What is Breast Cancer?
According to the Mayo Clinic, breast cancer is a growth that forms when a breast cancer cell divides out of control.
And since early breast cancer diagnosis is key in women, cancer screening is everything.
Once you’re diagnosed, you’re also typically tested to see if your estrogen receptors are involved.
And you may be told you have estrogen receptor positive breast cancer, Her2 positive or negative breast cancer.
Although this drives your treatment, we will stick to breast cancer as an umbrella term in this article.
Nutrition and Breast Cancer
Studies show that eating a healthy diet can help lower breast cancer risks.
And lower risk is the key to a healthy life.
Thus, recent cancer research has looked at the largely plant based Mediterranean diet.
It’s packed with:
- Healthy Proteins
- Essential Fatty Acids
- Plant Compounds
- Vitamins & Minerals
In fact, a study published in 2021 showed that it can prevent chronic diseases such as heart disease and protect against cancer.
And clinical trials show it can lower inflammation and keep your immune system strong.
Our 17 foods that prevent breast cancer are all examples of the Mediterranean diet.
And they’re all powerhouses that help protect your body so you don’t develop breast cancer.
17 Foods that Prevent Breast Cancer
Garlic is an allium vegetable with amazing health benefits.
It’s full of powerful organo-sulfides such as alliin, di and trisulfides, and ajoenes.
And strong phenolic antioxidants such as quercetin.
Moreover, research has shown that it fights inflammation, infection, heart disease, diabetes, and breast cancer.
To eat alliums mix them raw in dip, pesto, and salsa, or gently heat in stir-fries and casseroles.
And although not a relative, sweet potato is another powerhouse food worth mentioning.
They’re all high in a group of strong antioxidants called carotenoids that fight inflammation, heart disease, and cancer.
In fact, a recent study found that carotenoids in pumpkin led to lower breast cancer risk in high-risk individuals.
Fill your favorite pumpkin with rice, mushrooms, and lentils, and bake in the oven, or add to smoothies.
3. Purple Cauliflower
Purple cauliflower is rich in anthocyanin which gives it its lovely hue.
Two of those are sulforaphane and indole-3-carbinole.
And they help fight inflammation, heart disease, and many forms of cancer, including breast cancer.
In food, they are great gently steamed, or added to stir-fries and casseroles.
4. Swiss Chard
Swiss chard, arugula, celery, lettuce, and spinach are all leafy green vegetables.
And they’re high in the antioxidants beta-carotene, lutein, and zeaxanthin, which can lower breast cancer risk.
Green leafy vegetables are great in salads, but can also be stir-fried or added to smoothies.
5. Blood Oranges
Blood oranges along with lemons, grapefruit, mandarins, and regular oranges are citrus fruits.
But blood oranges have more anthocyanin antioxidants that give them their red color.
Citrus fruits are also rich in the flavonoids naringin and hesperidin.
And they support the immune system, fight inflammation, and prevent breast cancer.
Blood oranges can be eaten fresh, added to salads and marinades, or mixed in smoothies or juices.
Blueberries especially wild blueberries and açai are among the foods richest in anthocyanins.
And anthocyanins are strong antioxidants that give blueberries their blue color.
But blueberries also have good amounts of the flavonoids kaempferol and quercetin.
These antioxidants work wonders for the digestive system, brain, heart and blood vessels, and skin.
Moreover, they’re anti-inflammatory, anti-diabetic, and protect against breast cancer.
Pomegranate is a colorful round fruit filled with juicy edible seeds.
Other colorful fruits include apples, mango, peaches, pears, and grapes.
But pomegranate is especially rich in antioxidants, particularly vitamin C, anthocyanins, punicalagin, and ellagic acid.
To eat a pomegranate, cut it in half, scoop out the seeds, and use them in salads, marinades, and hummus.
8. Low-Fat Kefir
Fermented low fat dairy products such as yogurt and kefir play an important part in a healthy diet.
