Raise your hand if you’ve taken a Dietary Supplement?

Quick Facts U. S. adult population. Over 40% used supplements in 1988– 1994, and over 50% in 2003– 2006 Multivitamins/multiminerals are the most commonly used dietary supplements, with approximately 40% of men and women reporting use during 2003– 2006 Dietary supplements have been taken by more than half of American adults; consumers spent $26. 7 billion on supplements in 2009 2011 Survey found that 1 in 4 people take a fish oil supplement

Reasons for Taking Dietary Supplements

Definition of a Dietary Supplement As defined by Congress in the: Dietary Supplement Health and Education Act (DSHEA), which became law in 1994, a dietary supplement is a product (other than tobacco) that is intended to supplement the diet; contains one or more dietary ingredients (including vitamins; minerals; herbs or other botanicals; amino acids; and other substances) or their constituents; is intended to be taken by mouth as a pill, capsule, tablet, or liquid; and is labeled on the front panel as being a dietary supplement.

Regulation of Dietary Supplements The Federal Government regulates dietary supplements through the U. S. Food and Drug Administration (FDA). The regulations for dietary supplements are not the same as those for prescription or over-the-counter drugs. In general, the regulations for dietary supplements are less strict. Dietary supplements are not required by federal law to be tested for safety and effectiveness before they are marketed, so the amount of scientific evidence available for various supplement ingredients varies widely.

Modern Terms Nutraceutical: Coined from “nutrition” and “pharmaceutical”, 1989 by Stephen De. Feleice, MD, founder and chairman of the Foundation for Innovation in Medicine (FIM) “a food (or part of a food) that provides medical or health benefits, including the prevention and/or treatment of a disease”, go beyond supplementation, more therapeutic. Differ from dietary supplements by the following aspects: Nutraceuticals must not only supplement the diet but should also aid in the prevention and/or treatment of disease and/or disorder Nutraceuticals are used as conventional foods or as sole items of a meal or diet Examples: Green Tea, Vitamin D, Lycopene, Phytochemicals, Probiotics, etc

Pharmaceutical Nutrition Scientific Evidence Nutraceutical

Functional Foods: Are similar in appearance to conventional foods and consumed as part of a normal diet Demonstrated physiological benefits and can reduce the risk of chronic disease beyond basic nutritional functions, including maintenance of gut health Academy of Nutrition and Dietetics Definition: All foods as functional at some physiological level because they provide nutrients or other substances that furnish energy, sustain growth, or maintain/repair vital processes. However, functional foods move beyond necessity to provide additional health benefits that may reduce disease risk and/or promote optimal health. Functional foods include conventional foods, modified foods (ie, fortified, enriched, or enhanced), medical foods, and foods for special dietary use

Probiotics

Human Gut Microflora Human GI tract is sterile at birth, microflora develops after birth Colonization rate varies according to factors: Mode of Birth Infant Nutrition Antibiotic Use Diet Age

Microorganisms that reside on and inside humans outnumber somatic cells Influence host metabolism, physiology, gene expression GI contains ~100 trillion microorganisms that represent 1000 separate bacteria, yeasts, parasites Increase in numbers from the mouth to the anus

Probiotics and Gastrointestinal Health Probiotic bacteria are defined as : “live microorganisms which when administered in adequate amounts confer a health benefit on the host” Ingestion of probiotics has been shown to aid in overall gastrointestinal health: Modulating the intestinal flora Decreasing the number of toxin (carinogenic) producing bacteria in the large intestine. Reduce the risk of colorectal cancer Decrease intestinal permeabilty Stimulation of immune functions Improved digestion and absorption of nutrients Synthesis of vitamins

Large Intestine Microflora Ps. aeruginosa Intestinal putrefaction Production of carcinogens Diarrhea, constipation, infections, liver damage, cancer, toxigenesis. Proteus sp. Staphylococci 2 Inhibition of growth of exogenous and harmful bacteria (diarrhoea, IBD, UC, Crohn’s disease, colon cancer) Clostridia Veillonellae Enterococci Digestion/ absorption of undigested foods and minerals E. coli Lactobacilli Stimulate Streptococci immune Bifidobacteria function Bacteroides Lipid lowering 11 No. /g faeces (log scale)

Mechanism of Action in the Context of Cancer 1. Disruption of TJ proteins Primary Tumor 2. Invasion through the ECM (increase MMP-9 activity) Extracellular Membrane 3. Entrance into circulation 4. Metastasis into liver and lungs

Separation of single tumor cells from primary tumor Tight junctions regulate the epithelial barrier function by the apical intercellular junctions formed in normal epithelial cells and tumor cells. Decreased expression of ZO-1 been implicated in cancer metastasis Claudin ZO-3 Occludin ZO-1 JAM ZO-2 Actin Paracellular Space

Lactobacillus sp. Decrease MMP-9 Protein Levels Control L. casei L. rhamnosus MMP-9 Ponceau S MMP-9 Protein (% Control) 120 100 74. 22% * 80 61. 38% * 60 40 20 0 *Indicates (P = < 0. 05) Control L. casei L. rhamnosus

Lactobacillus sp. Increase ZO-1 Protein Levels Control L. casei L. rhamnosus ZO-1 β-actin ZO-1 Protein (% Control) 250 *Indicates (P = < 0. 05) 170. 15% * 200 134. 06% P = 0. 060 150 100 50 0 Control L. casei L. rhamnosus

What does the Data mean? Probiotics play a role in gene expression!!!!!

Probiotics can decrease intestinal permeability which has been implicated in autoimmune disorders such as Thyroid disorder, Celiac Disease, Parkinson’s, Type 1 Diabetes

D-Mannose and Cranberry

Urinary Tract Works with the lungs, skin, and intestines to excrete wastes to maintain homeostasis in the body. Urinary tract infections can occur and are caused by bacteria in the urinary tract. CAUTI, Cystitis (bladder), pyelonephritis (kidney) In the United States, 1 in 5 women report reoccurring UTI, eleven million women receive medication for UTIs annually Treatments include: antibiotics, increasing fluid intake to flush out bacteria

Urinary Tract and Infection “Bacterial adherence to the uroepithelium is recognized as an important mechanism in the initiation and pathogenesis of urinary tract infections (UTI). The uropathogens originate predominantly in the intestinal tract and initially colonize the periurethral region and ascend into the bladder, resulting in symptomatic or asymptomatic bacteriuria. ”

D-mannose and Cranberry d-Mannose is the end product of the digestion of various polysaccharides and glycoproteins found in the diet. d-Mannose is a monosaccharide found in fruits such as apples, blueberries, and cranberries. Cranberries (Vaccinium macrocarpon) contain high levels of d-Mannose as well as proanthocyanins (PACs). Both d-Mannose and PACs have been shown to prevent and treat UTI infections in both men and women

Mechanism of Action E. coli d-Mannose Receptor d-Mannose Cranberry Eroepithelial Cells

Summary Dietary Supplements, nutraceuticals, and functional foods fall under DSHEA and are regulated by the federal government with more lenient standards. Probiotics aid in overall GI Health by mechanisms that affect gene expression, specifically through Tight Junction Proteins and MMP-9 in the context of cancer. D-mannose and Cranberry have been shown to prevent and treat urinary tract infections by preventing pathogenic bacteria from binding to uroepithelium.
