Your gut microbiome is like a quiet garden inside you: when it’s balanced and well-fed, inflammation calms down, immunity strengthens, and even mood and energy lift. For anyone with lupus or autoimmunity, this matters even more, because a healthy gut helps keep the immune system from overreacting. Eating a daily mix of colorful plants, fermented foods, prebiotic fibers (think garlic, onions, oats, berries), and staying low on processed sugar and junk oils is the simplest, kindest way to nourish that garden and give your body the support it needs to feel better, day after day.
