The new year can spur the urge to make changes to your lifestyle. Diet advice tends to be heavily marketed this time of year with claims of benefits to health and self-esteem. But diets are often restrictive and exclusionary, and even if they provide short-term benefits, they tend to be unsustainable in the long term and in some cases can lead to disordered eating. Scientists and nutrition experts recommend looser, more inclusive approaches to eating, such as the pesco-Mediterranean diet, an eating pattern that’s high in plants, nuts, whole grains, extra-virgin olive oil, and fish or seafood. Writer Markham Heid explains why combining healthy eating approaches — like, say, the pesco-Mediterranean diet and intermittent fasting — might be the optimal human diet.
