Men diagnosed with prostate cancer are generally advised to avoid lifestyle habits that promote systemic inflammation, obesity, and accelerated disease progression. Clinicians recommend limiting the consumption of excessive red meats, highly processed foods, sugary beverages, and trans fats, while moderating dietary calcium and alcohol intake. Additionally, smoking cessation is strongly emphasized, as tobacco use worsens overall health outcomes and complicates recovery from oncological treatments. Maintaining a balanced, nutrient-dense diet rich in plant-based foods, antioxidants, and regular physical activity is vital for supporting overall well-being during and after therapy.
