Many people today are confused about diet, especially when it comes to cancer prevention and cancer recovery. The “sugar feeds cancer” concept has caused many to avoid fresh fruits and other critical nutrient-dense foods such as whole grains and other beneficial complex carbohydrates. Whether you want to prevent cancer or support cancer recovery, there are many cancer-fighting whole foods that you should consider including in your daily diet.

The Cancer-Fighting Food Plan

Here are some tips for creating a powerful eating plan.

1. Eat Whole Foods

Eat a diet consisting of whole foods. This is essential for promoting better health and for preventing cancer. Begin to eliminate processed, convenience, and fast foods.

2. Reduce Red Meat

Reduce or eliminate the consumption of red meat. If you eat red meat, limit portions to four ounces and have once a week or less. Choose grass-fed, wild, or organic beef and poultry and pair it with two servings of colorful vegetables.

3. Add Flax to Your Diet

Add 1-2 tablespoons of freshly ground flax seeds to a smoothie, soup, or salad. Flax seeds are high in a substance called “lignans,” which are known for their ability to help prevent viral, bacterial, and fungal infections. Ground flax seeds also provide essential Omega-3 fats and are an excellent source of fiber. Flax lignans are considered cancer-preventive and may inhibit the spread of cancer.1

4. Eat Cruciferous Vegetables

Power up with cruciferous vegetables. Much research has shown the anti-cancer properties of vegetables such as broccoli, cabbage, Brussels sprouts, cauliflower, kale, collards, radishes, and turnips. However, the sprouts of certain crucifers, such as broccoli, contain 10-100 times higher levels of the cancer-fighting substance sulforaphane, which has been shown to inhibit cancer stem cells.2

5. Include Glutathione-Boosting Foods

Add foods that boost glutathione, our body’s premier internal antioxidant. Asparagus is the best source of glutathione, but many other foods increase our body’s ability to produce it naturally. Avocado, cilantro, spinach, garlic, eggs, and un-denatured (cold processed) whey protein (from grass-fed cows or goats) are known to improve glutathione production. Eating two Brazil nuts daily effectively increases selenium, an essential trace mineral for glutathione production and cancer prevention.

6. Eat Some Bitter Greens

Consume bitter greens regularly, both cooked and raw. These include watercress, mustard greens, romaine lettuce, arugula, escarole, chard, and kale, which are good choices. Dandelion greens are one of the best choices since they are the best food for the liver. Dandelion greens promote the flow of bile and have anti-tumor effects. The roots and leaves have traditionally been used to support liver function in cancer patients. Add bitter greens to salads or juice blends.

7. Include Cancer-Fighting Fruits

All fruits have cancer-fighting and healing properties, especially berries3. Choose organic blueberries, blackberries, elderberries, raspberries, cranberries, and strawberries. Berries are nutrient-dense and packed with antioxidants, fiber, and potent phytonutrients that can help improve health and fight cancer. Cranberries can inhibit tumor growth.4 

8. Eat Citrus Fruits

Citrus is also beneficial for optimal health. Grapefruit boosts cancer-fighting liver enzymes and improves detoxification. The citrus peel contains some of the most anti-cancer, liver-protective substances called terpenes. Mince the peel of lemon, lime, grapefruit, oranges, and tangerines, and sprinkle over salads or use in smoothies.

9. Use Bone Stock (Broth)

Bone stock is gaining popularity, although it is a traditional food. Use bone stock to make soups, or add it to rice and steamed vegetables. This healing food is excellent for the immune system, digestive tract, joints, and bones. If you make homemade stock, purchase only organic bones from healthy, humanely raised animals.

Most natural health practitioners agree that sugar is a driver in the development and progression of cancer. But don’t discard cancer-fighting fruits (listed above). Consume these powerful fruits moderately and as part of balanced meals. The same goes for grains, which can feed beneficial gut flora and provide fiber. What is more important is controlling your blood glucose and insulin levels through a balanced diet, herbs, supplements, exercise, and meditation. This is one of a cancer preventive or recovery program’s most crucial components.
