Foods to Avoid on a Paleo Diet: A Guide to Eating Like Our Ancestors

Posted on

Foods to avoid on paleo diet – The paleo diet is a popular eating plan that mimics the diet of our hunter-gatherer ancestors. It emphasizes whole, unprocessed foods that were available during the Paleolithic era, and it eliminates grains, legumes, dairy, sugar, and processed foods. In this article, we’ll explore the foods to avoid on a paleo diet and why they’re not recommended.

The paleo diet is based on the idea that our bodies are not adapted to the modern diet, which is high in processed foods, sugar, and unhealthy fats. By eating like our ancestors, we can improve our health and reduce our risk of chronic diseases such as heart disease, obesity, and diabetes.


Grains are a major part of the modern diet, but they are not a part of the paleo diet. This is because grains were not a significant part of the human diet until the advent of agriculture, which began about 10,000 years ago.

Before that, humans were hunter-gatherers, and their diet consisted of meat, fish, fruits, vegetables, and nuts.

There are several reasons why grains are avoided on a paleo diet. First, grains contain gluten, which is a protein that can be difficult to digest. Gluten can cause inflammation in the gut, and it can also lead to a number of health problems, such as celiac disease and gluten intolerance.

Second, grains are high in carbohydrates, which can lead to weight gain and other health problems. Third, grains are often processed, which means that they have been stripped of their nutrients and fiber.

Common Grains to Avoid

  • Wheat
  • Rice
  • Corn
  • Barley
  • Rye
  • Oats

Potential Health Benefits of Eliminating Grains

  • Weight loss
  • Reduced inflammation
  • Improved digestion
  • Lower risk of chronic diseases, such as heart disease and diabetes


Legumes, including beans, lentils, and peanuts, are not allowed on the paleo diet. Legumes are a good source of protein, fiber, and vitamins, but they also contain lectins and phytates, which can interfere with digestion and absorption of nutrients. Additionally, legumes contain carbohydrates that can spike blood sugar levels, which is not ideal for people following a paleo diet.

Alternative Protein Sources

There are several alternative sources of protein for people following a paleo diet, including:

  • Meat
  • Fish
  • Eggs
  • Nuts and seeds
  • Bone broth

Dairy: Foods To Avoid On Paleo Diet

Dairy products, such as milk, cheese, and yogurt, are a staple in many modern diets. However, on a paleo diet, dairy is strictly prohibited. This is because dairy products are believed to be inflammatory and contribute to a variety of health problems, such as acne, bloating, and digestive issues.

Dairy Products to Avoid

  • Milk
  • Cheese
  • Yogurt
  • Ice cream
  • Butter
  • Sour cream
  • Whey protein

Health Benefits of Removing Dairy

Eliminating dairy from your diet can have a number of health benefits, including:

  • Reduced inflammation
  • Improved digestion
  • Clearer skin
  • Reduced risk of chronic diseases, such as heart disease and cancer

Nutritional Comparison

The table below compares the nutritional content of dairy products to that of plant-based alternatives:| Nutrient | Dairy Products | Plant-Based Alternatives ||—|—|—|| Protein | 8g per cup | 7g per cup || Calcium | 300mg per cup | 300mg per cup || Vitamin D | 125IU per cup | 125IU per cup || Fat | 8g per cup | 2g per cup || Cholesterol | 30mg per cup | 0mg per cup |

If you’re following the paleo diet, you’ll want to avoid grains, legumes, dairy, and processed foods. But what about when you’re eating out? Check out this guide to eating out on the hcg diet for some tips on how to make healthy choices while dining out.

Call to Action

Artificial sweeteners may seem like a tempting way to satisfy your sweet tooth without the calories, but their potential health risks make them a wise choice to avoid. Opt for natural alternatives instead to maintain optimal health and well-being.

Vegetable Oils

Vegetable oils are a staple in many modern diets, but not all vegetable oils are created equal. Some vegetable oils are high in omega-6 fatty acids, which can be harmful to health when consumed in excess.

Omega-6 fatty acids are essential fatty acids that the body cannot produce on its own. They must be obtained from the diet. However, too much omega-6 can lead to inflammation and other health problems.

