The Top 5 Foods That Can Prevent Cancer

Current medical research has shown that there are a range of foods that can promote the growth of cancer cells and tumors in the body. In fact, around 30 to 40% of cancers can be directly linked to diet. For the most part, you may want to be wary of food ingredients such as the additives or chemicals which are added in order to improve flavor or increase product shelf life. Some of these ingredients have been labeled as carcinogens, or cancer promoters, and they should definitely be eliminated from your diet. In general, there is more known about what not to eat, since there has been a lot of research put into this area.

However, were you aware that there are a number of foods that can help to effectively prevent cancer growth or development? That’s right, fortunately there are foods that we can eat which contain cancer-fighting properties, and a healthy diet built around these foods can also help combat heart disease and diabetes. Recently, the World Cancer Research Fund and the American Institute for Cancer Research asked for a comprehensive review to be done on over a thousand different diet, physical activity, and weight studies. The results of this review showed that there were benefits from eating a diet with plenty of plant based foods. These cancer fighting foods tend to be low in fat and calories, and in return they are filled with phytochemicals and antioxidants which work to reduce a person’s risk of cancer.

What Makes These Foods So Great?

The reason that these foods are so good for you can be summed up in one word, antioxidants. There are a variety of chemicals from plants which are called phytochemicals, and technically antioxidants are phytochemicals. Basically these are vitamins and nutrients which can protect our cells from harmful compounds in foods and in the environment, as well as protect against cell damage and mutation. People can eat meals that are rich in fruits and vegetables and effectively lower their risk of cancer. Actually, a diet which can be effective at lowering your risk of cancer is not much different from the traditional healthy diets we have long known about. So in fact, our parents had an extremely good reason for making sure we ate those fruits and vegetables when we were kids!

5 Foods Which Can Lower Your Risk of Cancer


It turns out that this food has more special properties than just being able to scare off the undead and make our breath smelly. Garlic has actually been renowned for its cancer fighting properties for some time now. A recent study has shown a correlation between more garlic in the diet and a lower level of nitrates in the urine. Other studies have shown that garlic contains compounds which especially help protect against skin, lung, and colon cancer.

Cruciferous Vegetables

These vegetables contain strong antioxidants which can help to lower a person’s risk of cancer. These include Brussels sprouts, broccoli, cabbage, cauliflower, watercress, and even mustard greens. All of these veggies are rich in antioxidant phytochemicals and fiber, and you can eat them till your heart’s content. Broccoli actually contains an organosulfur compound called sulforaphane, which targets cancer stem cells. Sulforaphane can help to reduce the risk of breast, stomach, and skin cancer. Eating broccoli raw will retain the highest levels of these sulforaphanes.


Tomatoes have been found to be particularly rich in the compound lycopene. Lycopene is most easily absorbed from cooked tomatoes, and tomato products such as ketchup, spaghetti sauce, and tomato paste are very concentrated sources of the plant chemical. Lycopene can effectively help prevent prostate, breast, cervical, and ovarian cancer.


Berries are abundant in plant chemicals called anthocyanins, which are responsible for giving berries their amazing color. These anthocyanins are also quite potent antioxidants which are effective at protecting against a wide variety of cancers. Blueberries in particular happen to be very rich in these cancer fighting compounds.

Tea (Green and Black)

Both green and black tea happen to be natural sources of particularly potent antioxidants called catechins, which can work to strongly oppose cancer growth by binding itself to a protein that is found on tumor cells. Green tea actually retains more of the antioxidants since it isn’t processed as much as black tea. These teas can be helpful in reducing your risk of skin, liver, and stomach cancer.
