1. Breast cancer: Due to its high antioxidants and healthy fats.

2. Colorectal cancer: Fiber-rich foods, like fruits and vegetables, are key.

3. Prostate cancer: Omega-3 fatty acids and tomatoes may lower risk.

4. Lung cancer: Antioxidants from fruits and vegetables may protect cells.

5. Mouth and throat cancer: Anti-inflammatory foods help reduce risk.

Protective dietary patterns include:

• High consumption of fruits, vegetables, whole grains, and healthy fats (e.g., olive oil).

• Low intake of red and processed meats, added sugars, and unhealthy fats.

Higher diet quality reduces cancer risk

Here are some types of cancer that the Mediterranean Diet may help prevent:

- Colorectal Cancer: High fiber intake from whole grains, legumes, and vegetables supports gut health and reduces inflammation, lowering the risk of colon cancer. 

- Breast Cancer: Olive oil and nuts, rich in healthy fats and polyphenols, have been linked to a reduced risk of breast cancer, particularly in women following a traditional Mediterranean diet.

- Prostate Cancer: Lycopene from tomatoes and omega-3 fatty acids from fish have protective effects against prostate cancer development. 

- Gastric Cancer – The high consumption of fresh fruits, vegetables, and olive oil reduces oxidative stress and protects the stomach lining from carcinogens. 

-Lung Cancer: The diet’s antioxidant-rich foods, including berries, nuts, and leafy greens, help combat cellular damage that can lead to lung cancer.

This review explores how the Mediterranean diet can impact the most common types of cancer and highlight the specific nutrients in the diet that may help lower the risk of cancer.

Olive oil (extra virgin)
Fatty fish (salmon, sardines)
Nuts & seeds (walnuts, flaxseeds)
Leafy greens (spinach, kale)
Berries (strawberries, blueberries)
Tomatoes (rich in lycopene)
Whole grains (quinoa, brown rice)
Legumes (lentils, chickpeas)

- Colorectal cancer – High fiber intake from plant-based foods supports gut health and reduces inflammation.

- Breast cancer – Healthy fats, antioxidants, and reduced processed food consumption help lower risk, especially in postmenopausal women.

- Prostate cancer – Lycopene-rich foods (like tomatoes) and healthy fats may slow progression.

- Gastric (stomach) cancer – A diet low in processed meats and high in antioxidants helps protect stomach lining.

- Liver cancer – Anti-inflammatory properties of the diet support liver health and reduce oxidative stress.

Overall, the Mediterranean diet's emphasis on natural, unprocessed foods helps reduce inflammation and oxidative damage, key factors in cancer prevention.

1. Olive Oil (especially extra virgin)

Evidence: A 2022 review in Cancers journal highlights olive oil’s role in modulating gene expression and suppressing tumor growth pathways.

2. Fruits & Vegetables

Evidence: A study in Nutrients (2020) found a strong inverse relationship between high vegetable intake and gastrointestinal cancers.

3. Legumes and Whole Grains

Evidence: EPIC (European Prospective Investigation into Cancer and Nutrition) found whole grain intake inversely related to colorectal cancer incidence.

4. Fish and Omega-3 Fatty Acids

Evidence: Research in The American Journal of Clinical Nutrition (2018) links higher fish intake to lower breast and prostate cancer risk.

5. Moderate Red Wine Consumption

Evidence: While more human studies are needed, lab studies suggest resveratrol affects cancer-related pathways like inflammation, apoptosis, and angiogenesis.

6. Low Red & Processed Meat Intake

Evidence: WHO and numerous meta-analyses confirm high red/processed meat intake is associated with increased colorectal and gastric cancer risk.
