Benefits of Post-diagnosis Plant-Based Diets on Prognosis in Adult Cancer Survivors

Plant-based diets (PBDs) are all the rage these days. This food pattern comprises a diet rich in whole grains, vegetables, fruit, nuts and legumes and limited or no red and processed meat.

Several evidence-based recommendations for the primary prevention of cancer and other non-communicable diseases promote the adoption of PBDs. Although PBDs are recommended for cancer prevention, their role in cancer survivors is unclear.

The authors of this systematic review summarised and reported on the association between post diagnosis plant-based diets and prognosis, especially in breast, colorectal and prostate adult cancer survivors.

They reported that recent studies indicate that:

  1. A higher intake of plant-based foods was associated with improved prognosis in cancer survivors.

  2. A better prognosis was observed when colorectal cancer survivors had a higher intake of whole grains and fibre.

  3. Beneficial outcomes were related to a higher intake of fruit, vegetable and fibre and a moderate intake of soy/isoflavone in breast cancer survivors.

  4. A higher vegetable fat intake was associated with improved prognosis in prostate cancer survivors.
