The Power of Nutrigenomics:
A Practical Guide for Application in theTreatment of Chronic Illness
Advances in the understanding of genetics are changing the wayhealthcare professionals think about disease causes and prevention. It'snow accepted that a person's state-of-health arises from the dynamicinteraction of environmental factors with his or her genetic uniqueness.And, nutrition has emerged as a primary environmental factor that canpositively or negatively impact the extent to which a person will realize
his or her genetic potential.
Nutrition research in the past has focused on nutrient deficiencies andimpairment of health.1But the Human Genome Project has led to theconcept of personalized medicine not only with drugs(pharmocogenetics), but with nutritional modalities as well.1-4Nutritionalgenomicsor nutrigenomicsis the junction between health, diet, andgenomics.1In other words, nutrigenomics is the effect that nutritivesubstances and phytochemicals have on genetic expression withinhuman cells.
As a growing field of research, nutrigenomics is the recognition of theability to optimize nutrition for maintaining and extending a state ofoptimal health.5This growing field of research has demonstrated the
effects that nutrients and botanicals can have on modifying geneexpression, prompting the development of research-basednutraceuticals, functional foods, and dietary approaches to addressdisorders in genetically pre-disposed individals.2,3,5
The Future of Health CareHere Today
New developments in nutrigenomic research are predicted to offerenormous potential for the development of dietary optimizationapproaches.
5But you wont have to wait for therapies applying basic and
advanced nutrigenomic principals to benefit the health of your patients.Theyre already here.
Nutrigenomics in clinical practice entails using specified, defined
nutrients and nutritional programs to target genetic expression forimproved patient outcomes without serious adverse effects. These new,patient-centered approaches to health care rely upon nutrition and othermodifiable lifestyle factors to help people achieve optimal geneticexpression.

3-Phase Plan for ImplementingNutrigenomics
You can easily tailor and prescribe a program for patients presentingwith a variety of common and chronic health conditions. A nutrigenomicapproach to wellness can include any or all of the following:
1A. Dietary Signal Modification with TLCWestern diets, foods of convenience, and other unhealthydietary habits can muddle the signals sent to cells throughoutthe body, fostering negative genetic (phenotypic) expressionthat leads to premature aging and disease. What people eat,therefore, may have a direct influence on how they feel. Andaddressing those eating patterns allows your patients tomanage symptoms and even halt or reverse the progression oftheir illnesses.
You can help them make informed decisions that impact theirhealth by offering therapeutic lifestyle changes (TLC). TLC canprovide food plans that incorporate nutrigenomic principles for abroad population, then further customize these plans based onpatient response, individual concerns, and specific nutritionalneeds.
1B. Dietary Signal Modification with Medical FoodsMedical foods offer an adjunct approach to dietaryrecommendations to nutritionally manage specific conditions. Amedical food is formulated with macro- and micronutrients thatare recognized by scientific principles to support the dietarymanagement of a disease or condition, and is to beadministered under the supervision of a physician or licensedhealthcare practitioner.
Medical foods contain nutrients that typically cannot be acquiredthrough normal dietary measures. Some patients may require alevel of nutritional support that simply cannot be met by even afood plan with the best intentions. Medical foods offer apowerful tool, yet can be very simple to implement in yourpractice.
2. Selective Kinase Response Modulators (SKRMs)Dietary signals are translated by enzymes known as kinases atthe cellular level, helping to direct genetic expression. Selectivekinase response modulatorsor SKRMsare nutritionalsubstances that can work to modulate kinase signaling backinto balance, helping to restore healthy signaling to genes,favorably affect genetic expression, and reverse the effects ofchronic illness.
Adopt a simple, 3-phase plan
for applying nutrigenomics in
your practice.

Where an unhealthy diet makes the kinase signaling unclear,SKRMs help increase the volume of the message for positivegenetic expression and preservation or restoration of health.These research-based nutritional substances offer the newestavenue for a natural approach to wellness that embodies theideals of nutrigenomics.
3. Targeted Nutritional SupportEven the most comprehensive approach to wellness mayrequire additional nutritional support for maintaining health,addressing specific symptoms, or customizing approaches forpatients with multiple health concerns.
Outlined here are just a few approaches of the hundreds ofpossibilities for targeted nutritional applicationsfrom additionalsupport for joint protection and restoring healthy gut ecology tomaintaining healthy hormone balance and blood sugar levels.

