Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Modified Citrus Pectin
OverviewThis section contains the following key information:Citrus pectin is a complex polysaccharide found in the peel and pulp of citrus fruit and can be modified by treatment with high pH and temperature.Preclinical research suggests that modified citrus pectin (MCP) may have effects on cancer growth and metastasis through multiple potential mechanisms.Very limited clinical research has been done with a couple of citrus pectin-containing products. For prostate cancer patients, the results suggest some potential clinical benefits with relatively minor and infrequent adverse events.General Information and HistoryPectin is a complex polysaccharide contained in the primary cell walls of terrestrial plants. The word ‘pectin' comes from the Greek word for congealed or curdled. Plant pectin is used in food processing as a gelling agent and also in the formulation of oral and topical medicines as a stabilizer and nonbiodegradable matrix to support controlled drug delivery. Citrus

Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Patient Information [NCI] - Questions and Answers About Lycopene
What is lycopene?Lycopene is a carotenoid (a natural pigment made by plants). Lycopene protects plants from stress and helps them use the energy of the sun to make nutrients. Lycopene is found in fruits and vegetables like tomatoes, apricots, guavas, and watermelons. The main source of lycopene in the American diet is tomato-based products. Lycopene is more bioavailable (easier for the body to use) in processed tomato products like tomato paste and tomato puree than in raw tomatoes. Eating carotenoids, including lycopene, along with dietary fat may help the body absorb them. For example, one study showed that more lycopene was absorbed from diced tomatoes cooked with olive oil than diced tomatoes cooked without olive oil.Lycopene in the diet may affect antioxidant activity and communication between cells. Laboratory and animal studies have shown that lycopene may help lower the risk of prostate, skin, breast, lung, and liver cancers. However, clinical trials of whether lycopene lowers

Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Patient Information [NCI] - Questions and Answers About Soy
What is soy?The soybean plant has been grown in Asia for food since ancient times. Soy first arrived in Europe and North America in the 18th century. The soybean can be processed into a wide variety of products including soy milk, miso, tofu, soy flour, and oil. Soy foods contain many phytochemicals that may have health benefits. Isoflavones are the most widely researched compounds in soy. Major isoflavones in the soybean include genistein (which may be the most bioactive isoflavone), daidzein, and glycitein. Isoflavones protect the soybean plant from stress and have antioxidant, antimicrobial, and antifungal actions.Isoflavones are phytoestrogens (estrogen -like substances found in plants) that attach to estrogen receptors in cells. Genistein has been shown to affect many pathways in prostate cancer cells involved in the growth and spread of cancer. How is soy administered or consumed? Soy may be consumed in the diet or taken in dietary supplements. Have any preclinical (laboratory
Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Soy
OverviewThis section contains the following key information:Soy foods (e.g., soy milk, miso, tofu, and soy flour) contain phytochemicals that may have health benefits and, among these, soy isoflavones have been the focus of most of the research.Soy isoflavones are phytoestrogens. The major isoflavones in soybeans are genistein (the most abundant), daidzein, and glycitein.Genistein affects components of multiple growth and proliferation -related pathways in prostate cancer cells, including the COX-2 /prostaglandin, epidermal growth factor (EGF), and insulin-like growth factor (IGF) pathways.Some preclinical studies have indicated that the combined effect of multiple isoflavones may be greater than that of a single isoflavone.Some animal studies have demonstrated prostate cancer prevention effects with soy and genistein; however, other animal studies have yielded conflicting results regarding beneficial effects of genistein on prostate cancer metastasis.Epidemiologic studies have
