The Mediterranean diet has been the ‘Best Diet Overall’ for seven consecutive years, according to rankings by the U.S. News & World Report. It is not a fad; it’s a way of life rooted in wholesome, healthy, and tasty food. My husband and I have fully embraced this method, and the result has been revolutionary for our cardiovascular well-being, brain function, and overall energy levels. If you’re willing to read about a diet that is as delicious as it is nutritious, the Mediterranean approach is the perfect starting point.
What distinguishes the Mediterranean diet is its focus on quality rather than restriction. While fad diets restrict whole food groups, this way of life involves indulging in meals that are high in whole foods, healthy fats, and lean protein. Main staples are:
- Vegetables and fruits
- Whole grains
- Legumes and beans
- Nuts and seeds
- Olive oil, herbs, and spices
For active lives such as ours in the United States, having the ability to source these ingredients effectively is critical. That’s where Costco is a game-changer. It offers the ability to stock quality essentials in bulk, with convenience and value bundled together in a way that makes it uncomplicated to have a Mediterranean-style kitchen without having to compromise on quality. Following is a closer look at the 14 Costco essentials that enable our Mediterranean lifestyle.
