The good News first: An alkaline diet can actually work. However, only for the reason that the recommended foods – vegetables, salads, fruits, fruits, etc. – apply anyway as healthy (not harmful according to the alkaline diet are supposedly acid-forming foods such as sugar, grain products or meat). The theoretical concept behind the alkaline diet an alkaline environment in the body, to stimulate digestion, the well – being and weight loss without a scientific basis. Because on the one hand, our body adjusts with a sophisticated buffer system, the pH-value of blood very exactly to a value between 7,35 and 7.45, so slightly basic. It does not matter what we eat, the diet has zero effect on the pH of the blood! In addition, the environment in the gastro-intestinal tract strong to moderately acidic, and some of the most important building blocks in the body are also acids: fatty acids and the genetic material of the DNA molecule, for example.
side effects : A one-sided alkaline diet can overwhelm the body as well as a one-sided acidic diet.
