“…Red rice was found to have a lower glycemic index compared with white rice (Anitha et al, 2017). In addition, intake of white and brown rice was both associated with higher total urinary arsenic concentrations, and the inorganic arsenic concentrations were not different between participants who primarily ate white rice versus those who ate brown rice (Wu et al, 2015 Black rice possessed a thicker bran layer than red rice. Non-milled red rice showed higher antioxidant activity than non-milled black rice (Paiva et al, 2014;Shao et al, 2017) Phytic acid was found to be negatively correlated to the antioxidant activity (Kaur et al, 2017).…”

Rice is a staple food for Indonesians. Therefore, awareness of the nutritive value and the health benefit of rice is of vital importance. This study was conducted with the objective to evaluate the nutritional value, functional properties of rice, blood glucose response and glycemic index of the North and East Borneo native rice, such as the Red Mayas (RM), white Mayas (WM), red Adan (RA), white Adan (WA), and black Adan (BA). Proximate levels (proteins, fats, carbohydrates, ash, and water) in BA, WA, RM, WM, and RA are generally different from the highest levels of protein, fat, calories in BA rice. The highest insoluble dietary fiber in BA was 0.91g/100 g and the lowest is RA. The iron content in WA is 3-5 times higher than other local rice 14.48 mmg/100 g. The highest content of vitamin B1 (thiamine) indicated by RA is 0.38 mg/100 g, while the lowest is WA, which is 0.17 mg/100 g. Thus, the highest amylopectin and amylose content is RA, which is 69.09 g/100 g. Longer glucose is stored in the blood, namely BA and the five types of local rice in East and North Borneo, which show a high glycemic index.

“… 9 , 11 , 14 – 21 In the National Health and Nutrition Examination Survey (NHANES), a representative sample of the US population, rice consumption was associated with increased urinary arsenic concentrations in children 22 and adults. 23 , 24 The presence of arsenic in food is generally due to naturally occurring soil contamination, past use of pesticides or contaminated irrigation water. 25 , 26 In poultry, however, the presence of arsenic can be due to the use of arsenical drugs as feed additives, such as roxarsone which was used in chicken production in the US until its ban in 2013 27 and nitarsone, which was used in turkey production at least through the end of 2015.…”

Differences in residential location as well as race/ethnicity and dietary habits may result in differences in inorganic arsenic (iAs) exposure. We investigated the association of exposure to iAs with race/ethnicity, geography and dietary intake in a random sample of 310 White, Black, Hispanic and Chinese adults in the Multi-Ethnic Study of Atherosclerosis from 6 US cities with inorganic and methylated arsenic (ΣAs) measured in urine. Dietary intake was assessed by food frequency questionnaire. Chinese and Hispanic race/ethnicity was associated with 82% (95% CI: 46%, 126%) and 37% (95% CI: 10%, 70%) higher urine arsenic concentrations, respectively, compared to White participants. No differences were observed for Black participants compared to Whites. Urine arsenic concentrations were higher for participants in Los Angeles, Chicago and New York compared to other sites. Participants that ate rice ≥2 times/week had 31% higher urine arsenic compared to those that rarely/never consumed rice. Participants that drank wine ≥2 times/week had 23% higher urine arsenic compared to rare/never wine drinkers. Intake of poultry or non-rice grains was not associated with urinary arsenic concentrations. At the low-moderate levels typical of the US population, exposure to iAs differed by race/ethnicity, geographic location and frequency of rice and wine intake.

“…Consumption or rice and rice products is another important potential contributor to urinary As concentrations (Karagas et al 2016;Wu et al 2015). Hence, both seafood consumption and rice consumption during the previous 24 h were included as covariates in our models.…”

Exposure to inorganic arsenic (inAs), a potent toxicant, occurs primarily through ingestion of food and water. The efficiency with which it is methylated to mono and dimethyl arsenicals (MMA and DMA) affects toxicity. Folate, vitamins B12 and B6 are required for 1C metabolism, and studies have found that higher levels of these nutrients increase methylation capacity and are associated with protection against adverse health effects from inAs, especially in undernourished populations. Our aim was to determine whether 1C-related nutrients are associated with greater inAs methylation capacity in a general population sample with overall adequate nutrition and low levels of As exposure. Univariate and multivariable regression models were used to evaluate the relationship of dietary and blood nutrients to urinary As methylation in the National Health and Nutrition Examination Survey (NHANES) 2003-2004. Outcome variables were the percent of the sum of inAs and methylated As species (inAs+MMA+DMA) excreted as inAs, MMA, and DMA, and the ratio of MMA:DMA. In univariate models, dietary folate, vitamin B6 and protein intake were associated with lower urinary inAs% and greater DMA% in adults (≥18years), with similar trends in children (6-18). In adjusted models, vitamin B6 intake (p=0.011) and RBC folate (p=0.036) were associated with lower inAs%, while dietary vitamin B12 was associated with higher inAs% (p=0.002) and lower DMA% (p=0.030). Total plasma homocysteine was associated with higher MMA% (p=0.004) and lower DMA% (p=0.003), but not with inAs%; other blood nutrients showed no association with urinary As. Although effect size is small, these findings suggest that 1C nutrients can influence inAs methylation and potentially play an indirect role in reducing toxicity in a general population sample.