Phase 1AChanging Primary Dietary Signals with TLC
The first step in a nutrigenomics intervention is changing primary dietarysignals. Foods contain nutrients serving as dietary signals that travel tocells throughout the body, where they are translated by kinases. Healthyfood choices foster healthy signaling. Poor food choices, however, cantrigger a disorder of kinase signaling, resulting in poor geneticexpression and, ultimately, chronic illness.6,7In fact, poor nutrition is oneof the three leading factors attributed to 70% to 90% of mortalities fromchronic illnesses in the U.S. alone.8
Prior to the commercialization of the Western diet, humans (overcenturies) developed a relationship with commonly eaten foods. Existingin harmony with these foods meant dietary signals that were adequate tomaintain health. Changing the diet with commercialized foods andintroducing foreign substances creates a state of cellular stress wheremessages can be distorted and negatively affect physiological function.6But these negative dietary signals dont have to be a part of modernliving, nor do the long-term costs of premature aging and chronicdisease development.
Figure 1. The nutrients (or lack thereof) and other foreign substances (xenobiotics) ina diet can both directly and indirectly influence genetic expression, impacting health.
Unhealthy diets are a leading
cause of chronic illness

How can you help modify your patients dietary signals? This can beaccomplished through therapeutic lifestyle changes (TLC). Scientificevidence in support of TLC programs as a fundamental therapy forchronic conditionsincluding cardiovascular disease (CVD), type 2diabetes, and obesitycontinues to grow.7,9-21
An optimal TLC program should include recommendations for exercisefor a comprehensive approach. It should also provide the means andflexibility for further personalization of condition-specific support withnutrients that may not be possible to obtain through dietary measuresor difficult to obtain in therapeutic amounts. Medical foods (Phase 1B onpage 10) are designed to complement dietary approaches for thenutritional management of specific conditions.
Help for Implementing Dietary Signal Changes
The responsibilities of a patient change in the management of chronicdisease. Because the patient takes on a caretaker role in the treatmentprocess, greater educational efforts are needed for successfuloutcomes.
22,23Unfortunately, many practices are set up for acute
disease management rather than chronic illness care, and may not beprepared to institute efforts such as lifestyle modification programs.
23
FirstLine Therapyis an example of a TLC program that can helphealthcare practitioners teach their patients how to adopt dietarychanges that can positively affect kinase signaling to support geneticexpression, befitting a longer, healthier life.
The FirstLine Therapyfood plans are based on a traditionalMediterranean-style eating plan that has an overall low glycemic load(for balancing blood sugar), low in arachidonic acids (anti-inflammatory),and high in phytonutrients. Moreover, the foods have been screened fora history of safe use and for unique molecules that have the ability tomodulate kinase signaling in a positive manner. These foods affectsignal transduction to help increase the clarity of messages sent tokinases, creating a potential to combat chronic disease and restoreoptimal wellness. A disordered physiology will respond to these newsignal conductors, reducing the burden of prior unhealthy eating habits.
For optimal support, these dietary changes may be customizedthrough tailored food plans and medical foodsto meet the specificneeds of patients, such as those with conditions related to insulinresistance, cardiovascular disease, autoimmune disorders, inflammatoryconditions, fatigue syndromes, and hormone imbalances.

