The effects of junk food.
1.It causes fatigue and weakness.
Junk food lacks most of essential nutrients like proteins and vitamins required for maintenance of overall health and functioning of all the systems in your body. Although it makes you feel full and satisfied, it fails to provide you with instant energy, making you feel weak and tired after a while. If you eat junk food items for all your meals of the day over a period of time, you could be suffer from chronic fatigue. Junk food can lower your energy levels to an extent that it may become difficult for you to even perform your daily tasks.
2. It affects the brain function.
One week of eating junk food is enough to trigger memory impairment in rats. Recent research suggests that bad fats (trans fats) from junk food tends to replace healthy fats in the brain and interferes with its normal signalling mechanism. Studies in animals have also shown that fats from junk food slow down the ability to learn new skills.
3. It can damage your liver.
Junk food consumption over a period of time can have similar harmful effect on the liver as alcohol consumptions does. A study reported that people who ate junk food and shunned exercise showed changes in liver enzymes within four weeks. These changes were similar to those observed in people with alcohol abuse. According to some studies, it’s the high level of trans fats found in a number of junk food which cause liver dysfunction due to deposition in the liver.
