A wholefood diet is a healthy mixed diet in which fresh and non-treated foods as well as wholemeal products take precedence. A diet is only considered wholesome if it contains sufficient amounts of all important nutrients, in the right form and proportion. The concept of full-fledged nutrition goes back to the observations of German food scientist Werner Kollath, who assumed that the less food is processed, the more valuable it is and the healthier it is.
Vegetables play an important role in and are best suited to a wholesome diet. Whole grains, potatoes, legumes, vegetables and fruit as well as milk and dairy products show up on this menu. About half of these items should be eaten fresh and raw. Regional and seasonal products should be given preference. Meat should be eaten sparingly, a maximum of 600 g (1.3 pounds) of meat and sausage per person per week. The consumption of fish twice a week is highly recommended because of valuable omega-3 fatty acids and iodine content.
Drinks should include mineral water, unsweetened teas and diluted juices. Coffee, black tea and alcohol should only be consumed to a limited extent.
The German Nutrition Society (DGE) recommends a complete diet as a permanent diet, as the body is optimally supplied with all important nutrients.
