A novel carbon isotope biomarker for dietary sugar.
نویسنده
چکیده
Light element isotope signatures have been used to study food webs in many ecological niches, including those of ancient humans, but to a far lesser extent in modern humans. A recent paper presented results from a pilot study testing the utility of carbon isotope ratio analysis of alanine to measure an individual's sugar intake in the United States. A strong correlation was found between the enrichment of (13)C in alanine and sugar-sweetened beverage consumption. This candidate biomarker of sugar consumption deserves further consideration as an objective marker for use in the study of the relationship between sugar intake and health.

The carbon isotope ratio of alanine in red blood cells is a new candidate biomarker of sugar-sweetened beverage intake.
An objective dietary biomarker would help clarify the contribution of sugar-sweetened beverage (SSB) intake to obesity and chronic disease risk. Previous studies have proposed the carbon isotope ratio (δ(13)C) as a biomarker of SSB intake but found associations that were of modest size and confounded by other components of the diet. We investigated whether the δ(13)C values of nonessential amin...
متن کاملAssociation of δ¹³C in fingerstick blood with added-sugar and sugar-sweetened beverage intake.
A reliance on self-reported dietary intake measures is a common research limitation, thus the need for dietary biomarkers. Added-sugar intake may play a role in the development and progression of obesity and related comorbidities; common sweeteners include corn and sugar cane derivatives. These plants contain a high amount of ¹³C, a naturally occurring stable carbon isotope. Consumption of thes...
متن کاملAn isotopic method for quantifying sweeteners derived from corn and sugar cane.
BACKGROUND Consumption of high-fructose corn syrup, as well as cane sugar, has been implicated in the rise of the obesity and diabetes epidemics. To date, however, no reliable biomarker for the consumption of these sweeteners is available. OBJECTIVE The objective of the study was to determine the natural abundance stable-carbon-isotope signature of commonly consumed foods of plant origin. D...
متن کاملResource allocation to reproduction and soma in Drosophila: a stable isotope analysis of carbon from dietary sugar.
Metabolic resources in adults of holometabolous insects may derive either from larval or adult feeding. In Drosophila melanogaster, reproduction and lifespan are differently affected by larval vs. adult resource availability, and it is unknown how larval vs. adult acquired nutrients are differentially allocated to somatic and reproductive function. Here we describe the allocation of carbon deri...
متن کاملHummingbirds fuel hovering flight with newly ingested sugar.
We sought to characterize the ability of hummingbirds to fuel their energetically expensive hovering flight using dietary sugar by a combination of respirometry and stable carbon isotope techniques. Broadtailed hummingbirds (Selasphorus platycercus) were maintained on a diet containing beet sugar with an isotopic composition characteristic of C3 plants. Hummingbirds were fasted and then offered...