Allowed Vegetable Oils

  • Olive oil
  • Avocado oil
  • Coconut oil
  • Macadamia nut oil

These oils are low in omega-6 fatty acids and high in omega-3 fatty acids, which are beneficial for health.

Non-Allowed Vegetable Oils

  • Soybean oil
  • Corn oil
  • Canola oil
  • Sunflower oil

These oils are high in omega-6 fatty acids and should be avoided on a paleo diet.

Healthier Alternatives to Vegetable Oils

  • Use olive oil or avocado oil for cooking and salad dressings.
  • Use coconut oil for baking and frying.
  • Use macadamia nut oil for salad dressings and dips.

These healthier alternatives are lower in omega-6 fatty acids and higher in omega-3 fatty acids, which are beneficial for health.

Table: Allowed vs. Non-Allowed Vegetable Oils

Allowed Vegetable Oils Non-Allowed Vegetable Oils
Low in omega-6 fatty acids High in omega-6 fatty acids
High in omega-3 fatty acids Low in omega-3 fatty acids
Beneficial for health Harmful to health when consumed in excess

Impact of Omega-6 Fatty Acids on the Body

Omega-6 fatty acids are essential fatty acids, but too much omega-6 can lead to inflammation and other health problems. Inflammation is a major risk factor for many chronic diseases, including heart disease, stroke, cancer, and Alzheimer’s disease.

The paleo diet is designed to reduce inflammation by limiting the intake of omega-6 fatty acids and increasing the intake of omega-3 fatty acids. Omega-3 fatty acids are anti-inflammatory and have been shown to protect against a variety of chronic diseases.

Trans Fats

Trans fats are a type of unsaturated fat that is created when liquid oils are turned into solid fats, a process called hydrogenation. Trans fats are not naturally occurring and are considered unhealthy because they can raise LDL (bad) cholesterol and lower HDL (good) cholesterol, increasing the risk of heart disease.

Foods to avoid on the paleo diet include grains, legumes, dairy, processed foods, and sugar. These foods can cause inflammation and other health problems. After the HCG diet, it’s important to continue avoiding these foods to maintain your weight loss and improve your overall health.

Life after the HCG diet can be challenging, but by avoiding these foods, you can set yourself up for success.

Foods that contain trans fats include margarine, fried foods, processed snacks, and baked goods. Trans fats can also be found in small amounts in some animal products, such as meat and dairy.

Potential Health Risks

Consuming trans fats has been linked to an increased risk of heart disease, stroke, type 2 diabetes, and obesity. Trans fats can also contribute to inflammation and oxidative stress, which are both linked to chronic diseases.

Sticking to the paleo diet means cutting out grains, dairy, and processed foods. These foods can trigger inflammation, which can worsen rheumatoid arthritis symptoms. An anti-inflammatory diet for rheumatoid arthritis can help reduce inflammation and improve symptoms. This diet includes eating plenty of fruits, vegetables, and whole grains.

It also includes avoiding foods that are known to trigger inflammation, such as sugar, processed foods, and red meat. For more information on an anti-inflammatory diet for rheumatoid arthritis, visit anti inflammatory diet for rheumatoid arthritis .

Provide examples of non-alcoholic beverages that can be enjoyed on a paleo diet.

The paleo diet emphasizes consuming whole, unprocessed foods similar to what our ancestors ate during the Paleolithic era. While alcoholic beverages are not part of the traditional paleo diet, there are several non-alcoholic options that can be enjoyed.

Some examples of paleo-friendly non-alcoholic beverages include:

  • Water:The most natural and hydrating beverage, essential for overall health.
  • Unsweetened tea:Green tea, black tea, and herbal teas provide antioxidants and other health benefits.
  • Sparkling water:A refreshing and hydrating alternative to soda, without added sugars or artificial sweeteners.
  • Coconut water:A naturally sweet and hydrating beverage rich in electrolytes.
  • li> Fruit-infused water:Adding slices of fresh fruit to water enhances flavor and provides additional nutrients.


