Federation of Quebec Maple Syrup Producers: states that Canadian maple contains 20 antioxidant compounds that slow cancer growth ○ EGCG: antioxidant found to counter carcinogen effect ■ Found in tea - not FDA approved ○ Resveratrol: potential cholesterol reducing properties ■ Found in grapes ■ Anticancer properties ○ Anthocyanins: found in black raspberries ■ Black raspberries can prevent esophageal tumours in rats ■ Ex: Peaches and plums ■ Purple tomato: GMO’d tomato with a gene from the snapdragon flower to produce more anthocyanins ● Contains 450mg = 1 cup blueberries ● Mice that are given this juiced live longer ■ Nurses’ study noted athocyanins benefits with 35mg/day ○ Isoflavones: estrogen-like compounds found in soybeans that blocks estrogen from causing cancer ■ Genistein: found in soybeans, which are linked in breast cancer reduction when consumed around puberty ● Most breast cancers are estrogen drive, triggered by the hormone ○ Lignans: estrogen-like compounds with antioxidant properties found in plants ■ Ex: flaxseeds ■ Dr. Lilian Thompson at Uof T: investigated breast cancer by giving patients muffins with 25mg of flaxseeds
● Findings: Reduced tumour growth similarly to preoperative tamoxifen Video 6: ● Prostate cancer: most common cancer in men ○ Canada: 20,0000 cases every year, with 20% eventual deaths ■ Most men die with it rather than due to it because it is slow-growing ○ Prevention: ■ Tomatoes: rich in lycopene, which creates the red pigment, found in watermelon and grapefruit as well ● Wayne State lycopene trial - human intervention study: 15 patients were given lycopene twice daily for three weeks before prostate surgery ○ Findings: tumours were smaller and showed reduced malignancy in comparison with placebo ● Health Professionals Follow-Up Study - cohort study: ~50,000 men were compared, those consuming less than 1.5 servings per week of lycopene products ○ Findings: ■ Those eating 10+ tomato servings had a 35% reduction in prostate cancer risk ● Studies show that people who consume a lot of garlic reduce risk of certain cancers ○ Allicin: compound formed when garlic is chopped and cooked ■ Studies found a reduced incidence of stomach cancer ■ Mediterranean countries with a high amount of garlic in diet have a lower risk of stomach cancer ● Turmeric: active ingredient is curcumin; researched for cancer and Alzheimer’s ○ India: low risk of Alzheimer's in comparison to NA ■ Possibly linked to curry and curcumin consumption ● Broccoli: possibly the only food seen as an official anticancer food ○ Contains glucoraphanin ■ When cooked or chewed, sulforaphane is produced ● Induces the formation of phase-2 enzymes in the body ○ Phase-2 enzymes: tie up potential toxic materials and removing them from the body - including carcinogens
■ Animal study - Rats fed sulforaphane after exposure to a carcinogen ○ Findings: ■ 70% of the controls developed cancer ■ 35% of the sulf. Group developed cancer ■ Broccoli Sprouts: young, sprouting broccoli; contains ~50x more sulf.
