The Mediterranean diet has been named the best overall diet for the fifth year in a row by the editors of U.S. News & World Report.
The Mediterranean diet is one of the most studied diets, and one of the few diets — most of which involve higher fat or lower carbohydrate intake — that demonstrates CVD benefits, according to a U.S. News & World Report press release.

The Mediterranean diet also ranked first in the categories of best diets for healthy eating, easiest diets to follow, best diets for diabetes and best plant-based diets; it tied with best heart-healthy diets for the No. 1 spot.
A panel of 27 experts rated 40 diets in seven categories, including ease of following the plan, its ability to produce short- and long-term weight loss, “nutritional completeness,” safety and potential for preventing diabetes and CVD. The scores enabled the U.S. News & World Report health team to rate diets from one to five (five being the highest score). The cost of a plan or amount of exercise the plan requires were not part of the decision-making process, according to the press release.
“The Mediterranean diet has a lot of what we look for in healthy eating, like lean proteins, whole grains and fruits and vegetables. Overall, the reason why it ends up coming out on top is because it is really not a diet. It is more a lifestyle of eating,” said Fatima Cody Stanford, MD, MPH, MPA, MBA, FAAP, FACP, FAHA, FAMWA, FTOS, a Healio Primary Care Peer Perspective Board Member and one of the U.S. News & World Report panelists.
There are some caveats to the Mediterranean diet, Stanford told Healio.
“The diet is Eurocentric. The constant emphasis on this diet supports the notion that diets that are derived elsewhere are inferior,” she said. “This diet may also be prohibitive, particularly for those with lower socioeconomic status.”
Stanford, who is also a clinician at Harvard Medical School and Massachusetts General Hospital, noted that she did not rank the Atkins, HMR or OPTAVIA diets very high “since they have a potential for containing highly processed foods and are not as sustainable as the Mediterranean, Dash or Flexitarian.”

The U.S. News & World Report article about best diets is a useful guide for consumers, but the reader should be aware of the nuances of such guidance. The guide was based on a detailed survey of a panel of health care practitioners, health writers and people in the media, and some of the top scientists in the field of nutrition. The scientists are certain to understand the science behind nutrition, and the rankings are consistent with current scientific consensuses. Even so, it is important to remember to note that the members of any such panel bring their own personal and scientific biases to this kind of ranking process.
A lot of medical news tends to sound definitive, when in fact, the science is ever-evolving, or misunderstood or inadvertently misrepresented in the reporting. Further, when the medical community changes its recommendations, it has a real negative effect on how people view the credibility of science. Moreover, all of us, scientists, clinicians and writers alike, are subject to the pressures inherent in what we do. If science doesn’t have the answer, am I going to provide an opinion that sounds credible so that you keep asking me what to do? As has been demonstrated in the last 2 years during the COVID-19 pandemic, scientific credibility is at a low enough point that it has been easily politicized, likely resulting in a large number of unnecessary deaths in the pandemic.
It is crucial that the public be better educated on where recommendations are vulnerable to change, which are subject to variability and why. The U.S. News & World Report article is a good start, since the writers have been transparent with their methods and the makeup of the panel, but only if the reader reviews these and strives to understand the nuances.
