Eat up to 3 ounces of fish daily
The Adventist Health Study 2, which has been following 96,000 Americans since 2002, discovered that people who ate a plant-based diet and included a small portion of fish up to once a day were the ones who lived the longest. In the Blue Zones overseas, fish is a common part of everyday meals. For the most part, the best fish choices are middle-of-the-food-chain species such as sardines, anchovies and cod, which aren’t exposed to high levels of mercury or other chemicals.
