Berries are natural cancer fighters due to their ability to boost the immune system and provide valuable antioxidants. Antioxidants are found in vitamins, minerals and other nutrients. They protect cells in the body from damage from free radicals, or circulating molecules that lead to chronic diseases and cancer. The National Cancer Institute suggests that the best defense against this type of damage is to get an adequate supply of antioxidants through foods containing high levels of beta carotene, lycopene, vitamins A, C and E. Consult a licensed health professional before attempting to self-medicate or otherwise treat any condition on your own.
Black Raspberries
Black raspberries are currently being investigated for their role in reducing esophageal and colon cancer tumor growth. Gary Stoner, researcher at the Comprehensive Cancer Center at Ohio State University, suggests that black raspberries have many nutritional benefits to include phytochemicals that are believed to stave off cancer development. While an overabundance of berries can promote cancer growth, 1 to 2 cups of fresh berries per day may prove to be cancer-fighting.
Blueberries
Blueberries are considered an antioxidant powerhouse. These little berries fight oxidative stress that plays an integral part in the development of colon cancer. According to the Colorectal Cancer Coalition, blueberries eaten with yogurt can help the normal cells defend against oxidative stress damage and provide a healthy balance of probiotics to keep the intestinal tract moving properly. Additionally, the combined influence of probiotics with antioxidant activity may also influence the lining of the colon keeping cancerous polyps at bay. Studies continue in the understanding of how blueberries can fight colon and other cancers.
Strawberries
Strawberries, especially grown in the wild, have shown to exhibit high levels of vitamin C. Researchers at the USDA Agricultural Research Service conducted a study in 2007 to determine the difference in antioxidant and anticancer properties between commercially grown and organically grown wild strawberries. They discovered that the organically grown wild strawberries often exhibited higher levels of antioxidants with the potential to reduce cancer risks in humans. While the research efforts continue, eating either commercially grown or organic and wild strawberries can provide a powerful dose of vitamin C that improves immune system function.
Cranberries
For centuries, the cranberry has been regarded as a panacea for numerous ailments from wound care to urinary tract disorders, gastrointestinal upset, diabetes and liver disease. In addition to the cranberry being investigated for its role in treating Helicobacter pylori infections and ulcers, the National Center for Complementary and Alternative Medicine also suggests that they have shown antioxidant and anticancer activity. Cranberry in excessive amounts can lead to stomach ache and diarrhea. There may also be contraindications between cranberry products and heart medications, aspirin and for those receiving treatment for liver failure.
