “good cholesterol” which could reduce the risk of cardiovascular disease.

Nutrition Transition Alters Cancer Risks

Researchers in China systematically evaluated rates of cancer mortality in China, Hong Kong, Japan, Korea and Singapore, and noted changes that began to occur about 10 years into a “nutrition transition” characterized by increased intake of energy, animal fat, and red meats. Breast, colon, and prostate cancer mortality increased “remarkably,” while esophageal and stomach cancers showed a “precipitous decrease.”

Asian Herbal Food Ingredients May Impact T2DM

Many herbal food ingredients of Asian origin -- such as garlic, onion, fenugreek, and pomegranate -- may have medicinal properties.  Scientists in Nanjing, China reviewed the literature, and suggest that some of these ingredients may be beneficial in the treatment of Type 2 diabetes based on their chemical components.  These foods merit further research based on the increasing prevalence of diabetes.

Diet and Metabolic Syndrome in Korean Women

Researchers evaluated the dietary patterns of Korean women in relation to the prevalence of metabolic syndrome.  Three overall patterns were identified: Western, Healthy, and Traditional.  The Healthy pattern features a higher intake of green-yellow vegetables and lean proteins and was associated with a reduced risk of metabolic syndrome in post-menopausal women compared to the Western and Traditional patterns.

Gender Differences in Acculturation for Korean Immigrants

Based on a survey of Korean immigrants living in the United States, researchers at Queens College in New York City concluded that acculturated Korean immigrants consumed both healthy and unhealthy American foods.  Overweight men were reported to eat more fast food, hot dogs, and tacos than men of healthy weight.  Researchers noted gender differences in acculturation that should be considered for future research and health initiatives.

Southern Chinese Diet & Risk of Stroke

The traditional southern Chinese diet consists of a higher intake of rice and vegetables and moderate intake of seafood, pork, and poultry, while the northern Chinese diet consists of a higher intake of refined wheat cereal products and potatoes.  The dietary pattern in southern China was associated with the lowest prevalence of stroke compared to the northern Chinese and Western diets.
