Difference Between Gluten-free and Paleo

Main Difference – Gluten-free vs Paleo

Different types of healthy dietary plans have gained a lot of attention in recent years. However, selecting dietary plans to improve health and wellbeing may sometimes be a confusing and difficult task. Gluten-free and Paleo diets are two popular dietary plans in the modern world. Many consumers still have very narrow knowledge about these dietary lifestyles and also many people incorrectly use the terms “Gluten-free” and “Paleo” interchangeably. A gluten-free diet can be defined as a diet that excludes gluten, a protein compound that originates in wheat, barley, rye etc. In contrast,  Paleo diet is gluten free, dairy free and preservative free diet and it can be more restrictive diet than regular gluten free diet. Although this is the main difference between gluten-free and paleo diets, the dietary guidelines may also differ between gluten-free and paleo diets. Therefore, it is important to identify the difference between gluten-free and paleo diets in order to select the dietary lifestyle. In this article, let’s discuss the difference between gluten-free and paleo.

What is Gluten-free Diet

A gluten-free diet is a dietary plan that eliminates a protein compound called gluten, which is mainly found in cereal grains such as wheat, barley, rye etc. Gluten is a protein that has little nutritional and biological value, and this protein is not essential to the human diet. Gluten protein can give rise to a number of health complications including coeliac disease, wheat allergy, non-coeliac gluten sensitivity, gluten ataxia and dermatitis herpetiformis. Gluten-free diets are mainly designed for these patients because these diets are demonstrated effective treatment. Furthermore, the gluten-free diet may also prevent or manage irritable bowel syndrome, rheumatoid arthritis, multiple sclerosis or HIV enteropathy. A gluten free-diet derived is mainly from naturally gluten-free foods with a proper amount of required micro and macro nutrients. Gluten-free diets usually comprise with meat, fish, eggs, legumes, nuts, fruits, vegetables, potatoes, rice, maize etc.Difference Between Gluten-free and Paleo

The paleo diet is mainly designed to improve health.

In conclusion, both gluten-free and paleo diets are two types of popular healthy dietary plans in the world. Although many people switch to a gluten-free diet out of medical requirements, some other consumers also do so simply because they think it is a healthier alternative to the modern Western diet. However, gluten-free doesn’t necessarily make them healthy because processed gluten-free foods can still be high in sugar and bad fats as well as artificial ingredients. In contrast, the paleo diet is both gluten-free and all natural and it’s a healthier option compared to gluten-free diet.
