The Mediterranean diet has long been lauded as the world’s healthiest eating plan.

The diet, which emphasizes lean protein, seafood, and healthy fats like olive oil, has mountains of studies pointing to its benefits. 

These include weight loss, lowered risk of heart disease, and even warding off dementia. 

However, a new study suggests that an up-and-coming diet could dethrone Mediterranean plan and halve the risk of metabolic syndrome, which can lead diabetes, high blood prssure, and heart disease.

Those who stuck to the Atlantic diet instead of their normal foods for six months ‘significantly reduced the incidence of metabolic syndrome,’ including improvements in waist circumference, weight, and HDL (good) cholesterol levels. 

Only three percent of participants following the plan developed a decline in the above health markers, compared to six percent in the other group. 

However, blood pressure and glucose – blood sugar – levels stayed the same.
