What Foods You Can (and Can’t) Eat on the Paleo Diet
Uncover simple swaps and approved ingredients for balanced, nutrient-rich meals.
The Paleo diet champions eating patterns based on what prehistoric humans might have consumed, focusing on whole, minimally processed foods. Modern interpretations emphasize high protein intake, healthy fats, high fiber from produce, and the exclusion of processed items, grains, legumes, and dairy. Understanding which foods are allowed or forbidden—and the nutritional reasons behind these choices—is essential for anyone considering a Paleo regimen.
Introduction to the Paleo Diet
The Paleo diet encourages the consumption of foods presumed to be available to early humans through hunting and gathering. The underlying goal is improved health by favoring whole foods and avoiding highly processed or agricultural products introduced in the modern era.
Core Principles:
- Eat lean meats, fish, fruits, vegetables, nuts, and seeds.
- Avoid processed foods, grains, legumes, and most dairy.
- Emphasize fiber, healthy fats, and naturally nutrient-rich foods.
The premise is that such foods align better with human evolution, potentially leading to better energy levels, improved digestion, and reduced chronic disease risk.
Note: There are multiple Paleo variations, and some plans permit limited exceptions (such as grass-fed butter or certain root vegetables).
Benefits of the Paleo Diet: Whole Foods for Better Health
Nutrition experts spotlight a few key benefits to following Paleo guidelines:
- Increased whole food intake: You naturally cut down on processed snacks and preservatives.
- Higher protein consumption: Lean meats and fish are staples.
- Rich nutrient profile: Fruits, vegetables, nuts, and seeds supply key vitamins and antioxidants.
- Fewer artificial ingredients and hidden sugars: The diet’s rules eliminate many sources of excess sugar and sodium.
However, the diet’s restrictive nature means you need to thoughtfully replace nutrients found in omitted food groups. Many experts advise careful planning to avoid pitfalls such as low fiber intake or inadequate calcium, especially if you exclude fortified foods and most dairy.
Paleo Nutrition Concerns and Practical Advice
Adhering strictly to Paleo rules means cutting out entire food groups—most notably grains, legumes, and dairy. This can create certain nutritional gaps:
- Fiber: Whole grains and legumes are major fiber sources for most people. Increase intake of fiber-rich fruits and vegetables to compensate.
- Calcium: Excluding dairy can lead to insufficient calcium intake. Seek fortified nut milks (such as almond or coconut milk, but check labels closely), fish, and green vegetables for calcium.
- Calories: Some people may not eat enough total calories if they do not plan meals carefully; include energy-dense, nutrient-rich options.
What others are reading
Tip: If supplementing is necessary (especially for calcium), consult with a healthcare provider and choose natural, whole food sources whenever possible.
Why Are Certain Foods Forbidden?
Several food groups are off-limits primarily because:
- They were not widely available before agriculture.
- They can be sources of processed sugars, anti-nutrients, or allergens.
- Paleo theory posits they may contribute to inflammation or chronic disease.
This includes grains, legumes, dairy, processed foods, and certain sweeteners.
Are ‘Paleo Sweets’ Healthier?
Refined sugars are forbidden, but natural sweeteners like honey, maple syrup, and agave are often allowed on Paleo. Experts warn that sugar is sugar—these alternatives are not inherently healthier when consumed in excess. Use sparingly, focusing on whole fruits and unrefined sources whenever possible.
What You Can Eat on the Paleo Diet
The Paleo shopping list includes a variety of proteins, produce, healthy fats, nuts, seeds, and natural sweeteners. Strategic swaps—such as choosing almond flour over wheat flour—can help make favorite dishes Paleo-friendly.
| Food Category | Examples |

