Hi! I originally started eating paleo because of stomach problems and I've stuck with it because it makes me feel great. I am also a co-organizer for NYC's Eating Paleo in NYC Meetup Group. I was recently featured in the New York Times in an article about caveman-style life in NYC.
Evolutionarily Appropriate, "Paleo" Foods
The best choices are at the top
| Food | Type | Pros | Cons |
|---|---|---|---|
| Sardines | Seafood | omega-3 fatty acids, sodium, iodine, lower on food chain = fewer environmental contaminants | potential environmental contaminants |
| Buffalo | Meat | Grassfed = higher in omega-3 fatty acids and lower in omega-6, sustainable, wild, no drugs or hormones, high in iron | |
| Wild Boar | Meat | Truly wild boar is sustainable, especially since it is an invasive and destructive species in many areas. High in healthy fats. | farmed wild boar is often fed grain, which makes it too high in omega-6 fatty acids, really only good if it is actually wild wild boar. Relatively lean, so you can't cook it like regular pork. |
| Oysters | Seafood | zinc, iron, calcium, vitamin A, taurine, B12 | environmental contamination |
| Wild Salmon | Seafood | Bioavailable omega-3 fatty acids, vitamin D, Alaskan fishery highly sustainable | Potential environmental contaminants |
| Wild Shrimp | Seafood | Omega-3, minerals, tryptophan, vitamin D, protein | Environmental contamination, common allergen |
| Pastured Lamb | Meat | Good omega-3 to omega-6 ratio, CLA, tons of vitamins and minerals | |
| Shiitake mushrooms | Fungi | close to being a wild food, lentinan compound may strengthen immune system, antioxidants, | |
| Grassfed and Finished Beef | Meat | Part of sustainable agricultural system, relatively high in omega-3 fatty acids/low in omega-6, conjugated linoleic acid (only found in pastured animals) known to reduce cancer risk, more vitamin E | bovine serum albumin can cause allergies |
| Squash | Fruit | Vitamins, minerals, can calm upset stomach | Can be high in sugars depending on type, some may quibble it's a "New World" food and would not have been available to our ancestors |
| Cumin | Spice | antioxidant, reduces blood glucose levels in diabetics, shown to have anticancer effects in some studies, animal studies show it could stimulate bile acid secretion and pancreatic enzymes | Did paleolithic people use spices? Who knows, but either way they are outside efficient foraging theory because of medicinal and flavor value. Regardless, the evidence is that cumin is harmless. |
| Wakame, kombu, hijiki, and other seaweeds | Sea Vegetable | iodine, sodium, calcium, zinc, iron, bioavailable protein | environmental contamination, too much iodine if eaten in excessive quantities, lignans (a phytoestrogen), some difficult to digest sugars |
| Coconut | Nut | High in healthy saturated fats, potassium | some people are sensitive to fructose (digestive problems) and salicylates |
| Pastured Pork | Meat | High in delicious fat, sustainable | A very small group of people is sensitive to amines, which are present in meat that is not perfectly fresh |
| Pastured Chicken | Meat | Protein, folate, tons of other vitamins and minerals | Relatively high in omega-6, very different from wild fowl |
| Grain Finished Beef | Meat | high in omega-6 fatty acids | |
| Macadamia nuts | Nut | High in monosaturated fats, low in omega-6 fats, relatively low in antinutrients compared to other nuts | |
| Poultry Eggs | Egg | Choline, protein, fats | membranolytic proteins, such as lysozyme16, that break cell membranes and may contribute to leaky gut |
| Chives and other wild and semi-wild alliums | Root | vitamin B, vitamin C and small amounts of minerals | |
| Kale | Leaf | Large amounts of vitamins, anti-cancer phytonutrients | Raffinose can cause gas, oxalates |
| Blueberries | Fruit | Vitamins | Sugar, as always, the smaller and bluer wild blueberries are healthier |
| Onions | Root | vitamin B, vitamin C and small amounts of minerals | relatively high in fructose and other fibers= can cause err...stomach problems, raw onions may disturb intestinal flora |
| Carrots (Daucus carota) | Root | High in vitamins, minerals, and antioxidants | Small amounts of oxalic acid, sugars |
| Yams | Tuber | Some anthropologists contend that tubers were a major part of the ancestral diet, Kitavans are healthy traditional diet population that relies on them, net base yielding | Others point out that they contain no essential nutrients and make no sense in terms of human evolution, starch linked to obesity and metabolic syndrome, goitrogens |
| Taro (Colocasia esculenta) | Root | Eating by the Kitavans and other healthy tropical populations, fermented taro = poi is probiotic, rich in potassium | Inedible raw, high in carbohydrates |
| Avocado | Fruit | tasty source of plant fats | New world food that evolved to attract giant sloths probably consumed first by humans 10,000 years ago, very high in omega-6, persin toxin can cause allergic reactions, tyramine can cause high blood pressure (rare), |
