G, et al. – The present study sought to compare the impacts of
Mediterranean and Vegetarian diets on several anthropometric and
circulating cardiovascular biomarkers. Results of this study suggested
that both Mediterranean and Vegetarian dietary patterns appear to be
equally effective in diminishing anthropometric parameters among
clinically healthy subjects, but Vegetarian diet determined a
significant reduction of total cholesterol, LDL cholesterol and insulin
levels, while Mediterranean diet determined a significant reduction of
triglycerides.
Methods
- For the purpose of this study, 88 clinically healthy subjects (68 F; 20 M; mean age: 50.7 ± 12.9) were randomly allocated to Mediterranean (Med) or Vegetarian (Veg) isocaloric diets lasting 3 months each, and then crossed over.
- After that, adherence to the specific dietary intervention was established through questionnaires and 24–h dietary recall.
- Finally, anthropometric measurements, body composition and blood sampling were obtained from each member toward the start and toward the finish of each intervention phase.
Results
- At the end of the 3–months intervention phase, Med and Veg both determined a significant (p<0.05) decrease of total body weight, fat mass and BMI, without any significant difference between the 2 diets [body weight: –2.0 kg (–2.5%) vs. –2.4 kg (–3.0%)], [fat mass: –1.8 kg (–6.1%) vs. –1.6 kg (–5.6%)] [BMI: –0.7 kg/m2 (–2.4%) vs. –0.8 kg/m2 (–2.8%)], for Med and Veg, respectively.
- With regard to circulating biomarkers, Veg determined a significant (p<0.05) diminish for total cholesterol [–6.0 mg/dL (–2.9%)], LDL cholesterol [–6.5 mg/dl (–5.1%)] and insulin levels [–0.7 mU/L (–6.9%)], while Med determined a significant decrease of triglycerides [–11 mg/dL (–8.9%)].
