Phenols |
protects
plants from oxidative damage & does same for humans |
fights against
allergies, inflammation, free radicals, ulcers, viruses and
tumors, high blood pressure, platelet stickiness which can
contribute to heart disease. Reduces estrogen production and reduces risk of estrogen-induced cancers. May impair development of cataracts in people with diabetes. |
berries, wine, tea, grapes and purple eggplant |
| Caffeic & Ferulic Acids | May prevent the formation of carcinogens in the stomach | fruits, vegetables, citrus | |
| Carnosol | An antioxidant that may prevent cholesterol oxidation and prevent cancer. | rosemary | |
|
Catechins, Gallic Acids: - differ in chemical structure from other flavinoids but share same chemopreventive properties most common catechins are gallic esters below: |
|||
| -epicatechin (EC) | -neutralize free radicals, may reduce risk of cancer | -green tea (camellia sinensis) | |
| -epicatechin gallate (ECG) | -neutralize free radicals, may reduce risk of cancer | -green tea (camellia sinensis) | |
| -epigallocatechin gallate (EGCG) | -neutralize free radicals, may reduce risk of cancer | -green tea (camellia sinensis) | |
|
Flavonoids -previously referred to as vitamin P -more than 1500 different types including those listed below: |
-green veggies, kale, spinach | ||
| Anthocyanins & Anthocyanidins | -neutralize free radicals, may reduce risk of cancer | -brightly coloured fruits & veggies: berries, eggplant skin, red cabbage | |
| Catechins | -neutralize free radicals, may reduce risk of cancer | -tea, grapes, wine | |
|
Flavanones: -hesperidin -silybin -xanthohumol |
-neutralize free radicals, may reduce risk of cancer | -citrus, milk thistle, beer hops | |
|
Flavones: -apigenin |
-neutralizes free radicals, may reduce risk of cancer | -celery, parsley, apples | |
|
Flavonols: -quercetin -rutin -ginkgoflavonglycosides |
-grapefruit, buckwheat, ginkgo, grapes, wine, onions | ||
|
Phytoestrogens -found in most plant varieties -includes: |
-block uptake
of cholesterol and speed excretion of it from body -may protect vs cancers of the colon, breast and prostate |
-seeds of green & yellow vegetables including: pumpkins, yams, soy, rice and herbs | |
|
Isoflavones: -function much like flavonoids (see below) -includes following types: |
-soybeans & soy-based foods & other legumes | ||
| genistein and daidzein | -may protect vs heart disease and some cancers; may lower LDL cholesterol | -in soy products and herb Kudzu | |
| Lignans |
-Plant
phenolics converted in the intestines to a type of phytoestrogen
("plant" estrogen) with antioxidant properties. As a weak
estrogen, lignans may reduce risk of hormone-related cancers by
tying up the estrogen receptors on cells. -lowers LDL & total cholesterol & triglycerides |
-flax or sesame seeds and flour, rye, whole grain products, vegetables and some berries | |
| Plant Sterols | Stanol Ester | -lowers blood cholesterol levels by inhibiting cholesterol absorption | -corn, soy, wheat, wood oils, nuts, sesame or sunflower seeds |
| Prebiotic & Probiotics | Fructo-oligosaccharides (FOS) | -may improve gastrointestinal health | -Jerusalem artichokes, shallots, onion powder |
| Lactobacillus | -may improve gastrointestinal health | -yogurt, other dairy | |
| Saponins |
-may help
control blood cholesterol, triglycerides and blood sugar -contains anticancer enzymes |
-soybeans, soy foods, soy protein-containing foods, beans | |
| Soy Protein | 25 grams per day may reduce risk of heat disease | soybeans and soy-based foods | |
| Terpenes |
-one of
largest classes -a family of chemical substances in the essential oils of plants -found in many plant varieties -protect plants from oxygen damage that attacks human cells |
-act as antioxidants, protecting fats, blood and other body fluids from free radical damage | -tomatoes, parsley, oranges, pink grapefruit, spinach, red palm oil |
|
Carotenoids: -bright yellow, orange & red plant pigments -includes |
-serves as
antioxidant by neutralizing cancer-promoting free-radicals that
can damage healthy cells -may protect vs lung, breast, colorectal, uterine and prostate cancers |
||
|
-alpha
carotene: |
-antioxidant
that body changes to vitamin A as needed -linked to reduced risk of lung cancer |
-carrots, | |
| -beta carotene |
-antioxidant
that body changes to vitamin A as needed -may play a role in slowing progression of lung and oral cancers |
-carrots, dark leafy greens & other red, orange and yellow fruits & veggies | |
| -lutein |
a powerful
antioxidant and one of two carotenoids found in the eye. These
yellow pigments are believed to filter out harmful blue light
and protect against age-related macular degeneration, the
leading cause of blindness in people over 65 more resistant to cooking than other carotenoids, it's also associated with decreased lung cancer risk. |
green vegetables like spinach and collard greens | |
|
lycopene: gives red color to tomatoes, guava, rosehip, watermelon, and pink grapefruit |
helps reduce risk of macular degenerative disease, serum lipid oxidation and cancers of the lung, bladder, cervix, and skin. | lycopene in tomatos absorbed better from tomato products such as juices, sauces, paste and ketchup | |
| zeaxanthin | helps maintain healthy eyesight | eggs, citrus, corn | |
|
Limonoids: |
it is used
in Japan to dissolve gallstones protects lung tissue |
citrus peels/oils, as well as garlic and the oils of other plants | |
| Thiols |
Organo
or Allylic Sulfides: these compounds are released when foods are cut or smashed includes: |
process
antimutagenic and anticarcinogenic properties, as well as immune
and cardiovascular protection -offer antigrowth activity for tumors, fungi, parasites and cholesterol -activate liver detoxification enzyme systems |
garlic, onions, leeks, shallots, chives, |
| Allyl methyl trisulfide | may boost enzyme cancer detox systems and prevent bacteria from converting nitrates into substances that help make carcinogens | onions, garlic, olives, leeks, scallions | |
| Diallyl sulfide | may boost enzyme cancer detox systems and prevent bacteria from converting nitrates into substances that help make carcinogens | onions, garlic, olives, leeks, scallions | |
| Glucosinolates including isothiocyanates, dithiolthiones, and sulforaphane |
powerful
activators of liver detoxification enzymes and protect vs
cancers of the breast, liver, colon, lung, stomach and esophagus also regulate white blood cells and immune system |
cruciferous vegetables | |
|
Tocotrienols & Tocopherols |
alpha
tocopherol is most common form of vitamin E, found in both body
and in supplements gamma tocopherol is primary source of vitamin E in diet |
tocotrienols
appear to inhibit breast cancer tocopherols do not appear to have the same preventative effect |
in grains |
