Superfoods for Cancer Prevention

Must-Eat " Superfoods for cancer prevention”

Super food

1. Cruciferous Vegetables


Broccoli, cauliflower, cabbage, kale, bok choy, etc. Rich in sulforaphane and indoles, which help block the formation of carcinogens. They offer protection against lung, stomach, and colorectal cancers. Recommended for daily consumption.

2. Dark-Colored Vegetables


Spinach, lettuce, purple cabbage, carrots, pumpkin, etc. High in beta-carotene, lutein, and lycopene, with powerful antioxidant properties that protect cells from damage and lower the risk of breast and prostate cancers.

3. Whole Grains & Mixed Beans


Brown rice, oats, corn, quinoa, red beans, mung beans, etc. Loaded with dietary fiber to promote intestinal motility, reduce the contact time of carcinogens in the gut, and effectively prevent colorectal cancer. Use as a substitute for refined white rice and flour.

4. Mushrooms


Shiitake, wood ear mushrooms, enoki mushrooms, king oyster mushrooms, lingzhi, etc. Contain polysaccharides that strengthen the immune system and inhibit the growth of cancer cells, making them natural cancer-fighting ingredients.

5. High-Quality Protein


Deep-sea fish (salmon, cod), eggs, soy products, skinless poultry. Rich in high-quality protein and unsaturated fatty acids to repair body cells. A healthier alternative to red meat for lower cancer risk. Choose hormone-free meat and eggs.

6. Fresh Fruits


Blueberries, strawberries, kiwi, oranges, apples, etc. Packed with vitamin C and polyphenols, providing antioxidant and anti-inflammatory benefits to reduce the risk of digestive tract cancers. A daily intake of 200–350 grams is

Green Tea Polyphenols and Broken-wall Ganoderma Lucidum Spores Enhance Defense Mechanisms

1. Reduce cellular mutation: antioxidant and anti-inflammatory


Green tea polyphenols and Ganoderma polysaccharides work synergistically to reduce DNA damage and minimize cancer initiation at the source.

2. Strengthen immune surveillance: eliminate abnormal cells


Ganoderma lucidum enhances immune cell activity, enabling early detection and removal of mutated cells to prevent progression

3. Inhibit angiogenesis: cut off nutrient supply


Green tea effectively blocks the formation of new blood vessels in tumors, depriving tiny cancer lesions of nutrients and suppressing their growth.

Ganoderma lucidum combined with green tea inhibits tumor growth

(Source: Zhang, et al., FASEB J 2008, 22:1136.2)

• Placebo control group: tumor weight ≈ 2.4 g

• Ganoderma lucidum 100 mg/kg group: tumor weight reduced by 30.2% (p=0.170)

• Ganoderma lucidum 400 mg/kg + green tea 400 mg/kg combined group: tumor weight reduced by 45.2% (p=0.024)

Tegreen (Green Tea Extract): Targeting abnormal cells directly

Core components

Contains >98% tea polyphenols, with EGCG (epigallocatechin gallate) as the main active ingredient, exhibiting strong biological activity.

Mechanisms of action

1. Selectively induce apoptosis: precisely targets cancer cells (e.g., BT-20, HeLa) with minimal effects on normal cells (e.g., MCF-10A).

2. Inhibit angiogenesis: block the tumor nutrient supply chain, effectively suppressing tumor growth and metastasis.

3. Antioxidant and anti-inflammatory: scavenge free radicals, reduce cellular damage, and lower the risk of gene mutation.

Tegreen promotes cancer cell death (apoptosis)

Experimental comparison clearly demonstrates:

• On normal cells (MCF-10A): almost no effect, safe and protective

• On cancer cells (BT-20, HeLa): after adding green tea extract, the number of malignant cells is greatly reduced, and natural apoptosis is triggered.

Core advantages

• ✅ Precisely targets abnormal cells

• ✅ Does not harm healthy cells

• ✅ Inhibits proliferation and helps reduce lesions

Provides scientifically supported cellular protection for gynecological conditions such as uterine fibroids and nodules.
