BACKGROUND Obesity has become one of the most important and the fastest growing health and nutritional problem, not only in developed but also in developing countries. White rice consumption causes an increase in postprandial blood glucose and could be a probable reason for obesity. This study was conducted to investigate the association between intake of white rice and central obesity in an Ir...

BACKGROUND Because of differences in processing and nutrients, brown rice and white rice may have different effects on risk of type 2 diabetes mellitus. We examined white and brown rice consumption in relation to type 2 diabetes risk prospectively in the Health Professionals Follow-up Study and the Nurses' Health Study I and II. METHODS We prospectively ascertained and updated diet, lifestyle...

In China, total Hg (HgT) and methylmercury (MeHg) were quantified in rice grain grown in three sites using water-saving rice cultivation methods, and in one Hg-contaminated site, where rice was grown under flooded conditions. Polished white rice concentrations of HgT (water-saving: 3.3±1.6 ng/g; flooded: 110±9.2 ng/g) and MeHg (water-saving 1.3±0.56 ng/g; flooded: 12±2.4 ng/g) were positively c...

BACKGROUND Whole-grain products such as brown rice have been associated with lower risk of metabolic disorders including diabetes. We examined the acceptability and tolerability of substituting brown rice for white rice and the feasibility of introducing brown rice into the diet through a long-term trial to lower the risk of type 2 diabetes. METHODS Fifty-one adults residing in Abuja, Nigeria...

The present study compared the effects of three rice cultivars on postprandial glycemic control and appetite. A single-blind, randomized, crossover clinical trial was performed with 18 healthy subjects, nine males and nine females. Three treatments were administered at three separate study visits: commercially available conventional white rice (short grain), specialty high amylose white rice 1 ...

Association between white rice intake and risk factors of cardiovascular diseases remained uncertain. Most of the previous published studies have been done in western countries with different lifestyles, and scant data are available from the Middle East region, including Iran. This cross-sectional study was conducted in the structure of Isfahan Healthy Heart Program (IHHP) to assess the associa...

The comparative effects of instant cooked rice made from giant embryo mutant or ordinary normal rice on body weight and lipid profile in high fat-fed mice were investigated. The animals were given experimental diets for seven weeks: normal control (NC), high fat (HF), and HF supplemented with instant normal white (HF-NW), normal brown (HF-NB), giant embryonic white (HF-GW), or giant embryonic b...

BACKGROUND Evidence on biological activities of cooked black rice is limited. This study examined the effects of washing and cooking on the bioactive ingredients and biological activities of black rice. METHODS Cooked rice was prepared by washing 0-3 times followed by cooking in a rice cooker. The acidic methanol extracts of raw and cooked rice were used for the analyses. RESULTS Raw black ...
