Unhealthy eating habits such as eating too quickly and consuming too many processed foods can lead to a buildup of undigested food in the intestines. When this happens, the bacteria present in the gut will interact with the undigested food, releasing toxic chemicals and gases. These internal toxins-or endotoxins-may damage the mucosal lining in the gut, ultimately allowing them to enter the rest of the body through the bloodstream.

Over time, such endotoxins put increasing amounts of stress on the body, and organisms such as bacteria, viruses and fungi will seize that opportunity to multiply and flourish. Their toxic waste may soon upset the balance of good and bad bacteria in the intestines, and as a result, organisms that normally inhabit the gastrointestinal tract in smaller numbers without causing harm (such as candida, a typically benign yeast) can proliferate. This can cause problems such as gas and bloating, constipation, abdominal pain and diarrhea.

Clinical research has proven that people who consume a diet high in fiber are less likely to suffer from constipation, irritable bowel syndrome, gastroesophageal reflux disease (GERD), and a host of other digestive disorders. That is because fiber helps to soak up toxins from the intestinal wall and sweep the colon free of debris. Found in fruits, vegetables, legumes, whole grains, nuts and seeds, fiber has also been shown to help prevent disease and support healthy weight management.

Increasing your intake of Essential Fatty Acids (EFAs) may also prove beneficial. These "good fats" include Omega-3 and Omega-6 fatty acids and are found primarily in cold-water fish and flax seeds. In addition to supporting the structure and function of every cell in the human body, EFAs help lubricate the colon and promote gastrointestinal health.

Research into probiotics, the beneficial bacteria that live in your intestines, has produced big breakthroughs in our understanding of health. Because studies have shown that probiotics interact with the immune system to prevent outbreaks of disease-causing organisms and keep the immune cells functioning at full capacity, adding an effective probiotic supplement to your daily diet may be the key to maintaining a healthy balance of bacteria in your intestines and improving your digestive health.

Because enzymes are an essential part of all chemical processes that take place in the body, many people also benefit from taking a daily digestive enzyme. Although the best sources of enzymes are fresh fruits and vegetables, many Americans do not consume enough of these foods on a daily basis. When choosing an enzyme supplement, keep in mind that plant enzymes are best, as they are effective over a broader range of pH levels in the digestive system and thus provide the greatest benefit.
While it's true that everything you put into your mouth will ultimately affect your digestive health, just a few simple changes in your diet can often provide significant benefits. Once you discover what works best for you and your body, you will soon be on your way to enjoying a healthier, happier lifestyle.