Cardiovascular & Insulin Resistance Conditions
Many conventional dietary programs recommended by leading
health organizations are lowfat, high-carbohydrate diets designed tolower elevated cholesterol levels. However, individuals on thesediets may eat high-glycemic-index foods that can cause spikes inblood sugarincreasing hunger, decreasing satiety (feeling offullness), and fostering insulin resistance and a variety of relatedhealth problems. Most importantly, these diets may not produce thedesired results.19
Dietary choices causing a high insulin response have been linked tothe development of metabolic syndrome, type 2 diabetes, andcardiovascular disease (CVD).12,24-26Research has demonstrated,for example, that the Western dietalso referred to as the StandardAmerican Diet (SAD)modulates kinases and insulin signaling.27
Science-based recommendations include reducing consumption ofhigh-glycemic-index foods (e.g., simple sugars, processed andsnack foods) and/or replacing them with low-glycemic-index fruits,vegetables, and whole grains.
12,28-30This also adds fiber for a lower
overall glycemic load (GL).26
A low-GL food plan promotes healthy blood sugar and energy levelsin your patients. Research also links insulin resistance to CVD risk(as is the case in metabolic syndrome), making this an appropriateeating plan for cardiovascular disease.13,19Low-GL diets have alsobeen shown useful in conditions involving inflammation andoxidative stress, reinforcing its application for CVD patients.
21,31
Inflammatory, Gastrointestinal, Autoimmune & Fatigue Disorders
Diet may also represent a significant immune-modulating part of apatients environmental exposure. An increasing body of researchsuggests that chronic or recurring inflammatory disorders may bereactions to substances that trigger an immune response from thegastrointestinal (GI) tract. Dietary changes may have a noticeableimpact on modifying the underlying inflammatory signals that areassociated with autoimmune disorders. Scientific studies havedemonstrated the effectiveness of dietary therapies in alleviating thesymptoms and even in altering the progression of inflammatory andautoimmune conditions.
31-49
Research suggests that many common inflammatory and
gastrointestinal conditions are triggered by sensitivities or reactionsto certain foods and that removing these offending foods mayprovide relief.32-49Broad guidelines for eliminating common foodsthat trigger inflammation can be customized as patients slowly

challenge the reintroduction of foods to determine those that mayexacerbate symptoms.
A low-GL diet has also been shown to be beneficial in reducingoxidative stressthe overproduction of damaging free radicalsassociated with chronic fatigue syndrome and conditions such asrheumatoid arthritis and inflammatory bowel disease (IBD).
31Low-
GL foods that are rich in antioxidantsberries, red grapes, garlic,spinach, whole grainscan help restore the bodys balance ofantioxidants and combat harmful free radicals generated byenvironmental toxins, inflammation, and unhealthy lifestyle habits.
While a modified elimination diet may provide an approach for long-term condition and symptom management, sometimes a moreaggressive, non-fasting dietary approach may be warranted. Somesymptoms of chronic fatigue syndrome, for example, may beimmediately relieved through a liver detoxification program featuringa more aggressive elimination diet for a shorter term.
Hormone Imbalances & Cyclerelated Symptoms
In both men and women, unhealthy diets are one of the manyfactors that influence the bodys ability to balance hormones.Additionally, foods and beverages can include exogenous sourcesof hormones that overload the bodys natural ability to detoxify andexcrete them.
Estrogen imbalance in women, for example, may manifest aspremenstrual syndrome, irregular menstrual cycles, fibrocysticbreast disease, endometriosis, or dysmenorrhea, as well as fostersymptoms that impact daily livinghot flashes, night sweats, anxietyattacks, and mood fluctuations.
Targeted dietary changessuch as the inclusion of cruciferousvegetables and adaptogenic phytoestrogens like soycan supportthe bodys production, use, and excretion of various hormones,particularly estrogen. These dietary changes can positively affectthe detoxification of circulating estrogens, thereby creating a positiveestrogenic influence on activities at the cellular level.

