Paleo Diet – Why Is it Popular

The paleo diet, rooted in the Stone Age or Paleolithic Era, includes foods like lean meats, fish, vegetables, nuts, and seeds. Poultry, dairy, grains, and processed foods are excluded. The diet’s premise is that our genes haven’t changed despite evolving food habits. This ancient diet is believed to maintain health better, challenging modern balanced meals.

According to health professionals recommending the paleo diet, the required nutrients can be obtained from the ‘caveman diet’, excluding modern food habits. The ‘Discordance Hypothesis’ highlights that modern diets conflict with our genes, contributing to obesity, cardiovascular diseases, hypertension, and diabetes. One of the notable facts about the paleo diet is that it doesn’t prescribe a calorie count, setting it apart from most diets. It encourages physical activity and adequate water intake for stability. Despite controversies, it can be beneficial for significant weight loss. Know some facts about weight loss surgery and its limitations.

Paleo Diet Food List

The paleo diet, also known as the paleolithic or caveman diet, focuses on consuming foods that our hunter-gatherer ancestors would have eaten. It promotes unprocessed foods that are rich in nutrients and excludes processed items and grains. It involves foods reflecting paleolithic eating, like some of the following.

  • Meat: Lean meats like beef, lamb, pork, and poultry.
  • Fish and Seafood: Fatty fish (salmon, mackerel) for omega-3s, plus shellfish.
  • Eggs: A protein and healthy fat source.
  • Fruits: All types, but consume in moderation.
  • Vegetables: Non-starchy variety in different colors.
  • Nuts and Seeds: Almonds, walnuts, pumpkin seeds, etc., in moderation.
  • Healthy Fats and Oils: Olive oil, coconut oil, avocado oil.
  • Herbs and Spices: Flavor enhancers like garlic, ginger, turmeric.
  • Natural Sweeteners: Limited use of honey, and maple syrup.
  • Beverages: Water, herbal tea, black coffee, coconut water in moderation.

Avoid grains, legumes, dairy, refined sugar, processed foods, vegetable oils, and additives.

What Is the Main Idea of the Paleo Diet?

Our ancestors, thousands of years ago, were involved in hunting, fishing, and gathering food. Many years later, people started farming. They got involved in agriculture and grew their grains. However, the main idea of the paleo diet is that our genes are not adapted to the consumption of products that were obtained as a result of farming/agriculture. Since we have the same genes as our ancestors, it would be wise for us to eat exactly what they consumed thousands of years ago.

Paleo Diet - Same Food as that of Our Ancestors

Therefore, we cannot eat the grains, legumes, dairy products, etc., that are obtained from farming because our genes are not tuned to these types of food items. So, it would make sense if we consume the same fruits, vegetables, fish, eggs, and nuts that our ancestors gathered and ate.

The paleo diet’s focus on whole, unprocessed foods may also reduce inflammation and support digestive health. Many short-term studies suggest that the paleo diet helps maintain cholesterol and triglyceride levels. Switching over from other types of fatty meat to lean meat is better for health because lean meat contains more protein and less fat than the other types. Skinless chicken is an example of lean meat. Fish like salmon and other seafood are also included in the paleo diet. Here’s what you must know about salmon

Pros and Cons of the Paleo Diet

The paleo diet is a highly controversial one. While some people regard it as the perfect diet, others beg to differ. Some of the pros and cons of the diet are described below.


1. Rich in Protein   

The seeds, nuts, and lean meat have excellent protein content, which is crucial for the muscles, bones, and skin. Protein also helps maintain a healthy body composition. Do you know if you must have protein before or after a workout?

2. Unsaturated Fats

The unsaturated fats present in nuts, olive oil, and avocados are beneficial for health because they assist in maintaining a healthy lipid profile.

3. Rich in Potassium

Potassium is essential for the proper functioning of the kidneys. It also regulates blood pressure. Potassium is found in fruits and vegetables, which form a large part of the paleo diet.


1. Deficiency in Some Nutrients

The paleo diet excludes many food items, such as dairy products, which are fabulous sources of calcium and other nutrients. So, these nutrients are not made available for people following the diet. Calcium deficiency can result in lower bone density. Lack of calcium even leads to tooth problems.

2. Evolution of Humans

The diet revolves around the fact that we have the same genes as our hunter-gatherer ancestors. However, the fact that humans have evolved over thousands of years is not taken into account. We have not only evolved, but our digestive systems have also become adapted to the changing environment. While our ancestors, from over 10,000 years ago, would have had a highly active life running about and hunting animals for food, people are currently more adapted to an inactive life. So, we cannot take the same fatty diet that our ancestors have consumed. 

3. Legumes Are Not Included

Legumes are rich in magnesium, manganese, and selenium. Legumes are extremely important for gut health. But the paleo diet excludes legumes. So, humans might miss out on the gut health benefits.You have now seen the pros and cons of paleo diet. While some studies involving small groups of people state that the paleo diet is best for humans, a lot more research is necessary to confirm this theory.

Is the Paleo Diet Better than Other Diets?

Interesting Facts About Paleo Diet

In the opinion of many, eating like our cavemen actually aligns with our genetics. However, over the years, people started consuming the products of agriculture, which has led to many chronic diseases, including allergies and obesity. So, eating what humans consumed in the Stone Age can prevent chronic diseases and maintain health. Avoiding refined sugar and processed foods reduces the risk factors for many diseases. So, for people following the paleo diet, the benefits of paleo diet outnumber the demerits. 

On the other hand, consuming mostly animal products can increase the intake of cholesterol, especially the ones that are less healthy. In the long run, this dietary practice can result in increased risks of heart disease. Thus, we cannot say that the paleo diet is better than other diets. Long-term consumption of large portions of animal products can affect health in many other ways too. Do you know the effects of consuming too much meat? And, the paleo diet works for some but not for others. Avoiding dairy products may result in osteoporosis because the body is devoid of calcium and Vitamin D.

Bottom Line: 
The bottom line is that the paleo diet is always not better than other diets. It could be beneficial for some for a period of time, but not for everyone at all times.
