Listed foods with links are my recommended versions. Organic versions of listed foods recommended. Raw meats, eggs, and dairy should not be consumed by the very young, very old, very pregnant, those with compromised immune systems, or the litigious.
The sweeter the food listed, the less of it one should consume. Animal foods, particularly red meat, should be limited. With these foods and nothing more, I believe a person could maintain vigorous, which is to say well above-average, health.
