A review of nutrition and dietary interventions in oncology

The complex cellular mechanisms and inter-related pathways of cancer proliferation, evasion, and metastasis remain an emerging field of research. Over the last several decades, nutritional research has prominent role in identifying emerging adjuvant therapies in our fight against cancer. Nutritional and dietary interventions are being explored to improve the morbidity and mortality for cancer patients worldwide. In this review, we examine several dietary interventions and their proposed mechanisms against cancer as well as identifying limitations in the currently available literature. This review provides a comprehensive review of the cancer metabolism, dietary interventions used during cancer treatment, anti metabolic drugs, and their impact on nutritional deficiencies along with a critical review of the following diets: caloric restriction, intermittent fasting, ketogenic diet, Mediterranean diet, Japanese diet, and vegan diet.

Common risk factors for major noncommunicable disease, a systematic overview of reviews and commentary: the implied potential for targeted risk reduction

Noncommunicable disease now contributes to the World Health Organization top 10 causes of death in low-, middle- and high-income countries. Particular examples include stroke, coronary heart disease, dementia and certain cancers. Research linking clinical and lifestyle risk factors to increased risk of noncommunicable disease is now well established with examples of confirmed risk factors, including smoking, physical inactivity, obesity and hypertension. However, despite a need to target our resources to achieve risk reduction, relatively little work has examined the overlap between the risk factors for these main noncommunicable diseases. Our high-level review draws together the evidence in this area. Using a systematic overview of reviews, we demonstrate the likely commonality of established risk factors having an impact on multiple noncommunicable disease outcomes. For example, systematic reviews of the evidence on physical inactivity and poor diet found each to be associated with increased risk of cancers, coronary heart disease, stroke, diabetes mellitus and dementia. We highlight the potential for targeted risk reduction to simultaneously impact multiple noncommunicable disease areas. These relationships now need to be further quantified to allow the most effective development of public health interventions in this area.

Examining Colorectal Cancer Risk Awareness and Food Shelf Use Among Health Center Patients

OBJECTIVE

To employ the Colorectal Cancer Risk Awareness for Public Health Prevention (CRC-PHP) survey to examine how food shelf use and other covariates predict awareness of colorectal cancer (CRC) risk factors among patients of a Federally Qualified Health Center in Minneapolis, Minnesota. Secondary aims included describing the demographic and chronic-disease characteristics of the patient population and assessing their general knowledge of additional CRC risk factors and intent to make healthy food selections in the near future.

METHODS

Measures included CRC risk awareness, food shelf use, chronic-disease status, and intent to select healthy food options. Regression models and chi-square tests of independence were employed to examine differences among food shelf users and non-users.

RESULTS

Among the 103 patients surveyed, 29% reported using a food shelf in the last 12 months. Forty-seven percent of food shelf users and 38% of non-users reported having at least 1 diet-related condition (e.g., type 2 diabetes mellitus). Food shelf users scored 1.2 points higher than non-users, on average, on the CRC risk-factor awareness scale. They also answered more survey questions correctly regarding fruit and vegetable intake and its effect on CRC risk (p = 0.035). Most participants reported being likely to purchase health-promoting foods in the future. In addition, participants reported being likely to select foods that were labeled as protective against CRC.

CONCLUSIONS

Behavioral interventions exist that are focused on preventing and managing type II diabetes among food shelf users. Building off such interventions and incorporating behavioral economics components (such as nudges and product labels) has the potential to reduce food shelf customers' heightened risk and management of CRC.
