Beans are high in fiber, which some studies have found may help protect against colorectal cancer 7 , 8 , 9. One study followed 1, people with a history of colorectal tumors, and found that those who consumed more cooked, dried beans tended to have a decreased risk of tumor recurrence According to these results, eating a few servings of beans each week may increase your fiber intake and help lower the risk of developing cancer.
However, the current research is limited to animal studies and studies that show association but not causation. More studies are needed to examine this in humans, specifically. Summary Beans are high in fiber, which may be protective against colorectal cancer.
Human and animal studies have found that a higher intake of beans could reduce the risk of colorectal tumors and colon cancer.
Berries are high in anthocyanins, plant pigments that have antioxidant properties and may be associated with a reduced risk of cancer.
Another small study gave freeze-dried black raspberries to patients with oral cancer and showed that it decreased levels of certain markers associated with cancer progression Similarly, another animal study showed that giving rats a berry extract was found to inhibit several biomarkers of cancer Based on these findings, including a serving or two of berries in your diet each day may help inhibit the development of cancer.
Keep in mind that these are animal and observational studies looking at the effects of a concentrated dose of berry extract, and more human research is needed. Summary Some test-tube and animal studies have found that the compounds in berries may decrease the growth and spread of certain types of cancer.
Cinnamon is well-known for its health benefits, including its ability to reduce blood sugar and ease inflammation 16 , In addition, some test-tube and animal studies have found that cinnamon may help block the spread of cancer cells.
A test-tube study found that cinnamon extract was able to decrease the spread of cancer cells and induce their death Another test-tube study showed that cinnamon essential oil suppressed the growth of head and neck cancer cells, and also significantly reduced tumor size An animal study also showed that cinnamon extract induced cell death in tumor cells, and also decreased how much tumors grew and spread However, more studies are needed to understand how cinnamon may affect cancer development in humans.
Summary Test-tube and animal studies have found that cinnamon extract may have anticancer properties and may help decrease the growth and spread of tumors. More research in humans is needed. Research has found that eating nuts may be linked to a lower risk of certain types of cancer.
For instance, a study looked at the diets of 19, people and found that eating a greater amount of nuts was associated with a decreased risk of dying from cancer Another study followed 30, participants for up to 30 years and found that eating nuts regularly was associated with a decreased risk of colorectal, pancreatic and endometrial cancers For example, Brazil nuts are high in selenium, which may help protect against lung cancer in those with a low selenium status These results suggest that adding a serving of nuts to your diet each day may reduce your risk of developing cancer in the future.
Still, more studies in humans are needed to determine whether nuts are responsible for this association, or whether other factors are involved. Summary Some studies have found that an increased intake of nuts may decrease the risk of cancer.
Research shows that some specific types like Brazil nuts and walnuts may also be linked to a lower risk of cancer. Several studies have even found that a higher intake of olive oil may help protect against cancer. One massive review made up of 19 studies showed that people who consumed the greatest amount of olive oil had a lower risk of developing breast cancer and cancer of the digestive system than those with the lowest intake Another study looked at the cancer rates in 28 countries around the world and found that areas with a higher intake of olive oil had decreased rates of colorectal cancer Swapping out other oils in your diet for olive oil is a simple way to take advantage of its health benefits.
You can drizzle it over salads and cooked vegetables, or try using it in your marinades for meat, fish or poultry. Though these studies show that there may be an association between olive oil intake and cancer, there are likely other factors involved as well.
More studies are needed to look at the direct effects of olive oil on cancer in people. Summary Several studies have shown that a higher intake of olive oil may be associated with a reduced risk of certain types of cancer.
Turmeric is a spice well-known for its health-promoting properties. Curcumin, its active ingredient, is a chemical with anti-inflammatory, antioxidant and even anticancer effects. One study looked at the effects of curcumin on 44 patients with lesions in the colon that could have become cancerous.
In a test-tube study, curcumin was also found to decrease the spread of colon cancer cells by targeting a specific enzyme related to cancer growth Another test-tube study showed that curcumin helped kill off head and neck cancer cells Curcumin has also been shown to be effective in slowing the growth of lung, breast and prostate cancer cells in other test-tube studies 30 , 31 , Use it as a ground spice to add flavor to foods, and pair it with black pepper to help boost its absorption.
Summary Turmeric contains curcumin, a chemical that has been shown to reduce the growth of many types of cancer and lesions in test-tube and human studies. Eating citrus fruits such as lemons, limes, grapefruits and oranges has been associated with a lower risk of cancer in some studies.
One large study found that participants who ate a higher amount of citrus fruits had a lower risk of developing cancers of the digestive and upper respiratory tracts A review looking at nine studies also found that a greater intake of citrus fruits was linked to a reduced risk of pancreatic cancer These studies suggest that including a few servings of citrus fruits in your diet each week may lower your risk of developing certain types of cancer.
More studies are needed on how citrus fruits specifically affect cancer development. Summary Studies have found that a higher intake of citrus fruits could decrease the risk of certain types of cancers, including pancreatic and stomach cancers, along with cancers of the digestive and upper respiratory tracts.
