Nutrition plays a pivotal role in addiction recovery, aiding physical and mental health restoration. Substance use often leads to nutrient deficiencies, weakening the immune system and impairing cognitive function. A balanced diet replenishes essential vitamins and minerals, enhancing the body's natural detoxification processes. Specific nutrients like omega-3 fatty acids support brain health, while proteins aid neurotransmitter repair. Incorporating whole foods, lean proteins, and hydration in recovery plans improves mood, reduces cravings, and strengthens overall resilience. Dietitians and addiction specialists can design tailored nutritional strategies to complement treatment, making healthy eating habits a cornerstone of long-term recovery.
