The development of cancer, in particular, has been shown to be heavily influenced by your diet. There are also several studies showing that a higher intake of certain foods could be associated with a lower risk of the disease.

1. Broccoli
Broccoli contains sulforaphane, a compound that has been shown to cause tumor cell death and reduce tumor size in test-tube and animal studies.

Including broccoli with a few meals per week may come with some cancer-fighting benefits.

2. Carrot
Some studies have found an association between carrot consumption and a decreased risk of prostate, lung and stomach cancer.

Try incorporating carrots into your diet as a healthy snack or delicious side dish just a few times per week to reduce your risk of cancer.

3. Beans
Human and animal studies have found that a higher intake of beans could reduce the risk of colorectal tumors and colon cancer.

Eating a few servings of beans each week not only increase your fiber intake but also help lower the risk of developing cancer.

4. Cinnamon
Test-tube and animal studies have found that cinnamon extract may have anticancer properties and may help decrease the growth and spread of tumors.

Including 2–4 grams of cinnamon in your diet per day may be beneficial in cancer prevention.

5. Nuts
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.

6. Olive
Swapping out other oils in your diet for olive oil is a simple way to take advantage of its health benefits to prevent cancers.

You can drizzle it over salads and cooked vegetables, or try using it in your marinades for meat, fish or poultry.

7. Turmeric
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.

For the best results, aim for at least 1–3 grams of ground turmeric per day. You can use it as a ground spice to add flavor to foods, and pair it with black pepper to help boost its absorption

8. Citrus fruits
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.

You should eat more citrus fruits such as oranges, lemons, grapefruits... to lower risk of cancers.

9. Flaxseed
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.

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.

10. Tomato
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.

You can add two of tomatoes in your diet each day by adding them to sandwiches, salads, sauces or pasta dishes.

11. Garlic
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.

You can include 2–5 grams (approximately one clove) of fresh garlic into your diet per day can help you take advantage of its health-promoting properties.
