Healthy diet for cancer prevention -
Summary Broccoli contains sulforaphane, a compound that has been shown to cause tumor cell death and reduce tumor size in test-tube and animal studies. A higher intake of cruciferous vegetables may also be associated with a lower risk of colorectal cancer.
Several studies have found that eating more carrots is linked to a decreased risk of certain types of cancer. One study analyzed the diets of 1, participants with and without lung cancer.
It found that current smokers who did not eat carrots were three times as likely to develop lung cancer, compared to those who ate carrots more than once per week 6. Try incorporating carrots into your diet as a healthy snack or delicious side dish just a few times per week to increase your intake and potentially reduce your risk of cancer.
Summary Some studies have found an association between carrot consumption and a decreased risk of prostate, lung and stomach cancer. 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 On the other hand, eating a variety of vegetables, fruit and other high-fibre foods helps reduce your risk of cancer.

The evidence shows that alcoholic drinks of all types have a similar impact on cancer risk. This recommendation therefore covers all types of alcoholic drinks, whether beer, wine, spirits liquorsor any other alcoholic drinks, as well as other alcohol sources.
Eat a diet rich in whole grains, vegetables, fruit, and beans. There is strong evidence that eating whole grains protects against colorectal cancer, and that eating foods containing dietary fiber protects against colorectal cancer, weight gain, overweight, and obesity, which, as described above, increases the risk of many cancers.
Most of the evidence on fast foods is from studies looking at burgers, fried chicken, French fries, and high-calorie drinks containing sugar, such as soda; or unhealthy fats, such as shakes.
Limit red and processed meat. Processed meat has been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavor or improve preservation.
Although these products are often made from red meat i. While both red and processed meat were suggested to increase the risk of a number of other cancersthe evidence was most convincing for colorectal cancer.
Because meat can be a valuable source of nutrients, in particular protein, iron, zinc, and vitamin B12, the recommendation is to limit rather than completely avoid minimally processed red meat.
However, poultry and seafood are generally healthier sources of protein as well as many of these other nutrients. Very little, if any, processed meat should be consumed. Limit sugar-sweetened drinks. As noted above, obesity increases the risk of many cancers.
Avoiding tobacco and excess sun exposure The recommendations also emphasize that not smoking and avoiding other exposure to tobacco and excess sun are also important in reducing cancer risk. Cancer survivorship With improved early detection and availability of more advanced treatment options, people diagnosed with cancer are living much longer.

