Medical research has revealed many types of cancers and their possible causes vary, and although medicine has not yet come up with all the answers, it has shown a number of factors that can contribute to the development of cancer.
Genetic composition and family history play a role, but external factors over which you may have some control, such as your lifestyle habits, have a greater influence.
Research published in the Journal of Environmental Medical and Agricultural Research showed that 80-90% of malignant tumors are related to external factors and diet is one of the most important factors to consider.
And the medical journal (Healthline) published a list of foods and beverages that could increase the risk of cancer, and relied on scientific evidence to link these foods to cancer risk.
Some foods may increase the risk of type 2 diabetes and obesity associated with certain types of cancer, and other foods contain carcinogens, which are harmful substances.
The magazine noted that exposure to carcinogens does not always cause cancer, as it depends on your genetic factors as well as the level and duration of exposure to the carcinogen.
1. Processed meat
Processed meat is any type of meat that is preserved by smoking, salting, curing, or canning, and most of it is red meat.
The list includes hot dogs, steaks, sausages and dried meats, and the methods used to make processed meats can be carcinogenic, according to an article published by the US National Library of Medicine.
(Healthline) explained that treating meat with nitrite can lead to the formation of carcinogens called (N-nitroso compounds), and smoking can also lead to carcinogenic polycyclic aromatic hydrocarbons (PAHs), according to a research review published by Medical Library in 2019.
The medical journal cited the same source, that processed meat is a major risk factor for colorectal cancer, and has also been linked to stomach cancer, and the researchers also concluded that high consumption of processed meat is associated with a risk in increase in breast cancer. .
2. Fried foods
The medical journal said that when starchy foods are cooked at high temperatures, a compound called acrylamide is formed and this can occur during frying, baking and baking.
She added that starchy foods are particularly rich in acrylamides, including chips and chips, indicating that acrylamide is carcinogenic, according to studies conducted by the International Agency for Research on Cancer (IARC).
And a study conducted by the Research Center (MDPI) in 2020, stated that acrylamide destroys DNA and leads to programmed cell death.
Eating more fried foods increases the risk of type 2 diabetes and obesity, and these conditions can promote oxidative stress and inflammation, which increases the risk of cancer.
3. Overcooked foods
Excessive cooking of foods, especially meat, can produce carcinogens, according to a study published in 2020, as high heat leads to the production of polycyclic aromatic hydrocarbons and heterocyclic amines (HCA), and these substances increase the risk of cancer by changing nuclear acid. your cell cells.
And the U.S. Food and Drug Administration has talked about grilling and roasting, and the warning also includes overcooking starchy foods, such as potatoes.
To reduce the risk of cancer from high heat cooking, the agency recommends using healthy cooking methods like pressure cooking or low temperature baking and slow cooking in a pot.
The medical journal Healthline said there is some evidence that dairy products may increase the risk of prostate cancer, and that includes milk, cheese and yogurt, according to a 2014 research review by the Oxford Academy.
Eating dairy products increases levels of insulin-like growth factor-1 (IGF-1), which is associated with an increased risk of prostate cancer, and IGF-1 may increase the proliferation or production of stem cells. prostate cancer.
5. Refined sugar and carbohydrates
Sugary foods and refined carbohydrates can indirectly increase the risk of cancer. These include sugary sugary drinks, baked goods, white pasta, white bread, white rice and sugary cereals.
The magazine suggested that a high consumption of foods with starch and sugar could increase the risk of type 2 diabetes and obesity, according to a study conducted in 2020.
But it is certain that these foods promote inflammation and oxidative stress, which may increase the risk of certain types of cancer, according to a 2019 research review.
Type 2 diabetes increases the risk of ovarian, breast and endometrial cancer, and a high intake of sugar and refined carbohydrates can also cause increased blood glucose levels, according to a 2017 study.
To reduce the health effects of refined carbohydrates, try replacing these foods with healthy alternatives like whole grain breads, whole grain pasta, brown rice and oats.
When you consume alcohol, your liver breaks it down into acetaldehyde, a carcinogenic ingredient, according to a 2017 research review.
Acetaldehyde promotes DNA damage and oxidative stress and interferes with your immune function, making it difficult for your body to target cancer cells.
In women, alcohol increases estrogen levels in the body, according to a 2015 study, and this is associated with an increased risk of estrogen receptor-positive breast cancer.
A research review published by the American Library of Health reports that some foods contain beneficial compounds that can help reduce the risk of cancer.
Foods include fruits and vegetables rich in antioxidants, which can help protect the body’s cells from oxidative stress and DNA damage.
A study published in 2015 said nuts can help reduce inflammation and cancer risk, and recommended eating fiber-rich beans and beans, as fiber reduces the risk of colorectal cancer.
Another study, published by the American Library in 2020, showed that whole grains contribute to a lower risk of cancer, such as quinoa and brown rice, which are rich in fiber and antioxidants.
Fish provides healthy fats called omega-3 fatty acids, which reduce the risk of some cancers by reducing inflammation, according to a 2014 study.
