ABSTRACT
@#Gastric and esophageal cancer is a significant global health issue. The epidemiology of these tumors has significantly increased over the past several years especially in developing and developed countries. Many dietary exposures have been proposed to protect against or increase risk for esophageal and gastrointestinal (GI) cancers, including poor diets, foods, individual nutrients, methods of food preparation, and habits of consumption. Overweight/obese status is associated with an increased risk for many cancer types such as esophageal, gallbladder, kidney, pancreatic and gastric cancer. The association between obesity and cancer is strong. Nowadays there is a recognized decrease in incidence and mortality of distal gastric cancer and an increase in incidence and mortality of proximal esophageal cancer. In Mongolia, gastric cancer is the second most common cancer in males and the third most common in females. It is very important to understand how diet and nutrition affect to gastric and esophageal cancers. In this review we will discuss the effect of diet in locally advanced gastro-esophageal cancer. Although we tried to conclude all published articles about gastric and esophageal cancers in Mongolia. </br> In this survey, is considered dietary risks into 5 groups as following; </br> • Insufficient nutrition education(don’t know food and nutrients significance and food hygiene, don’t know right consumption of food) </br> • Bad habits (hot tea and meals, salty tea and food, low consumption of fruits and vegetables, sometimes eating breakfast, most of daily energy of food in the night, high amount of sugar, a drink of caffeine, overweight and etc.) </br> • Food processing technology (such as overcooking, pickling, preserving, frying, excessive salt in tea fried and etc). </br> • Chemical contaminants in food products (various inorganic fertilizers, heavy metals and etc.) </br> • Household economic capacity is influencing</br> Diet can be used as a tool to evoke the positive/desirable biological responses of an organism aiming to maximize health and protection against diseases (chronic/non-communicable diseasesparticularly cancer) by mostly means of prevention.
ABSTRACT
The efficacy and benefits of ketogenic diets (KD) have recently been gaining worldwide and remain a controversial topic in oncology. This systematic review therefore presents and evaluates the clinical evidence on isocaloric KD dietary regimes and reveals that evidence supporting the effects of isocaloric ketogenic dietary regimes on tumor development and progression as well as reduction in side effects of cancer therapy is missing. Furthermore, an array of potential side effects should be carefully considered before applying KD to cancer patients. In regard to counseling cancer patients considering a KD, more robust and consistent clinical evidence is necessary before the KD can be recommended for any single cancer diagnosis or as an adjunct therapy.

BACKGROUND: Many cancer patients use cancer diets. MATERIALS AND METHODS: We listed 13 cancer diets simulating an internet search for which we systematically reviewed clinical data. In the next step we derived recommendations on counseling patients using a Delphi process. RESULTS: We evaluated the following diets: raw vegetables and fruits, alkaline diet, macrobiotics, Gerson's regime, Budwig's and low carbohydrate or ketogenic diet. We did not find clinical evidence supporting any of the diets. Furthermore, case reports and pre-clinical data point to the potential harm of some of these diets. From published recommendations on counseling on complementary and alternative medicine, we were able to derive 14 recommendations for counseling on cancer diets. CONCLUSION: Considering the lack of evidence of benefits from cancer diets and potential harm by malnutrition, oncologists should engage more in counseling cancer patients on such diets. Our recommendations could be helpful in this process.
