The basis of natural nutrition is wild, raw plan food.
Wild food connects you immediately to the land. Eating wild food growing in your area acclimates you to the environment.
Wild greens have the highest energy frequency of any food.
Seaweeds and sea vegetables of all kinds have never been cultivated. They are still in their wild unadultered form.
Wild fruits are the sustenance of the immortals.
Common fruits which are close to the wild state and/or are extremely viable. when grown from seed include: avocados, cherimoyas, crab apples, guavas, heavily-seeded citrus fruits, jackfruits, mangos, most melons, most peppers or chilies, papayas, peaches, tomatoes, tomatilloes, olives, white sapotes and others.
Common vegetables which are close to the wild state and/or are extremely viable when grown from seed include: dandelion, garlic, kale, lamb's quarters, malva, mint, mustard, onions, watercress, wintercress and others.
One of my favorite wild foods is malva (mallow). Malva seems to love growing on the outskirts of civilization - in canyons, back alleys and back yards. Malva is one of those phenomenal greens that tastes incredible when eaten alone. In the winter I typically start off the morning with fruit blended with superfoods, then eat malva for lunch and have a salad with some raw plant fats for dinner along with vegetable juice.
Common nuts and seeds which are close to the wild state and/or are extremely viable when grown from seed include: coconut, macadamia, quinoa and sunflower.
