You know what that is? You feel tired and nervous. Somehow you feel the joints, the muscles are tense. This can indicate an overacidification - then acid and bases are out of balance in your metabolism. Acid-forming ingredients such as meat, eggs, bread or pasta can disturb this balance. The body then tries to regulate the excess acid - and this can lead to discomfort. What helps? No pills, no medicine, but an alkaline diet! Fortunately, many foods we like are alkaline: potatoes, fruit, vegetables and mushrooms. And if we use them cleverly in the kitchen, we can even have a balanced diet with meat dishes. This is the recipe for success of GU's acid-base cookbook and brings the metabolism into balance. Whether breakfast, snacks, salads, soups, main courses or desserts - all dishes positively support the acidity.
