Liebe LOGIanerInnen!
Eine neue Metaanalyse zum Effekt von Low-Carb bei Diabetes ist gerade veröffentlicht worden. Das Ergebnis: Günstig für die Blutzuckerkontrolle und günstig für die Blutfette. Und es gibt einen signifikanten Zusammenhang: Je niedriger die Khs, desto niedriger das HbA1c.
Kirk, JK et al. Restricted-Carbohydrate Diets in Patients with Type 2 Diabetes: A Meta-Analysis. J Am Diet Assoc. 2008;108:91-100.
ABSTRACT
Many current popular weight-loss diets advocate restricting
carbohydrates, but risks and benefits of these diets for patients
with diabetes is unclear. We searched for articles
published in English between 1980 and April 2006 regarding
carbohydrate-restricted diets that included and reported
separate results for adult, nonpregnant patients
with type 2 diabetes. Articles were limited to studies completed
in the United States and Canada. Available data on
study design; carbohydrate composition of diet; duration of
diet; and the outcomes of weight, lipid levels (total, lowdensity
lipoprotein and high-density lipoprotein cholesterol,
and triglycerides), hemoglobin A1c percent and/or fasting
glucose were extracted. A total of 56 studies or reviews were
evaluated. Thirteen studies met our inclusion criteria.
Meta-regression analyses show that hemoglobin A1c, fasting
glucose, and some lipid fractions (triglycerides) improved
with lower carbohydrate content diets. Overall effect
on weight was equivocal among the studies evaluated in
this meta-analysis. Randomized, controlled studies of restricted-
carbohydrate diets in patients with diabetes need to be conducted
in order to evaluate the overall sustainability
of outcomes and long-term safety.