Phase 1BChanging Primary Dietary Signals with
Medical FoodsFood plans and other lifestyle changes may only provide part of therecommendations for changing dietary signals for optimal healthsupport. Medical foods, ever increasing in use, provide an idealcomplement to dietary changes to help modify kinase signaling forpatients presenting with a variety of conditions, such as those related todysglycemia and inflammation. Medical foods contain therapeutic levelsof nutrients that would be difficult, if not impossible, to achieve throughtraditional dietary means to support specific conditions.
For almost two decades, Metagenics has been one of the fewcompanies to develop and manufacture medical foods. The genesis ofthese medical foods was based on burgeoning research now known as
nutrigenomics. These medical foods are backed by numerous clinicalstudies and extensive peer-reviewed scientific support.
For added assurance and developmental research purposes, thesemedical foods undergo continual testing in a clinical setting at theFunctional Medicine Research CenterSM(FMRC), the clinical researcharm of Metagenics.
The SKRM Effect: Creating the Next Generation of Medical Foods
Medical Foods with the inclusion of SKRMs offer a multi-mechanisticapproach to offer even more opportunities for patient success. Theyrepresent the latest in medical food development, incorporating
nutrigenomic research and technology for a new degree of healthsupport. (For more information on SKRM research, please see Phase2Modulating Kinase Signaling with SKRMs on page 18.)
The following medical foods are intended to complement dietaryrecommendations to offer nutritional support for the management of
specific conditions. Healthcare practitioners, however, are best qualifiedto decide on a case-by-case basis when other patients may alsobenefit from the nutrients provided by formulas designed to address:
Metabolic syndrome
Cardiovascular disease
Inflammatory bowel disease (autoimmune support)
Type 2 diabetes Chronic fatigue syndrome (liver detoxification support)
Premenstrual syndrome (hormone balance)
Leaky gut syndrome
Medical foods provide
powerful signaling nutrients
not found in typical diets.
Medical foods containing
SKRMs offer a multi-
dimensional approach to
wellness.

Phase 2Modulating Kinase Signaling with SKRMs
Nutrigenomic research, such as that conducted by the MetaProteomicsNutrigenomics Research Center, attempts to discover highly activesubstances from food and other natural sources that can serve as potentdietary signaling molecules to positively affect genetic expression.Optimally, this yields the development of unique food ingredient extractsfrom which individual bioactive molecules can be isolated and tested fortheir ability to modify cellular function related to various diseaseprocesses.
Many prevalent health issues have been found to have specificunderlying kinase signaling components. This is due to the ability ofkinases to translate dietary signals in a positive or negative manner toinfluence health. For example, research has shown that impaired kinase
signaling can lead to impaired insulin response and hyperlipidemiaassociated with type 2 diabetes.59
Kinases are enzymes that chemically modify other proteins and regulatethe majority of cellular pathwaysparticularly those involved in thetransmission of intracellular signals. These enzymes also help regulateeicosanoids, cytokines, reactive oxygen species, and other mediatorsthat may negatively impact the body both locally and systemically.
Figure 4. SKRMs positively affect kinase signaling for optimal genetic and phenotypicexpression for wellness. SKRMs are an ideal complement to positive dietary changesfor restoration of healthy kinase activities.

As mentioned previously, SKRMs are nutritional substances that canwork to modulate kinase signaling back into balance. This balance helpsrestore healthy signaling to genes for positive genetic expression andreversal of illness.
Proprietary research has yielded the discovery of food-derived SKRMsthat specifically inhibit kinase-mediated processes associated withinsulin resistance and inflammation. SKRMs may offer therapeuticadvantages over dietary modifications alone.
Insulin SKRMs
Groundbreaking preliminary research suggests the identification ofSKRMs that have the ability to improve insulin sensitivity by modulatingspecific kinase enzymes that serve as hubs for insulin-signalingprocesses.
More than 200 natural substances and extracts were tested for theirinfluence on insulin responses and adipocyte (fat-storing) cells at theMetaProteomics Nutrigenomics Research Center. A combination ofreduced iso-alpha acids (RIAA) derived from hops (Humulus lupulus)and acacia extract (Acacia nilotica) was shown via in vitrotesting toinhibit inflammatory markers that influence insulin function.
60
Research has implicated dysregulated inflammatory processes in thedevelopment of insulin resistance, and several inflammation-inducedcytokines have been shown to be expressed during insulin resistanceand metabolic syndrome.61-63Cytokinessuch as interleukin-1 beta (IL-
1), tumor necrosis factor alpha (TNF-), and interferon gamma (IFN-
)have been shown to play a role in cytokine-induced -celldysfunction in diabetes.64,65
In human clinical testing at the Functional Medicine Research Center,supplementation of metabolic syndrome subjects with a combination ofRIAA and acacia led to greater reduction of 2 h pp insulin levels, ascompared to placebo. Furthermore, greater decreases of fasting insulin,fasting and 2 h pp glucose, fasting triglyceride, and HOMA scores wereobserved in subjects taking RIAA/acacia supplement versus subjectstaking placebo. These collective results indicate RIAA/acaciasupplementation might be useful in maintaining insulin homeostasis insubjects with metabolic syndrome.

