What you eat can dramatically affect many aspects of your health, including the risk of developing cancer, chronic diseases, such as heart disease and diabetes. Many studies have shown that cancer development, in particular, is closely related to the food you eat. It is no secret to anyone that many foods contain beneficial compounds that could help slow the development of cancer. There are also several studies that show that a higher intake of certain foods could be associated with a lower risk of suffering from this condition.
This article will deepen and analyze 13 foods that can reduce the development of cancer according to studies.
Can broccoli prevent cancer development?
Broccoli contains sulforaphane, a plant compound found in cruciferous vegetables and that can have potent anti-cancer properties. Including broccoli weekly as a companion in some meals can give you some benefits to fight cancers. A test tube study showed that sulforaphane reduced the size and amount of breast cancer cells by up to 75%. Similarly, an animal study found that treating mice with sulforaphane helped eliminate prostate cancer cells and reduced tumor volume by more than 50%. Some studies have also found that increased consumption of cruciferous vegetables, such as broccoli, may be related to a lower risk of developing colorectal cancers. However, it should be borne in mind that the available research has not directly analyzed the effects of broccoli on the development of cancer in humans. Rather, it has been limited to laboratory, animal and observational studies, which investigated the effects of cruciferous vegetables or the effects of a specific compound on broccoli, therefore, more studies are needed.
Summary: Broccoli contains sulforaphane, a compound that has been shown in studies in test tubes and in animals that eliminates cancereous cells and reduces tumor size. An increased intake of cruciferous vegetables may also be associated with a lower risk of colorectal cancer.
Can carrots prevent the development of cancer?
Several studies have found that including carrots in the daily diet is related to a lower risk of certain types of cancer. For example, an investigation analyzed the results of five studies and concluded that eating carrots can reduce the risk of stomach cancer by up to 26%.
“Another study found that a higher intake of carrots was associated with an 18% lower chance of developing prostate cancer”.
One study analyzed the diets of 1,266 participants with and without lung cancer. He found that current smokers who did not eat carrots were three times more likely to develop lung cancers, compared to participants who ate carrots more than once a week. Try incorporating carrots into your diet as a healthy snack or a delicious companion a few times a week, and thus potentially reduce the risk of cancer. Even so, remember that these studies show a relationship between carrot consumption and cancerous cells, but do not take into account other factors that can play an important role.
Summary: Some studies have found a relationship between carrot consumption and decreased risk of prostate, lung and stomach cancer.
Can beans prevent the development of cancer?
Beans are rich in fiber , which, according to some studies, can help protect against colorectal cancers. In fact, several studies have found that a higher intake of beans can reduce the risk of such a condition. One study followed 1,905 people with a history of colorectal tumors, found that those who consumed more cooked dried beans tended to have a lower risk of tumor recurrence. An animal study also found that feeding mice with black beans or white beans, after inducing colon cancer, blocked the development of cancer cells by up to 75%. Based on these results, eating a few servings of beans each week may increase fiber intake, and in turn, help reduce the risk of developing cancers. However, current research is limited to animal studies and studies showing association, but not causation. More studies are needed to examine this in humans specifically.
Summary: Beans are rich in fiber, which can protect against colorectal cancer. Studies in humans and animals have found that increased intake of beans could reduce the risk of colorectal tumors and colon cancer.
Do berries help prevent the development of cancer?
Berries have a high anthocyanin content, are plant pigments that have antioxidant properties and may be associated with a lower risk of developing cancer. In one study, 25 people with colorectal cancer were treated with cranberry extract for seven days; this reduced the growth of cancer cells by 7%. Another small study administered lyophilized black raspberries (a process in which they are frozen and thawed, preserved under vacuum and at low atmospheric pressure), to patients with oral cancers, and showed that the levels of certain markers associated with cancer development were decreasing. An animal study found that feeding mice with lyophilized black raspberries reduced the formation of esophageal tumors by up to 54% and decreased the number of tumors in general by up to 62%. Similarly, another animal study showed that by giving mice an extract of berries, it was found that they prevented the formation of several cancer biomarkers. Based on these findings, including a portion or two of berries in your diet every day can help inhibit the development of cancers. It is important to keep in mind that these studies have been carried out in animals, and are observational, which only analyze the effects of a concentrated dose of berry extract. More research is required in people.