| Cashews | Nut | high in copper and magnesium | inedible in the wild, high in omega-6 fatty acids, oxalates present |
| Almonds | Nut | Vitamin E | High in Omega-6 fatty acids, tannins (rob body of protein), phytic acid (rob body of minerals) |
| Peppers | Fruit | Vitamins, minerals, tasty, antioxidants | Topical, mucosal, and GI irritations in sensitive individuals, solanine linked to arthritis, "New World" |
| Salt | Mineral | Some people (like me) have hypotension (seems to have a genetic factor), healthy kidneys (of person who eats the right diet, is not vitamin D deficient, exercises) should be able to deal with it | Causes hypertension in some people = strokes and heart attacks, most diets net acid producing and do not have the sort of potassium to sodium ratio our ancestors did, would have been rare in ancestral diets, linked to stomach irritation |
| Black Pepper (Piper nigrum) | Spice | Some studies show anticancer properties | Potential GI irritant, extreme amounts linked to esophageal cancer |
| Cinnamon | Spice | Shown to help diabetics lower blood sugar, antioxidant | Can be a GI and kidney irritant, many people allergic, oil is the most harsh |
| Factory Farmed Pork | Meat | Cheap | High in omega-6 fatty acids, added hormones, environmental contaminants |
Not Paleo
| Food | Type | Pros | Cons |
|---|---|---|---|
| Dairy, in general | Definitely Not Paleo | tons of nutrients, especially in raw milk, delicious, nomads who rely on it are generally pretty healthy | Large % of the population is lactose intolerant= damage to digestive system for those who are lactose intolerant, cocktail of hormones meant for growing cow, betacellulin = hormone tied to cancers, casein shown to be addictive in some studies = esp. dangerous when combined with sugar like in milk chocolate |
| Potatoes | Definitely Not Paleo | Delicious....yes, that's a legit pro! | High in carbohydrates, glycoalkaloid antinutrient can lead to leaky gut and possibly contribute to arthritis, paleolithic people would probably have eaten tubers, but not stem tubers like potatoes |
| Fermented Soy | Definitely Not Paleo | folate, vitamins, minerals, protein, sometimes probiotic | fermentation destroys some, but not all of soy's toxic compounds, can still cause stomach upset |
| Olives and Olive Oil | Definitely Not Paleo | antioxidants, tasty | high in omega-6 fatty acids, olives are only edible when pickled or made into oil, high in sodium |
| Legumes: peas, beans, peanuts, etc. | Definitely Not Paleo | Protein, vitamins, minerals, when soaked/fermented they have fewer cons | Lectins and saponins linked to leaky gut syndrome (possible cause of autoimmune issues and digestive disorders), can cause upset and inflammation of the gastrointestinal tract, high in omega-6 fatty acids that can cause inflammation and spoil easily |
| Chocolate | Definitely Not Paleo | extremely delicious to most humans, antioxidants, a few minerals | caffeine, addictive, definitely not paleo as it is a new world food and also must undergo a fermentation for consumption, may be a digestive system irritant, most chocolate contains small amounts of lead, not appetizing unless consumed with large amounts of sugars |
| Sesame Seeds | Definitely Not Paleo | iron, antioxidants | Paleolithic people would probably not have bothered/been able to gather tiny seeds like this esp. in large amts, high in omega-6 fatty acids, large amounts of antinutrient phytic acid which inhibit mineral absorption, |
| Flaxseeds | Definitely Not Paleo | omega 3 fatty acids, fiber, manganese | omega 3 fatty acids barely bioavailable by human body compared to those found in fish, high fiber can cause bloating, cyanogenic compounds in raw seeds, fats spoil quickly in ground seed, potential prostate cancer risk |
| Hemp | Definitely Not Paleo | Has some omega-3 fatty acids, protein | High in omega-6 fatty acids, prone to oxidation (spoilage) especially since ridiculous US law prohibits selling intact seeds and most products sold in the US have been sitting unrefrigerated on shelves for who knows how long |
| Unfermented Soy | Definitely Not Paleo | folate, vitamins, minerals, protein | Phytoestrogens that disrupt endocrine function and are potent antithyroid agents, pesticides used on non-organic soy, reduced bioavailablity of minerals due to phytic acid, protease inhibitors tied to cancer |
| Wheat and other gluten grains | Definitely Not Paleo | fermented grains may have fewer antinutrients, prebiotic | 1 out of 100 people is gluten intolerant (celiac) and many more may be gluten sensitive = both conditions very much underdiagnosed and can cause longterm damage and death, antinutrients like phytic acid and lectins are known to damage the gut, high in omega-3 fatty acids, other foods have more nutrients without the downsides of gluten |
