The foods that grow on plants are the ones we should eat. The more you eat, the less soon you die. In most cases, you can't eat too many fruits or vegetables.
Nuts fill you up with good fat, protein, and fiber. They also reduce heart attacks, and prevent death. Best consumed in moderation, but regularly!
Olive, canola, avocado, soybean, walnut, pretty much all but coconut and palm. Good oils reduce heart attacks. Cold pressed and extra-virgin is a bonus, but don't sweat it.
Lentils, beans, chickpeas are prominently in the diets of all cultures that routinely reach the age of 100.
Grains are good as long as the good stuff hasn't been taken out (fiber) and the bad stuff hasn't been added (sugar/salt). Good in moderation.
