Hi Inge, thanks for your interest in Jake! I'm sorry to hear that you've been sick for such a long time. With regard to your question, I'll use a part of our FAQ as it seems to answer your question: Jake is food that provides you with all the nutrients that the average human body (covering 95-97% of the population) needs. If you’d like to eat nothing but Jake, that is an option, but you can eat other foods as well.
Not every single body works like most (95-97%) of the population. Some people may be more susceptible to certain nutritional deficiencies, e.g. due to illness. Therefore, it is always important that you listen to your body and act on it. We recommend taking a look at our nutritional information and deciding what use of Jake suits your specific needs best. If you are in doubt, e.g. because your medical situation requires a specific diet, always consult your doctor.