Kefir is a cultured milk product with more beneficial bacteria than yogurt.
Its main antioxidants include vitamin A, carotenoids, sulfur-containing amino acids, and whey protein.
And therefore, it’s beneficial for the gut, anti-inflammatory, and may fight breast cancer.
9. Chili Pepper
Herbs and spices are generally regarded as anti-inflammatory cancer fighters.
And chili peppers, in particular, are loaded with antioxidants and plant compounds.
One of those is capsaicin which could play a role in fighting breast cancer.
Add dried basil, mint, parsley, rosemary, and a pinch of chili or cayenne pepper to foods or mix fresh herbs in salads.
Turmeric just like ginger is a flowering plant whose rhizome is used medicinally.
Turmeric is high in curcumin which has antioxidant, anti-inflammatory, and cancer-fighting properties.
Add turmeric and ginger to smoothies, teas, and your favorite stir fry or casserole.
PRO TIP!Curcumin is poorly absorbed, but by adding black pepper you can drastically increase it.
Soybeans and soy foods such as soy milk, tofu, miso, and tempeh are high in the antioxidants genistein and daidzein.
And although they’ve caused a stir in the past, current data tells a different story.
In fact, eating soy reduces the risk of breast cancer in pre- and postmenopausal women.
And consequently, breast cancer survivors shouldn’t be afraid to eat soy foods in moderation.
12. Maitake Mushrooms
Maitake mushrooms or hen-of-the-woods are edible fungi with an earthy sweetish flavor.
Other mushrooms include white button, portobello, reishi, shiitake, and turkey tail.
They’re rich in a polysaccharide called beta-glucan.
And beta-glucan is anti-inflammatory, protects heart health, and may prevent breast cancer.
To eat mushrooms, pan-fry with canola oil, chives, and garlic or put in casseroles.
Although almonds, hazelnuts, and flax- and chia seeds are amazingly healthy, walnuts are the star of all.
And they’re high in melatonin, plant sterols, phenolic acids, flavonoids, and tannins.
Furthermore, they have impressive heart health, anti-inflammatory, and anti-cancer properties.
Thus, adding about 1-2 handfuls of walnuts per day in salads, pesto, or smoothies may help prevent breast cancer
14. Extra Virgin Olive Oil
Extra virgin olive oil or EVOO is the healthiest, most flavorful, and least processed olive oil of all varieties.
And it has the most polyphenols such as oleuropein and hydroxytyrosol.
They’re powerhouse antioxidants that fight free radical damage that otherwise can result in cancer.
EVOO also stimulates the immune system and prevents heart disease, and is anti-cancer, anti-inflammatory, and antiseptic.
Thus, EVOO is consistent with a lower risk of breast cancer.
Barramundi or Asian Sea Bass is a mildly sweet and buttery-flavored white fish.
It’s sustainably farmed and largely toxin-free.
And compared to salmon, it packs about a quarter of the omega-3 fatty acids in half the calories.
Omega-3s reduce inflammation and heart disease, protect the brain, and prevent breast cancer.
Thus, it can be a leaner alternative to salmon even though it’s not technically a fatty fish.
16. Purple Rice
Purple rice, barley, oats, and quinoa are whole grains, meaning they consist of all layers of a kernel.
Because of that, they’re packed with fiber and nutrients making them real nutritional powerhouses.
Purple rice perhaps the most amazing whole grain gets its purple color from the powerful antioxidant anthocyanin.
Furthermore, it boosts the healthful compounds quercetin, carotenes, tocopherols, plant sterols, and stanols.
And that strong antioxidant power helps lower the risk of heart disease, obesity, diabetes, and breast cancer.
17. Green tea
Green tea is made by steeping the leaves of the Camellia Sinensis plant.
The main bioactive component in green tea is the powerful antioxidant epigallocatechin gallate or EGCG.
EGCG is a polyphenol that can protect the brain and liver, reduce inflammation, and prevent breast cancer.
