13 Foods That Can Prevent Cancer - Based on Studies

What you eat can drastically affect many aspects of your health, including the risk of developing chronic diseases, such as heart disease, diabetes and cancer.

13 Foods That Can Prevent Cancer - Based on Studies


Many studies have shown that the development of cancer, in particular, is closely related to the foods you eat.

It is no secret to anyone that many foods contain beneficial compounds that may help slow the development of cancer.

There are also several studies that show that a higher intake of certain foods may be associated with a lower risk of the condition.

This article will explore and analyze 13 foods that may reduce the development of cancer based on studies.

1. Carrots

Carrots


Can the carrot prevent the development of cancer?


Several studies have found that including carrots in the daily diet is associated with a lower risk of certain cancers.

For example, research 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 looked at the diets of 1,266 participants with and without lung cancer. It found that current smokers who didn't eat carrots today were three times more likely to develop lung cancer, compared to participants who ate carrots more than once a week.

Try adding carrots to your diet as a healthy snack or a delicious side dish a few times a week to potentially reduce your risk of cancer.

Still, remember that these studies show a link between carrot consumption and cancer, but do not take into account other factors that may play a role.

2. Broccoli

Broccoli


Can broccoli prevent the development of cancer?


Broccoli contains sulforaphane, a plant compound found in cruciferous vegetables that can have potent anti-cancer properties.

Including broccoli as an accompaniment in some meals on a weekly basis can give you some cancer-fighting benefits.

A study of test tubes showed that sulforaphane reduced the size and number 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 associated with a lower risk of colorectal cancer.

However, it should be noted that 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, so more studies are needed.

3. Beans
