title: Sugar beet fiber in formula diet reduces postprandial blood glucose, serum insulin and serum hydroxyproline.
abstract: OBJECTIVE
  The object of the study was to investigate the effects of sugar beet fiber in formula diet on blood glucose, serum insulin and serum hydroxyproline in humans.
  
  
  METHODS
  Two formula test meals with and without 7 g of sugar beet fiber, namely 5.1 g total dietary fiber, were ingested on two mornings, in random order, by the subjects.
  
  
  METHODS
  The test meals were served in a clinic to the subjects after a 12 h fast.
  
  
  METHODS
  Fifteen healthy male human volunteers (mean age 25 y, range 21-42) registered to participate in the study after an announcement.
  
  
  METHODS
  The test meals of formulas contained similar amounts of nutrients and gave total energy of 1778 kJ (425 kcal). Blood samples were drawn before and after the test meals. The total test time from the start of ingestion of the meal was 155 min.
  
  
  RESULTS
  The formula with sugar beet fiber reduced the postprandial blood glucose response (P < 0.05), serum insulin response (P < 0.025) and serum hydroxyproline response (P < 0.025), compared with the formula without fiber.
  
  
  CONCLUSIONS
  Sugar beet fiber in a formula could thus reduce hyperglycemia in enteral nutrition and be useful in therapeutic liquid and formula diets. Sugar beet fiber was shown to tolerate preparation for canning well, namely homogenization and heating, and to be capable of diminishing the glycemic responses in the relatively small amount used.
