Risk factors
Urothelial cancer (bladder cancer) is influenced by many factors: smoking, occupational exposures (paints, aromatic amines), chronic infections, obesity, and, last but not least, dietary factors.
Western diets vs. Mediterranean diet
Diets high in processed meat and saturated fat (typical "western diets") have been found to be associated with an increased risk of bladder cancer, due to the presence of mutagenic substances that, after being filtered, come into contact with the urothelium.
In contrast, the Mediterranean diet-rich in fruits, vegetables, legumes, fish, olive oil and whole grains-is associated with a significantly reduced risk; individual beneficial foods include: olive oil (up to 50 percent reduction), vegetables (cruciferous, carotenoids, polyphenols), legumes and fish.

Role of hydration
Adequate hydration appears to provide an additional barrier: drinking frequently and copiously dilutes urine and promotes the expulsion of potential carcinogens by reducing contact time with the urothelium. Many oncology physicians therefore recommend increasing water intake to prevent or limit the progression of bladder cancer.
Practical strategies in line with the Mediterranean diet
1. Fruits and vegetables: Prefer antioxidant-rich fruits (apples, citrus fruits, berries) and cruciferous vegetables.
2.Legumes and whole grains: Good source of fiber, plant protein and vitamins, promote natural metabolic balance.
3.Olive oil: Prefer cold-pressed-its monounsaturated fatty acids and antioxidants reduce the risk by up to 50 percent.
4.Fish and plant protein: Replace red and processed meat with fish, legumes, nuts.
5.Constant hydration: At least 1.5-2 liters of water daily, in the absence of medical contraindications.

Conclusions
A well-balanced Mediterranean diet -- enriched with vegetables, legumes, fish, and olive oil -- and good regular hydration provide a good dietary "shield" against the development of urothelial cancer. These strategies, supported by numerous epidemiological and biological studies, should complement-not replace-classical preventive measures.
