Do in Rome as the Romans do is true for health as well. There is an increasing desire to import health foods from around the world. People are looking for the elusive seaweed from Australia or a berry from Africa or an oilseed from Greece to restore their health. But this may always not be a wise thing, but just a passing fad. The local cuisine of the place that you live, including the local vegetables, fruits, millets and grains are well suited for that place and would have stood the test of time.
Ayurveda recommends eating food that is available within the vicinity of the place that you live to be healthy. This automatically ensures that you eat freshly available seasonal fruits and vegetables that can be easily digested and absorbed by the body to convert into energy.
