Adherence to plant-based dietary patterns, specifically the Mediterranean and DASH diets, is associated with significantly lower levels of oxidative stress and pro-inflammatory biomarkers compared to habitual or Western diets.
Focus on adopting a Mediterranean or DASH dietary pattern rather than relying on isolated antioxidant supplements. These patterns, rich in plant-based foods, are consistently linked to lower inflammation and oxidative stress in both observational and intervention studies. Prioritize whole foods over single-nutrient interventions for chronic disease prevention.
Overall, results indicated an inverse association between plant-based diets - the Mediterranean and Dietary Approaches to Stop Hypertension (DASH) diet - and oxidative stress and proinflammatory biomarkers.
Why this rating
Based on a systematic review of 29 studies (16 observational, 13 intervention), though quality of intervention studies was rated low-to-moderate.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
