Physical Factors of Food Influencing the Postprandial Blood or Plasma Glucose Level: A Narrative Review

Main Article Content

Robbert Bipat Indira Magali Rubaina Soekhoe Jerry Toelsie


Emerging evidence suggests that a high postprandial glucose level in plasma or blood is an important factor for the etiology of non-communicable disorders like the metabolic syndrome, diabetes, obesity and cardiovascular disease. A high sugar content of the food naturally increases the postprandial glucose level. However, quite a few studies provided proof in the past that the physical properties like viscosity, temperature, and water content of the food we consume also may influence the level of this parameter. The aim of this study is to give a narrative review of present findings that showed the physical properties of consumed food influenced the postprandial glucose level.

The online databases Medline, Pubmed, Google Scholar and Hinari have been searched for publications on “plasma glucose” and “temperature” or “viscosity” or “solubility” or “water content”. All articles dealing with the influence on the postprandial glucose level in the blood have been included. Articles written in a language we could not understand or without a proper translation into English have been excluded.

In general, most available studies showed that the physical properties temperature, viscosity, and water content of consumed food influenced the postprandial glucose. An increased temperature, increased viscosity and decreased water content of the food is generally associated with a higher postprandial glucose level in blood or plasma after consumption. Further detailed studies in both preclinical as well as clinical trials should be considered to obtain more detailed results regarding this.
