Constipation is a condition in which an individual has difficulty passing stools or might have infrequent bowel motion patterns. There are many causes of constipation. Some of them are hypothyroidism (low thyroid function), slow transit time in colon, irritable bowel, food allergies or something as simple as lack of fiber in diet
There are certain foods that can cause or aggravate constipation. These are foods high in fat, and low in fiber. Some of these food culprits are dairy, chocolate and fried foods. Dairy contains casein which binds to water making stool harder to pass. Chocolate contains cocoa butter which also binds to water making stools hard to pass
You need to eat foods high in fiber to avoid constipation as fruits and vegetables. Watch the high glycemic fruits. The most important point is to drink plenty of water. Fiber adds bulk to the stools making it easier to pass. Other tidbits of information which can help constipation is daily exercise, and avoiding caffeine
