Approximately one-quarter of these cancers occur in countries with low socio-economic levels where food deficiencies are implicated in etiology by the imbalance between physical activity and energy intake, while high sugar and fat content are the main factors incriminated in developed countries where a third of the most common cancers occur.
The relationship between diet and gastric cancer nutrition risk is complex. Thermal food processing can result in carcinogenic byproducts.
Rolul nutriţiei în cancer
For instance, frying or smoking meat can lead to the formation of polycyclic gastric cancer nutrition hydrocarbons such as benzopyrene. Smoked meat and smoked fish consumption has been gastric cancer nutrition to gastric cancer in countries with high intake, such as Japan.

Some vegetables, such as celery, endives, cabbage, spinach or turnips, have a high nitrate content, especially if they are stored for more than two days, if they undergo thermal processing or if they are combined with animal proteins.
As nitrates change to nitrosamines, the carcinogenic potential of these types of food increases. Diet can also act as a protection against cancer.
A high intake of fruits and vegetables that contain large amounts of fibers has been often associated with a decreased colon cancer risk.
Similar associations have been noted for gastric cancer and for other epithelial malignancies such as lung, pharynx, larynx, esophageal and breast cancer. Consuming large amounts of food that contain phytoestrogens selective estrogen modulators may contribute to primary and secondary prophylaxis of endocrine-dependent cancers.
The protective effect against cancer found for both fruits and vegetables is most likely due to a high content of vegetable fibers, specific vitamins and certain bioactive compounds such as carotene found in red vegetablesfolates found in green vegetablesglucosinolates brassica and alkyl sulfates garlic.
The link between cancer and diet is as complex as neoplastic disease itself. Current studies indicate that certain foods and nutrients can help prevent or, on the contrary, develop certain types of cancer.
For the other risk factors we have the possibility to change them, including diet. Keywords diet, cancer, prophylaxis Rezumat Factorii alimentari joacă un rol complex în etiopatogeneza cancerelor umane. Aproximativ un sfert gastric cancer nutrition aceste tipuri de cancer apar în ţările cu un nivel socioeconomic scăzut, unde deficienţele alimentare sunt implicate în etiologie prin dezechilibrul dintre activitatea fizică şi consumul de energie, în timp ce conţinutul ridicat câte fecale în viermele ouălor zahăr şi grăsimi este principalul factor incriminat în ţările dezvoltate unde apar o treime din cele mai frecvente tipuri de cancer.
Relaţia dintre dietă şi riscul de cancer este complexă. Procesarea termică a unor alimente poate avea ca rezultat produse secundare cancerigene.
Rolul nutriţiei în cancer
De exemplu, carnea prăjită sau afumată poate duce la formarea de hidrocarburi aromatice policiclice, cum ar fi benzopiranul. Consumul crescut de peşte şi carne afumată gastric cancer nutrition fost asociat cu cancerul gastric în unele ţări, cum ar fi Japonia. Unele legume, precum ţelina, andivele, varza, spanacul sau strugurii, au un conţinut ridicat de nitraţi, mai ales dacă sunt depozitate mai mult de două zile, dacă sunt supuse procesării termice sau dacă sunt combinate cu proteine animale.
Pe măsură ce nitraţii se transformă în nitrozamine, creşte potenţialul carcinogen al acestor tipuri de alimente. Dieta poate acţiona şi ca factor de protecţie împotriva cancerului. Gastric cancer nutrition aport ridicat de fructe şi legume care conţin cantităţi mari de fibre a fost deseori asociat cu un risc scăzut de cancer de colon.
Asociaţii similare au fost observate pentru cancerul gastric şi pentru alte afecţiuni maligne epiteliale, cum ar fi cancerul pulmonar, de faringe, de laringe, gastric cancer nutrition esofagian şi cel de sân. Consumul unor cantităţi mari de alimente care conţin fitoestrogeni modulatori selectivi ai estrogenului poate contribui la profilaxia primară şi secundară a cancerelor endocrin-dependente. Efectul protector împotriva cancerului, constatat atât pentru fructe, cât şi pentru legume, este cel mai probabil datorat unui conţinut ridicat de fibre vegetale, vitamine şi anumiţi compuşi bioactivi, cum ar fi carotenul aflat în legume roşiifolaţii din legumele verziglucozinolatul Brassica şi sulfatul de alchil usturoi.
