The Mediterranean diet demonstrated broad symptomatic improvement in fibromyalgia across multiple domains in an RCT (n=84), including pain, disability, fatigue, anxiety, and depression at 2 months.
The Mediterranean diet is associated with a 47% reduction in GERD odds (OR=0.53) at the highest adherence level. Multiple complementary mechanisms contribute to symptom relief beyond simple acid suppression.
Adherence to the Alternate Mediterranean Diet (AMED) pattern — high in fiber, polyphenols, omega-3 fatty acids, and plant-based foods — as both a preventive and post-diagnosis survival strategy. This is the only dietary pattern with direct overall survival data in OC.
The Mediterranean diet improves glycemic control and cardiovascular risk in T1D youth while promoting butyrate-producing taxa depleted in T1D, particularly F. prausnitzii. Combination with L. johnsonii N6.2 supplementation has been proposed.
