  • The American Heart Association emphasizes the importance of eating a healthy diet that is rich in fruits, vegetables, nuts, beans, whole grains, low-fat dairy products, fish, poultry and limited in fatty or processed red meat. The association also suggests limiting sugary soft drinks, salt (sodium), saturated and trans fats.
  • The general rule of thumb for a longevity focused diet is to eat plant-based foods, whole grains, and good fats.

  • Eating until one is 80% full and eating the lightest meal later in the day is also common to people living in the blue zones reflecting the benefit of portion control on longevity.

The Okinawa Diet

  • People in Okinawa follow a plant-driven longevity diet and eat a large majority of their calories from green leafy vegetables and yellow vegetables such as soy beans, tofu, and goya, along with sweet potatoes.
  • Protein comes from small amounts of fish, occasional pork, and mostly from plant-based sources such as vegetables, legumes, and tubers.
