Paleo Objectives • Explain Paleo eating and its origins. • Describe foods that are included in the Paleo plan and those that are excluded. • Discuss how this type of eating style may or may not benefit our patients. Clip Art
Basic Principles of the Paleo Lifestyle • Eat whole foods. • Avoid processed, refined foods. • Eat for proper digestive functioning. • Eat for good blood sugar regulation. • Individualize the plan to meet health needs/goals. • This is not a “One size fits all” approach! Clip Art Clip Art
Paleolithic Diet Origins • Prior to Agriculture ~10,000 years ago • 333-400 generations ago • No grains, legumes, farmed-raised/grain-fed animals • We ate this way for 2.5 million years: • Lean game meat/poultry/fish + vegetables/fruit • Determined by • Fossil Records • Current Hunter-Gatherer Diets • Chimpanzee diets (We share ~98% of the same DNA.) • Nutrients in wild animals and plants Cordain, Loren. The Paleo Diet, revised edition. Houghton Mifflin Harcourt: Boston, NY; 2011. Clip Art
Paleolithic Diet Origins • Discordance or Mismatch Hypothesis: The human genome evolved to adapt to conditions that no longer exist. Dietary changes have occurred faster than adequate genetic adaptation could respond. This mismatch between genome and diet has resulted in today’s chronic disease. Konner M, Eaton SB. Paleolithic Nutrition: Twenty-Five Years Later. Nutrition in Clinical Practice. 2010; 25(6):594-602. Clip Art
Paleolithic Evidence • Hunter-gatherers of today do not suffer from modern diseases (DM, obesity, HTN, CVD, OA, high cholesterol). • Pima Indians in America vs in Mexico • Australian HGs with T2DM – improved health s/p return to former lifestyle/diet . Konner M, Eaton SB. Paleolithic Nutrition: Twenty-Five Years Later. Nutrition in Clinical Practice. 2010; 25(6):594-602.

Paleo Exclusions • Processed FoodsReasons We Tend to Include • High in sugar, fat (trans/saturated), and salt *Enjoyment, celebration • Low nutrient-density, High caloric-density *Easy/Quick • Oils when in high heat (deep fried) toxins*Cultural traditions • Sugar, Salt, Vinegar, Alcohol • Grains • Easily become excessive in diet *Contributes to daily fiber • If not used wt*Contributes to B9, B1, B2, B3 • High in Lectins*Inexpensive staple food • High in Phytates*Cholesterol-lowering fiber • Legumes • High in Lectins*Contributes to daily fiber • High in Phytates*Cholesterol-lowering fiber • If not appropriately cooked toxins*Inexpensive Protein • Dairy (including Butter) • USA: A1 or A2 Beta Casein *Major source of daily Ca & Vit D • Lactose intolerance *Probiotics • Allergies Clip Art
Lectins • Lectins = Phytohemagglutinins = Phytagglutinins • Glycoproteins that may serve in the following: • Recognition and binding of nitrogen-fixing bacteria to legume roots. • Defense mechanism of plant’s seed • Resistant to Proteolytic Digestion (wheatgerm, tomatoes, and navy beans) Antibodies • Known to agglutinate RBCs. • > 400,000 kidney bean lectin binding sites on surface of each RBC (phytohaemoglutinin). • Do not eat raw kidney bean sprouts! • Effects in Animals: Reduced growth rate, diarrhea, interference with nutrient absorption, GI ulcers http://www.ansci.cornell.edu/plants/toxicagents/lectins.html
Lectins, Phytates, Enzyme Inhibitors in Legumes, Grains, & Nuts/Seeds • Differing Lectin Levels /Toxicity • Fungal infection/wounding of plant increases lectins. • Environment (weather, soil, location, season). • High levels in grains (wheat in particular) • Rinse/soak/rinse quinoa to help rid it of saponins • High levels in legumes (beans, lentils, soybeans, peanuts) • Peas and green beans are considered safe http://www.ansci.cornell.edu/plants/toxicagents/lectins.html
Lectins • Certain seaweeds and mucilaginous vegetables have the ability to bind lectins in a way that makes them unavailable to the cells of the gut. • Lectins are resistant to dry heat, so using raw legume flours in baked goods should be done with caution. • The “Blood Type Diet” is based on how our blood cells react with lectins in foods. • Some experts hypothesize that it’s no coincidence the top 8 allergens also contain some of the highest amounts of lectins (including: dairy, egg, wheat, soy, peanuts, tree nuts, fish, shellfish). • Some experts theorize that lectins cause urinary tract infections. • Some experts theorize that the reason anemia is higher in developing countries is due to excessive levels of lectin consumption.

Dairy Issues? http://a2milk.com.au/beta-casein/beta-casein-milk-protein/ http://a2milk.com.au/beta-casein/beta-casein-milk-protein/
A2-Beta-Casein A2 beta casein = original beta casein gene. *Milk from cattle thousands of years ago, before large-scale domestication = A2 Milk. A1 beta casein = from genetic mutation *Digestion of A1 beta casein can result in the production of bioactive beta casomorphin-7 (BCM-7). BCM-7: oxidizes LDL -Trials have shown A1 beta casein elicits biological effects in animals which lead to heart disease. Clip Art
A1 Beta Casein BCM-7 Epidemiological studies in several developed countries show strong correlations between A1 beta casein and the following: -incidence of type 1 diabetes mellitus -heart disease mortality rates (oxidizes LDL) -aggravation of neurological disorders (autism and schizophrenia) Clip Art

Application to Our Patients? Clip Art • GI Complaints: May serve as a place to start for elimination diets. • Epilepsy: Low-carb Ketogenic diets decrease frequency of seizures. • Obesity/Overweight: Weight loss • Chronic Disease Improvement • Compliance may be difficult even with most motivated individuals. • Not the most sustainable, ecological, or economical diet. Clip Art Clip Art
Basic Paleo Principles are in compliance with a healthy lifestyle • Eat whole foods. • Avoid processed, refined foods. • Eat for proper digestive functioning. • Eat for good blood sugar regulation. • Individualize to meet health needs and goals. • Consider Probiotics and Vitamin D supplements • Vegetarian: add back sprouted seeds • Add back A2 beta casein Dairy • Adjust Carbsto Meet Physical Activity Demands
