With the super busy lifestyle that everybody is gravitating to, there is less and less time for everything, including cooking and eating. Thus, more and more processed foods are finding their way into our refrigerators, as they can just be picked up and eaten anytime hunger pangs are felt. And, we do not immediately realize that processed foods are devoid of all the essential ingredients. What we end up eating has less fiber, more salt, and more preservatives (generally not very safe for all), all leading to an unhealthy lifestyle.
Refined flour, white sugar, cheese, canned juices, frozen foods, cheese laden pizzas and breadsare all yummy, but not something that is readily accepted and digested by your stomach. Try eating pizza with loads of cheese for two days and experience the bloated feeling for yourself. Not to scare you, but imagine this; you would have to eat an entire medium pizza to get 2 g of fiber. Where as, your body requires about 25 to 40 g of fiber per day for regular health maintenance.
Biologically, our digestive system requires a lot of fiber, which adds to the roughage. This is very important as it helps in digestion and aid in cleansing the bowel later. The function of the large intestine is to remove water and essential ingredients when food passes through it. Junk food passes through quite quickly, thereby, leading to loss of water and ingredients. A lot of digestive issues are also related to lack of fiber in the food, like polyps, colon cancer, irritable bowel syndrome, high cholesterol, and obesity.
Most of us are aware, but tend to ignore the fact that junk food is as the name suggests, junk. There is hardly anything of nutritious value in it. On the contrary, it contains lots of salt, fat and artificial chemicals, which though, make it very tasty, but has zero nutrition value.
Try to eat only junk food for about a week regularly, and you will surely feel:
1. Bloated (a lot of gas due to indigestion)
2. Dehydrated (excessive salt needs more water, which we don't realize)
3. Constipated (lack of fiber leading to reduced bowel movement)
4. Weak and lousy (due to lack of nutrition)
This of course does not include the harmful effects on skin, hair, looks, etc. It does not mean you have to stop eating junk completely and eat only healthy food all the time. The human body is adaptive and can adjust to a lot of variations. It is not wise to try the example above (eating pizza for a week), however, binging on junk food once a week would definitely not hurt. Use your discretion as nobody knows your body as well as you do.
