Summary
Consuming yogurt with D-lactic acid does not pose a health risk for healthy adults. Studies show it does not lead to D-lactic acidosis or metabolic acidosis.
Area of Science:
- Biochemistry
- Human Physiology
- Food Science
Background:
- D-lactic acid is a metabolite produced by gut bacteria.
- Concerns exist regarding potential health risks of D-lactic acid accumulation.
- Yogurt is a common food source containing lactic acid isomers.
Purpose of the Study:
- To investigate the physiological effects of consuming D-lactic acid in yogurt.
- To assess the risk of D-lactic acidosis in healthy adults after yogurt consumption.
- To compare the metabolic response to D-lactic acid from yogurt versus an aqueous solution.
Main Methods:
- Seven healthy volunteers participated in the study.
- Postprandial plasma D-lactate concentrations were measured after yogurt ingestion.
- D-lactate levels were compared to those after consuming an aqueous DL-lactate solution.
Main Results:
- Yogurt consumption led to increased plasma D-lactate levels.
- The peak D-lactate concentration after yogurt was lower and broader than with an aqueous solution.
- No signs of metabolic acidosis were observed after consuming yogurt with D-lactic acid.
Conclusions:
- Consumption of foods containing D-lactic acid, such as yogurt, is safe for healthy adults.
- The body effectively metabolizes D-lactic acid from yogurt without adverse effects.
- There is no evidence to support concerns about D-lactic acidosis from dietary D-lactic acid sources.