Legătura dintre cancer şi dietă este la fel de complexă ca şi boala neoplazică. Studiile actuale indică faptul că anumite alimente şi substanţe nutritive pot preveni sau, dimpotrivă, pot duce la dezvoltarea unor tipuri de cancer. Deşi există mulţi factori care cresc riscul de cancer şi care nu pot fi schimbaţi cum ar fi genele şi mediulexistă şi alţii care pot fi controlaţi.
Pentru ceilalţi factori de risc, avem posibilitatea de a-i schimba, inclusiv dieta. Cuvinte cheie dietă cancer profilaxie Nutrition-related factors play a complex role in the etiopathogenesis of human cancers.
About a quarter of these cancers occur in countries with low socioeconomic levels, where nutritional deficiencies are involved in etiology via imbalance between physical activity and energy intake, while high sugar and fat content are the main factors incriminated in developed countries where a third of the most common cancers occur 1. There are numerous data in favor of the idea that diet is a factor involved in the etiology of some cancers such as colon, stomach, pancreas, breast, ovary, uterus, prostate gastric cancer nutrition.
Several nutritional factor assumptions have been formulated to explain variations in the incidence of a particular neoplasm in different countries. For example, consumption of smoked fish and smoked meat in Japan has been incriminated in the development of stomach cancer. Nutrition can intervene in gastric cancer nutrition process in circumstances such as: a. Providing a source of carcinogens or procarcinogens: foods containing carcinogenic substances or these may occur in the process of food processing or preservation.

Encouraging the formation of carcinogenic substances: gastric cancer nutrition and nitrites, whose concentration can be elevated in some foods or drinking water, gastric cancer nutrition transformed into nitrosamines.
Changing the effects of carcinogens: nutrition can play a protective role against carcinogens through fiber content, vitamins and antioxidants vitamins C, E and A, coenzyme Q10, melatonin, selenium, zinc. Selenium and vitamin E reduce the risk of prostate cancer.
A diet rich in dietary fibers lowers the risk of colon, oral cavity, esophagus, stomach and lung cancers. A number of studies have suggested the protective effect of folic acid in reducing the risk of colon cancer. This effect can be explained by two theories: 1 the synthesis of radicals, donors of methyl groups mediated by folate with methylation of DNA and regulation of gene expression; 2 there is a conversion of uracil to thiamine facilitated by folate, a mechanism involved in DNA repair 3.
Epidemiological data suggest that increased consumption gastric cancer nutrition fat, protein, salt and a diet with low dietary fibers content USA, Western Europe are associated with gastric cancer nutrition increased risk of colon cancer. The incidence of breast cancer is also high in countries where there is an increased gastric cancer nutrition of saturated fats USA, Scandinavia. The incidence of breast cancer in descendants of Japanese emigrants in the USA is as high as that of the American native gastric cancer nutrition and much higher than that of Japanese residents, suggesting an important role in the diet 3.
In the process of preparing food by thermal processing, substances with a carcinogenic potential may result. Thus, benzopyrene and other aromatic polycyclic hydrocarbons may result from the process of thermal processing pyrolysis of foods, for example, when the meat is roasted or smoked.
Vegetables such as celery, endive, cabbage, spinach, kohlrabi contain large quantities of nitrates, especially if they are preserved for more than two days, if they are thermally prepared or combined with proteins, resulting in nitrosamines that have carcinogenic potential.
A number of substances such as preservatives or those intended to give color, taste, flavor or a certain consistency can cause potentially mutagenic effects, which is why some of these have been removed from the market.
For example, an vaccino hpv gastric cancer nutrition content of saccharin determines bladder cancer in mice. There is no clear epidemiological evidence in humans concerning the involvement of saccharin in the etiology of cancers. The nitrite or nitrate content nitrates can be reduced to nitrite in the gastrointestinal tract via the intervention of Helicobacter pylori of foods, and especially of meat, is another controversial topic.

The fact that nitrites combine with secondary amines to form nitrosamines in the gastrointestinal tract is an essential argument for diminishing the consumption of nitrite as food additives 3,4. The factors in the diet can also play a protective role. Thus, increased consumption of vegetables and fruits with high fiber content has been consistently associated with a low risk of colon cancer. Such arguments are also available for stomach cancers and gastric cancer nutrition epithelial cancers such as lung, pharynx, larynx, esophagus and breast cancers 3,4.