Blood Sugar Metabolism Support
Ever-growing research continues to show the newly discovered benefitsof green tea and cinnamon in complementing dietary approaches toblood sugar management. Insulin resistance conditions can also induceoxidative stress that can lead to vascular complications, such asneuropathy.
CinnamonCinnamon has been shown to display insulin-enhancingactivity in vitro and shown in human clinical trials to positivelyinfluence glucose levels.
106-108Extracts of cinnamon have also been
shown to activate insulin receptor kinase and inhibitdephosphorylation of the insulin receptorleading to increasedinsulin sensitivity.
Green Tea (EGCG)Green tea contains epigallocatechin gallate(EGCG), a bioflavonoid shown to protect pancreatic islet cells and
enhance insulin sensitivity.
109
Catechins from green tea also providestrong antioxidant protection.110
Liver Detoxification Support
There are two primary phases in the detoxification process. In Phase I,fat-soluble toxins are transformed into intermediate compounds that aremore reactive, but will bind more easily to non-toxic, water-solublemolecules in Phase II. In Phase II, formation between the reactiveintermediates and water-soluble molecules make the entire compoundready for excretion out of the body. Targeted nutrients can influencedetoxification activities in either phaseor sometimes both.
SilymarinThis active constituent of milk thistle (Silybum marianum)is well-recognized for its beneficial effects on protecting the liverfrom toxins and stimulating liver regeneration, as well as itsantioxidant properties. Preliminary research also indicates that itmay influence Phase I and Phase II enzymes, and therefore may becalled a bifunctional modulator.
111,112
CatechinsThese strong antioxidants have the capacity toscavenge most oxygen free radicals.
110Also derived from green tea
(Camilla sinensis, see above), catechins enhance the induction ofPhase II enzymesglutathione S-transferase and quininereductaseand inhibit the overinduction of specific cytochromeP450 Phase I biotransformation enzymes.
113,114
WatercressGlucosinolates found in watercress (Nasturtiumofficinale) are precursors of phenythyl isothicynate (PEITC), whicheffectively inhibits the overinduction of specific sytochrome P450

enzymes and enhances Phase II glutathione S-transferase andquinine reductase.115-117
Ellagic AcidNaturally found in pomegranate fruit (Punicagranatum), ellagic acid beneficially modulates Phase Ibiotransformation and enhances Phase II glutathione S-transferaseand quinine reductase enzyme induction.
118-120Also scavenges
superoxide radicals and hydroxyl radicals, reducing hepaticoxidative stress.
120,121
Note: Catechins, watercress, and ellagic acid also influence geneticexpression of enzymes that control Phase II conjugationreactions.113-120
Artichoke LeafExtracts from artichoke (Cynara scolymus) have along history of traditional use in promoting liver function. Researchsuggests that several constituents of artichoke, including
chlorogenic acid and cynarin, have marked antioxidant andhepatoprotective properties.122-124
Intestinal Support
Probiotic strains have specific characteristics that determine whetherthey have the ability to benefit the intestinal environment. But not allgenera, species, and strains are suitable for all purposes. Following arebeneficial bacteria shown to adhere to the intestinal lining and support ahealthy balance of microflora.
125-130
Lactobacillus acidophilus NCFMThis strain of human origin has
been proven safe and effective by more than 60 scientific studies
and almost 30 years of commercial use. It produces lactic acid,hydrogen peroxide, and other natural substances while modulating
the activity of enzymessuch as -glucuronidase, nitroreductase,and azoreductaseto positively influence the balance of intestinalbacteria and support intestinal tissue health.
125Its also one of a
limited number of Lactobacillus species shown to adhere in theintestines.
131
BifidobacteriumThis major group of carbohydrate-metabolizingbacteria in the intestines (including B. lactis) is 1000 times moreabundant than lactobacilli in healthy adults (and some researchersbelieve more important as well).
132 Bifidobacteria have proven
effectiveness as immunosupportive agents that enhance hostresistance, as well as produce strong acids (e.g., acetic, lactic) that
positively affect intestinal pH; thereby, playing a critical role inmodulating ammonia, phenol, steroidal, and other toxin levels tomaintain health and support intestinal microbial balance.

