Meats, Eggs and Seafood
The food group is where you will get most of your calories. All meat, fish, shellfish, mollusks and eggs are allowed, but there are some guidelines for choosing the right foods for the best results. The most important thing is that these foods are of high quality and prepared with Paleo-approved ingredients.
These sources include olives and oil, avocados (which are a fruit but serve as fat) and buts and seeds (which are described in detail in this section of the site). Since butter is a dairy product and does not improve your heart health, it should be avoided when cooking or preparing foods, use pure olive oil for cooking and grape-seed oil or extra virgin oil for uncooked dressings.
Nuts and Seeds
Nuts and seeds were a big part of the Paleolithic-era diet. All nuts are allowed, with the exception of peanuts, which are legume. Seeds are allowed, including flax seeds, sunflower seeds, pumpkin seeds, sesame seeds and others. If you are frightened by the idea of giving up pasta and rice, the good news is that quinoa is allowed. Not only is quinoa a seed, but it also makes a great substitute for rice, pasta, oats, barley and other grain foods.
Fruits and Vegetables
The fruits allowed on the Paleo diet are those that would have been readily available ( foraged) in the pre-agricultural era. These foraged fruits include berries, such as cranberries, raspberries, strawberries and blueberries. Tree fruits are also a mainstay of the Crossfit/Paleo diet, they include citrus fruits, apples, peaches, plums, cherries, nectarines and pears.
Some condiments are allowed, but they should be limited to those that do not contain sugar or any of the forbidden ingredients. Ketchup, for example, is not allowed; mustard, on the other hand, is made from seeds and usually does not contain added sugar. In general, try to rely on herbs and spices rather than condiments.
Allowed beverages include pure fruit and vegetables juices, but they should be unsweetened versions and consumed in moderation. Water should be your primary beverage. Tea and coffee are acceptable on the Crossfit diet, as long as you use almond mile to lighten them, rather than dairy milk.
