Humans who lived in the Paleolithic era varied in diet depending on what was available in the natural world where they lived. Some people consume animal foods that are low in calories, others eat vegetables. To avoid confusion, you can use the basic guidelines below as a start from john barban.
Meat: Beef, goat, chicken, turkey, pork, etc.
Fish and seafood: Salmon, shrimp, shellfish, and try fresh fish
Eggs: Eggs labeled with omega-3s
Vegetables: Broccoli, kale, onions, carrots, and tomatoes
Fruits: Apples, bananas, oranges, pears, avocados, strawberries, and blueberries
Tubers: Potatoes, sweet potatoes, and turnips
Nuts and seeds: Almonds, walnuts, hazelnuts, sunflower seeds, and pumpkin seeds
Healthy fats and oils: Olive oil, coconut oil, and avocado oil
Salt and spices: Sea salt, onions, turmeric and rosemary
It would be better if you choose organic food ingredients, but if it is not possible, just avoid foods that are less healthy, like some examples below:
Sugar and fructose corn syrup: Soft drinks, fruit juices, sugar, sweets, pastry products, and ice cream
Processed wheat products such as bread, pasta, oats, and barley
Legume: Nuts, lentils and the like
Processed milk: Low-fat milk is not recommended for those on the Paleo diet because it requires high-fat milk.
Vegetable oil: Soybean oil, sunflower oil, corn oil, cottonseed oil, and others
Trans fats: These fats are found in margarine and processed foods
Artificial sweeteners: Aspartame, cyclamate and saccharine.
Processed foods: All foods that have excess additives as well as foods labeled “diet” or “low-fat” including artificial substitute foods
In the Paleo diet, there are no standard rules that limit you from eating certain foods. The important thing is to avoid processed foods and switch to natural food products.
