Meats and EggsMeats (including seafood) and eggs are perhaps the most important components of the Paleolithic Diet. Ideally, the animals from which the eggs and meat come from are fed a natural (to the animal) organic diet. That is, chickens have access to greens, insects, etc, as well as grain. Cattle eat grass and other pasture greenery. Fish should come from the wild, or at least be fed what wild fish eat. In any case, meats should be free of breading of any kind.
Loren Cordain (The Paleo Diet) believes we should seek out low-fat meat sources, while others disagree. His reasoning is that today's meats are much higher in saturated fat so we should seek out low fat meats and then supplement with fats from other sources.

VegetablesVegetables are encouraged, although some versions of the diet except green beans and peas as they are legumes. Some versions simply say that if it can't be eaten raw, don't eat it (though this doesn't mean that it must be eaten raw, only that it should be able to be eaten raw). Potatoes and other starchy tubers (e.g. cassava) is an area of varying opinions.
FruitsFruits are generally allowed. Some advise that people who need to lose weight should limit consumption of high sugar fruits, especially dried fruit and juices. Some say everyone should limit these.
Nuts and SeedsNuts and seeds are generally allowed, though Cordain suggests that those who want to lose weight limit them to four ounces per day. Note that peanuts are legumes and NOT allowed. Some don't allow cashews, since they can't be eaten raw. Unsweetened almond milk and coconut milk are often used as substitutes for dairy.
