Other studies that assessed cortical GSH levels by proton magnetic resonance spectroscopy suggested that GSH may be a biomarker of depression, with lower levels in patients with major depression (Godlewska et al., 2015
One mechanism by which butyrate may function is to inhibit the activation of the proinflammatory cellsignaling component nuclear factor kappa B (NF-kB) (Segain 2000)

Your daily nutrition should include: High-Fiber Foods for GLP-1 Production: Vegetables : Artichokes, asparagus, Brussels sprouts, broccoli, and leafy greens (aim for 7-9 servings daily) Resistant Starch Sources : Cooked and cooled potatoes, green bananas, and legumes Prebiotic-Rich Foods : Onions, garlic, leeks, Jerusalem artichokes, and dandelion greens Whole Grains : Oats (especially for beta-glucan), quinoa, and barley Legumes : Lentils, chickpeas, and black beans (excellent for both fiber and protein) Healthy Fats for Satiety and GLP-1 Support: Olive oil, rich in oleic acid and 2-Oleoyl Glycerol (2-OG), has been shown to support natural GLP-1 production Extra virgin olive oil (use liberally in cooking and dressings) Avocados and avocado oil Nuts and seeds (especially walnuts, flaxseeds, and chia seeds) Fatty fish rich in omega-3s (wild salmon, sardines, mackerel) Fermented Foods for Microbiome Diversity: Foods like yogurt, kefir, kimchi, and sauerkraut support a balanced gut microbiome and regular consumption introduces beneficial bacteria that may naturally boost GLP-1 Kefir (dairy or coconut-based) Kimchi and sauerkraut Kombucha (unsweetened) Miso and tempeh Plain, full-fat yogurt with live cultures Protein Strategy for Muscle Preservation: Aim for 1.2-1.5 grams of protein per kilogram of body weight daily, distributed across meals: Lean proteins: Wild-caught fish, organic poultry, grass-fed beef Plant proteins: Legumes, quinoa, hemp seeds, spirulina Consider collagen peptides for additional support 2
