Nutrition plays a key role in preventing many diseases, including cancer. Many foods contain compounds with anti-cancer effects that support the immune system and protect cells from harmful changes. If you want to reduce your risk of developing cancer, include these foods in your diet.
1. Fatty fish
Fatty fish are rich in omega-3 fatty acids, which have strong anti-inflammatory effects. Regular consumption of these healthy fats can help reduce cancer risk, especially due to their ability to regulate cellular processes and limit the harmful effects of inflammation.
The best sources of omega-3 fatty acids are:
-
salmon
-
mackerel
-
tuna
-
herring
-
sardines
In addition to omega-3 fatty acids, these fish also contain vitamins A and D, which support the immune system and help protect cells from damage.
2. Mushrooms
Mushrooms have long been part of traditional Chinese medicine and are valued for their positive effects on the immune system. They contain beta-glucans, which enhance the activity of white blood cells and increase the body’s defenses.
Best mushrooms with anti-cancer effects:
-
oyster mushroom
-
shiitake
-
maitake
-
portobello
-
agaricus blazei
-
chaga (Inonotus obliquus)
Studies have shown that consuming these mushrooms can reduce the side effects of chemotherapy and radiotherapy and even help shrink tumors.
3. Purple-colored foods
Foods that are naturally purple contain anthocyanins, powerful antioxidants that can help slow the growth of cancer cells and support organ health.
Some of the most effective purple foods include:
-
blueberries
-
beetroot
-
purple grapes
-
plums
-
cherries
-
eggplant
Include these foods in your diet to support immunity and protect cells from oxidative stress.
4. Seeds and nuts
Seeds and nuts contain important minerals and vitamins that can help reduce cancer risk. Selenium in Brazil nuts is a powerful antioxidant that protects cells from damage.
Other key nutrients in seeds and nuts:
-
sunflower seeds (rich in vitamin E)
-
pumpkin seeds (a source of zinc)
-
almonds (contain healthy fats and antioxidants)
Vitamin E supports the immune system and zinc helps the body better absorb vitamin C, thereby increasing overall resistance.
5. Green and black tea
The tea plant contains catechins, which are powerful antioxidants with anti-cancer properties. Regular tea drinking can help reduce the risk of stomach, breast, prostate, colon and lung cancers.
The best types of teas with anti-cancer effects:
-
green tea
-
white tea
-
black tea
-
oolong tea
Drinking 2–3 cups of green tea a day can help protect cells and strengthen the immune system.
6. Red and yellow peppers
Peppers are rich in vitamin C, beta-carotene and other antioxidants that help neutralize free radicals and boost immunity.
Other foods with similar effects:
-
carrots
-
sweet potatoes
-
dried apricots (unsulphured)
These foods not only support cellular health but also help the body fight harmful toxins.
How to include these foods in your diet?
You can start gradually – simply include at least one of the listed foods each day. For example:
-
In the morning enjoy a cup of green tea and a handful of nuts.
-
For lunch add grilled salmon and red pepper.
-
For dinner have a salad with mushrooms and seeds.
-
For dessert enjoy blueberries or cherries.
Small dietary changes can have a big impact on your health. Include these foods in your diet to support the body’s natural defenses.
