Adherence to the Rainbow Diet helps prevent cardiovascular disease, Type-2 diabetes, obesity and metabolic syndrome

The colourful Mediterranean Diet, or Rainbow Diet, has moderate to high evidence that it has a beneficial effect on type-2 diabetes, cardiovascular disease, metabolic syndrome and obesity, according to a clinical-level meta-analysis (1).

The purpose of the study was to apply a clinical-standard review to the various research studies and claims for the diet.

A systematic review was formulated to answer 5 Clinical Questions. An original review using 37 studies was complemented with a further 20 studies reported on between September 2013 and July 2016.

Researchers concluded that:

  1. There is a high level of evidence showing that adherence to the Rainbow Diet
    a. plays a role in the primary and secondary prevention of cardiovascular disease (CVD), and,
    b. Improves health in overweight and obese patients.
  2. There is moderate-to-high evidence that adherence to the Rainbow Diet
    a. prevents increases in weight and waist circumference in non-obese individuals, and,
    b. improves metabolic syndrome and reduces its incidence.
  3. There is moderate evidence that the adherence to the Rainbow Diet
    a. plays primary and secondary roles in the prevention of type 2 diabetes mellitus.

The colourful Mediterranean Diet is effective in preventing obesity and Metabolic Syndrome in healthy and at-risk
individuals, in reducing mortality risk in overweight or obese individuals, in decreasing the incidence of type-2 diabetes and cardiovascular disease in healthy individuals, and in reducing symptom severity in individuals with either or both.