Note: Scientific identification of strains is not only an indicator ofpredicted safety, but assures the means for providing optimal healthbenefits.
Joint Inflammation Support
Many inflammatory and autoimmune conditions are characterized bypain and motility concerns related to the joints. Glucosamine andchondroitin sulfates, as well as MSM, offer widely accepted approachesfor maintaining healthy connective tissue and relieving pain associatedwith concerns that affect a growing number of patients.
Glucosamine & ChondroitinThese nutrients are naturally found inhealthy tissue and work together in forming healthy joint matrixcartilage and enhancing joint lubrication.133,134They may alsopromote the incorporation of sulfur into cartilage. Sulfur is necessaryfor the synthesis of collagen and improves the moisture content ofcartilage, supporting its shock-absorbing ability.135Supplementationwith glucosamine and chondroitin can help restore normal jointmotility and relieve pain.
133,135-138Continued use is required to
maintain benefits.
Methyl-Sulfonyl-Methane (MSM)This natural compoundcomplements glucosamine and chondroitin sulfates, and alsoprovides a highly biologically valuable source of sulfur. MSM hasbeen widely used to support joint health and relieve pain as aneffective natural analgesic and anti-inflammatory agent.
139A
randomized, placebo-controlled trial showed that MSM improvedsymptoms of pain and physical function in patients withosteoarthritis.140Another randomized, double-blind, parallel,
placebo-controlled trial also showed that MSM significantly improvedthe signs and symptoms of osteoarthritis. Furthermore, thecombination of glucosamine and MSM showed better efficacy inreducing pain and swelling and in improving the functional ability ofjoints than the individual agents.139
Hormone Balance Support
Phytoestrogens are plant compounds that have structural and functionalsimilarities to estrogen.
55,141Selective estrogen receptor modulators
(SERMsnot to be confused with SKRMs) are non-steroidalcompounds capable of binding to the estrogen receptors and influencingtheir activities. Specifically, SERMs are noted as being both agonists (in
cases of low estrogen levels, such as with menopause) and antagonists(in cases of high estrogen). Because they support a moderate level ofestrogen activity, upon binding to the estrogen receptors they inhibitendogenous estrogen when too much is present, but can still supportestrogens important functions.142-144

Kudzu & Red CloverProvide a varied profile of non-soyisoflavones and isoflavone glycosidesincluding daidzein,genistein, puerarin, and fromononetinthat bind to the estrogenreceptor and may act as weaker estrogens, resulting in an inhibitionof the estrogenic effect.50,144-146
TurmericCurcuminoids, the active component in turmeric(Curcuma longa), induce glutathione production and glutathione-Stransferase activityhelping to protect tissues from reactiveestrogen metabolites.
147In combination with isoflavones, curcumin
shows in vitro evidence of reducing xenoestrogens-induced growthin estrogen receptor-positive and negative cancer cells, therebypromoting breast health.55,148
Resveratrol (from Polygonum cuspidatum)Classified as a SERMbased on its ability to bond to estrogen receptors and act as both anestrogen agonist and antagonist. Resveratrol provides many other
benefits, including cardioprotective properties.
149
Resveratrol hasbeen shown to promote healthy cytokine production by influencingthe cyclooxygenase and 5-lipoxygenase pathways. It is alsoassociated with reduced activity of nuclear factor kappaB (NF-B)a transcription factor that may promote the expression ofundesirable genes. Resveratrol has potent antioxidant activity(especially in lipids that are highly concentrated in brain tissue),promotes healthy blood flow, and induces hepatic phase IIdetoxification activity.
Stabilized Indole-3-Carbinole (I3C)This naturally occurringcompound found in cruciferous vegetables protects estrogen-sensitive tissues by promoting the formation of 2-hydroxyestrone,diindolymethane (DIM), and other beneficial estrogen metabolites. It
supports the detoxification of estrogens, other steroid hormones,and xenoestrogens by enhancing the activity of enzymes involved intheir metabolism and excretion. Research indicates great promiseas a natural hormone-balancing agent.
150-157
Note: Natural-source I3C may be an important consideration whenrecommending supplementation to patients.
