There are two dietary treatments for NDs, the Mediterranean diet (MedD) and the ketogenic diet (KD). MedD is a dietary pattern rich in antioxidants and unsaturated fatty acids, which has neuroprotective effects such as regulating GM and metabolite composition, anti-inflammatory, antioxidant and reduce pathological proteins. And there are different intake strategies for different foods. KD is a high fat, low carbohydrate, appropriate protein and nutrients dietary pattern. Neuroprotective mechanisms may involve regulation of GM and metabolite composition, anti-inflammatory, antioxidant, and epigenetic. However, long-term low carbon water intake can cause certain side effects, such as gastrointestinal, weakness, inattention, myodynia and decreased bone density. HbA1c, hemoglobin A1C. CRP, C-reactive protein.
