Detoxification
  • Leo Galland M.D.
  • Foundation for Integrated Medicine
2
OUR BODIES DETOXIFY
  • Exogenous, foreign substances


  • Endogenous, internally created substances
3
ENDOGENOUS SUBSTANCES
  • Gut toxins
    • bacteria
    • parasites
    • yeast
  • Hormones
  • Bile acids
  • Metabolic intermediates
4
EXOGENOUS SUBSTANCES
  • Xenobiotics
    • herbicides
    • pesticides
  • Air pollutants
    • auto exhaust
    • tobacco smoke
  • Pharmaceuticals
5
DETOXIFICATION TRANSFORMS MOLECULES
  • Functionalization
  • Phase I


  • Conjugation
  • Phase II
6
MAJOR SITES OF
ENZYMATIC DETOXIFICATION
  • Liver
    • most important organ
  • Lung, intestine, kidney & skin
    • demonstrable detox capability
7
LIVER DETOXIFICATION

  • PHASE ONE: OXYGENATION



  • PHASE TWO: CONJUGATION
8
PHASE ONE ENZYMES
  • Cytochrome P450 system (20-30 enzymes)
  • Use oxygen to alter molecules
  • By-products include free oxygen radicals
  • End products may be more dangerous than the initial chemicals
9
 
10
PHASE ONE ACTIVITY
  • Increased in tobacco smokers
  • Increased or decreased by medications
  • Increased by char-broiled meats and high intake of  alcohol, BHT or vegetable oils
  • Variably influenced by phytochemicals, especially flavonoids
  • Decreased in vegans
11
PHASE ONE INDUCERS
  • cabbage, broccoli, brussel sprouts (indole-3-carbinol)
  • oranges and tangerines (limonene)
  • caraway and dill seeds (limonene)
12
PHASE ONE INHIBITORS
  • grapefruit (naringenin)
  • turmeric (curcumin)
  • capsicum (capsaicin)
  • cloves (eugenol)
  • onions (quercetin)
13
"ZINC DEFICIENCY DISRUPTS PHASE ONE..."
  • ZINC DEFICIENCY DISRUPTS PHASE ONE ACTIVITY, SHIFTING ENZYME PATTERNS TO INCREASE THE PRODUCTION OF CANCER PROMOTERS
14
PHASE TWO:CONJUGATION
  • sulfate
  • amino acids: glycine, taurine, glutamine, ornithine, arginine
  • glutathione
  • methylation
  • glucuronic acid
15
PHASE TWO INHIBITION
  • nutritional deficiency
  • toxin exposures that exhaust supplies of substrates or co-factors
  • example: acetaminophen, alcohol and low protein intake deplete glutathione, which is needed for acetaminophen detoxification


16
PHASE TWO STIMULATION
  • cabbage, broccoli, cauliflower, brussel sprouts, kale (glucosinolates)
  • garlic oil, rosemary, soy
  • citrus peel, dill and caraway oils (limonene)
  • curcumin
  • S-adenosyl methionine (SAM)
  • milk thistle (silymarins)
17
Glucosinolates Must Be Hydrolyzed by the Enzyme Myrosinase
  • Glucosinolates (>70 types) are separated from myrosinase in plants, not sprouts
  • Crushing the plant before cooking liberates the active phytochemical
  • Sulforaphane releases nuclear respiratory factor-2 (Nrf2), induces glutathione S-transferase
18
Glucosinolates Must Be Hydrolyzed by the Enzyme Myrosinase
  • Indole-3-carbinol is converted to diindolyl methane (DIM) by acid conjugation in the stomach
  • DIM stimulates CYPA1/1A2, which alters estrone metabolism to reduce estrogenic activity and inhibit growth of breast cancers
19
PHASE TWO GENETICS
  • Genetic variation in the activity of different Phase two enzymes in the liver, brain or intestines may account for disease susceptibility:
  • colon cancer
  • breast cancer
  • Parkinson’s disease
20
ANTIOXIDANT BENEFITS
  • protect DNA and cell or organelle membranes from free radical damage
  • elevate levels of glutathione
  • stimulate immune responses
  • increase activity of tumor suppressor genes
  • inhibit activity of enzymes needed for tumor growth
21
ANTIOXIDANT PROTECTION
  • vitamins E and C
  • carotenoids (carotene, lycopene, lutein)
  • flavonoids
  • selenium
  • glutathione
  • lipoic acid

23
PLANT FUNCTIONS OF
FLAVONOIDS
  • Production stimulated by lack of light
  • Stress:  microbes, heavy metals, ozone, sulfur dioxide, pH changes
  • Inhibit photo-oxidation and microbial growth
24
CLASSES OF FLAVONOIDS
  • Glycosides
    • rutin, hesperidin
  • Aglycones
    • flavonols (quercetin)
    • anthocyanidins (catechin)
  • Proanthocyanidins
    • dimers, trimers of anthocyanidins
  • Tannins
    • polymeric anthocyanidins
25
FLAVONOID EFFECTS ON MAMMALIAN CELLS
  • Potent anti-oxidants
    • quench free radicals
    • chelate transition metals
  • Inhibit oxygenases:  PG synthetase
    • 5-lipoxygenase
  • Alter activity of ION pumps

METHYLATION
  • protects DNA from mutation
  • depends upon methionine (SAM), folic acid, vitamin B12
  • enhanced by dimethylglycine (DMG), choline, betaine
  • CAVEAT: methylation inactivates genes; aberrant methylation may inactivate tumor suppressor genes
32
THE INTESTINES
 AND DETOXIFICATION
  • absorption and excretion of toxins
  • second largest volume of detox enzymes
  • intestinal toxicity stresses the liver
33
DETOXIFYING AGENTS
  • dietary fiber (beans, grains)
  • antioxidants (vegetables, seeds, fruit)
  • Phase Two inducers (crucifers)
  • glutathione enhancers (selenium...)
  • methylation enhancers (folic acid...)
  • spices (turmeric, rosemary)
  • herbs (milk thistle, Ginkgo biloba)
