University of Iowa study examines link between obesity, food container chemical subsitutes. The new University of Iowa College of Public Health study is the first to determine the health impacts of BPF and BPS exposure on obesity in humans.
The research was supported by the National Institutes of Health through the University of Iowa Environmental Health Sciences Research Center
But the study found no links between obesity and either BPF or BPS at the current exposure levels.
Whether BPF and BPS pose an increased risk of obesity at the same population exposure levels as BPA remains unknown.
The chemical is absorbed into the body mainly through the food or water it contacts in the container.
It is not well understood why drinking artificially sweetened beverages compared to drinking water may increase obesity risk.
They also call for additional investigation on the effects of drinking artificially sweetened beverages among high-risk racial/ethnic groups.
Consuming a daily artificially sweetened beverage appeared to offer no advantages over consuming a daily sugar-sweetened beverage.
The authors mention specifically the need for studies that use more contemporary data, given recent upward trends in the consumption of artificially sweetened beverages.
Citing prior research implicating artificially sweetened beverages in weight gain, the study authors sought to determine if diet beverage consumption during pregnancy could influence the weight of children.
Drinking diet beverages during pregnancy linked to child obesity, NIH study suggests
according to The team gathered accurate whole-body and abdominal fat data using a total body dual energy X-ray absorptiometry (DXA) scanner — a highly accurate way of measuring body composition and fat content.
The five predictors tested were: BMI, waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and waist-to-height ratio0.5 (WHtR0.5).
This is most definitely the case when people have a ‘normal’ BMI but high abdominal fat that is often dismissed.
In current clinical practice, it is common to calculate BMI for an indication of whole-body fat and waist circumference for abdominal obesity.
Calculating a person’s waist-to-height ratio is the most accurate and efficient way of identifying whether or not they are at risk of obesity in clinical practice, a new study by Leeds Beckett University shows.
