The digestive system processes all the foods that we eat. It breaks down food into substances that our body needs. It also separates materials that are harmful and considered wastes. But the digestive system can also be damaged by the very same foods that we eat. There are certain kinds of food that are harmful to the digestive system. For example, disaccharides from sucrose can give problems in the colon. Some people do not produce enzymes that break down disaccharides so they remain in colon where microorganisms feed on them and make them rotten. Highly acidic food can also lead to stomach problems. They can make the stomach environment highly acidic which could lead to some form of ulcer.
Avoid foods high in disaccharides and polysaccharides. As explained above our body needs a special enzyme to digest disaccharides and polysaccharides. Without these enzymes, disaccharides and polysaccharides become deposited in the colon. This causes digest stress.
Avoid food rich in phytates like grains. Phytates are very hard to digest. They also cause allergic reactions. Furthermore, they also deprive the body of important minerals like calcium and iron.
Many vegetable oils contain trans fats which contribute to inflammation in the digestive tract. Instead of using vegetable oils, it is better to use cod liver oil. It contains anti-inflammatory omega 3 fatty acids. It also has vitamins A and D that helps fight inflammation.
Have soups and stocks from animal bones like chicken and beef. These soups and stocks contain anti-inflammatory and anti-microbial properties. People with digestive problems often suffer from fungal, viral and parasitic infections. Soups and stocks will help you fight these off. They also contain nutrients good for the digestive tract.
Not all bacteria are bad. There are some that your body actually needs. Healthy bacteria or probiotics are important to be able to fight bad bacteria. They also help seal and clean up the gut. You can get them from lacto-fermented food like yogurt.
Avoid highly acidic food. Sour food may contribute to hyperacidity. Having too much vinegar for example can aggravate stomach ulcers.
Drink lots of water. Water aids in the digestive process. It also aids in removing toxins. Alkaline water can also dilute the digestive juices and reduce their acidity.
Just as the digestive system processes the important nutrients that other body systems need, it also needs important nutrients to protect its own health. And since it is the system that receives the food that we eat, it also gets affected by harmful chemicals that we take in. So it is best to eat healthy foods for optimum digestive health.
