With the many different variations names and meanings of diets today, it is very easy to become confused! What are the rules of the flexitarian diet? What´s the difference between the Paleo and Keto diet? What are the health benefits of a dairy free diet? And what on Earth is the Macrobiotic diet??

Don’t panic! We are here to help you get up to date with the World of Nutrition! La Española has compiled a fantastic guide to the most popular food trends and diets today. There are so many delicious and nutritious diets we decided to split the dictionary in two parts! Below we have listed 10 of the 23 diets! Stay tuned for part II with the remaining 13!  

Disclaimer: Aside from the healthy, safe and universally-applauded Mediterranean diet we love, La Española does not support or condone any one diet or lifestyle choice and does not claim to have any scientific research backing many of the following diets. We encourage our readers to do their own research and consult a medical professional before embarking on a new diet plan.

What it is: A diet and lifestyle that abstains from the consumption (or use, in many cases) of animal products. Many refer to veganism as a form of “plant-based diet”.
