What are “functional foods?”
“Whole foods and fortified, enriched, or enhanced foods
have a potentially beneficial effect on health when
consumed as part of a varied diet on a regular basis, at
effective levels….”

Interesting comment on modern diet…
“Antibiotics, disinfectants, and low use of plant
foods may have forever altered our ancient gut
microbiome….Dietary modulation to
manipulate specific gut microbial species may
offer therapeutic approaches.”

Liver Detoxification Pathways
Phase I
Cytochrome P450 or mixed
function oxidase system
(MFOS) activates enzymes
Hormones, prostaglandins and
xenobiotics (toxins) are broken
down, become more water
soluble and ready for
elimination.
Phase 2
Metabolites from phase I are
conjugated in a series of
reactions controlled by
Glutathione-S-Transferase (GST)
and NADPH quinone reductase,
then excreted in the urine or
feces (in bile).
Glutathione: modulates cell death;
blocks carcinogens from damaging
cell DNA; makes carcinogens
easier to excrete
S Escott-Stump
56
Sulforaphane (Isothiocyanate)
Broccoli
Sulforaphane: Antioxidant
Pancreatic ductal cancer stem
cells: sulforaphane + EGCG +
quercetin
Inhibits H pylori infections;
blocks gastric tumor formation
↑ production of the
detoxification enzyme,
Glutathione-S-Transferase
(GST)

Guiding Principles for Counseling
• Apply a “wholeness
orientation” in health
care delivery: mind,
body, spirit, and
environment
• Support and promote
the natural capacity of
recovery and selfhealing
• Disseminate
comprehensive, quality
and timely information
• Recognize the patient’s
right to choose freely
among safe and effective
care or approaches
• White House Commission on Complementary
• Respect the diversity of
all health traditions
and Alternative Medicine
S Escott-Stump
61
Overall: Balanced Diet Approach
• Even natural, whole
foods could be
troublesome if overconsumed
• More is NOT ALWAYS
BETTER
Advice to the
Registered Dietitians
S Escott-Stump
62
Overall: Safety
Botanical supplements
are not regulated by the
Food and Drug
Administration
• Any biologically active
ingredient, consumed in
excess, can be harmful.
“Natural” does not
guarantee safety -SNAKE VENOM is
natural…
S Escott-Stump
63
Overall: Choose Where You Stand
• Guiding
• Make
suggestions?
• Promoting
• Back a product,
food or
supplement?
• Help client to
reach own
conclusion?
• Encourage use?
© S. Escott-Stump
Overall: Be a Client Advocate
• Identify and document
use of herbs and
botanicals
• Discuss with physician.
• Advocate for better
regulation of herbs and
botanicals as drugs,
not foods
64
S Escott-Stump
65
Polling Question
• After this webinar, how likely are you to discuss specific
phytochemicals for improving health?
• Very likely
• Likely
• Somewhat likely
• Plan to review the literature again
S Escott-Stump
66
REMEMBER Our Professional Goal!
Let’s ensure that the
public has not only
great nutrition tips but
accurate information!
