Systemic inflammation and diet play significant roles in fitness. Chronic inflammation can impede recovery and performance, while a diet rich in anti-inflammatory foods (like fruits, vegetables, and omega-3 fatty acids) can help reduce inflammation. Nutrient-dense foods provide essential vitamins and minerals that support muscle function and recovery. Conversely, excessive consumption of processed foods can contribute to inflammation, negatively impacting fitness levels. Balancing dietary choices is crucial for maintaining optimal health and maximizing fitness potential.
