Scientific research suggests that alcohol, red meat, excess protein and fat, especially animal animals, increase the risk of cancer, and also carries a diet rich in salted products, sugars and highly processed carbohydrates. Check what you do not eat (or at least limit), not to get cancer.
At the end of the 1970s, the idea that the diet had something to do with cancer was considered abstract by most oncologists.” Currently, scientists have no doubt that what we eat can increase the risk of cancer. World Cancer Research Fund (World Cancer Research Fund, WCRF) and the American Institute for Cancer Research (AICR) – the world’s largest organizations researching the impact of lifestyle, including diet, the risk of developing cancer – estimate that genetic predispositions are responsible only 5-10% of cancer cases, but inadequate diet, overweight and obesity, and lack of physical activity – 3-8 times more tumors. Environmental factors have a significant contribution to the development of cancer, confirmed by research on migrants and observations of Asian countries , in which the incidence of cancer increased too fast to be attributed to changes in genesfor example, the incidence of breast and colorectal cancer increased threefold in the second generation of Japanese emigrants to the US, which according to researchers is associated with the takeover of the American lifestyle, including dietary habits.Other studies show that the growing prevalence of Western lifestyle in Asian countries increases the incidence of breast and prostate cancer systematically.
What food is carcinogenic?
Several important cancer risk factors emerge from scientific studies.
Alcohol – it has been confirmed that it increases the risk of mouth, larynx, throat, esophagus, breast, colon cancer in men, probably also colon cancer in women and liver cancer. The risk of developing colon cancer increases by 25% when drinking 2 glasses wine per day or 1/2 liter beer compared to non-drinkers Even low and moderate drinking increases the risk of breast cancer (alcohol changes the metabolism of estrogen).
Salt – a diet rich in salted products increases the risk of nasopharyngeal and stomach tumors. Salt irritates the mucous membrane.
Red meat – confirmed that it increases the risk of colon and rectal cancer, and the results also suggest tumors of the pancreas, lungs, esophagus, stomach, prostate and uterus .The most dangerous are meat preparations (cured meat) – increase the risk of colon cancer by about 36 100 g per day for eating, the heme iron in red meat is a catalyst for the formation of so-called oxidative stress, i.e. inflammatory changes, and therefore carcinogens (N-nitrosamines). Red meat increases insulin concentration and increases insulin resistance. and carbohydrates are formed carcinogens.
Dairy – research suggests that it increases the risk of prostate cancer, but on the other hand, diet with high calcium content reduces the risk of colon cancer.
Fat (total) – its excess may increase the risk of breast cancer in women. Low fiber diet with high fat, especially animal fats (typical Polish diet), promotes higher estrogen concentrations and slower metabolism (excess estrogen is less removed with faeces and reabsorbed into the liver).
Protein – an excess of protein, mainly animal, increases the level of IGF-1 hormone (insulin-like growth factor 1), which makes the cells divide quickly, While in children it causes the body to grow, in adults excessive stimulation of cell division can promote the development of cancer.
Sugars and highly processed carbohydrates – promote overweight, increase the concentration of insulin, which in large quantities is a pro-cancer hormone, and cause insulin resistance, increase inflammation in the body.
Overweight and obesity increase the risk of endometrial, esophageal, pancreas, gall bladder, kidney, breast and colon cancers.The risk of falling ill increases from BMI 23 .Overweight and obesity increase inflammatory changes in the body, which promotes the formation of blood vessels of the tumor and division of its cells.They also induce insulin resistance, and a large amount of this hormone promotes the growth of tumors, promotes proliferation of cancer cells, and makes their death difficult.Overweight and obesity in postmenopausal women increase the production of estrogen, which stimulates the division of tumor cells.
High-fat diet increases the risk of tumor recurrence
Many studies confirm that among the factors that influence the risk of cancer recurrence, the excess of fat in the diet, especially in breast cancer, is of great importance, for example in a US study in postmenopausal women with breast cancer a high-fat diet (mainly fat) In another study in women with breast cancer, the risk of death increased by 40% with each 1000 g of fat consumed per month (low-fat plant diet provides approx. 600 g fat, typical Polish diet – ok 2100 g). One of the studies also showed that the chances of survival in women with breast cancer decrease due to excessive body mass – women with the highest BMI had a 2.5 times higher risk of death for 5 years after diagnosis compared with women with the lowest BMI, smoking and alcohol are also importantWomen with breast cancer in both breasts with cancer patients found that avoiding alcohol, maintaining good weight, and not smoking reduced the risk of a second breast cancer.Obese women were 50 percent.higher risk of cancer in the other breast, and in those who drank more than 7 drinks a week, it increased by as much as 90 percent.

Here are the recommendations of WCRF and AICR regarding cancer prevention
Maintain normal body mass (BMI 18.5-24.9).
Exercise at least 30 minutes each day.
Avoid sweet drinks.
Limit food with high energy density (high in calories in a small volume).
Eat more different vegetables, fruits, whole grains and legumes.
Limit eating red meat (including beef, pork, lamb) and avoid meat products (cured meats).
Limit alcohol consumption to 2 drinks for men and 1 drink for women per day (drink is 330 ml of beer, 125 ml of wine or 25 ml of vodka or whiskey).
Limit salt foods and salt-preserved products.
Do not take supplements to protect yourself against cancer.
Do not smoke or chew tobacco
