The Mediterranean diet is often hailed as a ‘healthy diet’ but what about in cancer? Read on to find out if there are any benefits to the ‘Mediterranean diet after cancer.

Understanding the Mediterranean Diet

Mediterranean Diet after cancer

The Mediterranean diet is inspired by traditional eating patterns of countries bordering the Mediterranean Sea. It emphasizes whole, minimally processed foods rich in fruits and vegetables, olive oil, nuts, wholegrain, beans, pulses and plant-based food. Smaller amounts of red and processed meats as well as some diary, oily fish, and chicken.

The research into people following a Mediterranean diet has shown it is linked to improved cardiovascular health, lower risk of Type 2 diabetes and reduced risk of some cancers. Let’s look at that a bit closer.

The Link Between Mediterranean Diet and Cancer

Lots of studies have investigated the relationship between the Mediterranean diet and cancer prevention and recovery. As the diet’s focus on fresh fruits, vegetables, and whole grains this provides a rich source of vitamins, minerals, and antioxidants, which are known to support the body’s immune system and help combat cancer cells.

Olive oil, a feature of the Mediterranean diet, contains monounsaturated fats and polyphenols that have anti-inflammatory and antioxidant properties. Fish, is another core component of the Mediterranean diet, is a great source of omega-3 fatty acids, which have been associated with a reduced risk of certain cancers and may help manage inflammation.

One study investigated patients with in advanced skin cancer on immunotherapy treatment. Patients who were advised to follow a Mediterranean diet had improved response to treatment. This is promising but it’s worth noting that this was a small study; only 91 people so further research needed particularly in other cancer groups as we can’t say that this could improve treatment response in other cancers 1.

Is it all about food?

The Mediterranean diet also has another aspect- lifestyle particularly physical activity, as well as getting adequate rest and socialising with friends and family. Interesting there has been some new research looking at not only diet but the lifestyle aspects of the Mediterranean diet too. A new UK prospective study looked at people following a Mediterranean diet and risk of cancer. Those following more aspects- diet and exercise had a 30% lower risk of cancer. But it’s important to remember this study only shows interesting associations or links between cancer and nutrition not causality 2.
