Abstract

The search for a quality diet has grown over the past decade. Diet is considered one of the pillars for the prevention and progression of several diseases, among them: diabetes. Type 2 diabetes (T2D) is an epidemic of western countries that increases the vulnerability of other diseases, such as cardiovascular and cancer. T2D is associated with lifestyle and diet. The traditional Mediterranean diet has proven its benefits over several cardiovascular risk factors, and specifically on diabetes. This review compiles recent published evidence on the effects of the Mediterranean diet on the incidence and progression of type 2 diabetes (T2D) and its relation with several other cardiovascular healthy diets. We will also focus on how the Mediterranean diet could play a role in T2D-related mechanisms, such as anti-inflammatory or antioxidant compounds, glucagon-like peptide agonist compounds, and changes in gut microbiota. Each component of the Mediterranean diet could be involved in processes related to diabetes homeostasis, many of them sharing common physio-pathological pathways. The importance of this diet within the set of habits of a healthy lifestyle must be emphasized.

  • In patients with type 2 diabetes, the Mediterranean diet can beneficially affect glycemic control and cardiovascular risk.

    “In patients with type 2 diabetes, MD can beneficially affect glycemic control and cardiovascular risk [54, 55].”
  • Increased monounsaturated fatty acids and reduced saturated fatty acids in the diet have been associated with increased insulin sensitivity and improved beta cell function.

    “Increased monounsaturated fatty acids and reduced saturated fatty acids in the diet have been associated with increased insulin sensitivity and improved beta cell function [26,27].”
  • Because the Mediterranean diet is rich in dietary fiber, fermentation of this fiber leads to formation of short-chain fatty acids, which stimulate GLP1 expression.

    “As MD is rich in dietary fiber, and the fermentation of this fiber leads to the formation of SCFAs, these then, in turn, stimulate GLP1 expression [26].”
  • Unlike the Mediterranean diet, for which long-term efficacy and safety have been observed, low-carbohydrate and very-low-carbohydrate diets lack data on long-term safety, adherence, and efficacy.

    “Unlike other dietary patterns such as the Mediterranean diet for which long-term efficacy and safety have been observed [95, 96], low-carbohydrate and very-low-carbohydrate diets lack data on long-term safety, adherence, and efficacy [97].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
