Mediterranean diet: What you need to know
May is Mediterranean Diet Month, according to the American Diabetes Association’s Facebook page.
The diet, with its high intakes of cereals, extra-virgin olive oil, fruits, leafy green vegetables, nuts and pulses/legumes, moderate intakes of dairy products, fish and other meats, and red wine, and low intakes of eggs and sweets, was first defined approximately 50 years ago by Ancel Keys, PhD, a physiologist who taught at the University of Minnesota, according to an article in Nutrients.
In the decades since, a plethora of research has examined the effect the Mediterranean diet has on one’s health.
Amy Riolo, author of the ADA’s recent cookbook on the food plan, told Healio Primary Care pointed out a few basics that she said “need to be understood” before clinicians advise their patients on the Mediterranean diet or any food plan.
“Food is treated as medicine, moderation is key and an active physical and social lifestyle is mandatory,” she said.
Riolo also sought to clear up some misconceptions that some primary care physicians may have about the Mediterranean diet.
“When many doctors ‘prescribe’ the diet to their patients they tell them what to eat, but they do not give tips on making communal activities fit into your busy lifestyle, such as the right kinds of exercise, the importance of community and getting outdoors,” she said in the interview.
“If people enjoy the lifestyle first, the diet becomes second nature and very easy to live by naturally. It is only when we focus on the food alone that it seems like a lot of work or hard to do,” Riolo continued.