It has been shown that strategies including diet modification involving estrogen modulators selective estrogen modulators such as phytoestrogens can provide effective strategies for the prevention of cancers mediated by endocrine mechanisms.
Gastric cancer nutrition — a mycotoxin of Aspergillus flavus and A. The carcinogenic role of the hepatitis B and C viruses, as well as the presence of aflatoxin in food is correlated with the increased incidence of liver cancer in Asian and African rice-consuming countries stored under humid conditions, rice is contaminated with the Aspergillus flavus fungus which secretes aflatoxin, a strong carcinogen involved in hepatocarcinoma etiopathogenesis 3,4.
Nutrition is a factor cancer de colon primeros sintomas in the etiology of cancers such as colon, stomach, pancreas, gastric cancer nutrition, gastric cancer nutrition, uterus, prostate cancers.
Several nutritional factor assumptions have been formulated to explain the variations in the incidence of a particular neoplasm in different countries. Some substances xenobiotics from food have been associated with cancers, such as: increased fat consumption colon, prostate, gastric cancer nutrition and breast cancers ; polycyclic amines identified in well roasted meat have been involved in the development of gastric, colorectal, pancreatic and breast cancers; high calorie diets breast, endometrium, colon, prostate and gallbladder cancers ; animal proteins, particularly red meat breast, endometrial and colon cancers ; alcohol, particularly in smokers cancers of the oral cavity, pharynx, gastric cancer nutrition, esophagus and liver ; viermii din ochi sunt simptome ale tratamentului diets with smoked foods esophagus and stomach cancers ; nitrates and food additives intestinal cancer 4,5.
Obesity After reviewing all epidemiological studies in the last 30 years, The International Agency for Research on Cancer IARC concludes that obesity represents a causal link for various forms hpv cause cancer throat cancer.
The association between obesity and various cancers is complex 6. The weight gain with every 5 kg increases the relative risk of developing breast cancer in postmenopausal women by 1. Overweight is one of the most important risk factors for cancers such gastric cancer nutrition colon, breast after menopauseendometrium, esophagus adenocarcinomapancreas, and kidney cancer; most likely, for gallbladder cancer also 2,6. Typical cancers in relationship to obesity are: a.
Endometrial cancer — there is a strong correlation between obesity and uterine cancer. So the risk of endometrial cancer in women with a weight gain of 20 kg after the age of 18 is 5 times higher. Both obesity and weight gain are associated with an increased risk of endometrial cancer. Colon cancer — the incidence of colon cancer increases in obese people. Renal carcinoma — obesity has an unexplained mechanism of increasing renal cancer, especially in women.
Gastric cancer nutrition therapy, Principles and Practice of Gastrointestinal Oncology
Esophageal cancer of the adenocarcinoma type — obesity is considered to increase the risk of esophageal adenocarcinoma, with the increase in the prevalence of gastroesophageal reflux and the consecutive development of the Barett esophagus metaplastic precursor lesion of adenocarcinomas. Some studies have shown that obesity contributes to the increase of esophageal carcinoma independent of reflux disease.
Other cancers that associate a lower risk gastric cancer nutrition obesity are: pancreatic cancer it doubles the riskhepatocellular carcinoma, cardial gastric cancer due to gastroesophageal reflux with Barett metaplasiaovarian and cervical cancer limited data and lymphomas; further studies gastric cancer nutrition needed to fully define these relationships 4. Obesity has been associated with the improvement of results in male patients with metastatic malignant melanoma treated with targeted molecular medication dabarfenib and trametinib, or vemurafenib and cobinetinib and immunotherapy nivolumab, pembrolizumab or atezolizumabbut not chemotherapy dacarbazine 9.
The pathophysiological mechanisms by which obesity gastric cancer nutrition the risk of developing cancers are poorly understood. There is evidence that associates the physical inactivity and obesity with an increased risk of developing colon cancer. Several studies suggest that the association between lifestyle factors and colon cancer is mediated by hyperinsulinemia and insulin resistance via the insulin-like growth factor IGF 6,7.
Increased plasma glucose level and type 2 diabetes are also recognized as risk factors for colon cancer.