Dip carrots, celery, cucumbers, jicama, and peppers in hummus. Keep trail mix made with nuts and dried fruit on hand. Dinner: Add fresh or frozen veggies to your favorite pasta sauce or rice dish. Top a baked potato with broccoli, sautéed veggies, or salsa. Fiber, also called roughage or bulk, is found in fruit, vegetables, and whole grains and plays a key role in keeping your digestive system clean and healthy. It helps keep cancer-causing compounds moving through your digestive tract before they can create harm. Eating a diet high in fiber may help prevent colorectal cancer and other common digestive system cancers, including stomach, mouth, and pharynx. Eating a diet high in fat increases your risk for many types of cancer. But healthy types of fat may actually protect against cancer. Avoid trans fat or partially hydrogenated oil found in packaged and fried foods such as cookies, crackers, cakes, muffins, pie crusts, pizza dough, French fries, fried chicken, and hard taco shells. Add more unsaturated fats from fish, olive oil, nuts, and avocados. Omega-3 fatty acids found in salmon, tuna, and flaxseeds can fight inflammation and support brain and heart health. Instead of sugary soft drinks, sweetened cereals, white bread, pasta and processed foods like pizza, opt for unrefined whole grains like whole wheat or multigrain bread, brown rice, barley, quinoa, bran cereal, oatmeal, and non-starchy vegetables. It could lower your risk for colorectal and prostate cancer as well as help you reach a healthy weight. Many different studies have established a link between the risk of cancer and eating processed meat such bacon, sausages, hotdogs, pepperoni, and salami. Eating about 2 oz. This could be due to the nitrate preservatives or other substances used in the processing of the meat, although risk factors for cancer also increase by eating red meat, too. The safest strategy is to limit the amount of processed meat you consume and vary your diet by seeking out other protein sources , such as fish, chicken, eggs, nuts, and soy, rather than relying just on red meat. Choosing healthy food is not the only important factor in preventing cancer. It also matters how you prepare, store, and cook your food. Here are a few tips that will help you get the most benefits from eating all those great cancer-fighting foods, such as fruit and vegetables:. Eat at least some raw fruits and vegetables as they tend to have the highest amounts of vitamins and minerals, although cooking some vegetables can make the vitamins more available for our body to use. When cooking vegetables, steam only until tender. This preserves more of the vitamins. Overcooking vegetables removes many of the vitamins and minerals. If you do boil vegetables, use the cooking water in a soup or another dish to ensure you're getting all the vitamins. Wash all fruits and vegetables. Use a vegetable brush for washing. Washing does not eliminate all pesticide residue, but will reduce it. Flavor food with immune-boosting herbs and spices. Garlic, ginger, and curry powder not only add flavor, but they add a cancer-fighting punch of valuable nutrients. Other good choices include turmeric, basil, rosemary, and coriander. Try using them in soups, salads, and casseroles. Carcinogens are cancer-causing substances found in food. They can form during the cooking or preserving process—mostly in relation to meat—and as foods starts to spoil. Examples of foods that have carcinogens are cured, dried, and preserved meats e. bacon, sausage, beef jerky ; burned or charred meats; smoked foods; and foods that have become moldy. Do not cook oils on high heat. Low-heat cooking or baking less than degrees prevents oils or fats from turning carcinogenic. Instead of deep-frying, pan-frying, and sautéing, opt for healthier methods such as baking, boiling, steaming, or broiling. Go easy on the barbecue. Burning or charring meats creates carcinogenic substances. If you do choose to barbecue, flip frequently to avoid charring, don't overcook the meat, and be sure to cook at the proper temperature not too hot. When fat drips onto the flames, it can also release another chemical linked to cancer, so opt for leaner cuts of meat if you can. Store oils in a cool dark place in airtight containers, as they quickly become rancid when exposed to heat, light, and air. Avoid food that looks or smells moldy, as it likely contains aflatoxin, a strong carcinogen most commonly found on moldy peanuts. Nuts will stay fresh longer if kept in the refrigerator or freezer. Some fibers help prevent fat and cholesterol absorption, helping you lower your cholesterol over time. Stabilized blood sugar levels. Or at risk of becoming diabetic? Fiber can positively influence blood sugar levels by slowing how quickly sugar gets into your blood stream. Bowel management. Have digestive problems? Adding fiber to your diet can help protect your intestinal lining and make bowel movements easier or more frequent. Include lean proteins. Here are some guidelines for consuming red meat: Eat no more than 18 ounces of red meat per week. Each serving should be around three ounces, which is about the size of a regular deck of cards. Avoid burning or charring your meat because it creates compounds in the meat that have been linked to cancer. Use slow, low temperature cooking methods like baking or roasting. If you grill your meat, marinate it and finish off cooking in the oven or microwave. Follow the sugar stoplight. Natural sugars are safe to eat. Any sugar that is naturally occurring in a food gets the green light. That includes sugar in fruit and starchy vegetables, as well as whole or minimally processed carbohydrates like brown rice and whole grain pasta. Sugar in dairy products like milk and cheese is OK, too. Added sugar should be eaten in moderation. Foods with added sugar get the yellow light. That includes the cane sugar in your yogurt, the honey or syrup in your granola bar, as well as the agave you might put in a drink. Added sugar can also appear in foods like bread and pasta sauce. Refined or processed sugar should be limited. Eat red light foods as little as you can because they contain a lot of processed sugar. One candy bar or piece of cake can contain around 30 grams of added sugar. Eating these foods regularly leads to weight gain and other problems. Sodas and sweetened beverages get the red light, too, even if they use artificial sweeteners. Be aware of sugar spikes. Limit alcohol. Tips for moving toward a healthy diet Start slowly — look for progress, not perfection. Here some ideas: Increase the amount of fruits and vegetables you eat. This might be by increasing the percentage of produce on your plate at each meal or the number of servings per day. Eat the rainbow daily or weekly to add more color to your diet. If you aim to eat the rainbow, you will automatically increase the amount and variety of fruits and veggies in your diet. Snack on healthy foods, such as fruits, vegetables, nuts and seeds. Switching up snacks is a simple way to move toward healthy eating. Reduce intake of red and processed meats by choosing fish , seafood or poultry, or going meatless more often. There are many great plant-based protein options such as beans, lentils, peas and tofu. Eat them a few times per week. Choose whole grains or other whole food carbohydrates rather than processed carbohydrates at meals. Try spaghetti squash or veggie noodles instead of pasta. Switch to brown rice or quinoa instead of white rice. Eat salad as your meal. Top it off with nuts, seeds or beans as a protein source. Eat fruit for dessert. Featured Articles.

| 36 foods that can help lower your cancer risk | MD Anderson Cancer Center | There is no miracle food that can prevent or cure cancer, but your overall diet can affect your cancer risk. About 1 in 5 cancer cases can be prevented by eating well, being active and maintaining a healthy body weight. In the past, researchers studied specific food components that they thought protected against cancer, such as antioxidants. But scientists are now taking a broader approach by looking at healthy eating patterns in relation to cancer prevention. Understanding the links between diet and cancer is difficult because we consume thousands of dietary components every day. Eating a balanced diet can help you get to and stay at a healthy body weight, which reduces your risk of cancer. Certain types of food — not certain foods — reduce or increase the risk of cancer. For example, eating processed meat increases your risk of colorectal cancer. On the other hand, eating a variety of vegetables, fruit and other high-fibre foods helps reduce your risk of cancer. 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.
