Junk foods are usually offered anytime and everywhere at very low cost, especially in malls, supermarkets and cinemas. However keep in mind that those fast foods help you save time and money, at the expense of your health. If not consumed in moderation; they can lead to the following health risks:
1. Obesity And Cardiovascular Disease:
The majority of fast food is high in fat and little or no fiber such as fruits and vegetables. Fruits and vegetables help balance a meal high in fat, reduce but not eliminate the adverse effects to the blood vessels. Fast food often contains greasy foods, oils and are fried in many times will contain a lot of influence on cardiovascular system causing diseases like atherosclerosis, myocarditis… As for people with coronary artery disease, it can cause cardiovascular events, such as a heart attack or stroke. This is one of the most negative effects of fast food on the human body that people should learn and make use as soon as possible for good.
2. Increases the risk of dementia
This has been one of the scariest discoveries associated with the consumption of junk food. You may know that insulin is produced in the pancreas and helps in the transportation of glucose to fuel the body. Insulin is also produced in the brain where it helps in carrying signals between nerve cells and forming memories. A study conducted at the Brown University shows that too much fatty food and sweets can substantially increase the insulin levels in our body.
Just like in the case of Type 2 Diabetes, with higher levels of insulin, the brain stops responding to this hormone and become resistant to it. This can restrict our ability to think, recall or create memories, thus increasing the risk of dementia.
3. It can cause chemical changes that can lead to depression
A lot of studies have shown that eating foods high in sugar and fat actually changes the chemical activity of the brain making it more dependent on such foods. A study conducted at the University of Montreal on mice showed that they suffered with withdrawal symptoms after their regular junk food diet was discontinued. In humans, these withdrawal symptoms can lead to the inability to deal with stress, make you feel depressed and eventually you would turn back to those foods to comfort yourself and handle these feelings. Soon, you may be caught in a vicious cycle even before you know it. Also, by consuming too much fast food you may lose out on essential nutrients like amino acid tryptophan, the lack of which can increase feelings of depression. An imbalance of fatty acids is another reason why people who consume more junk food are at a higher risk of depression.
4. Increase Risks Of Digestive Diseases:
A few lettuce leaves and cucumber pickled tuber steak served with could not provide a sufficient amount of fiber and minerals needed for the day. Moreover meat to fried in cooking oil at high temperatures so these valuable vitamins decompose quickly make more and more fast food diets rich in energy that lacks vitamins and fiber. Diet rich in protein, vitamins and minerals at the fast food will increase diseases related to the digestive system, especially colorectal cancer and small bowel cancer. In brief, this is considered one out of the most serious negatives effects of fast food on the human body that people should watch out carefully.
5. Junk Food Affects Your Energy Levels
Junk food doesn’t contain the nutrients your body needs to stay healthy. As a result, you may feel chronically fatigued and lack the energy you need to complete daily tasks. The high levels of sugar in junk food puts your metabolism under stress; when you eat refined sugar, your pancreas secretes high amounts of insulin to prevent a dangerous spike in blood sugar levels.
Because fast food and junk food don’t contain adequate amounts of protein and good carbohydrates, your blood sugar levels will drop suddenly after eating, leaving you feeling grumpy, fatigued and craving sugar.
