The results of the meta-analysis presented here support
the recommendation to increase dietary fiber intake in
patients with type 2 diabetes in order to decrease HbA1c
and fasting plasma glucose levels. Thus, these patients
should be encouraged to include in their daily diet foods
that are rich in fiber,such as whole grains,vegetables,and
fruits, or to use fiber supplements. However, considering
the different types and sources of fibers (soluble and/or
insoluble fibers provided by foods and/or supplements),
RCTs should be performed to explore the best sources
and amounts of dietary fiber necessary to improve
glycemic control in patients with type 2 diabetes
