A Complete Guide About Bladder Cancer Diet
The significance of nutrition is non-negotiable for living a healthy life. For those with bladder cancer, however, the importance of a balanced and nutritious diet becomes even more crucial. Balanced consumption of vegetables, fruits, proteins, and fats can support treatment and may help in preventing the progression of bladder cancer.
What is bladder cancer?
Bladder cancer is a relatively rare form of cancer that begins in the lining of the bladder. The bladder is a hollow, muscular organ located in the pelvis. Its primary function is to store urine, which it receives from the kidneys via tubes called ureters.
Bladder cancer occurs when the tissue lining mutates and develops abnormal cells that multiply to form tumours. If left untreated, bladder cancer may spread to nearby lymph nodes and other parts of the body, such as the lungs, liver, and bones.
What is the Best Diet for Bladder Cancer?
There is no "one-size-fits-all" diet for individuals with bladder cancer. However, medical professionals recommend including the following food categories, which have shown benefits in many patients:
- Fruits and Vegetables: Vegetables such as carrots, cauliflower, mushrooms, and leafy greens are rich in essential vitamins and minerals, and they help maintain a healthy digestive system. Additionally, antioxidant-rich fruits like berries, pomegranates, apples, tomatoes, and walnuts help reduce oxidative stress during cancer treatment.
- Whole Grains and Dietary Fibre: A high-fibre diet containing whole grains such as brown rice, barley, and oats can help prevent diarrhoea and constipation, which are common side effects of bladder cancer treatment. These foods also provide sustained energy, helping reduce fatigue during treatment.
- Healthy Fats: Incorporating healthy fats, such as those found in olive oil, avocados, and fatty fish, supports cell health. These contain monounsaturated and polyunsaturated fats, known for their anti-inflammatory properties.
- Lean Protein: Lean protein sources like fish, turkey, and eggs, along with plant-based options such as soya beans, tofu, and lentils, aid in tissue repair. They also help maintain muscle mass and support immune function during cancer treatment.
Which Foods to Avoid for Bladder Cancer?
Here is a list of foods that patients with bladder cancer need to avoid:
- Red meats and processed meats: Studies suggest that red and processed meat products may increase the risk of bladder cancer. The link between red meat and bladder cancer is not fully understood but is thought to be related to carcinogenic compounds that can form when meat is cooked at high temperatures, rather than its acidity.
- Sugary Drinks: Sugary drinks contribute to obesity, a major risk factor for bladder cancer. Their high glycaemic index causes blood sugar spikes, which trigger insulin surges and may promote abnormal cell growth.
- Food Rich in Saturated Fats: Diets high in saturated fats are associated with inflammation and obesity, which are risk factors for many health problems, including some cancers. It's best to limit these fats for overall health. These fats can also cause weight gain and inflammation, both of which are associated with various health issues, including cancer.
Tips to Improve Bladder Cancer Diet
Here are some general dietary tips for bladder cancer patients:
- Drink plenty of water and stay well-hydrated.
- Break large meals into smaller, more manageable portions.
- Choose heart-healthy foods.
- Avoid tobacco, alcohol, and excessive caffeine consumption.
Medical professionals agree that nutrient-dense foods are most beneficial for those living with bladder cancer, as they support overall health, aid recovery, and may help manage treatment side effects.
However, since nutritional needs can vary widely based on the stage of cancer, treatment type, and other health factors, it is essential to consult a registered dietitian. They can develop a personalised diet plan tailored to a patient’s unique symptoms, medical history, and lifestyle requirements.