Some research has shown that it may even help decrease cancer growth and help kill off cancer cells. In one study, 32 women with breast cancer received either a flaxseed muffin daily or a placebo for over a month. At the end of the study, the flaxseed group had decreased levels of specific markers that measure tumor growth, as well as an increase in cancer cell death In another study, men with prostate cancer were treated with flaxseed, which was found to reduce the growth and spread of cancer cells Flaxseed is high in fiber, which other studies have found to be protective against colorectal cancer 7 , 8 , 9.
Try adding one tablespoon 10 grams of ground flaxseed into your diet each day by mixing it into smoothies, sprinkling it over cereal and yogurt, or adding it to your favorite baked goods. Summary Some studies have found that flaxseed may reduce cancer growth in breast and prostate cancers.
It is also high in fiber, which may decrease the risk of colorectal cancer. Lycopene is a compound found in tomatoes that is responsible for its vibrant red color as well as its anticancer properties.
Several studies have found that an increased intake of lycopene and tomatoes could lead to a reduced risk of prostate cancer. A review of 17 studies also found that a higher intake of raw tomatoes, cooked tomatoes and lycopene were all associated with a reduced risk of prostate cancer Another study of 47, people found that a greater intake of tomato sauce, in particular, was linked to a lower risk of developing prostate cancer To help increase your intake, include a serving or two of tomatoes in your diet each day by adding them to sandwiches, salads, sauces or pasta dishes.
Summary Some studies have found that a higher intake of tomatoes and lycopene could reduce the risk of prostate cancer. However, more studies are needed. The active component in garlic is allicin, a compound that has been shown to kill off cancer cells in multiple test-tube studies 40 , 41 , Several studies have found an association between garlic intake and a lower risk of certain types of cancer.
One study of , participants found that those who ate lots of Allium vegetables, such as garlic, onions, leeks and shallots, had a lower risk of stomach cancer than those who rarely consumed them A study of men showed that a higher intake of garlic was associated with a reduced risk of prostate cancer Another study found that participants who ate lots of garlic, as well as fruit, deep yellow vegetables, dark green vegetables and onions, were less likely to develop colorectal tumors.
However, this study did not isolate the effects of garlic Based on these findings, including 2—5 grams approximately one clove of fresh garlic into your diet per day can help you take advantage of its health-promoting properties.
However, despite the promising results showing an association between garlic and a reduced risk of cancer, more studies are needed to examine whether other factors play a role. Summary Garlic contains allicin, a compound that has been shown to kill cancer cells in test-tube studies.
Studies have found that eating more garlic could lead to decreased risks of stomach, prostate and colorectal cancers. Some research suggests that including a few servings of fish in your diet each week may reduce your risk of cancer.
One large study showed that a higher intake of fish was associated with a lower risk of digestive tract cancer Another study that followed , adults found that eating more fish decreased the risk of developing colorectal cancer, while red and processed meats actually increased the risk This Harvard Healthy Eating Plate is a simple visual that reflects a large body of scientific research on what healthful, plant-based eating looks like.
These recommendations are very consistent with what is currently known about how to eat for cancer prevention and survivorship. The overall goal should be to strike a healthy balance of foods at each meal by planning your plate into these sections:.
Below are tips on how to plan for each part of your plate for optimal nutrition. These compounds offer protection by neutralizing cell-damaging oxidation and inflammation; boosting your immune response; inhibiting potentially cancerous cells from gaining their own blood supply angiogenesis ; encouraging apoptosis cancer cell death ; and assisting your body with natural detoxification.
As the types of phytonutrients in a plant are often tied to the pigments that give them color, if you vary the colors of your fruits and vegetables you will naturally vary your phytonutrient intake. Aim for servings of fruits and vegetables per day.
Whole grains retain all their nutrient-rich elements, including the bran, germ and endosperm, and are important sources of fiber, phytonutrients, vitamins and minerals. Whole grains are also an excellent source of dietary carbohydrates, which are the primary source of energy for the body.
This ¼ of the plate can also include starchy vegetables, like sweet potatoes, winter squash, peas and legumes, which are also nutrient-rich sources of carbohydrate.

However, even for cancers with effective ciet options, prevention has Herbal stress relief greatest potential Anti-cwncer reduce the burden of cancer in the general population. Because each person is exposed to unique environmental and lifestyle factors, cancer risk can vary. Although some factors cannot be controlled such as inherited genetic mutationsthere is a range of modifiable environmental and lifestyle factors that can help reduce the risk of developing cancer. These recommendations were based on the continuous update project of evidence in cancer research, which summarizes current evidence with relevant papers from randomized controlled trials and cohort studies. This may not only help reduce the risk of cancer but may also contribute to the prevention of obesity and other chronic diseases such as type 2 diabetes and cardiovascular disease. Significant increasing weight in adult life is a convincing cause of postmenopausal breast cancer and endometrial cancer.