Nightshades, a family of plants that includes tomatoes, potatoes, eggplants, and peppers, have been a subject of debate in the paleo community. Some proponents of the paleo diet believe that nightshades contain harmful compounds that can trigger inflammation and other health issues.

Potential Health Concerns

Nightshades contain alkaloids called solanine and chaconine, which are natural toxins that can cause gastrointestinal distress, inflammation, and joint pain in some individuals. These alkaloids are particularly concentrated in the leaves and stems of nightshades, but they can also be found in the fruits and vegetables.

Tips for Avoiding Nightshades

If you experience any adverse reactions to nightshades, it’s best to avoid them. Here are some tips:* Read food labels carefully to identify hidden sources of nightshades.

  • Soy sauce
  • Edamame
  • Tofu
  • Tempeh
  • Miso
  • Soy flour
  • Soy protein isolate
  • Soy lecithin
  • Soy oil

If you’re unsure whether a food contains soy, it’s best to err on the side of caution and avoid it.


Corn, a staple in many modern diets, is not permitted on the paleo diet. This is primarily due to its classification as a grain, a food group excluded from the paleo approach.

Beyond its grain status, corn also raises concerns related to its potential impact on health. One of the primary issues with corn is its high glycemic index, which can lead to spikes in blood sugar levels and insulin resistance. Additionally, corn often contains high levels of lectins, proteins that can interfere with nutrient absorption and potentially contribute to inflammation in the gut.

Identifying and Avoiding Corn

Identifying and avoiding corn-containing foods can be challenging, as it is a common ingredient in a wide range of processed foods. Some common sources of corn include:

  • Corn syrup
  • Cornstarch
  • Cornmeal
  • Polenta
  • Corn flakes
  • Corn tortillas
  • Popcorn

To avoid corn, carefully read food labels and look for these ingredients. Additionally, be aware that corn may be hidden in other ingredients, such as “natural flavors” or “vegetable gums.” If you are unsure whether a food contains corn, it is best to avoid it.


Peanuts are a common food allergen and should be avoided on a paleo diet due to their potential health concerns. Peanuts are legumes and not actually nuts, and they contain a protein that can trigger allergic reactions in some individuals.

Potential Health Concerns Associated with Peanut Consumption

  • Allergies:Peanut allergies are one of the most common food allergies, affecting approximately 1% of the population. Symptoms of a peanut allergy can range from mild, such as hives or itching, to severe, such as anaphylaxis.
  • Inflammation:Peanuts contain a compound called arachidonic acid, which can promote inflammation in the body. Inflammation has been linked to a number of chronic diseases, including heart disease, cancer, and arthritis.
  • Nutrient deficiencies:Peanuts are high in phytates, which can bind to minerals and prevent their absorption. This can lead to nutrient deficiencies, such as iron deficiency anemia.

Tips for Avoiding Peanuts

  • Read food labels carefully:Peanuts and peanut oil are common ingredients in many processed foods, including granola bars, trail mix, and peanut butter cups.
  • Be aware of hidden sources of peanuts:Peanuts can also be found in unexpected places, such as sauces, marinades, and even some cosmetics.
  • Ask questions when eating out:If you are unsure whether a dish contains peanuts, don’t hesitate to ask your server or the chef.

Alternative Snacks and Food Sources

There are many delicious and nutritious snacks and food sources that can replace peanuts in a paleo diet. Some good options include:

  • Nuts (almonds, walnuts, pecans, cashews)
  • Seeds (pumpkin seeds, sunflower seeds, chia seeds)
  • Fruit (apples, bananas, berries)
  • Vegetables (carrots, celery, cucumbers)

Added Salt

Excessive salt intake is discouraged on the paleo diet due to its potential negative health implications. High sodium consumption can lead to fluid retention, which can strain the heart and blood vessels, potentially contributing to high blood pressure and heart disease.

It can also increase the risk of stroke, kidney stones, and stomach cancer.

Tips for Reducing Salt Intake, Foods to avoid on paleo diet

To minimize salt intake while following a paleo diet, consider these tips:

  • Avoid processed foods:These foods often contain high levels of added salt.
  • Cook meals from scratch:This allows you to control the amount of salt added.