| Lean meats (prefer grass-fed/wild) | Chicken, beef, pork, turkey, bison, venison |
| Fatty fish & seafood | Salmon, mackerel, albacore tuna, crab, clams, oysters, lobster, mussels |
| Eggs | Cage-free or organic preferred |
| Flour alternatives | Almond flour, coconut flour, cassava flour |
| Healthy fats & oils | Olive oil, avocado oil, walnut oil, macadamia nut oil, flaxseed oil, coconut oil |
| Butter (in some plans) | Grass-fed butter or ghee |
| Non-starchy vegetables | Brussels sprouts, broccoli, cauliflower, spinach, cabbage, butternut squash |
| Nuts & seeds | Almonds, cashews, walnuts, macadamia, pecans, hazelnuts, pine nuts, pumpkin seeds, chia, sunflower, flax |

| Herbs & spices | All varieties (fresh or dried) |
Shopping Tips:
- Choose grass-fed or wild-caught animal proteins when possible for higher omega-3s.
- Try almond/coconut flour for baking and breads.
- Check nut milks for calcium fortification (many organic or natural brands may not be fortified).
- Select unsweetened, natural nut butters; avoid added sugars or oils.
What You Can’t Eat on the Paleo Diet
The following are generally forbidden or highly restricted in a true Paleo plan:
- Grains: Wheat, oats, barley, rye, rice, corn.
- Legumes: Beans, lentils, peanuts.
- Dairy Products: Milk, cheese, yogurt, ice cream (some allow small amounts of grass-fed butter).
- Refined sugars: Table sugar, high fructose corn syrup.
- Processed foods: Chips, crackers, cookies, baked goods, cereals, instant meals.
- Salt: Added salts in prepared foods or as seasoning.
- Starchy vegetables: White potatoes, corn, peas, jicama (exceptions for some root vegetables in some versions, like sweet potatoes).
- Artificial sweeteners: Aspartame, sucralose, saccharin.
- Trans fats & hydrogenated oils: Margarine, shortening.
Dishes made with forbidden ingredients—including breads, pasta, chips, cakes, and most packaged snacks—are not part of Paleo eating.
Paleo Food Substitutes and Swaps
Adopting Paleo doesn’t mean losing favorite flavors or dishes—just make smart substitutions:
- Almond/coconut/cassava flour for wheat flour in recipes.
- Spiralized zucchini, sweet potatoes or cauliflower as pasta/rice substitutes.
- Nut milks (fortified) instead of dairy.
- Natural sweeteners like raw honey or maple syrup in place of refined sugars (sparingly).
- Avocado, olive oil, or ghee as cooking fats instead of margarine or vegetable oils.
Paleo Diet Sample Day Menu

Frequently Asked Questions (FAQs)
Q: Can I have coffee on Paleo?
A: Strict Paleo excludes coffee, but some modern iterations allow decaf or black coffee, ideally unprocessed and without creamers.
Q: How can I get enough calcium without dairy?
A: Focus on fortified nut milks (check labels), green vegetables (broccoli, spinach, Brussels sprouts), nuts and seeds, and fish (especially with edible bones, like sardines). Supplements may be needed in some cases; consult your nutritionist.
Q: Are sweet potatoes Paleo?
A: Some plans do allow sweet potatoes, seeing them as less starchy and more nutrient-rich than white potatoes, but their inclusion varies. Check your plan’s guidelines.
Q: Why are legumes forbidden?
A: Legumes are excluded due to their “anti-nutrient” content (like phytic acid) and their association with post-agricultural diets. Paleo advocates believe avoiding them best matches prehistoric eating.
Q: Can I use grass-fed butter or ghee?
A: Some flexible Paleo approaches approve grass-fed butter or ghee in small amounts. Purists exclude all dairy, but many allow these forms due to minimal processing and possible health benefits.
Final Tips for Starting the Paleo Diet
- Start by removing processed foods from your pantry.
- Plan meals for adequate calories and nutrient density—especially focus on fiber and calcium sources.
- Make smart swaps to fill gaps and diversify your food intake.
- Read ingredient labels—fortified nut milks and natural nut butters vary widely in content.
- Treat “Paleo sweets” and honey like regular sweets; moderation is key.
- Consult a healthcare professional before supplementing, especially if you have specific dietary needs or restrictions.
