Many people confuse fast food with junk food, but both terms are different. Junk food is any food that is low in nutrients, contains added sugar, fats, and salt. It can be addictive and sometimes called food rich in empty calories.

While fast food is any food you get from a restaurant and is served to you in the quickest possible way. Fast food is not healthy most of the time, considering how food restaurants prepare it.

How Does Fast Food Affect Your Body?

Some ingredients in fast food can impart negative health effects on your body. A study revealed the harmful chemicals in fast food. This study confirmed that fast foods are loaded with refined carbs, fats, saturated and trans-fatty acids, sodium, and cholesterol. It’s also poor in rich nutrients.

Consumption of these harmful components can take a toll on your health. Here are some of the fast food unhealthy facts you need to know:

1. Increase risk of cardiovascular diseases

The growing evidence suggests the overconsumption of fast food is linked with the development of heart diseases. Here are some of the cardiovascular threats inflicted by excessive intake of fast food.

An article published in Journal Archives of Iranian Medicine reveals the western-style fast food intake increases the risk factor of coronary heart disease. CHD can worsen the situation and cause chest pain, heart attack and heart failure.

Sodium acts as a preservative and enhances the taste of processed fast food. But its high amount in circulation can raise your blood pressure. Consistent blood pressure can narrow down and harden your arteries, which ultimately leads to stroke.

The American Heart Association declares safe consumption of sodium upto 2300 mg per day. But your single fast food meal in a day alone can take you to recommended levels.

‣ Increased cholesterol levels result in the buildup of plaque

People consuming fast food more frequently have higher levels of LDL cholesterol. Higher levels of LDL (bad cholesterol) put your heart at risk. An article published confirms the association of LDL with atherosclerotic plaque formation.

2. Increases risk for obesity and Type 2 diabetes

The American Heart Association recommends not consuming more than 100-150 calories of sugar per day. The pancreas releases insulin when the sugar level rises in blood.

But frequent eating of fast food (high sugar) results in repeated surges in blood sugar levels. It alters your body’s normal response to insulin, which leads to type 2 disease. Obesity further decreases insulin sensitivity and worsens the situation.
