Swiss Secret to Optimal Health

swiss-secret-optimal-healthThe Swiss Secret to Optimal Health is written by Thomas Rau, M.D. the Chief Medical Director of the Paracelsus Clinic in Switzerland, which specializes in natural medicine.

In this book Rau discusses the role of nutrition for maintaining health as well as outlining his theories on how a detoxification diet can help to eliminate disease.

He claims that when dieters follow his program, not only will they lose weight, but they will also experience other benefits such as a stronger immune system, total body cleansing, increased energy, and psychological rejuvenation.

In addition he says that his approach will assist with the elimination of chronic health conditions such as diabetes, arthritis, and allergies.

Swiss Secret Diet Basics

Rau states that eighty percent of the cells of the immune system are found in the intestine, so in order to maintain health and support cellular rejuvenation, it is necessary to provide the body with high-quality nutrition.

The diet commences with an intense one-week period that Rau describes as a controlled fast in which you eliminate the intake of sugar, caffeine, processed foods, alcohol and animal protein. At the same time you will greatly increase your consumption of vegetables while consuming smaller amounts of fruits and whole grains.

Rau says, “These foods provide a large amount of vitamins, trace elements, essential amino acids and essential fatty acids that are crucial for restoring ideal pH levels and loosening toxic blockages”.

After the first week, dieters follow a three-week plan where larger portions are permitted and vegetables remain plentiful. The Swiss Secret program is not strictly vegetarian and each week you are permitted to include several portions of fish or chicken as well as moderate amounts of sheep and goat cheese.

Recommended Foods

Fresh vegetable juice, vegetable soup, steamed vegetables, salad, apples, grapefruit, whole grains, olive oil, flaxseed oil, lemon juice, seeds, nuts, legumes, fish, chicken, sheep and goat cheese, herb tea.
