The dietary habits adopted by developed countries over the last centuries are largely responsible for many of the chronic diseases that are now commonplace in Western society.

Diseases such as coronary heart disease, diabetes, high blood pressure, and cancer of the colon are virtually unheard of among the few hunter-gatherer populations still remaining in the world.

The stone age diet is based on the foods that our hunter-gatherer ancestors would have eaten before they became farmers.

Even over the last fifty years, our food has drastically changed. Where once our food was made up of simple, natural foods with minimal added ingredients, our food now contains a multitude of different ingredients.

Often it can be hard to even find modern-day food that does not contain some form of milk or wheat, which are common triggers in food allergies, and this leads to people eating the same ingredients every day and often at every single meal.

The stone age diet is nutritionally balanced and a very low allergen diet ideal for people who suffer from food allergies or food related ailments.

The foods you can eat on the stone age diet should be from natural sources and include items such as fruit (except citrus), fresh fruit juices (except citrus), all game and fish, free-range eggs, all vegetables, fresh vegetable juices, fresh nuts (except peanuts), herb teas, natural seasonings (salt, black pepper, herbs) and bottled or filtered water.

The foods you must avoid on the stone age diet are milk in all forms, milk products, cereals and their related products, any form of sugar, domesticated animal meat (meat from pigs, cows, sheep etc.), chicken, eggs (unless free-range), citrus fruit, alcohol, coffee, tea and all manufactured foods such as canned, packaged, bottled foods and ready-meals, processed meat or fish, chocolate and cocoa products, spices and tap water.

The above list may seem restrictive but you will find your health and well-being dramatically improves just be removing the foods to avoid from your diet.

There are also some exceptions which you are allowed to eat on the stone age diet which do fit in with our modern lives and dietary practices. Live low-fat yoghurt in moderation is a good addition to the diet and some grains which are well tolerated, even by those with a food allergy, are rice and millet.

If alcohol needs to be consumed (perhaps you're at a wedding or celebration) then a small amount of dry white wine or real ale can be taken.

The stone age diet is based on natural, nutritionally rich foods and following the dietary habits it provides will ensure you reap the benefits and achieve a strong, fit and healthy body.
