Most people's diets are woefully inadequate for providing proper nutrition. Even good diets fail to deliver sufficient levels of nutrients. The Vitamin Cure book series highlights the safe and clinically effective use of vitamin supplements for a variety of illnesses. Research continues to prove the immense value of vitamins for maintaining health and fighting disease. The Vitamin Cure books, written by authors who are recognised experts in their field, deliver authoritative, up-to-date and practical information on taking vitamins for particular health problems. Those that think that they are not affected by digestive issues may consider them less serious than many other health problems. This is far from the case, as those who suffer from them can report. And digestive health has a direct impact on many, very serious illnesses aside from those directly apparent, such as indigestion, gastroesophageal reflux disease (GERD) and ulcers. Digestive health is critical to your health in general and has a direct impact on all of the systems and organs in your body. This readable guidebook will assist anyone suffering from digestive issues or those who just want to make sure that they are providing optimal nutrition to their bodies. It explains the major digestive systems, describes their structure and functions, discusses the health problems that can develop in each system and their causes and addresses available medical treatments. It covers a wide range of problems from canker sores to GERD, inflammatory bowel disease, Crohn's disease, gluten allergies, and gallstones to cancer and more. The focus is to give readers straightforward, clear explanations on how and when to treat digestive issues with healthy, natural nutrition and vitamin therapies.
