Long-term cancer survivors represent a sizeable portion of the population. Plant-based foods may enhance the prevention of cancer-related outcomes in these patients. We aimed to synthesize the current evidence regarding the impact of plant-based dietary patterns PBDPs on cancer-related outcomes in the general population and in cancer survivors. Considered outcomes included overall cancer mortality, cancer-specific mortality, and cancer recurrence. Pooled estimates of the associations between the aforementioned PBDPs and the different cancer outcomes were obtained by applying random effects meta-analysis. The few studies available on the vegetarian diet failed to support its prevention potential against overall cancer mortality when compared with a non-vegetarian diet e. The insufficient number of studies evaluating provegetarian index scores in relation to cancer mortality did not permit a comprehensive assessment of this association. The association between adherence to the Mediterranean diet and cancer mortality reached statistical significance e. However, no study considered the influence of prognostic factors on the associations. In contrast, post-diagnostic studies accounted for prognostic factors when assessing the chemoprevention potential of PBDPs, but also were inconclusive due to the limited number of studies on well-defined plant-based diets.
However, each patient endured dark phases during their treatment, from serious financial difficulties, broken relationships, and the most devastating of it all — no results. The intervention study was not considered for the meta-analysis due to its different nature. Adjustment variables included many potential confounders related with medical conditions, as well as body mass index BMI.
She offers some great insights into the benefits of eating a plant-based diet. The number of cancer survivors has increased over the years due to better screening and treatment. As of January , there were an estimated By , the number of cancer survivors is projected to increase by Nutrition plays an important role during and after cancer treatments. Following a mostly plant-based diet is advised. However, what you eat varies depending on where you are on your cancer journey. Cancer treatment may include chemotherapy, radiation therapy, surgery or immunotherapy — all of which factor into what you eat and drink. Sticking to a plant-based diet may be hard. Diet during treatment is usually focused on easing side effects, minimizing weight loss and preventing dehydration. Good habits also help rebuild muscle loss, promote bone health, and improve overall quality of life. Eating a mostly plant-based diet will help you reach these goals.
Scoring is reversed for all other animal-based foods. Points assigned by quintiles 1 to 5 of consumption, whereby fruits, vegetables, nuts, cereals, legumes, olive oil, and potatoes are positive components, and animal fats, eggs, fish, dairy products, and meats or meat products are negative components scoring reversed. There is confusion over soy consumption and its possible link to breast cancer. No Shinkei Geka. Conclusions This review and meta-analysis of the current available evidence on the association between PBDPs and cancer mortality show that there is limited evidence regarding the beneficial effects of vegetarian diets for the prevention of cancer-related outcomes in the general population and in cancer survivors. Received Jun 10; Accepted Jul 2. Based on the responses to a finite list of foods, participants were classified into vegetarians and vegans in most studies; only the study by Orlich based this classification upon a validated FFQ [ 61 ]. Recently, a priori-defined plant-based scores have been proposed to allow comparisons between different levels of compliance with vegetable-derived foods against animal-derived foods [ 53 ].
