The paleo diet is meant to mimic what our hunter-gatherer ancestors ate. But what foods should you eat to follow this diet and what foods do you want to avoid? If you're new to the paleo diet, knowing what to eat for breakfast, lunch and dinner can be hard. As with most diets, there are foods that are allowed and not allowed. Some foods also fall into a bit of a grey area and are sometimes allowed.
Our ultimate list of paleo-approved foods will help simplify your planning if you're dining out or cooking at home. Whether you're a beginner or just looking for a refresher on the rules, here's what you need to know to eat paleo.

What is the Paleo Diet?

The premise behind "eating paleo" is that the current Western diet is contributing to the rise of chronic diseases such as obesity, heart disease and cancer. Paleo diet proponents claim, eating this way can reduce inflammation, improve workouts, increase energy, help with weight loss, stabilize blood sugar and even reduce the risk of chronic diseases.
The pros of paleo are that it focuses on increasing intake of whole foods, fruits and vegetables, lean proteins and healthy fats and decreasing consumption of processed foods, sugar and salt. For those looking to eat a more well-rounded diet, these "guidelines" sound familiar and altogether healthy.
However, the paleo diet also advocates cutting out grains, dairy and legumes, and this has caused controversy among scientists. These foods, despite what paleo advocates claim, are healthful and can be good sources of fiber, vitamins and minerals.Read More: Healthy Paleo Recipes
Foods You Can Eat on the Paleo Diet
In short, if your ancestors could hunt or gather it, it is allowed on the paleo diet. This includes:
Grass-fed meat: choosing grass-fed is healthier for you, the environment and closer to what our ancestors ate.
Fish and seafood: choose wild-caught
Fresh fruits and veggies
Nuts and seeds
Healthy oils (olive, walnut, flaxseed, macadamia, avocado, coconut)
Meat & Seafood

Most meat and seafood fits on a paleo diet. Meat is a source of lean protein, and protein is the building block of all cells and tissues. Protein also helps keep you full. Watch out for pre-marinated meats that may contain added sugar. Common meat and seafood choices include:
Paleo Meat & Seafood
Grass-fed meat is recommended on the paleo diet because it is leaner than meat from grain-fed animals and has more omega-3 fatty acids, the healthy fats that reduce inflammation in the body and protect your heart. A typical American diet is high in saturated and trans fats and lower in healthy poly- and monounsaturated fats, hence the paleo diet's emphasis on grass-fed meats.
Look for chicken raised without antibiotics and try to source your meat from a local farm to learn more about how it was raised.
Choosing wild seafood over farm-caught may help boost your omega-3 intake too. That's not always the case, but look for wild salmon and other sustainably-caught seafood when you're eating paleo.
Fruits & Vegetables

There is little argument over the health benefits of fruits and vegetables. They are chock-full of vitamins, minerals, fiber and antioxidants. The only caveat for paleo dieters is that some vegetables are starchy (e.g., potatoes) and some fruits are higher in sugar (e.g., bananas). So, if you are trying to lose weight or watch your blood sugar levels, eat these in moderation. In fact, potatoes are banned from some strict versions of the diet.
Many paleo followers wonder if bananas are paleo, because of their higher sugar content. They are considered paleo. One medium banana has 100 calories, 3 grams of fiber and 25 grams of carbohydrate. Bananas are a good source of potassium and they are an unprocessed, whole food.
The key to remember with eating paleo is that you want your diet to contain unprocessed, whole foods so fruits and vegetables should make up a bulk of your diet. Frozen vegetables without added sauce, are also allowed on a paleo diet.
Examples of produce to eat on a paleo diet:
- Brussels sprouts
- Sweet potatoes
- Butternut squash
- Berries: including blackberries, blueberries and strawberries
- Citrus fruits
Eggs are allowed because they are high in protein, B vitamins, minerals and antioxidants. They are also affordable and easy to prepare. Buy "organic" and "cage-free" eggs for a higher omega-3 content than eggs from chickens raised in cages.
Nuts & Seeds

Nuts and seeds are full of healthy fats, fiber and protein. Plus, they were foraged in prehistoric times, so you can load up your cart with them. Keep in mind that peanuts are not considered paleo because they are technically legumes.
Paleo Nuts & Seeds
- Macadamia nuts
- Pine nuts
- Brazil nuts
- Pumpkin seeds (pepitas)
- Chia seeds
- Sunflower seeds
- Flax seeds

Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.
- Olive oil
- Walnut oil
- Flaxseed oil
- Macadamia oil
- Avocado oil
- Coconut oil

Foods You Should Avoid on the Paleo Diet
If you are following a strict paleo diet, you should avoid the following foods. These foods are not permitted on the paleo diet:
- Cereal grains
- Legumes (peanuts, beans, lentils, tofu)
- Refined sugar
- Processed foods
- Soda & sweetened beverages
- Refined vegetable oils
- Artificial sweeteners
Say goodbye to cereal, crackers, rice, pasta, bread and beer. Yes, beer. All grains are forbidden on the paleo diet. Why? First, grains are a product of modern agriculture; cavemen didn't nosh on bread. Second, grains are high in carbohydrates, which can spike your blood sugar.
Paleo critics point out that not all grains are created equal—whole grains do not spike your blood sugar as much as refined grains. Even so, paleo dieters still steer clear of grains because they contain different compounds and proteins like gluten, lectins and phytates, which they claim cause inflammation in the body and block other nutrients from being absorbed. Paleo critics say these compounds are not a problem unless you have an allergy or sensitivity.

Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soy foods, and peanuts. This also includes peanut butter and soy sauce. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.
Processed foods are full of the rest of the no-no's on the paleo diet: refined sugars, salt, refined vegetable oils and artificial sweeteners. Our ancestors didn't eat these foods. Plus, there is little argument in the scientific community that refined sugars and excess salt contribute to obesity, high blood pressure and heart disease.
There is some disagreement, however, over vegetable oils and artificial sweeteners. The American Heart Association recommends consuming corn, safflower and canola oils, but paleo plans say these are "not allowed" because of the ratio of omega-6 to omega-3 fatty acids and the way the oils are processed.
The U.S. Food and Drug Administration (FDA) condones artificial sweeteners as safe to consume, but they are not allowed on paleo since they are a man-made, processed food. Plus, although artificial sweeteners lower calories in food, research shows they can still cause us to crave sweets and that they can be harmful to our gut bacteria.

Foods You Can Sometimes Eat on the Paleo Diet
Featured Recipe: Ricotta & Yogurt Parfait
A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows. This includes milk, butter, yogurt, sour cream, and cheese. However, some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products like kefir are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy. If you prefer to avoid dairy on the paleo diet, you can substitute non-dairy products made with coconut milk, almond milk, and cashew milk.
Starchy Vegetables & High-Sugar Fruits
This is a gray area. Sugary fruits and starchy vegetables (potatoes, squash, beets) can spike your blood sugar more than berries and spinach. That's why these are OK in moderation and are best to minimize if you are trying to lose weight, according to paleo experts.
Alcohol is a no-no if you are strict paleo. Beer is made from grains, and liquor also contains traces of gluten. But, good news for cider-lovers: most hard ciders are gluten-free, so they are allowed. Check the label to be sure. Red wine is more accepted in the paleo community because it contains the antioxidant resveratrol, but sorry chardonnay lovers, white wine is technically not allowed.

How to Make the Paleo Diet Fit Your Lifestyle
This is a brief guide to following the paleo diet, but EatingWell doesn't believe in being so restrictive. Eating some of the "no" foods like whole grains, dairy and legumes is necessary to add important nutrients to your diet.
If you're interested in the paleo diet plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
