There are many myths about the components of the diet that increase the risk of cancer. Some are true and others are not. To find out which ones you should limit or eliminate, know the real culprits according to scientific evidence, and why.
1. Red meat
The high consumption of beef and sausages was associated with a 22% increase in the risk of breast cancer in general. For each additional daily portion, there is a 13% increase in risk, according to a study published in the British Medical Journal. They analyzed more than 88 thousand women between 26 and 45 years old.
Addicted to steaks, it is better to limit consumption a bit. A new study indicates that red meat may increase the risk of developing colon cancer by up to 36%. The research, conducted by the American Institute for Cancer Research, provides strong evidence against this popular food.
2. Sweet snacks
Because of the high amount of refined sugar and fat, sweet snacks like cookies or donuts can cause colorectal cancer. This was determined by a study by the universities of Aberdeen and Edinburgh, in Scotland, which analyzed the diets of 2,000 patients with colorectal cancer and compared them with those of a similar population group.
Better not be tempted
This 2013 study was one of the first to find a link between this type of cancer and the diet high in sugar and fat. And they added another important factor in the incidence of cancer: the high caloric content of certain sweet snacks. Doctors advise replacing them with fruits, vegetables or nuts.
3. The white flours
It is known that excessive consumption of these promotes several diseases, but what little is said is that the bleaching process to which the flour is subjected is based on a chemical called chlorine gas. The Environmental Protection Agency (EPA) indicates that it is a dangerous irritant not safe to inhale and that in large quantities, it can be lethal.
4. Processed meats
We talk about sausages, bacon, salami, hams. Meat processing, by adding preservatives such as salt or sodium nitrite to prevent bacterial growth, may add compounds that could increase the potential to cause cancer, according to the American Cancer Society. They were also declared carcinogenic by the World Health Organization (WHO).
Is there evidence?
Some studies link the consumption of large quantities of processed meats with an increased risk of colorectal cancer. It may be due to nitrites, added to many cold meats, cold cuts and sausages. And many contain alkyl tran, another known carcinogen that is also present in cigarettes.
5. Refined sugar
It increases insulin levels and several studies certify that this is a cancer-stimulating food. But be careful: substitutes such as artificial sweeteners are made with aspartame and this is also harmful. To sweeten, honey and molasses are better, but always in small quantities.
The Nobel Prize in Medicine, Otto Warburg, discovered in 1931 that tumors and cancers use sugars to feed and grow. To proliferate, cancer cells prefer fructose-rich body nutrients, such as high-fructose corn syrup (HFCS) that is metabolized more quickly and easily.
There is great evidence that feeds based on a high content of foods cured with salt or prepared in vinegar carry an increased risk of stomach cancer, nasopharyngeal cancer, and throat cancer, reports the American Cancer Society.
7. Canned tomatoes
Not only tomatoes but most canned foods are a major concern since the coating includes a product called bisphenol-A or BPA, which causes serious genetic alterations that result in serious diseases, according to the National Academy of Sciences. BPA is an agent suspected of causing cancer.
Who is exposed to the BPA?
This chemical is very present in food and beverage containers; He lives with him. The National Health Review and Nutrition Survey (NHANES III, 2003-2004) report of the Centers for Disease Control and Prevention (CDC) found detectable BPA levels in 93% of the 2,517 urine samples of children and adults.
8. Pesticides in fruits and vegetables
Some substances such as atrazine, third carb, and organophosphates, as well as high nitrogen fertilizers, are very dangerous. According to the Environmental Protection Agency (EPA), pesticides have been linked to several health problems and could be carcinogens or alter the hormonal system.
Although very nutritious and recommended for its value in preventing diseases, apples were the fruits that tested positive for at least 99% of the pesticide residues analyzed. Despite being one of the most valuable fruits, you should be careful in its consumption, for example, discarding the peel.
As much as a sedentary lifestyle, everything that makes you fat increases the risk. The American Cancer Society reports that being overweight or obese is associated with an increased risk of breast, colon, endometrial, esophageal, kidney and pancreas cancer, as well as the gallbladder. And probably liver, prostate, cervix and ovary, and non-Hodgkin lymphoma.
10. Microwave Popcorn
The harmful thing is not popcorn, but the container bag to heat them. The product is perfluorooctanoic acid (PFOA) a toxin that has been shown to cause cancer in laboratory animals. The EPA wants the use of this chemical to be phased out of the products.
